The Australian Journal oj Education, Vol. 25, No.2, 1981 A Study of Teacher Epistemologies! R. E. YOUNG Teachers' views of knowledge, their epistemologies, are likely to affect the way they organize and transmit information in the classroom. After ethnographic study had revealed that teachers' epistemologies varied greatly in their degree of formalization, a theory of the practical implications of teacher epistemologies was developed based on Basil Bernstein's account of visible and invisible pedagogies. Epistemology and curriculum code, assessment approach and control ideology were operationalized in four Likert scales. A survey was conducted and analysis of the data lent strong support both to the Bernstein theory and its extension to include the role played by epistemology. The views teachers may have concerning the nature of knowledge and the methods of obtaining it are of clear importance for any adequate understanding of teaching. 2 This importance has been underscored by recent developments in the sociology of teaching and curriculum (e.g. Young, 1971; Musgrave, 1974; 1978) as epitomized by Michael Young's 1971 statement of the perspective adopted by the contributors to his volume Knowledge and Control: They do not take for granted existing definitions of educational reality ... they are inevitably led to consider . . . 'What counts as educational knowledge' as problematic. The implication of this is that one major focus of the sociology of education becomes an inquiry into the social organization of knowledge in educational institutions. (p. 3) Historical studies in the curriculum have revealed the crucial role played by conceptions of knowledge in the process of the social organization and distribution of knowledge (Layton, 1974; Musgrave, 1974; McCann, 1977). The debate between proponents of 'open' and 'traditional' education (whatever those terms may mean) has also been characterized by the crucial importance placed on epistemological issues (Petrie, 1975; Morgan, 1976; Nyberg, 1975). Until recently, however, there has been little attempt to study teachers' conceptions of knowledge systematically and empirically. Those few attempts which have been made have been marked by a virtual absence of theory, by the complete absence of ethnographic work to establish the nature of teachers' views about knowledge, and by inadequate and clearly faulty research design and/or measurement techniques. The first type of research which we will examine might be labelled the 'philosophical' tradition, studies in this tradition attempt to test philosophical 'theories' about teacher epistemologies. Typically they identify four major types of ideology by means of 'conceptual' analysis: realism, idealism, pragmatism and existentialism. Items are then written to construct checklists such as the 194 Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 195 Ross Epistemology Inventory (Ross, 1970) and the instruments are administered to teachers to see if their epistemological beliefs are consistent with other educational beliefs, measured by similar instruments (e.g. Abbas, 1949; Erlich, 1963; Tesconi, 1965; Thomas, 1968; Ross, 1970; Smith, 1971; Starkey and Barr, 1972). A common finding is that the degree of consistency in teachers' epistemologies is low; they typically select items from checklists which represent several of the four different types of epistemology. The pattern of correlations which results is difficult to interpret and there appears to be only a limited relationship between 'epistemologies' measured in this way and other areas of teachers' philosophy. An alternative explanation for the pattern of findings is that the categories used in instrument construction are not very useful categories for describing teacher epistemologies, and that there are other differences between teachers about epistemological questions which might be more important than those identified by conceptual analysis of philosophical viewpoints. The implicit assumption of most of this research, of a simple congruence between one set of beliefs and another, or between beliefs and actions, does not advance our understanding of the complex situated nature of the relationship between beliefs and behaviour. An approach of this kind also ignores several decades of research into the relationship between attitudes and actions. When one steps outside the 'philosophical' tradition of research just discussed, only a few isolated empirical studies remain. Silvan Tomkins (1962; 1965), a psychologist, included a number of epistemological items in a 57-item scale for measuring what he believed to be basic polar orientations in western thought. Basing his item content on the history of ideas, he created items to measure beliefs about mathematics, philosophy of science, metaphysics, epistemology, political ideology, jurisprudence, and art. While Tomkins's results, which showed a weak but consistent pattern in answers to items, are suggestive of the possible existence of global ideological preferences or styles, the level of generality of the items and their method of derivation does not allow us to rule out the alternative hypothesis that the weak pattern of correlations found may be an artefact of respondents' capacities to adopt a response set due to a recognition of indexical cues in the item content. A more systematic attempt to produce a theory and measure of epistemological style was made by Royce (1959; 1964). After interviews, Royce identified, by 'impressionistic' interpretation, four distinct epistemological emphases: 'rationalism-thinking', 'empiricism-sensing', 'intuitionism-feeling', 'authoritarianism-believing'. Thus Royce's work was at least based on an attempt to discover the epistemological beliefs which respondents actually possess. However, the four postulated ways of approaching reality were not found to be distinct and separate emphases. Royce had his students and experts write items reflecting these four ways. The items were then presented to samples of respondents in a Likert format. Respondents, as in earlier 'philosophical' research, tended to display a mixed response. Again, in the procrustean style of previous research, Royce switched to a rank order method in which respondents were forced to assign statements to o~e of four ranks rather than question the appropriateness and mutual exclusiveness of his categories. Downloaded from aed.sagepub.com at Monash University on June 16, 2015 196 AustralianJournal of Education A weak scale was produced, but in the process the 'authoritarianism' dimension was dropped. Studies of the scale construct validity and reliability were not encouraging (jones, 1963). There was no room in the scale for respondents to adopt a mixed view, such as 'logical-empiricism', a view which many writers such as Radnitsky believe to be characteristic of much of western thought (Radnitsky, 1969;~Schutz, 1973, pp. 229-50; Habermas, 1974). For instance, under a forced ranking system, a response in which Rank 1 was given to 'Rationalism', 2 to 'Empiricism' and 3 to 'Intuitionism', etc. could represent a view of knowledge in which both rationality and empirical evidence were considered to be very important and in which intuition was seen to be much less important. The development of an adequate 'technique' for identifying particular epistemologies would appear to require a more careful study of the nature of the epistemological beliefs, values and attitudes of the group concerned. Similarly, the development of a useful theory of the role of different epistemologies would appear to be likely to be facilitated if an ethnographic exploration of these epistemologies were undertaken prior to further theory development. RESEARCH STRATEGY AND ETHNOGRAPHIC FINDINGS The research strategy adopted in the present study was a multi-stage approach in which decisions concerning each subsequent stage of the research were dependent upon the results of the previous stage. An initial ethnographic stage of the research aimed to identify and describe teachers' epistemologies; this was to be followed by theory building; then, in the light of theory and the ethnographic findings, a decision was to be made about an appropriate method for testing some of the central hypotheses of the theory. First, it is necessary to ensure that the ethnographic data upon which theory development is to be based are sufficiently representative to ensure that no perspective held by a significant minority of the target population is overlooked. Second, the data must be generated in sufficient depth to ensure that errors which arise from shallow interpretation, from the contexts in which any one body of data is gathered, and from failure to exhaust participant category systems, are avoided. Randomly chosen sub-samples of the staff of five secondary schools, each of which represented a different type of school (boys, girls, technical, 'comprehensive', government, private, etc.) were split into two random halves. Quotas were also balanced for science and maths teachers as against others, since a preliminary review of the literature suggested that this difference could be relevant. With the first half of the sample, semantic taxonomy interviews were conducted. The semantic taxonomy interview, a technique borrowed from cognitive anthropology, is a non-directive interview technique in which structural and attribute questions are asked about categories provided not by the researcher but by the respondent (Spradley and McCurdie, 1972). With the second half of the sample, a series of written paragraphs on broad epistemological questions was collected and respondents were asked to carry out a classification task involving the free grouping of 14 subject names Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 197 (physics, woodwork, ethics, psychology, music, etc.) representing the major domains of subject type along most of the available common-sense dimensions of classification (e.g. manual/non-manual, scientific/artistic, dealing with things/dealing with people, etc.). In addition, general ethnographic work was carried out over a period of three months, with classroom observation, corridor 'interviews' and group discussion, mainly to provide a general background to assist in the valid interpretation of data more systematically gathered. The result of extensive analysis of teachers' epistemic vocabulary, category systems, classification behaviour and general discussion in groups, and the mutual support found between separate bodies of data, indicated that a single major issue dominated teachers' consciousness and divided teachers' views. Teachers either accepted a logical/empiricist view of the physical sciences as an epitome of knowledge, or adopted a view which gave epistemic priority to more 'subjective', 'intuitive' or 'personal' ways of knowing (called here 'hermeneutic'), or, in the case of a small minority, adopted a dualistic system in which both types were recognized, called here the 'forms of knowledge' approach because of its resemblance to the view of Hirst (1965). About 10 per cent of teachers expressed views of knowledge which were irreconcilable with this basic typology. 3 It was found that the major differences between'teachers in the way they talked and wrote about knowledge could be described using a model of rules for describing symbolic systems in which there were rules for defining the boundaries of entities, rules for articulating entities, rules for the permitted mode(s) of epistemically valid reference to experience, and rules concerning the accent of objectivity or doubt attributed to symbolic systems which met the criterial rules just mentioned (Young, 1978). For instance, a logical/empirical view of science stresses the value of precise and clear entities, defined through some form of semantic empiricism, articulated by logical or mathematical rules and related to experience by sensory observation, providing a symbolic system regarded as objective, even if possibly incomplete or subject to change if better data become available (Young, 1979). This finding was consistent with one of the main currents of sociological thought about epistemologies in society; both Durkheim (1977) and Weber (1948) identified an opposition between a scientific epistemology and an associated scientific view of the world, on the one hand, and a hermeneutic view on the other. More recently, Habermas has placed this opposition at the centre of his analysis of modern, technological society. He calls the belief that a logical-empirical view of science is the only valid path to knowledge, 'scientism' (Habermas, 1968), and the associated view that it is only action based on this view that is effective may be called 'technicism'. These theorists and others have associated scientism with the role of education systems, bureaucracies and the knowledge-based professions in modern, technological societies (cf. Ellul, 1965; Habermas, 1968; Radnitsky, 1969; Friere, 1972). Scientific knowledge has come to occupy an increasingly important place in modern, industrial societies. Hand in hand with the growth of scientific knowledge has been the 'rationalization' of government and private bureaucracies and their extension into wider and wider spheres oflife. The key roles in bureaucracies have increasingly been occupied by professionals or ex- Downloaded from aed.sagepub.com at Monash University on June 16, 2015 198 Australian Journal of Education perts. More and more occupational spheres have been subject to professionalization, the adoption of specific courses of training and certification, the identification of a particular sphere of expertise and/or appropriate 'scientific' knowledge base, and the organization of the profession to maintain these standards and to enhance its status in the wider community (Parsons, 1958; Clark, 1962; Halmos, 1970; Johnson, 1972). The growth of bureaucratic organizations and professionalism has been bidirectional. In addition to a quantitative increase in these social forms, there was a lateral extension of them to areas of life previously thought to be beyond the sphere of efficacy of either rational decision making or a professional knowledge base. Much of the growth, then, can be accounted for by the spread of rational-scientific modes of thought and action from the technologies of the physical sciences to the 'humanities' and the 'people' professions, such as teaching (Halmos, 1970; Clark, 1962). Education systems, in turn, have been increasingly integrated with the occupational structure, and the rise of higher level vocational and specialized courses and qualifications has meant that integration has become increasingly functionally related to curricula and teaching (cf. Clark, 1962; Musgrave, 1968; Cosin, 1972). Teaching has followed the same trend, with the introduction and development of more and more elaborate courses of professional training and the increasing influence of the behavioural sciences in pedagogy. Schooling, too, has become more and more instrumentally related to vocational aspirations (cf. Musgrave, 1968, p. 139). Similar analyses have been made by many others: positivism or 'logical empiricism' is increasing its influence, while hermeneutic views of knowledge are in decline (Ellul, 1965; Radnitsky, 1969). EXTENSION OF BERNSTEIN'S ANALYSIS The findings of the ethnographic stage of the research were then related to Bernstein's theory concerning the forms of teachers' pedagogical and curricular ideologies. Bernstein's approach was essentially a 'structuralist' one. He dealt with the form of 'transmissions in educational agencies'. His analysis had 'little connection with any institutional or ideological features outside the school' and the concepts of 'classification' and 'framing' which he employed were 'defined without reference to content' (Bernstein, 1975, pp. 8-9). In the course of the present study, the links between the form of educational transmissions, the institutional location of schooling systems, and what Bernstein calls 'dominant cultural codes', were explored. It was argued that the formal properties of the curriculum codes Bernstein identifies were present in particular societally dominant epistemologies and were supportive of a particular sort of institutional relationship between schooling and society in general. Thus, particular ideological content and particular institutional relationships were found to be present and to possess the appropriate formal properties Bernstein (1975) identifies. 'Classification' and 'framing' relate respectively to the degree of separation or boundary maintenance which occurs between school subjects and to the 'control over the selection, organization and pacing of the knowledge transmitted and received in the pedagogical relationship'. In an integrated curriculum code Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 199 weak classification and weak framing result in 'the subordination of previously insulated subjects or courses to some relational idea' (Bernstein, 1975, pp. 231, 235). A collection curriculum code, however, involves strong classification and strong framing which result in the separation of distinct subjects and in a high degree of teacher control over how these subjects are taught. While the view of knowledge of a teacher is not the same thing as the view of curriculum, it is clear that one possible grounding of curriculum organization is in the teachers' view of the way human knowledge, in general, is organized. There are, moreover, additional reasons for a close link between a teacher's view of knowledge and his or her view of curriculum. If, as has been argued above, a particular view of knowledge has become part of society's 'dominant or dominating cultural code' (Bernstein, 1975, p. 20), a form of curriculum organization consonant with it will be more likely to be viewed as legitimate than otherwise. In addition, such a view of knowledge, if manifestly linked to the curriculum, can provide legitimation for wider spheres of pedagogical activity, such as assessment processes. Other corollaries of any particular view of knowledge, such as the account of what it means to know and the identification of particular persons as knowers may also be related to the pedagogical processes. The relationship between epistemology and curriculum code is examined first and the analysis is then widened to explore the further implications of epistemology for other aspects of pedagogical ideology. EPISTEMOLOGY, CURRICULUM CODE AND PEDAGOGICAL IDEOLOGY In this section it is argued that teachers' epistemologies are related to curriculum codes both because they support the forms of encoding which take place, and, in the case of the most common views, because they have wide societal support, thus conferring legitimacy on certain ways of organizing the school curriculum. It will further be argued that similar connections occur between epistemologies and two crucial areas of pedagogical style: assessment processes and teachers' approach to pupil control. Taken together, epistemologies, curriculum codes, assessment approach and approach to pupil control constitute elements of a coherent pedagogical ideology. The formal properties of both scientism and the 'forms of knowledge' approach meet the requirements of a collection curriculum code in respect of strict boundary maintenance between entities (concepts, ideas, etc.); in addition, epistemologies of this type suggest, by their emphasis or strict logical rules for the grammar and syntax of the articulation of propositions, that such a curriculum code would display preferences for 'logical' discourse (cf. Hirst, 1965, p. 115). Both scientism and the forms of knowledge approach also emphasize 'objectivity' (Hirst, 1965, p. 115). The hermeneutic approach does not meet these requirements, focusing instead on the dimension of personal preferences, on the problematics of the individual's own projects, and hence meets the requirements for an integrated curriculum code with its problemcentred organization. The area of 'framing' may be more complex than the area of 'classification' since it refers to the selection, organization and pacing of knowledge transmitted, in short, to the complexities of pedagogical processes. If a teacher's ap- Downloaded from aed.sagepub.com at Monash University on June 16, 2015 200 AustralianJournal of Education proach to curriculum were based on the teacher's epistemology, it is clear that some aspects of epistemology could he related to framing as well as to classification. For instance, a preference for logical relations between propositions would be likely to influence a teacher's style of presentation of material, choice of textbooks, certainly organization of material, and finally, assessment (cf. Esland, 1971). Again, a teacher's preference for certain modes of experience would affect the teacher's assessment of particular sorts of evidence and particular lines of argument. This is because the image of knowledge acquisition in particular epistemologies - the image of primary knowledge acquisition we might call it - is likely to affect teachers' images of secondary knowledge acquisition, the communication of previously discovered knowledge to others. In this way, for instance, a hypothetico-deductive model of scientific discovery could result in a discovery-oriented pedagogy in say, science classrooms, and thus profoundly affect the selection, organization and even pacing of the knowledge transmitted. But in this process of secondary acquisition the teacher is likely to carry over the same set of rules for doubt and certainty, the same epoch!, or taken for granted dimension as in the original context of discovery. The epoch! of the logical empirical view of science, as outlined by Schutz (1973), is an epoche which brackets the subjectivity of the knower and the relationship of the knower to the knowledge. The personal concerns, projects, feelings, the whole inner dimension of the knower, are bracketed in the scientistic approach to knowledge. The implications of this for pedagogy and for the role of pupil insights, feelings and intuitions in the various processes of pedagogy is obviously an important area of concern. Thus, as Bernstein argues, pedagogical styles should be studied in terms of approaches to control and assessment, as well as in terms of curriculum codes. In what he calls a 'visible' pedagogy, the teacher has explicit control over the child. This control is enhanced by the existence of an 'objective' grid which provides clear criteria for assessment and an appropriate procedure of measurement (Bernstein, 1975, p. 130). The presence of a grid of this kind dearly enhances the presentation to the public of the school's role in social reproduction as an 'objective' and independent one. A crucial feature of this assessment process is its ability to distinguish between pupils in standardized ways for the regulation of access to scarce status positions in society, and at the same time to provide the teacher with an overt measure of the acquisition of knowledge. Assessment in 'invisible' pedagogies is more frequently 'covert' and based on individual growth and development rather than competitive comparison (Bernstein, 1975, pp. 129-33). In practice, however, the constraints which operate on classrooms and teachers may enforce a degree of competitive assessment (Sharp and Green, 1975). Overt control is consistent with the models of the child and oflearning which occur in a 'visible' pedagogy. In a visible pedagogy learning is seen as the acquisition of skills and knowledge by the student, in collection-type secondary schooling it is essentially the mastery of 'subjects'. This is an approach to learning which is subject-centred (Barker-Lunn, 1973). The curriculum which accompanies it is organized on a subject basis and on the assumption of progression through a cognitive hierarchy. The student, in turn, must be con- Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 201 trolled in such a way as to conform to the externally paced and structured task. The assessment process is geared to measure the degree of achievement of the pre-defined cognitive goals and skills. Bernstein's visible pedagogy is related to the collection curriculum code and its characteristics are consistent with strong framing. It is also more likely to be associated with strong classification, since the assessment process is simplified by the employment of distinctive subject-derived criteria and is more easily legitimated and presented as objective if tied to the external demands of a subject rather than to criteria derived from the student's own problematic. In an 'invisible' pedagogy, the model oflearning is a tacit one. The student] capacity for exploration of the environment and active participation in its own cognitive development is emphasized. This is a child-centred approach to learning. The curriculum which accompanies it is problem-based and childbased, allowing integration of approach. The assessment process is covert and individual. There is less pressure on the teacher to induce the child to conform to externally-derived criteria of task. Bernstein's visible pedagogy is probably still the most common one in our schools. The reasons for this may be many. Firstly, it is an approach which facilitates the socialization of new teachers 'both at the level of role and at the level of knowledge' (Bernstein, 1975, p. 108). This pedagagy is 'likely to be continuous with the teacher's own educational socialization' (Bernstein, 1975, p. 108). Secondly, given certain assumptions about the typical features of contemporary classrooms, e.g. the one-to-many relationship, the medium of instruction, the instrumental rather than intrinsic motivation of parents and children and the problem of control which looms larger than any other in the consciousness of most teachers, it seems reasonable to see a formal and objectivist view of knowledge such as scientism, and a related view of curriculum as providing an effective coping strategy for teachers. Australian secondary schools, like most secondary schools throughout the world, are characterized by the external constraints of the examination, the syllabus, and the instrumental goals of status-maintenance and statusachievement. Such systems present teachers with three demands. They must cover the work, ensure that students master it and manage or control classroom conduct and conditions so as to achieve these goals (cf. Westbury, 1973). The adoption of a view of curriculum characterized by strong classification and framing greatly assists in these tasks. It allows material to be organized into a clearly demarcated domain, the subject, which in turn allows easy identification and collection of materials (frequently textbooks). Materials of this kind minimize teacher preparation and allow the teacher to specify, especially in the case of textbooks, kits, reading laboratories, and the like, the activity that each pupil should be engaging in at anyone time. They both facilitate control and demand it, because the processes the student should be engaged in at anyone time are specified in the learning material and the teacher can continually monitor the level of coverage and mastery (cf. Westbury, 1973). But in addition to allowing the teacher to justify a collection organization of curriculum, the image of knowledge which is embodied in such a coping strategy must draw upon widely accepted epistemological views in order to Downloaded from aed.sagepub.com at Monash University on June 16, 2015 202 Australian Journal of Education legitimate, to parents and children, teacher claims to cognitive privilege and the outcome of assessment processes; and it must provide a basis for a definitive approach to the content of instruction (framing) which is compatible with assessment and overall curriculum organization. A science-centred image of knowledge based on a logical-empiricist view of science simultaneously performs all these functions, as does to a lesser degree the traditional 'forms of knowledge' approach. Thus, granted the way schools function in social reproduction in modern, technological society, and granted that scientistic views of knowledge are replacing more traditional approaches to knowledge, it appears that the visible pedagogy in schools has become allied with a scientistic image of knowledge and a technological image of practice (cf. Fay, 1975). It is appropriate then to call this type of pedagogical ideology (containing a visible pedagogy), 'technicist' and the other, rarer, invisible pedagogy because of its alliance with an hermeneutic epistemology, 'interpretive'. If such pedagogies exist, at least at the level of teacher beliefs, it should be possible to construct attitude scales based on them and it should be possible to show that a scientistic epistemology is associated with a preference for collection curriculum organization, an external, comparative and 'objective' approach to assessment, and a preference for a high degree of teacher control over pupils and what goes on in the classroom. And conversely, that a hermeneutic epistemology, with its stress on purposeful meaning and interpretation, is associated with an integrated curriculum code, an 'epistemic' or personal/developmental approach to assessment and a preference for active pupil participation in many areas of classroom decision making." Clearly many implications may be drawn from this theoretical position and there are many ways in which one might go about exploring the usefulness of this perspective, only one of which is pursued below. It is sufficient at this point to mention several other lines of empirical and theoretical development which are currently being pursued. Work in the style of 'discourse analysis' has begun to map the situated accomplishment of classroom life (McHoul, 1978; Mehan, 1973; 1979; Edwards, 1980). In this vein, some aspects of the epistemic work teachers do in classrooms has been examined in respect of Australian data (Watson and Young, 1980). Further theoretical work concerning the general role of asymmetrical structures of communication has also been proceeding (Young, 1980a, c). The present article reports the results of a survey of teachers' views of epistemology, appropriate assessment procedures, preferred curriculum organization and pupil control ideology (PCI). EPISTEMOLOGICAL TEACHERS' PEDAGOGICAL IDEOLOGIES: A SURVEY The four areas of teachers' pedagogical ideologies identified in the foregoing discussion were operationalized in the form of four Likert scales. Three of these scales were developed for the present study, and very careful attention was paid to validity" as well as to metric criteria such as factorial structure, size of item score/total score correlations, alpha coefficient and the like. The vocabulary and indeed the phraseology of all items were derived from frequently used vocabulary and phrases of teachers. At all stages of development interviews Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 203 and content analysis of critical comments on items were employed as a check on respondent perceptions of item meanings. Shifts in the relative emphasis of summated ratings scores due to shifts in item mix, as items were deleted from the original pool, were controlled, as was the possibility of semantic shifts due to the substitution of researcher vocabulary and phrases for those of teachers. All scales were balanced to avoid positive response bias. The four scales had final alphas in use of 0.73 (16-item Epistemology) (Young, 1980b), 0.69 (8-item Curriculum Code), 0.58 (4-item Assessment Approach) and 0.81 (17-item Pupil Control Ideology). But it is interesting to note that the original item pools of two of the three scales developed for the present study ran as scales with alpha coefficients greater than 0.8 on the first trial. The assessm&it scale had only four items to begin with and was not shortened. The fourth scale was a balanced adaptation of the existing Pupil Control Ideology Scale, which was already based on an appropriate theoretical rationale and contained appropriately worded items (Willower and Jones, 1967; Anderson et al., 1973; McArthur, 1975). Examples of items from the four scales are given: (i) Epistemology: 'Knowledge is always personal and subjective.' (ii) Curriculum: 'School subjects should be based on the existing forms of knowledge, each with its own characteristic concepts and methods.' (iii) Assessment: 'Pupils are not generally capable of sharing in the assessment process.' (iv) PCI: 'Teachers should consider revision of their teaching methods if these are criticized by their pupils.' The four scales were given to teachers in five Australian secondary schools (a different group of schools from those employed in the ethnographic study). A total of 152 teachers completed questionnaires, representing a response rate of 68 per cent. It was not possible to estimate non-response bias, although it is unlikely that this was large enough to affect interpretation ofthe results. School by school analysis of the data showed that the observed relationships obtained in all schools and that there were no statistically significant differences (p < 0.05) in the mean scores of the four scales obtained for samples of teachers in each school. In general, the variable scores met the requirements of normality, homoscedacity and linearity of interrelationship for product moment correlation and linear regression and factor analysis. First, pairwise correlations were examined (Table 1) and then the overall factor structure and multi-variate relationships were examined (Table 2). It is clear from the results set out in Table 1 that the variable epistemology is implicated in teachers' views about curriculum organization, assessment and pupil control and that further analysis of teacher ideology will have to take this variable into account. It should also be noted that the relationship between curriculum code, assessment approach and PCI, predicted on the basis of Bernstein's work, is even stronger. The variables were also examined by multi-variate analysis (Table 2). Maximum Likelihood Factor Analysis (ML) was employed to examine the ideological coherence which the theory suggested would exist between the various areas of teachers' pedagogical ideology identified.

This hypothesis was rejected. The SPSS ML program (SPSS Version 6.5 Supplementary Handbook) yielded a single factor solution with an X of 0.3677 with 2 degrees of freedom and a probability of 0.832. This indicates that the observed scores may be accounted for by only one statistically significant factor. Application of Kaiser's eigen value criteria also lends support to this conclusion since only the first factor generated an eigen value greater than unity (Kaiser, 1964). INTERPRETATION OF SURVEY RESULTS The results of this survey indicate, first, that teachers' epistemologies are an important part of their pedagogical ideologies and are therefore likely to be involved in the shaping of teachers' pedagogical practices and, second, that Bernstein's account of curriculum codes and pedagogies provides useful insights into the pedagogical ideologies of teachers. In passing, the evidence from this survey, and from the results of the ethnographic stage, does not support the view that teacher ideologies may best be described in terms of a conflict between traditional and progressive or open educational beliefs, but that at the very least a third ideological perspective exists, which is quite close to what Hoyle (1971) describes as 'nomothetic conservatism' and which in the present Table 2 Variables Epistemology Curriculum Assessment PCI ML Factor Analysis: Factor Matrix, Factor 1" Loadings Communalities 0.50 0.69 0.68 0.82 0.20 0.37 0.36 0.46 Eigen values: Factor 1 =2.36; F2=0.71; F3=0.73; F4=0.40 • The common factor explained 59.1 per cent of the total variance. Downloaded from aed.sagepub.com at Monash University on June 16, 2015 A Study of Teacher Epistemologies 205 study has been called 'technicism'. Technicism differs from 'traditional' views (cf. Kerlinger, 1967) in the area of epistemology while tending to coincide with it in its level of emphasis on control of pupils. There is a much greater coincidence between 'interpretive' views and those usually attributed to proponents of 'open education' (cf. Barth, 1972). If we were to look for theoretical enlightenment concerning technicism we should, perhaps, be looking in the direction of Ellul (1965) or Habermas (1968). CONCLUDING REMARKS It is clear that the inclusion of the variable 'epistemology' in both theory and research reveals aspects of teachers' ideologies which would not be so readily apparent without it. It also provides the theoretical possibility of an exploration of connections between societal ideologies and institutions, on the one hand, and the unfolding of reality construction processes in classrooms, on the other. Although, for reasons of brevity, the analysis presented above has been very schematic, and cast in terms of dichotomies, it is obvious that productive developments in classrooms must somehow break out of such antinomies. When should teachers be 'visible' and when 'invisible'? What role should student knowledge play in the curriculum? How can the classroom prepare pupils to cope with an epistemically pluralist world? These are but a few of the questions which research of this sort raises, but perhaps the central question educators must face, and this is a question which in some sense underlies all the others mentioned, is the question of moving towards a new and more useful definition of teacher authority - not an authority which manifests itself in a concern for control which is so overwhelming as to swamp the potential of the classroom for the creation of discourse, but an organic, functional and democratic authority with which individuals can be engaged in a dialogue and which progressively yields to their autonomy. NOTES The research reported in this article was carried out as a PhD project. I would like to record my gratitude towards the many people who helped me in the course of this study, and in particular to Professor Peter Musgrave, my supervisor, for his advice and criticism. 2 The study of teacher epistemologies is not, of course, the same thing as the study of epistemology or the implications of epistemology for education, that is a fundamental philosophical enterprise. s It should be noted that the identification of these epistemological views in the ethnographic research does not constitute an endorsement of any of them by the researcher. The researcher's own epistemological position is much closer to that of Habermas (1968). 4 Demonstration of the existence of a coherent set of attitudes (an 'ideology') is not, of course, the same thing as demonstration of a coherent set of practices. Research on classroom discourse which is at present underway (Young, 1980a) tends to indicate that the ~ap between theory and practice is likely to be greatest for teachers with hermeneutic views since the dominant form of classroom communication seems ill suited to these views and the view of knowledge which is most powerful in society at large appears to contradict the hermeneutic view. It should also be noted that the four elements of ideology examined in this study are not. intended to be exhaustive of teachers' ideologies. Clearly such elements as images of human nature may be of importance too. S Written statements of respondents' views of knowledge were also collected. Content analysis was employed to assign scores to the data and these were correlated with summated rating scores on the scales yielding, with one-way correction for attenuation, a correlation coefficient of r = 0.88, thus providing support for the validity of the scale. 1 Downloaded from aed.sagepub.com at Monash University on June 16, 2015 206 Australian Journal of Education REFERENCES ABBAS, A.
