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.

ItemA cartoon chemistry text : the construction and testing of a novel chemistry text incorporating human values( 1990)This study examines current science texts and the concerns and objectives of Science-Technology-Society based courses. It indicates that they present the public image of the practising scientist (with inherent Mertonian values of Universalism, Communism, Disinterestedness, and organized skepticism) which is used to organize scientific concepts into a meaningful whole. Utilizing the notion that a value is anything important to a student, a hypothesis was proposed that meaning and interest generated from a text is dependent on the extent of overlap between text and student values. The implications of the interaction of different value systems with a Mertonian based text were considered. An attempt was made to develop a chemistry text that was meaningful to all students, by organizing concepts into a story form with non-Mertonian organization. This approach evolved into a cartoon format with specific features. Two cartoon text items were tested at two schools. The trial involved a survey item on 103 students and audio taped interviews with 20 students. The trial attempted to evaluate the cartoon as a student text, attitudes to issues content, and styles of resolving issues based conflicts. The results were interpreted by classifying the respondents into four categories of science likingness ( A, B, C, D) on the basis of Year 11 subject choice, and favorite subject. It was assumed that the accommodation of Mertonian values by a group reflected the science likingness of the group. The cartoon text was well received with most students wishing to see more cartoons, and being able to answer questions from the text. The B, C, and D groups expressed a preference for the cartoon text over their current science text. The proposed differential accommodation of values appeared to account for the greater enthusiasm of the B and C groups for the cartoons than the A and D groups. Perceptions of the amount of current social problems/ issues content in science teaching increased markedly with group science likingness. The amount of issues content desired decreased with increasing group science likingness. A belief that scientific solutions could resolve social problems/ issues, showed a marked decrease with decreasing science likingness. A value model of cognitive style was developed from the basic hypothesis and assumptions regarding the extent of accommodation of Mertonian and Humanist norms as personal values. This model seemed to account for variations in meaning generated for the various groups in response to both the standard and cartoon science text format.

ItemAn examination of the role of the Bridging into sciences program within the Victorian TAFE sector( 2002)The intention of this study was to examine and describe the role of the Bridging Into Sciences (BIS) program, a course of study conducted within the Victorian TAFE educational sector. BIS was originally developed in 1985, as a means of providing basic grounding in biology and chemistry for mature-age students seeking entry into health science-related university courses. Since that time, it has undergone several curriculum additions and changes, TAFE re-accreditations and was now taught a four different Victorian TAFE institutes. The updated BIS program was designed to form a link between unemployment and academia, providing a suitable entry point for individuals without suitable academic background. Like the old course, the new BIS version was intended to provide learners with vital underpinning theoretical knowledge and practical skills in both mathematics and the sciences, facilitating articulation into courses of science-orientated study, at a higher level of sophistication. However, unlike the old course, the new BIS program proposed to offer learners multiple exit points, and hence, multiple academic destinations. But was the new BIS program version fulfilling its intended aims, philosophies and intentions ? What sort of students undertook BIS studies ? Was the program able to provide multiple exit point for those successfully completing it ? Were students able to successfully undertake the BIS program and fulfil their specific academic goals ? If so, in which courses of study were they able to articulate into ? Were all students successful in completing BIS ? If not, why not ? Were the aims and philosophies of those teaching in the program consistent with those of the course designers ? Could the program be improved ? If so, how ? Overall, was a true and accurate 'picture' of the role of the Bridging Into Sciences program within the TAFE sector ? A desire to address these questions and formulate true and accurate insight of how BIS was operating, provided the impetus for, and aim of, this study. To achieve this aim, data from all four TAFE institutes was sought. To establish a 'rich and thick' understanding of how the program was operating, both qualitative and quantitative data collection methodologies were employed. Data was collected from three different sources - curriculum documents, ex-students and teaching staff members, via three different methods. First, relevant curriculum materials were collected and carefully examined. This established the program content, as well as overall aims and philosophies. Second, a questionnaire was designed, trialled and mailed to a select group of ex-BIS students - those having been enrolled in 1997. The mail out survey was to gather demographic information, as well as solicit opinions about their BIS experiences, from a cohort of individuals comprising of those who had successfully completed the program, and those who had not. In doing so, a 'snap-shot' of BIS, from a student prospective, would be obtained. Raw data generated was subsequently analysed using the SPSS computer software. Third, a number of teachers instructing in the BIS program, were interviewed in 'face-to-face' fashion. Teacher responses were tape recorded during interview and were later transcribed and analysed. The findings of the study revealed that in 1997, the BIS program was undertaken by students who were typically Australian-born, English-speaking females, aged somewhere between mid twenties to thirties and had at least one child. Members of the group were also likely to have completed at upper secondary school and were specifically involved with the BIS program to gain entry into either a TAFE or university course. Although almost 70% of BIS students were successful in completing at least one module, financial difficulties and seeking employment were the two main reasons for individuals having to discontinue their BIS studies. Of those successfully completing the program, almost two-thirds were found to be engaged in some form of post-BIS academic endeavor. BIS teachers were found to be a group of highly experienced professionals, averaging almost five years of involvement in the program. It was their collective belief that whilst the program was providing students with vital underpinning theoretical knowledge and practical skills, it also developed self-confidence and personal empowerment. In doing so, it was able to prepare students for studies at higher levels, both from theoretical and practical perspectives. Collectively, they agreed that the overall program was successful in achieving its aims, philosophies and objectives.

ItemWhat is a quality rubric? : curriculum design, state frameworks and local assessment of secondary science( 2009)In explicating Science the science teacher is likely to say, 'I have reached Chapter 9!' Bureaucracy has its own logic and State curriculum writers have pushed for results that looked rational: results that could codify, sort and explain to their masters. The schools and universities have responded. The rubric has recently entered the teacher lexicon as a quasi professional tool for instructional planning and student assessment in the public domain as a response to central accountability requirements in relation to mandated curricula and standards of student and teacher performance. The rubric is characteristically a grid which defines any piece of instruction, a list of anticipated educational attainments, stated as criteria, against levels or standards of attainment, stated as descriptors. The rubric has become a public statement, a quasi contract written by groups of teachers in a school that identifies what can be expected in terms of teaching behaviours and student learning, in the name of a school or the state. But how would the quality of a rubric be discussed or assessed in relation to science education? The study explores the use of rubrics to support situated cognition and social constructivist science teaching. This thesis does not investigate the question of educational 'quality' per se. It does not set out to prescribe or stipulate ideals. Nor does it recommend how teachers ought to use rubrics to measure or assess such ideals. Rather it is an ethnogenic study of the judgements made about the qualities of the rubrics designed and used by science teachers and a particular group of students in an inner urban secondary school. The students in this study are enrolled in the Select Entry Accelerated Learning program at Hill View Secondary College which seeks to engage them in higher levels of educational involvement and attainment.

ItemBeyond school science: students and teachers perceptions of the science talent search( 1986)Every year the Science Teachers Association of Victoria (STAV) conducts a Science Talent Search (STS) which they maintain is one of the largest and longest running science fairs in the world. This study aimed to provide some insights into why this activity is so popular with students and teachers and to what extent it complements or provides outcomes different from school science. Information was collected by searching the archives of STAV and by interviews with teachers and students. The findings indicate that over the years STS has adapted to changes in the social and economic contexts of schooling, which have also influenced thinking about but not forced major changes in the secondary school science curriculum. This has contributed to its increased popularity with keen students and teachers as evidenced by increased participation. The students who were interviewed enjoyed and valued their experiences in STS. In particular they commented on the freedom to choose projects according to their abilities, interests and preferred modes of working. Many of their projects arose from every day life problems or recreational pursuits of themselves and their families. STS catered for a wide range of abilities and interests and provided an attractive forum for the involvement of girls in science activities. Girls said that they had gained great satisfaction from confirmation of their ability to meet challenges and solve problems relying mostly on their own resources. Based on students responses some distinctions can be made between school science and the science activities of the STS which indicate ways in which school science may need to change in order to attract and cater for a wider range of students.

ItemNegotiating and enabling change in a primary school: identifying strategies that assist classroom teachers with the teaching and learning of science( 2006)The purpose of this research was to investigate strategies that assist classroom teachers with the teaching and learning of science. The researcher, a classroom teacher and science coordinator at Karingal Heights Primary School (KHPS), decided to conduct the study because of the researcher's desire to improve current practices at KHPS. The researcher's belief that, examining current practices, investigating alternatives and documenting what works for individual teachers are essential elements for successful teaching and learning. The methodology of action research was the most appropriate tool because it allowed for collaboration and reflection. The research period was ten months and involved classroom teachers at KHPS in a process of inquiry and. reflection. Classroom teachers became active participants in identifying strategies that assisted.them with the teaching and learning of science. Finding links to science across the curriculum led to a wider vision of what constituted science and resulted in more science happening at KHPS. Action Research became a strategy that promoted science teaching and learning because it provided classroom teachers with a focused process of investigation and reflection. What emerged was a broader view of science, linked more to the lives and interests of the school community and the conclusion that, although a variety of strategies assist classroom teachers with the teaching and learning of science, collaborative work practices emerged as the most valuable strategy for the classroom teachers at KHPS.

ItemThe Public understanding of techno-science in a rural community: culture & agency( 2003)This is an ontological inquiry into the public understanding of techno-science, held by adult members of a local school community. In this light, it seeks to establish a platform from which to reassess conventional assumptions about the curriculum and cultural agency of science teaching. The inquiry is rooted in dissatisfaction with a current transformational model of science teaching, which is defined solely in terms of the transfer of ideational possessions to the students in science classes. Both teachers and students are agents in their own and others' symbolic life worlds. Their identities are constructed in a dual praxis, a dialogue between self as product and self as process in every day conversation in established communities. The study draws on the work of Coulter on Dialogical Research, Harre on the analysis of social episodes, Latour, Rechwitz & Schatzki on the place of the material in theories of culture, of Harvey, Ratner on Agency and Community . Through dialogues with persons in a rural community served by the author's school, the thesis explores the public understanding of techno-science within the community and considers whose interests the school education in science best serves. The centrality of "community" is claimed in characterising a model of embodied cultural change over centrally imposed change. It is proposed that change is a "two-way" interaction where the individual "agent" both socialises & is socialised by the cultural structures that exist, and where the "artefact" is the "knot of reasoning" at the centre of personal identity formation "actor-networks" (ANT - Latour). It suggests that society empowers or does not empower - through the processes of recognising, and allocating control of empowering artefacts to persons as agents working within a social & cultural framework of responsibilities and duties. The thesis offers a new transformational model of social action, which suggests renewed attention in research & practice should be given to ontologies of the mind and person of the agent and the mediating function of "community" in the future restructuring of the public education of science if it is to serve its broader function in cultural transformation within the small rural community of Erehwyna, or anywhere.

ItemOrigins and development of general science in Victoria 1942-1962( 1976)This thesis is a detailed study of the teaching of General Science in Victorian secondary schools during the period, 1942-1962. The beginnings of the General Science movement can be traced to investigations into science education in England in 1918. However, many ideals of the subject date back to the nineteenth century. Hence some time has been spent in researching the aims and practice of science teaching in England during these earlier stages. Similarly, it has been necessary to study early science curricula in Australia. This background allowed an analysis of effects that Nature Study courses, university science subjects and any unique aspects of Australian education may have had on the origins and implementation of General Science. Syllabuses, courses of study, examination papers and examiners' reports have been thoroughly studied to determine the nature and direction of teaching that took place. In particular, the effect of subject content, examinations, text books and teaching methods has been researched. Hence it has been possible to analyse critically the origins and evolution of General Science. This retrospective study has not only allowed close scrutiny of the ideals and actual classroom practice of the time; it has also afforded valuable insight into essential guidelines that are necessary for general curriculum evaluation and development. Many of these guidelines remain relevant today, even though some thirty years have elapsed since the first General Science course was adapted in Victoria.

ItemAgency and communion in science teaching( 1991)The construction of the concept map assumes that the more closely two concepts are related in a person's cognitive structure, the more closely they will be placed on the concept map. In this research the Non-metric Multidimensional Scaling technique using ALSCAL (Alternating Least Squares Scaling) is used in the analysis of the concept map data, derived by surveying teachers from three different groups. Group 1 consisted of practicing teachers from a non-science background who taught Health and Human Relations. Group 2 consisted of Diploma of Education student teachers whose methods were Science and had completed their course though were not yet practicing teachers. Group 3 consisted of practicing teachers from a science background who taught Health and Human Relations. The results provide a basis for discussing the wisdom of practice, the maxim which provides reflective rationalization for the practices of able teachers. In this study, the wisdom of practice has been described with a focus on the responsibility of care. The findings of this study have confirmed those of earlier studies, in that it is apparent that experienced able teachers use their knowledge of what works in the class to organize their instruction. However, just what works is seen to depend on the subject the topic is taught in, as well as any perception of the subject held by teachers, students and the community. Teachers from each of the three Groups were able to organize their concept maps and provide satisfactory support material from transcribed interviews to indicate that the conceptual relations seen in the tension which exists between the concept of care and the concept of the academic is able to be described quantitatively.

ItemResearching teacher agency in primary school science: a discursive psychological approach( 2004)This ontological study is concerned with analyses of the problem of the scientific reform of the primary school curriculum. It was conducted at a time when a solution was sought through State mandated curriculum and standards specification and primary teacher accountability. The case study developed as an interactive ethnography (Woods 1996) written from the point of view of the facilitator of a whole school science curriculum project. The focus of the enquiry emerged as an exploration of social episodes in the life of two experienced Early Years teachers engaged in the yearlong project. Discursive psychology became the theoretical framework for the analysis of the primary teachers' professional identity formation in their professional work=place conversations with the author. Pronominal coding has been used to mark the teachers' psychological location in their storylines of the implementation of enquiry-based science education in their classes. In the teachers' accounts they simultaneously position themselves in their acts and actions and in the local moral order of duties and responsibilities. A significant disparity is shown to exist between the ontologies of the primary teachers' and research accounts, which present mental state analyses of teachers' lack of confidence or reluctance to teach science related to limited scientific understanding. The. study offers a schematic model of social action that theorizes human agency as, developing and functioning within the interactional nexus of local community settings. The community operates in the lives of these teachers not as a latent, abstract concept; instead it gives ideological differences and teachers' understandings of themselves significance in everyday educational practices.
