Conversational Topic Discontinuity Markers in Taiwanese EFL Classrooms Ming-Chu Liao (廖明珠) Dr. David S. D. Tseng (曾守得) Abstract As cited by previous sociolinguistic researchers, the phenomenon of topic continuity in speech has received significant attention. Scant research has focused on what, how, and why discontinuity occurs. This study explores the four most frequently identified markers (pause, repair, overlap, and interruption) in Taiwanese senior high school English classrooms, three of which had observations conducted in them: one all-male, one all-female, and one co-ed, respectively. Subsequent retrospective interview protocols were administered in order to elicit information from teachers concerning their perspectives on the observed data. Results of the 21 sessions revealed divergent distribution of the four discontinuity markers for all-male and all-female classes. Culture and gender had a significant impact on the highest and lowest incidences of classroom conversational topic discontinuity. Additionally, teachers reported their perceptions of the reasons which led to the four markers influencing occurrence of topic discontinuity. At the end of this paper the author discusses educational implications and suggestions for further study. The findings may shed some light on the management of turn-taking and topic maintenance in the classroom for EFL teacher training. Keywords: sociolinguistic, topic continuity, topic discontinuity marker, classroom observation, retrospective interview protocol 1 Social functions play a vital role in the conversation interaction management of language, with society and language being closely intertwined. Interaction in EFL classrooms is initiated either by the teacher or students to make their topic continue or discontinue, with the management of conversational topics playing an essential role. It is critical to explore which discontinuity markers proved decisive in conversational topics. Tsao (1979, 1988, 1990) suggested that as far as basic conversational topics are concerned, a “topic chain” is a basic unit. It might take the form of a combination of naturally flowing sentences where the noun in the first sentence represents the topic of conversation. Chafe (1994) treated a discourse topic as an idea unit that can only reside in the speaker's peripheral or semi-active consciousness. Chui (2003) suggested that a topic is introduced by a logical sequence of sentence clauses relating to the same subject. Topics then come together with other topics, showing semantic connection to complete a chain, which exhibits a common theme in each related topic, whose boundaries are set by significant variation of time, place, character or event. Numerous studies have dealt with conversational topics (Button & Casey,1985; Foppa, 1990; Heyman, 1986; Maynard & Zimmerman, 1984; Tannen, 1989). Coulthard (1985) examined distribution of single features of interaction, such as topic control and topic discontinuity markers in addition to variant combination of features. Among these studies, the most important element of conversational language has been topic development. In addition, these studies have noted the importance of two components in topic development: “progression” and “maintenance” (Bergmann, 1990). Topic progression tends to ensure topic flow by demanding contribution to the interaction. Topic maintenance assists coherence of the unfolding discourse ensuring that speakers remain on a topic. Typically, the natural linkage between an utterance and the second speaker’s contribution to the conversation contributes to topic development when new material is introduced to the subject under discussion, sustaining discourse. In order to maintain this development, each speaker must individually and simultaneously assess whether a given sequence of utterances form a logically connected text. Yet speakers are not limited to this developmental pattern. Having acquired a turn, the participant may determine direction of the conversation by developing the same topic, changing to another topic, or reallocating a speaking turn to an alternative party (Ng & Bradac, 1993). That is, speakers change topics with recognizable boundaries, resulting in topic discontinuity (Chafe, 1987; van Dijk, 1981; van Dijk and Kintsch, 1983). Earlier research found discontinuity markers affecting conversational turn-taking (Chui, 2001; Schiffrin, 1987; van Dijk and Kintsch, 1983; West & Zimmerman, 1983). Pausing and repair are used in the main to recover the discourse where it has become inactive through a conversational impasse within the boundaries of a paragraph theme 2 (Givon, 1993). More substantial or frequent pauses become more common following a change of subject (Chui, 2001), with particular significance in speech production: e.g., pause before a less predictable word signifies difficulty in lexical access. Alternatively, Shei (2005) noted that in a Chinese speaker’s retrospection, pause is a highly unlikely feature before Chinese sentence final particles (SFP). In addition, Fox, Hayashi & Jasperson (1996) stated that English repair is based upon traditional syntax, where the repairing segment does not recycle back to the verb if repair is initiated post-verbally for syntactic constraint. The extent of an English cycle further depends upon whether the repair is initiated at the outset of a turn. Repair is typically occasioned by problems of understanding. Levelt (1983) defined repair as organized ways of dealing with various kinds of trouble in interaction’s progress, such as mishearing or misunderstanding. He has further clarified that repair phenomena do not form regular parts of talk-in-interaction. Tseng (2006) explored the organization of repair in Chinese conversation and found that repairs tend to recycle only the word immediately prior to the repair source, regardless of its category. If the preceding word is part of a complex noun phrase, recycling is blocked and quantity tends toward essential versus lexical-form complexity. Its significance becomes more apparent when a speaker attempts to resume the conversation as soon as possible and maintain the process. Zelinsky-Wibbelt (2003) defined both overlap and interruption as means used to discontinue a topic and take command of the speaking turn. Overlap occurs during instances of slight over-anticipation by the next speaker. Instead of beginning to speak immediately following the current speaker’s turn, the next speaker begins to speak at the very end of a current speaker’s turn, overlapping the last word or last part of his or her utterance. In other instances, interruption is traditionally associated with violation of conversational rules, and an attempt to dominate interaction via control of the floor and topic of conversation. Here the next speaker begins at some point in the current speaker’s turn, unidentifiable as a last word. With discourse topics hierarchically and non-linearly organized, one conversational topic can be disrupted by another, which in turn continues or discontinues (Waltereit, 2002). Numerous previous studies explored factors related to continuity within topics in daily conversations (Amfo, 2001; Andersen, 1998; Foster, 1983; Givón, 1983, 1993), yet few examined what gave rise to discontinuity (Chui, 2002; Reboul & Moeschler, 1997), not to mention discontinuity markers in classroom settings. Discourse in daily dialog differs from that in a classroom setting; the latter is topic-based (Coulthard, 1985; Foster, 1986; Martinez-Marquez, 1989) with highly structured turn-taking interaction patterns between teachers and learners (Chen, 1983). Among discontinuity markers observed previously, pause, repair, overlap and interruption were most frequently and directly identified in EFL context (Chui, 2000, 2001; Liu, & Chang, 3 2005). Results of this research would have provided more insight had they addressed language use in an EFL classroom setting. Generally speaking, senior high schools contain three types of classes: all-male, all-female, and co-ed. This study explores the conversational discontinuity markers in each type of class, addressing the following research questions: (a) What are the frequency respective distribution differences among the four topic discontinuity markers in EFL senior high classrooms? (b) How do classes differ in frequency distribution among the discontinuity markers? (c) How do teachers’ perceptions differ from actual performance in class? METHOD School Settings The three senior high schools chosen in this study are located in Taiwan and identified as Schools A (all-male), B (all-female), and C (co-ed). Teacher Participants One female English teacher was selected from each school; she and her class of senior high school students took part in this study. Teachers were non-native English speakers and averaged 28 years of age. Each held a masters’ degree from a normal university and averaged 2.7 years of teaching experience. Student Participants The three classes were all 10th grade classes and taught by Teacher A, B and C respectively. They were one all-male class, one all-female class, and one co-ed class and identified as Class A, Class B, and Class C respectively. The number of students in Classes A to C was 47, 48 and 48 respectively. Based upon their scores on simulated GEPT elementary tests and on senior high school entrance examination English tests, the students in the three classes were found to be homogenous in English proficiency levels (t = .499, p = .621). Instruments Classroom Observation Each teacher was observed for one lesson unit for one class for between five and eight sessions. One unit covers sections of vocabulary and phrases, reading passages, supplementary materials, and test explanation. The focus of study was not revealed to the observed teachers and students to exclude researcher-respondent interaction. A total of 21 sessions, each 50 minutes long, in these classes were videotaped and observed with notes by the researcher herself. All utterances were transcribed verbatim in the very language used by the observed teachers and students for advanced analysis. 4 Retrospective Interview Protocol After each teacher’s observation was completed, an interview was conducted with the three teachers respectively. The interview was designed to elicit teachers’ verbal reports of their perceptions of occurrences of topic discontinuity. Interviews were videotaped and transcribed verbatim for further analysis. Data Analysis Generally, analysis of qualitative data proceeded in four steps: coding, categorizing, description and interpretation. Based on structuring of topic chains, transcripts were first categorized in terms of linguistic manifestation of discontinuity and interruptions. Topic discontinuity was subcategorized into pausing and repair (Chui, 2002), the interruptions as in-turn or marginal. Coding System Topic discontinuity can be categorized according to the coding schemes below. Based mainly on a number of previous studies, the researcher modified and combined the categories below with examples extracted from the transcription. 1. Pausing: Common feature of natural speech in which gaps or hesitations appear during production of utterances. Pause can be subcategorized as empty or filled (Richard, Platt & Platt, 1998; Chui, 2001). (a) Empty pauses refer to pausing without filled gaps in speech. S: I have the so-called periodical. T: Really? <P > What is a periodical? S: More professional? T: More professional, right. (b) Filled pauses refer to pausing with non-lexical utterances like uh, hmm, um, eh, and lexical utterances such as na for “and”, zhege for “this”, nage for “that”, ranhou for “then”, and jiushi for “that is”, etc. T: … “can not” is used for expressing strong doubt. <Then> why do you suspect strongly? <That is > he is sure that it should be male. You have to infer this way. <Then > what about number 2? S: The answer is B. 2. Repair: Ways in which errors, unintended form, or misunderstanding are corrected by speakers or others during conversation (Richards, Platt, & Platt, 1998). In discourse analysis, the organization of repair can normally be divided into self- and other-repair. (a) Self repair refers to that self-initiated by the speaker in conversation. T: Those specialists will help you spend more money. Help you spend money, Yeah, Isn’t it ironic?...Do you see ironic? Right, so ironic, yes? 5 S: Ha, ha! (b) Other repair refers to a repair made by other speaker(s) in conversation. T: Did you find it? As you go out to the counter, the items were put there. Wow, only ten dollars, so cheap. Everything for 10 dollars, be it candy or chocolate on the checking counter, and they cost just 10 dollars. [ ] S: That refers to when you pay at the counter of the 7-11, the little bamboo baskets on the counter holding the items, Yes? You can’t help buying them, can you? 3. Overlap: A phenomenon which occurs when two persons talk simultaneously at a turn transition relevance point where both speakers have the right to complete their respective utterances (Sacks, Schegloff & Jefferson, 1974; Lerner, 1989; Rod & Ilana, 2008). Biq (1998) categorized these as: incomplete and complete. (a) Complete overlaps occur when both utterances are completed with neither speakers withdrawing or with both speakers withdrawing. S: Teacher, isn’t the registration fee NT$1,100? T: That’s right. The more advanced the level of the test, the more expensive the fee. Because the number of test takers decreases for advanced levels, while the personnel expenditure for marking the tests remains the same. What can they do? Clearly, they have to charge higher and higher rates for the advanced levels. (b) Incomplete overlaps occur when one speaker insists on the completion of the turn leading to the other speakers’ withdrawal. T: …..but he is very smart, so we choose “although”, Option B. Why isn’t it A? It says that he can get average scores because he is very clever, but it doesn’t make sense. O.K., next one… S: Participle construction is so difficult … T: Participle construction? Oh, what should be the underlying form of it? 4. Interruption: The phenomenon occurs when a second speaker usurps another speaker’s right to continue by taking the conversational floor in the absence of any evidence that the other speaker intended to relinquish the turn (Bennett, 1981): i.e., projected to begin in the middle of a point in conversation that is in no way a possible completion point for a turn. Based on Li (2006), interruptions can be classified as controlling and non-controlling. (a) Controlling interruption means when the interrupted speaker withdraws and the interrupting speaker completes the turn. T: Because it said shoppers will spend an extra dollar each minute, one additional dollar for each additional minute. Therefore, you would spend 6 30 extra dollars in 30 minutes. Probably more than that, I would guess. Like me, for example, I could sit down for a cup of coffee if I am tired, and glance at a beautiful dress tagged NT$1,200, then I… [ ] S: One minute for NT$1,200! Maybe more money! T: Am I that easily influenced? S: Yes, any piece of clothing sold in a department store starts at NT$1,000! (b) Non-controlling interruption refers to the situation where the interrupted speakers’ turn is not withdrawn. S: But how could you buy it since it’s so expensive? T: But I don’t find it expensive! S: Won’t your husband scold you for that? You … [ ] T: I can control myself; I have bought only two items of clothing in one month! S: Aha…your husband will be angry! RESULTS AND DISCUSSION Classroom Observation Results The information obtained from the classroom observations will be presented first, followed by interview data. Table 1 presents total instances of topic discontinuity for each class. Combined with results of the three classes, a total of 18,042 occurrences concerning topic discontinuity were identified. Pauses represented a plurality (8550), followed by interruptions (3566) and repairs (3317). Repair had the lowest frequency (2609). For total occurrences, Class A presents the greatest frequency of distribution, Class C next, Class B the least. There are two possible explanations for the findings. First, similar to results yielded by daily conversation (Chui, 2002), topic discontinuity occurred frequently in the EFL senior high school classrooms. Second, contrary to the common assumption that teacher authority dominates the conversation completely in class students were often involved in the four markers causing discontinuity. Table 1 Pause Repair Overall Occurrences of the TDMs in the Three Classes Class A (6 sessions) Class B (8 sessions) Class C (7 sessions) Total (21 sessions) 3526 (48.77%) 2174 (45.32%) 2850 (47.38%) 8550 (47.39%) 1 1194 (16.51%) 1017 (21.20%) 1106 (18.39%) 3317 (18.38%) 3 7 Rank Overlap 1067 (14.76%) Interruption 1443 (19.96%) Total 7230 672 870 2609 (14.01%) 934 (19.47%) 4797 (14.46%) 1189 (19.77%) 6015 (14.46%) 3566 (19.76%) 18042 4 2 Table 2 shows frequency distribution of markers for each class divided by the total number of observed sessions, since these differ among classes. Frequency of the four markers display similar distributions across classes: pause with the highest, followed by interruption, repair, and overlap. This indicates pause as the most prevalent marker in EFL senior classrooms, which corresponds to Oliveira’s (2002) claim that pausing is used frequently for emphasis in pedagogical situations. Table 2 Average Frequency Distributions of the TDMs in the Three Classes Class A Class B Class C Total Pause Repair Overlap Interruption 271.8 199.0 177.8 587.7 127.1 84.0 407.1 158.0 124.3 1266.6 484.1 386.1 240.5 116.8 169.9 527.1 Total 1205.0 599.6 859.3 2663.9 Differences across the topic discontinuity markers were further analyzed (Table 3). Only Classes A and B proved statistically significant in the four categories, while Classes A and C as well as B and C showed no statistical significance at all. Moreover, the post hoc test showed Class A outscoring Class B in frequency of distribution. As for differences between classes, these could be attributed to students’ gender differences. With the prevalence of communicative competence, recent studies have revealed male and female speakers presenting noticeable differences in discourse (Coates, 1993; 1996; Farris, 1998; Goddard & Mean, 2000). This study’s three teachers were female, while the three classes were all-male, all-female, and co-ed, respectively. This may explain why only Class A and Class B displayed statistically significant differences. Data collected and analyzed in this study supported previous findings. Cameron & Coates’ (1987) research on significant connection between speaker sex and pausing, found that women tended to pause more often, explained by the fact that they allow for topic discontinuance by pausing, while men do not. A female teacher in the all-female Class B would clearly give rise to an increase in the occurrence of pauses. In addition, Juliane and Andrea (2003) noted a key aspect of conversational analytic work on repair: ‘to show how repair illustrates participants’ orientations towards the 8 basic turn-taking rules’. By extending this suggestion, it seems reasonable to infer that repair involving gender trouble may show participants’ orientations toward stereotypical understanding of gender. The findings in relation to interruptions align with previous research, which pointed out that males tend to interrupt in conversation and alter the topic of other speakers (Deuchar, 1987; Karakowsy, McBey & Miller, 2004). More often than not, male speakers would like to control the topic and dominate interaction, such that men interrupted women much more than vice versa. Results of this study also conform to previous research which showed that males produced more repairs in speech (Pica, Holliday, Lewis, Berducci & et al, 1991; Sunderland, 2000, 2002; Swann & Graddol, 1995).

Class A is the only one in which empty and filled pauses manifested a statistically significant difference; others showed no such difference in either subcategory. There may be two possible explanations for this. The range of empty pauses is as wide as it is long as a speaker stops for a moment or longer up to 10 seconds (Chui, 2002), meaning that frequency distribution would accumulate more. Class A consisted of all male students, who tended to yield comparatively more empty pauses, and this result coincides with Butterworth (1980) and Rosenfield (1987).

Class B demonstrated significant differences in self- and other-repair; neither of the other classes did. These results can again be attributed to gender-related factors. In terms of a sociolinguistic perspective, females were found to be more eager to produce self-repair in interaction: they express thoughtful concern and have harmonious relationships with other speakers. Thus gender was considered a dominating factor in most self repairs (West & Garcia, 1988). With the female teacher and all-female students, the self repair utterances were significantly reinforced (Kasper, 1985).

Table 8 depicts overlap subcategories of frequency distribution between classes. Findings indicate that Class A’s performance was statistically significantly different in terms of complete and incomplete overlap. Classes B and C showed no significant difference. A possible explanation might be the feature of an all-male class. Male students tend to insist on a topic they initiate while the female teacher is speaking, thus more complete overlap emerged (Itakura & Tsui, 2004).

As in the previous section, Class A demonstrated a statistically significant difference in the (non-)controlling interruptions; Classes B and C had no such difference. Observed data indicated male students cutting in female teachers’ speech with high frequency, in addition to tending to hold the conversation topic and manage to alter the teachers’ topic to theirs. They tend to interrupt with their desired topic and make a teacher cooperate, which corresponds to studies of Woods (1988) and Zimmerman & West (1975).

First of all, as to factors making topics discontinue, all attributed these to repair. They reported, in common with one another, that repairs occurred most and pause least frequently in their class. Still, data gleaned from classroom observation showed a diametric opposite of teachers’ perceptions. In fact, observed production of pauses pre-dominated the other markers in causing discontinuity, while repair was comparatively less frequent. Based on the clipped classroom observation information, each teacher participant then reported retrospectively on the reasons why they performed two subcategories of each four markers. Synthesizing their interview results, they regarded occurrence of empty pauses causing topic discontinuity mostly when they were used either to take a short break in a lecture or when waiting for replay of questions raised by the teacher. 11 Filled pauses occurred to cause topic discontinuity mostly when used to ensure that students understood a teacher’s instructions and draw their attention to focal points they emphasized. As for self-repair that made a topic discontinue, teachers reported that a large majority of occurrences were intended to explain, exemplify, and even expand the teaching materials. Other repair involved more students who tended to ask questions and made proposals, which would break the topic continuity. When it comes to both complete and incomplete overlaps in topic discontinuity, the teachers identified that they occurred in similar situations. They attempted to please a teacher by showing they were focusing attentively on what a teacher instructed. Students tend to relate what a teacher says, to something unique or unexpected. Lastly, controlling interruption that results in discontinuity was identified in three circumstances, all due to disagreement of the topic content. Teachers cut in the students’ speech, the students interrupt the teachers’ speech, and the students interrupt the other students. Non-controlling interruption was performed to allow new information flow between speakers other than the original topic; thus topic continuity would be impaired. CONCLUSION Among the markers, pauses occurred most frequently, followed by interruption, overlap and repair. As for subcategories of markers, the most frequent were empty pauses, with non-controlling interruption second in the all-male class. The all-female class used empty pauses most frequently, followed by filled pauses. Female teachers’ discourse with female students led to more pauses than their discourse with males, because females allow for topic discontinuance by pausing. The all-female class tended to avoid interrupting female teachers in the classroom. Topics for females typically involve developing trust and some form of connection with conversational partners (e.g., Itakura, 2001; Tannen, 1990). Such characteristics generally make them more responsive and considerate listeners than male conversationalists (e.g., Maltz & Borker, 1982; Magolda, 1989). By contrast, male students tended to interrupt the female teachers, displaying a desire to control topic and dominate interaction. Conversation is more often used by male speakers to ascertain status or to acquire/deliver information (e.g., Case, 1995; Nordenstam, 1992). Such patterns of conversational behavior have been observed among men trying to dominate, direct, or control conversations with women in public (e.g., Holmes, 1995). In addition, teachers thought repairs occurred most often and that pauses were the least frequently occurring mechanism in terms of topic discontinuity. In fact, there is a stark contrast between actual performance in the classroom and their perceptions. All in all, the gender- and culture-related issues revealed that the study provided significant findings on topic discontinuity between female teachers and all-male, all-female, and co-ed 12 classes. Educational Implications Traditionally, EFL senior high school teachers were supposed to wield absolute authority, especially in flow of speech. The findings of this study highlight the importance of improved command of classroom speech based upon causes of the conversational topic discontinuity. They may well choose to increase interaction, thus discontinuity markers will inevitably occur to activate the atmosphere and encourage participation. On the contrary, if they intend to develop their instructional purpose, they have to maintain control of topics to avoid discontinuity makers from students to distract or postpone the conversational schedule. It is thus difficult to strike a balance between focus on smooth lecture, in which teachers usually dominate the topic, and effective practice, which involves communicative activities between teachers and students and/or between students. Consequently, based on the findings of this study, classroom practice focusing on the importance and effectiveness of skills and ability to control turn-taking, topic dominance, interaction modes, etc. should be a primary concern for EFL teacher training (e.g., Palmer, 1989; Wei, 1996). EFL teachers are expected to be aware of topic shift and handle it carefully, managing topic continuity and discontinuity to boost instructional effect, classroom atmosphere, and communication. In light of the findings of culture and gender-related tendency or preference, course design and curriculum development should incorporate the understanding of diverse attitudes and strategies when teachers of different genders face students of both sexes. In this way, the teaching and learning effect in classrooms can be facilitated and reinforced. Suggestions for Further Studies This study is limited to the gender distribution of teachers. With far fewer male teachers at the senior high school stage, this practical difficulty results from a lack of appropriate male teachers. The practical difficulty in finding three male English teachers is not uncommon because English teachers in secondary education are overwhelming female in the EFL context, especially in Eastern Asian countries. Future studies should attempt to overcome this barrier and implement research involving male teachers with similar backgrounds to the all-male, all-female, and co-ed classes. Then the results can be analyzed in contrast with the female teachers to aforementioned three types of classes. In this way, more phenomena regarding the role of gender difference in the discontinuity in the EFL classrooms could be identified. REFERENCES 13 Andersen, G. (1998).
