    A cross-age comparative investigation of students' attitudes towards computers as a tool to support learning in years 7-12 science classes
    Waddington, Carolyn ( 2000)
    This thesis documents a cross-age comparative investigation of students' attitudes towards computers as a tool to support learning in Years 7 - 12 science classes. The study was set at the secondary school campus of an independent girls' school in Victoria. The secondary school is broken into three relatively autonomous groups, the Junior Secondary School (JSS), the Middle School (MS) and the Senior School (SS). Data was collected by a survey administered to 1215 students in Years 7 -12 science classes. Results of the survey were analysed using Analysis of Variance (ANOVA) and post hoc Bonferonni analyses. This study aimed to investigate the ways computers are used in science classes. Word processing and the internet were the most common computer uses across the school. A comparison of students in JSS, MS and SS's preferred frequency of use of computers in science classes was undertaken. JSS students preferred to use their computers more frequently in science classes when compared to MS and SS students. An investigation of the uses of computers in science classes that students found beneficial to their learning of science concepts was undertaken and compared across the three school groups. Students' attitudes towards computers as tools to support learning in the science classroom was investigated. The majority of students in all school groups felt the computer was a beneficial support for learning when completing assignment work and was a beneficial tool for presentation. However, it depended on the number of years of computer experience in science classes as to whether students felt the computer was of benefit to their learning of theory or practical work. Aspects of computer use at school in general, that students liked or disliked was determined. The stage of the curriculum that students were currently in, was the major determinant for the students' attitudes towards the use of computers as a support for learning.

    TIMSS : a question of validity
    Malatt, Dianne ( 2000)
    The Third International Mathematics and Science Study (TIMSS), the largest comparative study of its kind, was administered to approximately 500,000 students worldwide. In Australia, the results of this study are being used to compare our students and schools to other students and schools around the world. The results may also influence decisions about curriculum reform and allocation of educational funding within Australia. This thesis sets out to investigate the TIMSS test items for Population 2, with the objective of determining the degree of validity of these test items to Australian mathematics teachers and their students. By eliciting feedback from a sample of Australian mathematics teachers, their thoughts on the validity of the TIMSS test items were documented. This was achieved through a mail out questionnaire that included a representative sample of 32 TIMSS test items from population 2. Four review questions were developed to target teacher beliefs as to whether enough content had been taught to Australian students by the time TIMSS was administered, the validity of including such items in the TIMSS study, the usefulness of the TIMSS test items for ascertaining student competence, and student familiarity with the item styles used in TIMSS. The results from the questionnaire were used to establish the overall validity of the TIMSS test items to Australian Mathematics teachers and the students they teach. In total, 154 teachers, representing Government, Catholic and Independent schools, from around Australia replied to the questionnaire. The study found widespread variability in the type and amount of content taught by teachers to their Australian students. Consequently, differences in content validity of the TIMSS study were found to exist across Australia. These differences appeared to be more apparent between states and territories than between school sectors. Respondents also expressed concern about the general appearance and layout of the TIMSS test items. In particular, some of the language used in test items relating to Proportionality, appeared not to be used in Australian classrooms. In addition to this, teachers reported that the TIMSS test items were not particularly useful for ascertaining student competence. This casts doubt over the value of any inferences made from the results of TIMSS. Furthermore, this research found significant variability in student familiarity with the item formats used in the TIMSS study. Overall, students were found to be most familiar with the short answer format and least familiar with extended response and performance assessment formats. This is a particularly important result as the TIMSS designers placed great emphasis on the use of extended response and performance assessment formats.

    How may the use of an abstract picture language affect student learning of energy and change
    Fry, Margaret C. ( 2002)
    The teaching of `Energy' as a topic in school science has often been found in the professional and research literature to be incoherent and scientifically inconsistent. Boohan and Ogborn's `Energy and change' booklets are an attempt to outline a new way for teachers in junior science classes to talk about processes that drive everyday changes from the weather to a car moving. They have sought, around the central idea that change is caused by differences, to use easy language and find coherent ways to describe thermodynamic ideas. They developed a set of abstract pictures to make these ideas intelligible. In this phenomenological classroom-based study the experiences afforded two Year 8 classes and their teachers in the same school in Melbourne by the use of Boohan and Ogborn's abstract picture language are investigated. One teacher took a didactic/empirical approach. He taught from his architectonic conceptual map of energy and followed the standard textbook development of forms of energy punctuated by the recommended experiments and teacher demonstrations to illustrate various changes in form. The abstract pictures were used principally in discussion as summative and interrogative tools towards a clarification of the teacher's conceptual overview. The other teacher took a co-constructive experiential approach. She did not use a class text. The Boohan and Ogborn materials were used as gestural tools in the sense of presenting the gist of the embodied understanding- purposes and meaning- of teacher and students. There were some teacher demonstrations but no practical work. The picture language icons functioned as mediating tools in class conversations towards a perception not that certain predefined teacher concepts had been attained but rather individuals had attained confidence to go on from that juncture. The students' responses to the picture language, in class interaction and group interviews, revealed major similarities across these teaching approaches. Many saw the abstract picture language to be a powerful and economic representational or iconic device that afforded them a means of engaging their own embodied socio-cultural understanding of energy and change phenomena. Some were confused by the purpose and meaning inscribed in the icons. Both teachers felt professionally challenged in the employment of the materials and only partly satisfied by their different enactments. Both were engaged and curious about the intellectual, sensational and aesthetic dimensions of their and their students' experience.

    The Public understanding of techno-science in a rural community: culture & agency
    Campbell, Alasdair C. ( 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.

    Researching teacher agency in primary school science: a discursive psychological approach
    Arnold, Jennifer Lynne ( 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.
