Starting from the hypothesis that students schooled in an English-medium education system do engage in friendly argument in English with peers, this paper inquires into the question of whether argument practices displayed in friendly interaction would be reflected in some form in formal academic writing that calls for the reasoned projection of a point of view. Students’ texts from two discourse situations, one informal and the other formal, were studied for the presence of three argument practices: stance assertion moves, stance support moves, and the rhetorical use of topic knowledge in argument support. Move analysis revealed that the informal arguments featured fairly sophisticated stance assertion and support moves that included the rhetorical deployment of available topic knowledge. While argument in the formal text, specifically an academic essay, featured stance assertion and support moves, deployment of topic knowledge for stance support was executed with less directness. The pedagogical implications of these findings are discussed to consider means of building on students’ friendly argument practices with the goal of developing competencies in argument construction for academic writing tasks. # 2008 Elsevier Inc.

Keywords: Argument in student writing; Argument in online forum; Teaching expository writing; Academic writing Introduction The argument that students’ out-of-school literacy practices should be given value in school settings has been advanced by literacy scholars with an interest in non-schooled literacies (Kramer-Dahl, 2005; Street, 1997).

Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 school literacy competencies that can be harnessed in the classroom for the development of thinking and writing skills for academic purposes. If students participate in non-classroom activities that involve oral discourse and reading/writing processes, the knowledge and skills they exercise in these activities may be relevant to school-based reading and writing tasks. We should therefore be sufficiently interested in students’ out-of-school literacy behaviours as to inquire into their nature and their potential role in classroom lessons aimed at developing academic writing skills. Argument in friendly interaction is one form of social behaviour that may involve discourse practices that are relevant to classroom writing tasks that call for the adoption and development of a writer position on a topic or issue. The texts produced in such tasks belong to the category of writing referred to as expository writing, which has been defined as texts that state a point of view or thesis that is subsequently developed through arguments (Rothery, 1996; Schleppegrell, 2004). Going by this definition, argument in the sense of advancing and developing a point of view is expected from students in many school- and university-based academic writing tasks, an expectation not limited to argumentative essays. Many school and university-based expository writing tasks, while not expressly argumentative in the sense of requiring the adversarial defence of a personal point of view against an opposing view, call for construction of a network of related supporting claims aimed at enhancing the acceptability of the writer’s stance on a topic or issue (e.g., a book review written for the English composition teacher, a master’s degree student’s research proposal). In this paper, the term ‘‘academic writing’’ is used with the meaning of ‘‘expository writing’’ and includes the argumentative essay and any writing in which a thesis or point of view is sustained through acts of interpreting, arguing, and persuading, acts recognised as genre practices in academic writing (Woodward-Kron, 2002). Since support of a point of view is intrinsic to expository writing, the discourse practices of stance assertion and stance support in argument in informal contexts could play a role in the development of students’ academic writing competence. This paper examines excerpts of Singapore students’ friendly argument to discover if there are discourse moves that can be honed for argument construction in expository essay writing. It then examines a student’s academic essay to observe the transformations, if any, that the discourse acts of friendly argument may undergo when enacted in the formal context of the academic essay. The aim of studying argument practices in the two different contexts is to explore the question of how writing teachers might harness students’ expertise in friendly argument for the purpose of developing competence in expository essay writing. What adjustments to oral, informal stance taking or stance support acts, for instance, need to be taught so that students can project a consistent stance in an academic essay? The motivation for studying students’ informal arguments came from Singapore teachers’ reports of the challenges of teaching expository/argumentative essay writing in secondary school. These were secondary school English language teachers who attended an in-service course I have been conducting for four years on the teaching of expository writing. A recurrent thread in their sharing of classroom experience may be summed up in the oft-heard statement: ‘‘My students can’t argue’’ which, on further inquiry, usually refers to the non-elaboration or inadequate elaboration of argumentation claims, including the use of topic knowledge for elaborating and supporting claims (i.e., Students do not have the knowledge). The teachers’ perception that their students ‘‘can’t argue’’ raises the need for verification. Students in an English medium education system such as Singapore’s who use English in and outside the classroom for peer interaction must, at times, engage in friendly argument with each other, possibly enacting the argument moves of stance assertion and stance support since, A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 239 according to Schiffrin (1985), these are characteristic acts whenever individuals advance and support disputable or disputed positions. Perhaps these moves exist in students’ informal arguments but are not evident in their expository essays in a form recognisable by teachers as valued practices of written argument. A close examination of students’ informal arguments is needed to determine if they enact the defining argumentation discourse practices of stance assertion and stance support and, if they do, how these practices are constructed. If students’ informal arguments have stance assertion and stance support moves, we would expect some semblance of these acts to appear in their academic essays. A scrutiny of students’ academic essays would reveal if the discourse practices of informal argument are deployed and how they are deployed in argument in the formal context of school-based writing. Furthermore, since interactants in argument typically rely on their store of topic knowledge as a source of grounds or evidence for stance support, we would expect students to put their knowledge of the topic to rhetorical use whether they are engaged in friendly argument or in the more formal argument of academic writing. The need for evidence of the nature of students’ discourse practices in argument motivated the analysis of students’ formal and informal arguments reported in this paper. The analysis was guided by three specific questions: 1. Are there stance assertion and stance maintenance moves in the text studied? 2. If there is stance support, what strategies of support are evident? 3. Is topic knowledge put to rhetorical use in stance support instead of appearing to be merely recounted? Findings from studying argument moves in students’ friendly interaction and in academic essays could have useful implications for the teaching of academic writing at school and university. The observation that the knowledge students bring into the classroom is little used or valued by teachers (Austin, Dwyer, & Freebody, 2003) suggests that students’ social discourse skills hold potential waiting to be tapped by teachers interested in improving their students’ academic writing competence. Informal argument practices might, for instance, be harnessed in writing lessons to show students how to augment their existing argumentation skills to align with the conventions of argument in academic essay writing. This and other possible pedagogical implications of the results in the current study are discussed in the final section. But before that, in the sections immediately following this introduction, the theoretical framework of the study is set out, previous studies on students’ academic writing are briefly reviewed, the method of move analysis is explained, and the findings relating to argument moves are reported. Academic writing from a socio-cultural perspective The theoretical perspective of writing adopted in this paper is the view that sees literacy (reading and writing) as social practice, one that is ‘‘always embedded in socially constructed epistemological principles’’ (Street, 2001, p. 7). In the context of students’ writing in academic settings, writing as social practice involves conscious or sub-conscious knowledge of the normative writer-reader interaction practices of the academic discourse community. The normative discourse practices include discipline-specific cultural attitudes towards knowledge and ways of using book knowledge to construct and sustain writer positions. Viewing writing as social practice does not deny that there are cognitive processes involved in writing and reading, but these are ‘‘concomitants of what is a social activity’’ (Luke & Freebody, 1997, p. 3). The 240 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 thinking processes that drive effective writing are shaped by the conventional textual practices and value system of the discourse community in which the written text will be read and judged. Viewed as a social activity with a set of conventional textual practices, expository writing in academic settings is characterised by the social interaction acts of stance taking and stance support. Asserting and justifying a stance are dominant practices in academic writing because such writing is ‘‘a process of interpreting, arguing, criticizing, and . . . persuading the disciplinary community to accommodate new claims’’ (Woodward-Kron, 2002, p. 516). The same process of interpreting, arguing, and persuading is played out in informal interaction, whether face-to-face or online, whenever the discourse features disputed or disputable topics. There are certainly differences in the way argument is performed in oral friendly encounters and in formal written academic essays, two significant areas of difference being metadiscourse—how writers engage with readers (Hyland, 2005)—and type of acceptable evidence in claim-support. Nevertheless, the point remains that the basic component acts in everyday argument and in the academic essay are stance taking and stance support. Theoretical views of writing influence approaches to the teaching of writing, an issue of relevance here because this study was motivated by the question of whether students’ social argument practices can play a role in the development of expository essay writing ability, a question we will return to in Discussion section. From the theoretical perspective of writing as social practice, the teaching of argumentative writing for academic functions should prioritise the socialisation of students into the discourse behaviours valued by teachers and professors. To expedite the process of socialisation into academic genres, explicit instruction of discourse moves through articulation of the tacit, underlying value assumptions and explicit teaching of the linguistic features for realising the conventions of the genre have been proposed and trialled in classrooms (Cope & Kalantzis, 1993; Rothery, 1996). Recognised as part of the critical literacy movement (Luke & Freebody, 1997), genre-based approaches to teaching writing have been advocated for the promise they hold of empowering students for academic success through explicit instruction that brings to conscious attention ‘‘dominant practices and foregrounds . . . dimensions . . . which had previously remained invisible’’ (Lillis, 2006, p. 32). Despite the scepticism of some literacy scholars who believe that socio-cultural practices in written discourse cannot be taught (Freedman, 1994), the genre approach has won adherents among teachers owing largely to the positive results of Australian studies (e.g., Richardson, 1994; Rothery & Stenglin, 2000) that investigated the application of the Australian school of genre theory in classroom settings. Argument practices in students’ academic writing As noted in the introduction, many academic writing tasks involve the process of taking and maintaining a stance on a topic or issue to persuade the reader to accept the writer’s stance as reasonable. This section’s brief review of recent studies on students’ writing is aimed at building a composite picture of the argument behaviours in student-generated expository texts. The papers reviewed here are predominantly studies of the writing of non-native English speaking students, the reason being that I have been drawn to such studies as some of the Singaporean students participating in my study speak a language other than English outside the classroom. Arguing may be a socially learnt skill that is acquired at an early age, a view suggested by studies of children’s written arguments reviewed by Piolat, Roussey, and Gombert (1999). Piolat et al. (1999) concluded in their review that before the age of twelve, children are capable of writing arguments justifying their point of view though the ability to integrate counterargument A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 241 into their writing develops a little later at age thirteen or fourteen. A study of fifteen- to sixteenyear old Singapore students’ postings on a school online forum revealed arguments that included fairly sophisticated counter-argument moves such as anticipating opposing views, and partial concession of these views before a rebuttal (Chandrasegaran & Kong, 2006). Since these students had not been explicitly taught the cognitive strategies and genre practices of argumentative writing, one may conclude that their argument moves emerged from the exigency of peer-to-peer social interaction over debatable topics that demanded the articulation and defence of a point of view Analyses of students’ expository essays have found discourse behaviours that vary somewhat from the stance assertion and development moves reported in the studies referred to above. For instance, moves that address opposing or alternative views, realised as counter-arguments in the forum postings study (Chandrasegaran & Kong, 2006), appear in a different guise in Asian students’ essays analysed by Hinkel (1999). Hinkel reports the practice of ‘‘setting up opposing positions, making a statement, and then confuting it, as in Some people believe xxx, and others think yyy’’ (p. 98). Counter-arguments were commonly acknowledged ‘‘in a sentence or a phrase’’ (p. 99) without elaboration. The practice of setting up opposing positions may have its roots in the emphasis school writing teachers place on ‘‘balance’’ in essays, a value reflected in one Singapore teacher’s enthusing over ‘‘balanced arguments’’ as ‘‘a real treat’’ to read (Lee, 2006, p. 209). School writing lessons may have imprinted in students an interpretation of ‘‘balanced argument’’ that is limited to the mere statement of opposing views. Another discourse practice observed in students’ expository writing is postponement of the position or thesis statement. In a study of the academic writing of a Japanese master’s degree history student at a British university, English (1999) observed that in an essay requiring an assessment of the weight of reasons for a historical event, the student stated her assessment only in the essay’s final paragraph. Preceding the assessment were paragraphs that appeared to her tutor to be a listing of factors leading to the historical event but which, based on the contrastive rhetoric studies of Hinds (1990), could be intended by the student to be her ‘‘reasons’’ in support of her position. From previous studies of students’ essays (Cai, 1999; English, 1999; Hinkel, 1999), we might infer that students do use topic knowledge for essay development, although the manner in which the knowledge is presented appears too much like mere recital to the reader expecting discourse moves characteristic of the Anglo-American model of the academic essay. Topic knowledge took the form of a listing of reasons leading to a historical event in the history essay by the student in English’s (1999) study, presumably intended as support of the student’s evaluative stance, which is stated in the essay’s concluding paragraph. The student in Cai’s (1999) study used book knowledge of the French Revolution to suggest a claim about the origin of the concept of equality. The college students in the two studies just referred to were writing in response to a tutor-set task for a course with a set of prescribed reading texts. This context may have given rise to the writer’s goal of demonstrating to the tutor evidence of having studied the course readings, resulting in so much attention being channelled to topic knowledge that the intention to argue a position is submerged. When writing is not tied to a teacher-imposed task, as in the writing of a post-graduate thesis, the rhetorical use of topic knowledge may be more apparent, possibly due to the influence of a personally felt argument goal arising from writing on a self-selected topic. In a study of two post-graduate students’ moves in the discussion chapter of their theses, Chandrasegaran (2001) found that both students, one of whom was a less competent writer than the other, used their topic knowledge of previous research in the field for the purpose of validating their own interpretive claims. 242 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 Although the discourse behaviours reported above were observed in the texts of non-native English speakers (NNES) – specifically, Asian student writers – similar observations have been made in the texts of native English speakers (NES) (e.g., Flowerdew, 2001). A study of students’ argumentation practices in casual and formal situations could yield results with implications for the teaching of expository writing to both NES and NNES students. While studies of students’ academic writing have documented deviations from the discourse behaviours regarded as conventional practices in Anglo-American expository writing (e.g., Cai, 1999; Chandrasegaran, 2001; English, 1999), little or no attention has been paid to the question of whether informal arguments among students feature some version, at least, of the stance support behaviours that are expected in expository essay writing. It is possible that verbal acts of defending a personal stance on a disputed issue, including the rhetorical use of topic knowledge as grounds for a stance, occur naturally in friendly argument but are not realised in formal academic writing in a form that is recognisable to tutor-readers as stance support moves. It is equally possible that schools’ disinterest in students’ literacy practices in out-of-class contexts has built the belief among students that the argument practices of peer-to-peer interaction have no place in formal expository essay writing. The potential usefulness of more knowledge of students’ out-of-school discourse practices and the scarcity of investigations into student–student interaction outside formal lessons (Austin, Dwyer, & Freebody, 2003) are reasons for the current study, which seeks to examine the nature of argument acts in the friendly online forum postings of a group of students. This study was carried out with the hope that the results, juxtaposed with those from an examination of argument moves in a formal essay, would make some contribution to discussion among writing researchers and teachers on the potential value of harnessing students’ out-of-school discourse behaviours for the development of their writing competence. Method To study the nature of stance taking and stance development behaviours in students’ arguments in formal and informal contexts, two types of student-generated texts were analysed for discourse moves in constructing stance and stance support. The texts for studying informal argument moves consisted of messages posted by a group of Singapore secondary school students on an online forum. Online forum postings were chosen because they provided a visible written record of the dynamics of stance taking, stance challenge, and stance defence among a group of students away from the judgemental presence of a teacher. The text for studying formal moves was an academic essay written by a Singapore master’s student for a course assignment. The choice of secondary school students’ forum postings served my primary objective of inquiring into the potential use of out-of-class discourse practices for raising student competence in school-based expository writing. The academic essay, however, had to be sourced from a university course for the two reasons explained below. Firstly, the secondary school students who participated in the online forum were rarely set expository essay topics for English composition due to a preference among Singapore English teachers of O-level classes for narrative topics. Although some teachers may be beginning to appreciate the value of teaching expository writing as a result of changes in the English examination paper, at the time of this study the preference for narrative topics was prevalent enough to draw a call from a reader of The Straits Times to teachers ‘‘not [to] discourage O-level students from attempting the argumentative writing topic in their English paper’’ (Ng, 2006). Without sufficient experience in formal expository writing, the students who participated in the online forum may not have been able to do more than re-enact their informal argument A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 243 behaviours if asked to write an expository essay expressly for the purpose of this study. Moreover, the conventional limit of the school essay of 300–500 words (the O-level examination requirement) could preclude the full range of possible stance maintenance moves, whereas the 3000-word post-graduate essay potentially offered scope for manifestation of more types of, and more elaborated, stance support strategies. The second reason for choosing a university student’s essay was that the third research question (whether topic knowledge is put to rhetorical use) required an essay situated in a subject of study so that domain-related topic knowledge in the essay could be easily identified. Topicspecific knowledge of any depth is generally not required nor expected in O-level type writing tasks, as these typically feature everyday topics within the experience of fifteen- to sixteen-yearold students writing under examination conditions without access to external sources of knowledge. Since the objective was not to compare students’ ability in argument construction but to observe the nature of argument moves in two different environments, the difference in the education level of the forum participants and the essay writer was considered less material than the need to observe argument practices in situ, in their natural setting rather than in an artificial task concocted for this research. More detailed information on the two texts and their writers follows. The forum postings, totalling about 2000 words, were written by three upper-secondary school (high school) male students who were among the active participants in a school-administered online forum. The topic of discussion was one that had been raised in the local media: which fighter plane the government should purchase. Although hosted by the school, the online forum was an informal platform where students could raise any topic for discussion and express their views without being overly concerned with grammatical accuracy or quality of content, as would be the case in the formal context of classroom essay writing. The English language proficiency level of the authors of the postings may be described as above average to high. English being the medium of education in all mainstream schools in Singapore, these students had been reading, writing, and interacting in English in the classroom since their first year in primary school. They were comfortable using English in social interaction with their peers, as the local speech register of their forum messages attests. They were quite capable of switching to a more standard variety of English in classroom writing tasks, producing coherent texts that were easily comprehensible, though not always free of grammatical error. The academic essay was written by a master’s student, referred to as Student L in this paper, for an academic writing course for post-graduate students. Her school educational background was similar to that of the forum participant students—English medium schooling from primary through secondary in government (public) schools. She was capable of moving effortlessly between the informal local variety of English and Standard English. Student L’s essay was an assignment that required students to write a 3000-word essay justifying their choice of the research problem they would be investigating for their master’s thesis. The writing task allowed the student to choose her topic in much the same way that the forum participants could choose the topic of discussion to respond to. In keeping with the assignment instructions, Student L’s essay was accompanied by a commentary describing her intended moves and explaining the motivation for her choice of meanings and organisation decisions. The rationale for requiring the commentary was to provide a channel for students to demonstrate explicitly the genre practices and cognitive processes learnt from the academic writing course. Student L’s essay and commentary made quite plain that her goal was to argue the validity of a proposal to research the effectiveness of teaching pre-university students to perform evaluative acts during writing as a means of improving their examination performance in the 244 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 comprehension paper in the subject known as General Paper. As a teacher of General Paper, Student L spoke and wrote English with native-like proficiency. (The General Paper is a core subject in the Singapore-Cambridge A-level examinations administered by the University of Cambridge Local Examinations Syndicate and the Ministry of Education of Singapore. Paper 2 of the General Paper is a comprehension paper testing the skills of analysis, interpretation, and evaluation.) The identification of stance assertion and stance support moves in the texts studied was guided by the definition of a move as a verbal act or series of verbal acts expressing meanings aimed at accomplishing a high-level social-rhetorical goal the writer has for the text. This definition is derived from Swales’ (1990) use of the term ‘‘move’’ in his ‘‘Create a Research Space’’ model for article introductions (p. 141) to account for the ‘‘rhetorical movement’’ (p. 140) as the writer builds the text to argue the significance of the research reported in the article. The description of the move performed by a clause or group of clauses in a text is determined by its function with reference to the writer’s whole-text goal, which is indicated through a combination of implied or explicit statements of authorial intention and the social context of the writing task. For example, allusions in the closing sentence of a paragraph to the writer’s overall position on an issue would indicate a Maintain Focus on Position move. A list of moves expected in written arguments was drawn up to guide text analysis (Fig. 1). The selection of items for the list was informed by the findings of a study of students’ argument moves in an online forum (Chandrasegaran & Kong, Fig. 1. Stance-taking and stance-support moves. A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 245 2006) and by my observations, as a teacher of academic writing, of university students’ written arguments. To determine if topic knowledge was put to rhetorical use in the students’ texts, topic knowledge was defined as information about the issue of discussion or argument or knowledge about topics which the writer had introduced into the discussion. Topic knowledge was categorised as put to rhetorical use if it played a contributory role in explaining, maintaining focal attention on, or supporting the writer’s position on the issue of discussion or argument. An example of topic knowledge serving a rhetorical function is the citation of a source as evidence of the validity of the writer’s claim. Topic knowledge identified in the texts as not serving a rhetorical function was information that was recounted without an explicitly indicated purpose with reference to the writer’s overall intention in the argument, or an implied purpose and relevance which a reader can retrieve from the context. Findings Stance assertion and stance support moves were found in both forum postings and the academic essay, thus providing an affirmative answer to the first question asked in this study. From Table 1, where a tick against a move represents its occurrence at least once in the text, it can be seen that support moves found in both forum postings and the essay include citing authority, rhetorical use of book knowledge, and appealing to shared values in the writer’s and reader’s discourse community such as patriotism (in the case of the forum postings) or topic significance (in the academic essay). Counter-argument moves were found in the forum postings but not in the academic essay although there was scope for such moves. Since Student L’s essay was arguing for the need for research into the explicit teaching of interpretive discourse acts as a means of improving students’ answers in the General Paper, there was scope for addressing opposing views that doubt the viability of such instruction or believe in alternative explanations (e.g., poor grammar) for students’ unsatisfactory answers.

Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 Although stance-support moves were found in the two genres, there was a difference in how they were signalled. In the forum postings, intentions to support a position and the support function of clauses were explicitly indicated. In the academic essay, stance support intentions and support functions in stretches of text were often implied or obliquely expressed rather than explicitly signalled. For example, the intention to support a claim for the validity of the writer’s proposed research into the teaching of interpretive acts was only alluded to (‘‘Her study [cited in the preceding sentences] adds value to my research area’’ [see Sentence 42, Fig. 2]) but not elaborated. As Fig. 2 shows, the sentence containing this allusion to Student L’s own study (Sentence 42) ends her argument in the section, the next paragraph being the start of a new section on a different topic. The reader is thus left to work out how the cited work bolsters Student L’s claim that teaching interpretive acts could positively affect performance in the comprehension segment of the General Paper. In the forum postings, stance support moves were signalled in a sustained fashion through explicit indicators of intention to defend the writer’s position, as in these examples (in italics) from the posting reproduced in Fig. 3: Raising opposing view to be rebutted – Coming to the issue of . . . Indicating shift to rebuttal moves – But . . . Adding reasons to disprove opposing view – It’s not like . . . anyway . . . Also . . . In addition, the presence of cohesive ties between elaborative clauses, such as the recurrent expression of meanings relating to ‘‘cost’’ (underlined in Fig. 3), creates a consistent focus on the writer’s intention to rebut an opposing claim (too expensive) and thereby assert his own. At the same time, the cohesion device of employing words belonging to one area of semantic meaning (cost) enables the reader to see the relation between the rebuttal claims and the writer’s position. Explicit indication of intent to defend the writer’s own stance (in favour of more expensive aircraft) is further marked by a Stance Reiteration move at the end of the message (which . . . are a lot more capable . . . can perform many different roles . . .). Fig. 2. Excerpt from academic essay. A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 247 Fig. 3. Elaborated stance support in forum posting. In answer to the second question asked in this study (what support strategies are evident?), we may infer from Table 1 the following strategies: Citing authority; Using book knowledge as evidence or warrant for a claim; Appealing to the discourse community’s values; Projecting a hypothetical outcome to argue the benefit of one’s own position or the negative side of the opposing view; and Anticipating and countering an opposing view by questioning it or downplaying its significance. All these strategies were observed in the forum postings. All but the last two were found in the academic essay. Although opposing positions were not raised in Student L’s essay there was, as noted earlier, scope for anticipating and counter-arguing such positions. Topic knowledge from published sources featured in both forum postings and the academic essay, though the stance support motivation for the knowledge included was expressed with different degrees of explicitness in the two types of texts. In the forum postings, the rhetorical function of knowledge about fighter planes was easily discernable in nearly all instances. An example can be seen in Fig. 3 where Student J’s knowledge of the maintenance cost of different fighter planes (in Sentences 5–7) is employed to rebut the opposing view that the plane he favours is too expensive. Interviews with some of the ‘‘fighter plane’’ forum participants, including Student J, confirmed that they were avid readers of defence magazines such as Jane’s and Air International. As illustrated in Fig. 3, this stance support intention is readily apparent to the 248 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 Fig. 4. Use of book knowledge in academic essay. reader through framing signals of the writer’s goal to challenge an opposing view with a list of counter-arguments (But . . . Moreover . . . Also . . .), and through the cohesion chains of meaning centred around the topic of cost raised by the opposing view (cost, $ 1 billion, pay). A typical example of how topic knowledge is used in the academic essay can be seen in Fig. 4, extracted from a section entitled ‘‘The role of schema in reading comprehension.’’ To save space, only parts of key sentences from 5 of the 7 paragraphs in the section are reproduced below. According to Student L’s commentary on her essay, her goal was to validate her proposed investigation of the viability of teaching evaluative acts as a means of improving written answers in the GP reading comprehension paper. In her commentary on the ‘‘schema’’ section in Fig. 4, the intention to ‘‘validate’’ or ‘‘justify my area of research’’ was explicitly stated once and indirectly referred to three times. The intent to legitimize her proposed research was executed through the concluding sentence of Paragraph 5 (Fig. 4). The sentence, in full, appears in bold in Fig. 5 where more of Paragraph 5 is reproduced. Through the mention of ‘‘evaluative acts’’ and ‘‘interpreting the text’’ Student L appears to be signalling her intention to legitimize an assumption underlying her proposed research—the assumption that evaluative/interpretive acts are an integral part of the comprehension process. Her commentary made quite plain that she intended the legitimization of this assumption as justification for her proposal to investigate the effect of teaching evaluative acts as a means to better performance by General Paper students in the comprehension examination paper. Coming A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 249 Fig. 5. Use of book knowledge to justify writer’s position. towards the end of the ‘‘Schema Theory’’ section, the concluding sentence of Paragraph 5 was meant to indicate the supporting role of Student L’s knowledge on schema in arguing her macro claim about the value of teaching evaluative acts. It must be reiterated that the purpose of the above description of argument moves in the forum postings and academic essay is not to make comparative judgements about the writers or to imply a denigration of Student L’s writing ability. The purpose is to obtain a picture of the argument behaviours that students are capable of in peer-to-peer interaction and in a formal writing context. The findings show that the intention to support a stance was present in both the forum postings and the academic essay. The analysis of moves revealed that the forum participants’ discourse repertoires contain stance support moves that could be harnessed and developed for use in academic writing. Discussion This study of argument moves in online forum postings and in an academic essay was undertaken to throw light on the question of whether there are socially situated argument skills that may be relevant for the development of competence in academic writing. The findings reveal that stance assertion and stance support moves occur in both online postings and the academic essay, offering grounds for affirming suggestions made previously (Kramer-Dahl, 2005; Street, 1997) to value students’ out-of-school literacy practices in literacy classrooms. The range of argument moves found in the forum postings indicates that instruction in expository essay writing in secondary school could profitably start from the argument practices that students enact in peerto-peer interaction with the teacher building on those practices by demonstrating the modifications that must be made to adapt the stance support moves of informal argument for argument in academic essay writing. Furthermore, the occurrence of counter-argument moves and the rhetorical use of topic knowledge in the forum excerpts from students who had not undergone systematic training in expository writing challenges the deficit view of some Singapore teachers that secondary school students ‘‘can’t argue.’’ The reality may be closer to the view that most students have some ability in argument construction even if they have not been formally taught. The type and ordering of moves in the online forum postings (in Table 1) suggest that secondary students’ argumentation skills include the countering of opposing views and overt 250 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 rhetorical deployment of topic knowledge for stance support, skills needed in academic writing to generate considered, balanced arguments and demonstrate a student’s mastery of content knowledge. These skills do not appear to transfer naturally to academic writing tasks, considering Student L’s rather understated and indirect signalling of her intention to use topic knowledge from the literature to support her macro claim. The appearance of counter-argument moves in the forum postings and not in the essay seems to confirm Moss’ (2000) observation that ‘‘informal literacies do not act as a powerful resource within schooled settings (p. 62)’’. An alternative explanation may lie in the model of ‘‘achievement of precompetence’’ proposed by Austin, Dwyer’ and Freebody (2003, p. 69). The absence of counter-arguments and the indirect signaling of stance support may reflect Student L’s achievement of precompetence in expository writing, suggesting perhaps that explicit instruction is needed to enable students to capitalize on their ‘‘informal literacies’’ and move the student to the next level of writing competence. The fairly sophisticated argument moves in the forum postings suggest that more overtly signaled stance support moves can be activated during academic writing in a form aligned with the conventions of academic discourse if instruction is provided in academic writing courses. The possibility of developing informal argument skills for formal academic writing poses the question of how this can be achieved. Based on the argument moves observed in the texts analysed in this study and the manner of their realisation, two approaches to instruction seem necessary. The first is to guide students to the conceptualisation of a felt intention to persuade their reader to accept their position on the issue posed by the writing task so that they can use their rhetorical intention to manage the thinking and writer–reader interaction processes during writing. The second is to encourage a rhetorical-function approach to book knowledge so that student writers view knowledge critically for its potential use as ground or warrant for their own claims and not as ‘‘facts’’ to be recounted without comment. If students write with a sustained felt intention to argue their thesis, the intention would very likely influence choice of meaning and language at paragraph and sentence level to produce recurrent allusions to a consistent overall stance, thus observing the practice in English academic writing of pointing out ‘‘the main thesis . . . repeatedly, so as not to be missed’’ (Mauranen, 1993, as cited in Hyland, 2006, p. 150). The first step to writing with a felt rhetorical intention may be through group or individual exercises that channel students’ focal attention from content knowledge to the explicit and tacit demands of the writing task. Students might work in small groups to identify the required discourse acts implied in the wording of the essay question (e.g., to assert what kind of interpretive position about what issue) and the cultural (disciplinary) values operating in the knowledge community that determine the kinds of claims that can be made and the nature of evidence that is regarded as acceptable. When students pay deliberate attention to how they intend to respond to the demands of the writing assignment in terms of the stance they would take and the rhetorical moves they should make, their socially acquired argument skills are more likely to come into play with the possibility of enhancing their sensitivity to underelaborated or un-elaborated support claims and directing their thinking to the transforming of book knowledge to serve their rhetorical purpose. A strongly felt commitment to a position appears to be responsible for the skilful weaving of different types of support moves into convincing arguments in many of the forum postings, Fig. 3 being an example. The forum participants’ commitment to the position they expressed in their postings must have sprung from their avid interest in fighter planes, an interest confirmed in interviews. It may be inferred that there has to be some degree of active engagement with an issue before students can adopt the attitudinal posturing that enables them to step into the authorial role of ‘‘arguer and . . . evaluator’’ (Flottum, Dahl, & Kinn, 2006, p. 82) in expository writing. A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 251 Instruction in expository writing, especially at high school and college level, should perhaps include explicit teaching of the cognitive and writer–reader interaction processes for sustaining visibility of the macro claim in the writer’s position throughout a text so that students can, to borrow a phrase from Lillis (2006), ‘‘populate their text with their own intention’’ (p. 40). One method of explicit teaching, known in genre-based pedagogy as deconstruction (e.g., Veel, 2006), is teacher-guided observation of stance taking and stance support moves in well written expository essays. But deconstruction of expert writers’ argument moves may be insufficient if students view argument acts as esoteric classroom knowledge far removed from their discourse experience. To bridge the gap between socially acquired informal argument practices and school-based expository writing, deconstruction of well formed written arguments might be accompanied by demonstration of stance support moves taken from transcripts of students’ informal arguments in online discussion or class debates. A graphic account of the moves and move organisation they are capable of (like those in Fig. 3) could raise students’ confidence in their argument-construction skills and encourage them to transfer to academic writing the same felt intention to persuade an audience that impels their argument moves in peerto-peer interaction. It must be acknowledged that stance assertion and support moves in academic writing are realised differently from the same moves in friendly, everyday argument. The objective of showing students their informal acts of argumentation is not to suggest that these acts can be transplanted without modification to formal writing but to build students’ self confidence in their existing argument practices and their ability to adopt the attitudinal posturing of ‘‘arguer.’’ Having convinced students that they are capable of the stance assertion and stance support moves of argument, the writing teacher can proceed in subsequent lessons to show them how these moves are typically enacted and organised in expository writing in disciplinary contexts relevant to the class. One of the earliest lessons in the writing course may have to help students to distinguish between stances that are personal points of view (such as those expressed in a forum discussion) and positions that are legitimized by the values and practices of the disciplinary community. Explicit instruction could demonstrate how the culture of a discipline may require students to qualify and hedge thesis and support claims so as to project the persona of cautious, objective scholar. Students of non-native English speaking backgrounds would also need lessons to practise the linguistic structures for realising qualification and hedging. In addition, most students (like Student L, the writer of the essay featured in this paper) are likely to benefit from explicit instruction in the judicious selection and rhetorical use of knowledge from published sources to serve as ground and warrant for claims. Lessons on the rhetorical use of knowledge may be more effective if they include the linguistic forms for overtly signalling the argument role of cited knowledge, its relevance to the student writer’s thesis, and the student’s evaluative or interpretive comment, because form and discourse function are inextricably linked. Notwithstanding Moss’ (2000) observation that ‘‘informal literacies do not act as a powerful resource within schooled settings’’ (p. 62), bringing students’ informal argument practices into the writing class could contribute to the development of those practices into competencies for expository writing for academic purposes if instruction explicitly targets the transformation and adaptation of informal discourse behaviours for academic contexts. The naturalness with which the forum participants used their knowledge of fighter planes to argue their position suggests the viability of encouraging a rhetorical-function approach to topic knowledge, the second pedagogical approach advocated in this section. The fact that the writing of academic expository essays is often situated in the context of student assessment in content courses seems to channel students’ focal attention to book knowledge in the subject and the 252 A. Chandrasegaran / Journal of Second Language Writing 17 (2008) 237–254 accurate re-statement of that knowledge at the cost of attention to the interpersonal dimension of achieving argument goals. Given the fact that ‘‘often the knowledge available is not in the form required for the communicative demands’’ (Kucer, 2005), an overwhelming preoccupation with topic knowledge probably accounts for the low level incidence of knowledge synthesizing that Folman and Connor (2005) have observed in students’ essays—an observation that could be justifiably made of sections in Student L’s essay. Knowledge synthesis is the result of selecting and re-organising items of knowledge for a communicative goal, creating links between knowledge items not explicitly linked in the original source, and deciding what aspects to foreground and background—all cognitive procedures subsumed in the process referred to by Bereiter and Scardamalia (1987) as knowledge transforming. As attitude to knowledge has been recognised as a constraint on the quality of the argument (Santos & Santos, 1999), instruction in knowledge transforming processes could nudge students towards an attitudinal approach to book knowledge that sees knowledge as propositions to be manipulated for rhetorical purposes in their own writing, rather than as ‘‘facts’’ for accurate reproduction. Explicit instruction in knowledge transforming might take the form of practice exercises in reorganising knowledge to fit given rhetorical goals and activities that develop the mental posturing appropriate for the writer’s role of arguer in the context of the disciplinary course for which the writing task is set. Practice exercises could involve small groups of students working collaboratively on evaluating the relevance of information in excerpts from the course reading and then re-organising selected relevant information to serve a given rhetorical goal (e.g., to provide grounds for a given thesis claim or to serve as warrant to back a support claim). Conscious attempts at deploying knowledge for a rhetorical purpose could result in students engaging more with the ideas they encounter in sources and could engender a depth of knowledge that is likely to enhance the quality of their arguments to the extent that merely ‘‘ventriloquating’’ (Lillis, 2006, p. 41) book knowledge would not. Conclusion This study of students’ argument practices in two different contexts has shown that student writers engage in stance taking and stance support moves in both online forum postings and the academic essay. The manner in which stance support is enacted in the forum postings indicates that capabilities in countering anticipated opposing views and the deployment of topic knowledge to serve argument goals exist in the informal discourse repertoire of secondary school students. The presence of these capabilities suggests their potential for development, through explicit instruction, into competencies for expository writing for academic purposes. These conclusions about students’ argumentation abilities and the pedagogical implications derived from them must be offered with a degree of tentativeness, since the study observed only two cases—one post-graduate student’s essay and the forum postings of three secondary students on one thread of discussion. Still, each observation case can be regarded as ‘‘a concrete realisation of a possibility that exists at the collective level (population)’’ (Ercikan & Roth, 2006, p. 15). The possibility that exists, indicated by the observations reported in the findings section, is that students have socially acquired skills of stance support that can, with the right instruction, be developed for academic essay writing. Further research is needed to confirm if, impelled by a felt social intention to justify a personal position, students would produce a complex organisation of argument moves similar to those seen in the forum postings in this study. In addition, research in pedagogical methods might test the efficacy of techniques of explicit instruction aimed at raising A.
