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.

ItemOpening the door of the 6th form chemistry laboratory: a study of professional collaboration between a science teacher and an English as a second language (ESL) teacher in senior chemistry( 1997)True professional teacher collaboration has been limited by the institutional roles which are constructed for us and through which we view ourselves. This thesis is a narrative case study of teacher collaboration for the purpose of addressing the language learning needs of English as a Second Language students in Year 12 Chemistry classes. It explores the issues involved in the professional working relationship through the voices of a Science teacher and an ESL teacher over a two year period. This was done through transcripts of classroom teaching, analysis of teaching and learning materials produced, interviews and reflective journal writing. The study looked at the groundwork which took place to establish a school climate conducive to the collaboration in terms of the Habermasian interests; technical, practical and emancipatory. The emancipatory nature of the collaboration is explained in terms of the repositioning of the teachers with regard to each other, the students, the scientific and linguistic subject matter. By exercising power in their respective fields the collaborating teachers achieved a professional parity which allowed them to reflect on their practice and move beyond the static and ritualised institutional roles of a Chemistry and an ESL teacher. Through the interaction they established language as legitimate content in the science classroom and together explored new practices afforded by the adoption of a social constructivist epistemology. This research points to the emergence of a new more empowering professional development role for ESL teachers in the future. At the heart of this collaboration is a commitment to conversations about issues of fundamental importance in classroom practice which reconcile boundaries of differing departmental cultures and discourses.
