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.

ItemThe academic achievements of language centre students at a secondary college( 2001)What are the academic achievements of adolescent new-arrival English as a Second Language (ESL) students at secondary schools in Victoria, Australia? Research on Non-English Speaking Background (NESB) students in Australia has tended to neglect new arrival ESL students. To examine the academic achievements of this important subgroup of NESB students, the current study will highlight the academic achievements of a cohort of Victorian Language Centre students at a Secondary College over six years with interruption to schooling in their first language (L1) as the key variable linked to academic achievement in their second language (L2). Victorian Language Centres provide new-arrival ESL students with the English skills they need to start their secondary educations in L2. The current study examined the academic achievement of two groups of Language Centre students, those who completed their Victorian Certificate of Education (VCE) and those who left the Secondary College prior to completing VCE. Their academic results were summarised into spreadsheets for quantitative analysis. Subsequent to the quantitative analysis interviews were conducted with four ESL students from the Language Centre currently completing their VCE studies to provide further insight into the factors that enabled them to do their VCE. Results indicate that the academic achievements of this cohort of ESL Language Centre students are poor and that interruption to education in Ll had a major impact on the students' ability to achieve academically at the Secondary College. The study suggests that L1 education is the key variable influencing the student's ability to acquire the academic language skills necessary to meet the academic demands of secondary education, particularly the VCE. Other factors such as support for learning and strong motivation were found to help students overcome difficulties encountered in their secondary education. However, students who were unable to overcome these difficulties left the College prior to completing VCE. It was concluded that the majority of Language Centre students faced uncertain economic futures once they left the Secondary College. The results of the study suggest that Language Centre students need more support and assistance to enable them to complete VCE or to access educational alternatives to the VCE. This study also suggests that more research into the effect of L1 education on L2 education be conducted as this was found to be the key variable in the students' ability to acquire the academic language skills necessary to meet the academic demands of VCE.

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 evolution of concepts of decimals in primary and secondary students( 1994)This thesis studies children's conceptions about ordering decimals. It builds upon previous work which established three commonly used systematic errors in children's understanding as they encounter decimal notation. Students were categorised according to erroneous rule usage. This work includes a small longitudinal study which showed little change over twelve months in rule usage by an Australian sample of 50 secondary students. The categorising tests were redeveloped to make them suitable for primary students and to have increased reliability. The main study traced the use of rules from Year Four to Year Ten in a sample of 379 students and showed how students with different rules performed on other decimal tasks. It was found that one of the rules, called the whole number rule (in comparing two decimals that with more decimal places is chosen as the larger) was important in earlier years but disappeared with time. The second rule, called the fraction rule (the decimal with fewer decimal places is chosen as the larger), persisted in worrying proportions well into the secondary years and it was shown that significant gaps in knowledge of decimal notation existed which had not corrected themselves with time. The third rule was shown to be not important. Further investigation of a longitudinal nature to examine how individuals actually make the transition to mastery of decimal notation is encouraged by this study.

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.

ItemThe new English : an analysis of ideology in the professional literature of English-teaching, 1963-1978( 1982)This thesis focusses upon the professional literature of English teachers in Victoria in the period 1963-1978. Its concern is, firstly, to identify and delineate the distinctive features of the successive ideologies of English teaching which emerged in the literature during those years, focussing in particular upon 'the New English'. Secondly, it seeks to suggest reasons for their emergence, by examining contemporary socio-economic, political and institutional developments, to which the theory of English teaching has been responsive. Although writers in the professional literature presented themselves as spokesmen for classroom English teachers, their rationales and pre-occupations were not widely shared or successfully communicated. Therefore, the theories of English teaching which are identifiable in the literature do not represent the changing practices of teachers, but rather a succession of 'attempts by theorists to direct and control those practices. They also reflect the changing composition and configuration of a particular segment of the intellectual field over a period of time. Some aspects of the changing ideology of English teaching are thus the product of quasi-autonomous internal processes of self-reflection and debate within the profession. However, the major purpose of this analysis is to demonstrate how more widespread historical developments called forth a specific range of responses amongst theorists, whose role was one of intellectual management of those developments. It is claimed that the New English merits attention both because of its congruence with broader structural changes and because of the challenge it offered to existing forms of control over both teaching practice and the production of theory itself.

ItemAn evaluation of computer science in the Victorian Higher Schools Certificate( 1984)This thesis evaluates certain aspects of the Victorian Higher Schools Certificate subject, Computer Science. Firstly, an overview is taken of the subject as it was intended to function in the first three years of its accreditation, 1981 - 83. In the light of this, the draft proposal for changes to the course in 1984 is reviewed. Secondly, a number of specific areas of the course are examined in more detail. A questionnaire to course designers and teachers is the basis of this investigation. The relationship between stated objectives of the course and items of course content is explored. An analysis is conducted on the extent to which the four option components are equitable in terms of time. The relative importance of the three components of assessment is explored, especially in the case of a 'barely passing' student. Actual raw mark components for the 1981 students have been used in connection with the latter investigation.

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.

ItemRelationships between modernism, postmodernism, new technologies and visual culture in Victorian secondary visual arts education( 2001)This study investigates relationships between computer technologies, modernism, postmodernism, visual culture and visual arts education. The literature research focuses on relationships between modernism and new technologies, modernism and postmodernism, postmodernism and new technologies and art education and computer technologies. The field research consisted of three 'semi-structured interviews with secondary visual arts teachers in metropolitan Melbourne, Victoria. I investigated selected teachers' perceptions of the extent to which they addressed computer technologies, modernism, postmodernism and visual culture in their visual arts curricula. Initially I aimed to discover the extent that they included computer technologies and postmodern theories into their visual arts curricula. I used a combination of research methods when undertaking this study and in particular when analysing the field research findings. The deductive method of Orientational Qualitative Inquiry was combined with the inductive method of grounded theory. Whilst investigating relationships between postmodernism and new technologies using Orientational Qualitative Inquiry I found that modernism impacted upon both postmodernism and computer technologies. I then used grounded theory to document the interrelationships between modernism, postmodernism, visual culture, new technologies and arts education. This study was limited by several factors, including the following. Firstly, I limited the investigation to only three participants. Secondly, there were flaws inherent in the combination of inductive and deductive research methods. Most significantly, I was limited by the fact that the three interviewees worked in modern institutions. The relationships between modernism and new technologies encountered in section 2.1 were echoed by the interviewees' comments, particularly in sections 4.1 and 4.2. The interviewees held strong modern values such as a belief in progress and the importance of originality. The investigations surrounding postmodernism and visual culture in sections 2.2 and 2.3 were less well established in the field research. However, these were still present, especially in section 4.3. Finally, the traditions of the incorporation of computer technologies established in Australian and American visual arts education in section 2.4 were continued by all three participants in chapter four and summarised in section 5.1. By exploring relationships between modernism, postmodernism, visual culture and new technologies in visual arts education I found that modernism and postmodernism are not mutually exclusive but rather deeply interconnected.

ItemWhat are the blockers/facilitators for a science coordinator to integrate datalogging into science teaching( 2002)This project investigates a coeducational Secondary College Science Department that decided to introduce datalogging as a teaching tool. Datalogging is the electronic recording of data during an experiment using sensor probes. Decisions concerning the introduction of datalogging involved the science teaching staff, the laboratory technician and the Science Coordinator, all stakeholders in this process. This investigation was developed with the hindsight of a Literature Review, which provided the advice of others' experiences and catalogues the introduction in a case study format. Action research strategies were invoked through a series of focus interview questions, which provide a 'snap-shot' of the perceptions. From here a collaborative Change Management strategy of introducing datalogging into science teaching was produced. The factors that inhibited or prevented the use of datalogging in teaching were considered to be 'blockers'. Through interview questions the teachers and the laboratory technician were asked what they felt blocked their use of datalogging. The time required to become comfortable, familiar, confident and experiment with the equipment arose as the major concern for all teachers prior to using datalogging in science teaching, while the laboratory technician had more physical impediments. The technology capable participants did not encounter major hindrances. There was a constant limitation of equipment due to its expense, which was a factor accepted by all and where innovation in teaching style was required to overcome this impediment. However, all felt that visual 'memory-jogs' of the availability and uses of the equipment would encourage use. The factors that contributed to datalogging use were the 'facilitators'. These included a well rounded, informative and ongoing professional development strategy involving all staff members sharing knowledge combined with a laboratory technician who was conversant with the equipment, constantly promoting and encouraging usage and aiding the process. Throughout the project constant active problem solving emerged as a strategy by teachers whenever a 'blocker' was suggested. The advantage of collegial sharing through professional development was also recognised by staff and thought to integrate well when developing technology as a teaching tool. The process overall was time intensive due to lack of time in the working week when people are at different stages in embracing change and technology. Consequently whatever was learnt by individuals was regarded as worth sharing professionally.
