ItemTeacher's management of learning in small groups in science classes( 1993)Established curriculum documents in Victoria recommend group work as an effective teaching strategy but the implementation and management of such groups is poorly understood by many teachers. This study investigated two management strategies which differed in the degree of role attribution amongst group members and the effect of the strategies on communication, behaviour patterns and achievement on a problem solving investigation. Students in three parallel year eight science classes from one school were observed over an eight week period. A low level and a high level management strategy were randomly allocated to each of two classes and used to manage group work. After four weeks the management strategies were exchanged. The third class, which was used as the control, was managed in a way which was more typical of a traditional science class. Randomly selected groups of students from each class carried out a practical problem solving investigation as a pretest, then again at the completion of the first four weeks (phase 1) and again after the completion of the second four weeks (phase 2). Student conversations within groups were recorded and coded to identify levels of communication types. Students' written reports for each test were assessed and scores analysed. Teachers completed an observation schedule to identify styles of leadership and types of group behaviour within each class. It was found that the use of the low level management strategy, in particular, did increase the relative frequency of communication at higher cognitive levels, those of conceptualisations, as compared with the control treatment. Problem solving skills as measured by achievement on the written practical investigation improved over time and there was a significant effect in the area of "making measurements" when the management strategies were used as compared to the control treatment.

ItemStudents, computers and learning : a conversation with the cognitive apprentices and their learning tools( 1998)Wertsch (1991) asserts the mind "extends beyond the skin", that is, it is socially distributed and is a function of activity involving cultural tools. From this perspective the mind is unlimited in the sense that it is developed and inseparable from tools of mediation of which the computer is a corporeal thing that extends out into the material world. The computer as a means of mediation can be invisible yet powerfully influential in shaping thought and communication.. In this small-scale case study in an academic independent school a representative focus group of year 9 students suggests to the Author, their school's computer specialist, that their teachers are not to be providing mediated learning with computers. The students who are the metaphoric "cognitive apprentices" feel the school as an institution has not 'grasped the idea.' Bryson and De Castell (1994, 215) observed that " ... the divisive playing field of educational technology is populated by various teams who are telling altogether different 'true stories,' each having different settings, characters and plots ..." The new age believers and the non believers were not listening to the users. Hargreaves (1996) offered a parallel critical assessment, after Plummer (1983) and Wood (1991), of the use of "voice" in contemporary educational research. He stressed the need for active participant voices outside conventional conversations, from different contexts, different positions and particularly the marginalised. In both educational practice and research, student's voice has frequently been considered " a nuisance; literal noise in the instructional system" (Cazden 1986, 448). However, if teachers and schools as agents of parents and society are to embrace computers as cognitive tools, and accept them into the educational context as a means to gaining one or more educational ends, then there is need to research the voices of the cognitive apprentices on their learning with computers. The collaborative nature of the ethnographic research was grounded in the mutual regard of the researcher and the practitioners (students) as change agents in their own school. Central to the research was the development and exploration of a clue structure to understand how student practitioners saw computers being used in their classrooms. The initial core questionnaire asked the students to position their opinion of the school's , and their teachers' use of computers in the provision of the curriculum on a continuum between; "Are computers instructional tools used by teachers to impart knowledge to you", or, "Are computers used as cognitive tools to afford students' opportunities to construct representations of their knowledge and understandings of the concepts being taught ?

ItemThe ideas of covariation and rate of change in introductory calculus( 1996)This thesis is a formative evaluation of a new curriculum which has evolved at a Victorian secondary school, with the aim of better preparing students for introductory calculus than has traditionally been the case. The new curriculum focuses on the ideas of the rate of change of the dependent variable and the covariation of the variables using tables of values to examine and emphasise the way that the function changes, before moving to the graphical and algebraic representations. This approach is in contrast to the more traditional curriculum where families of functions are introduced using the algebraic representation, and where the central ideas of change and covariation may be obscured. Because of inherent limitations of this study, it was not possible to produce conclusive evidence; however, the results gave a strong indication that the new approach shows promise for an improved understanding of students studying introductory calculus.

ItemAn evaluation of a short, intensive mathematics program( 1999)This thesis evaluates a short intensive mathematics program for primary and secondary students that was conducted at the University of Melbourne in April 1997. The methodology of the evaluation can be described as action-research: a collaborative investigation where researchers, teachers and students cooperate in order to gain insights into a specific learning environment. This process is conducive to various improvement and modifications that the participants can apply to their respective practices. The primary aim of the thesis was to explore factors affecting the success of such programs and the learning which results. The findings suggest that while mathematical self-esteem is closely associated with mathematical achievement actual changes in mathematical self-esteem might not be easily detectable in programs of such short duration. The strength of the Program seemed to be the 'learning atmosphere' fostered by the instructors as well as in the choice of non-routine tasks. A possible weakness was the lack of clear focus regarding the pedagogical aims of the Program.

ItemGhost stories : an ethnographic journey( 1998)This is an ethnographic study of a school theatre project, 'Ghost Stories'. The study explores what the role and nature of extra curricular theatre is in an independent boys' school. The concept of 'school theatre' is defined as an aesthetically rich, extra curricular event. The study argues that a teacher of 'school theatre' creates learning experiences for students that empower and challenge the politically or economically sanctioned educational culture. The value of school theatre, the role of the teacher, the development of students' artistic and personal skills and the relationship between school theatre and the dramatic heritage is investigated. The study argues that a believable, trustworthy account of the school theatre event needs to incorporate the variety of participant voices. The report is written in the form of a narrative and is told by the drama teacher responsible for the performance project, a male and female student, a teacher assisting in the performance project and a senior member of the administration. The narrative traces the participants' motives in becoming involved in the 'Ghost Stories' performance project, the various perceptions of the value of student devised performance texts, the conflicts within this educational context, culminating in the final night's presentation ceremony. The 'Ghost Stories' performance event challenges the conduct of teaching and learning in this educational context. The study contends that a teacher of 'school theatre is engaged in 'critical pedagogy'.

ItemA study of religious education in Catholic secondary schools : attitudes of students, content, methodology and gender issues( 1999)The subject of Religious Education (RE) is the one feature distinguishing Catholic Schools from Government Schools. It is a unique subject because its impact on students' lives is long-lasting and important. The factors influencing students' attitudes and perceptions of RE are examined in this study. Two of the main factors researched here include the content of Religious Education lessons and the methodology employed by teachers, as perceived by students. Marked differences in the gender responses of students were observed to be very significant and these are discussed and explored. Recommendations for possible ways of addressing these disparities are also included.

ItemLearning geometry : Cabri-geometre and the van Hiele levels( 1998)The relationship between the van Hiele levels of learning geometry and pupils' use of the dynamic geometry tool, Cabri-geometre, was investigated using a case study approach. Twelve Year 7/8 students explored aspects of the geometry curriculum using Cabri in conjunction with structured worksheets. Pupils were divided into two groups on the basis of van Hiele pre-tests. Group I comprised students who were at Level 0 or 1, or in transition to Level 2, on most of the concepts: Parallel lines, Rectangles, Right-angled triangles and Isosceles triangles. Group II comprised the remaining students, who were at Level 2 on most of the four concepts. On completion of the worksheets, Group II pupils were required to construct drag-resistant shapes: rectangle, parallelogram, right-angled triangle and isosceles triangle. Following completion of their designated Cabri activities, each student was given a van Hiele post-test. Selected Group H pupils were then given further construction tasks. Students' constructions were documented by means of their saved Cabri files and tape-recorded conversations. The history facility of Cabri enabled the retracing of the students' construction steps. After six lessons for Group I students and seven or eight lessons for Group it students, eleven of the twelve students had progressed a level in two or three concepts. This may be compared with the 20 lessons to take pupils from Level 1 to Level 2, and 50 lessons for progress from Level 2 to Level 3, reported by Dina van Hiele-Geldof. Group II students generally commenced their Cabri constructions by eye but progressed to Level 3 thinking in some constructions. The use of the Cabri menu items enhanced the students' use of appropriate geometric language and there was some evidence that Cabri influenced students' ability to recognise geometric figures in non-standard positions.

ItemAn analysis of the structures and contexts underlying adolescent speech in the secondary school : the implications for developing a language policy in the secondary school( 1991)The purpose of the study was to investigate the extent of speech variation across different school contexts and explore the implications for policies on spoken language in secondary schools. In order to measure changes of speech resulting from different contexts, it was necessary to identify a form of analysis sensitive to speech variation. A number of approaches were examined including syntactic and functional analysis. The units of speech used by various studies included the speech act, the exchange and the episode. A review of the literature regarding the contextual variation of speech and the concept of 'communicative competence' was carried out as well as an examination of a number of studies of language in schools. Attention was also given to policy statements on spoken language in secondary schools. A functional analysis at the level of the speech act was identified and modified to match the study. Analysis of interrogative and assertive exchanges was also carried out, the latter being identified in the course of the study. Samples of student speech over a variety of contexts were collected and analysed. The study identified links between school context and pupil speech. A profile of school context, functional outcomes, and the speech forms used, was then compiled. The formal classroom was found capable of inducing abstract levels of speech involving evaluative and speculative activity. Other forms of speech such as verbal planning, reflection, the interaction of ideas and the negotiation of meaning, require careful planning if they are to become part of the linguistic experiences of pupils in secondary schools. A number of implications for a policy on spoken language in secondary schools have been raised and directions for further research put forward.

ItemSearching for a fair assessment( 1995)The full implementation of the VCE in 1992 represented significant changes to senior secondary schooling in Victoria. These changes were strikingly evident in the new assessment methods and procedures of the Art test CAT. The difference between the HSC Art Appreciation examination process and the 1992 VCE Art test CAT assessment was more than a difference in practices and methods. The ideological foundations of the two examination systems were vastly different. The HSC system served to rank students so that universities could select the best candidates. The BOS promoted the VCE as more 'equitable', 'accountable' and 'inclusive 'than the HSC. These concepts derived from the recommendations of the Blackburn Report (1985) which advocated major reform of the senior curricula and assessment. I interviewed five experienced Art Appreciation examiners in order to acquire a perspective of the two examination systems during' a time of change (1987-92) and ultimately focused upon the fairness values that were evident in the examination process. I compared published policy statements regarding fairness and equity with the examination practices that the five examiners described and analysed during our interviews. The theories of Foucault and Bourdieu enabled me to understand that examinations are part of a systematic social selection process. How can 'fairness' be defined and embodied in examination practices if examinations inherently represent a form of social power? Bourdieu and Foucault nourished this type of reflection. The Blackburn Report, the views of the five examiners and the social theories of Foucault and Bourdieu led me to consider the Art test CAT (1992) as a representation of the equity values that were defended by the BOS. Fullan's theories revealed that disorder usually accompanies educational change and added -another dimension to this investigation of 'fairness and justice' in the Art Appreciation examination (1987-92). In addition, this research study evaluates the practice of the BOS policy regarding equity and fairness, as evident in the VCE Art test CAT assessment process (1992), because the Board promoted the view that the VCE would provide greater equity and fairness to all Victorian students than the HSC.

ItemStudents' early understanding in calculus( 1991)Students' Early Understanding of Calculus The study undertaken here looked at difficulties associated with the first principles approach to the derivative of a function and concentrated in particular on the first five lessons in calculus as experienced by a typical group of nineteen year 10 students who were preparing to take calculus at year 11. A traditional teaching approach was contrasted with an alternative computer teaching approach and both approaches were analysed for success in terms of conceptual understanding, skill acquisition and student perceptions of whether the work was easy to understand. As calculus has served as a critical filter for further study in mathematics, teaching methodology and student attitudes to the topic were a focus of the study. It was found that the students in the study had a limited concept image for gradient ('measure rise/run') and that a greater development of the global ideas associated with the gradient of a straight line needed to be a focus of learning before the idea of gradient of a curve should be introduced in beginning calculus. It was found that the use of a tangent to a curve at a point to measure gradient of the curve was not a spontaneous intuition and it is recommended that more time be given to this notion in the first principles approach to differentiation. The traditional first principles approach was found to be too cognitively demanding for the students who demonstrated a 'rush to the rule' for meaning. Students undergoing the computer treatment also demonstrated this 'rush to rule' and therefore very gradual development is recommended for students in their first encounters with calculus.
