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.

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.

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.

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.
