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.

ItemClassroom management of cooperative learning : a research study of two teaching strategies( 1996)This study sought to contribute to an understanding of the social context of instruction in science classes particularly to group organisation and dialogical processes. This study investigated how two role management strategies (Strategy 1 and Strategy 2) affected communication particularly Conceptualisation in all female, all-male and mixed gender groups in three parallel Year 8 science classes from one school. It also investigated the attitudes of the female and male students towards group work, the two role management strategies and gender. There were two treatment classes and one control class. Each treatment class was observed over an eight week period under each role management treatment. For the eight week period, the control class was managed in a way considered more typical of a traditional science class (No Role Strategy). A randomly selected all-female, all-male and mixed gender group from each class was tested after each treatment phase. The test problem was a practical problem requiring each group to devise and carry out a solution for the test problem. During the testing sessions each group was audio and video taped. The level of Conceptualisation was measured by coded transcriptions of group utterances during the problem solving task. At a time after the final testing session, students in the two treatment classes were administered a Student Group Work Questionnaire to determine their attitudes towards group work, the role management strategies and gender, and, to determine their behaviour in relation to each role management strategy. A statistically significant difference was found between Strategies (No Role Strategy, Strategy 1 and Strategy 2) for the frequency of Conceptualisation utterances. Further analysis revealed a statistically significant difference between No Role Strategy and Strategy 1, and, a significant difference between No Role Strategy and Strategy 2. No statistically significant difference was found between Strategy 1 and Strategy 2. No statistically significant difference was found between Gender groups (All-female, all-male and mixed gender groups) and Phases (Phase 1 and Phase 2) for the frequency of Conceptualisation utterances. Students who received instruction with the role management strategies tended to work better as a team than students who received instruction with only No Role Strategy.

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.

ItemFrom I can't and I don't to I can and I want to : a study in teaching and learning( 1998)In recent years, the teaching and learning of science in primary schools has been a major concern within professional sectors and at all levels of education. This study reveals teachers' responses and personal growth within a long term professional development program. Through an analysis of workshop session transcripts the researcher identifies a range of meanings made by the participant primary teachers about the teaching and learning of science in their classrooms. The findings indicate that positive changes in the teachers' views of themselves as learners of science takes place when teachers and tertiary teacher educators work together in long term collaborative inquiry. A further outcome is that the teachers develop new confidence and abilities which inform their classroom practice.

ItemThe effects of self-pacing and achievement grouping on student learning in middle school science( 1999)By year 10 in a non-selective school, where Science is compulsory, there is a wide spectrum of individual differences in mixed-ability Science classes. Traditional teaching by whole-class instruction usually does not permit the matching of curriculum to individual students' needs. To trial an alternative approach, I designed a five-week intervention. The students in small self-paced groups, followed a sequence of tasks, some of which involved a choice of the level of difficulty. The teacher became the facilitator. It was hoped that if students were grouped by achievement level, they would be able to work at a level and pace appropriate to their learning needs. Because I was interested in the students' cognitive and affective experiences of this intervention, I chose qualitative methods of research, using two case studies, a group of high achievers and a group of average achievers. I also studied how one solo-learner adapted to his group. I found that, unlike the high achievers, the average achievers enjoyed science classes more than usual, became more involved in their learning, and achieved a higher standard than normal. Several factors to explain these differences emerge from the study, including learning strategies, incongruent goals within the groups, and learning styles. The solo-learner's positive experience of the intervention is explained in terms of learning style and goal achievement. Because of the qualitative nature of this study, its findings are contextual and only tentative propositions are made. One such proposition is that the average achievers responded well to group-work because they had the necessary self-regulatory learning strategies to succeed, while the high achievers, previously succeeding with whole-class instruction, had not developed many self-regulatory strategies. This study also raises some issues, such as an assumption that all students, irrespective of their learning style, will learn through group-work.

ItemTwo teaching stategies for managing learning in small groups of different gender composition in science classes( 1996)This study was conducted in three Year 8 classes in one school. It contributes to an understanding of how small groups work in classrooms and the conditions which influence their productivity. In a formal research design two teaching strategies were implemented which managed the status of individuals and the groups. Cognitive and affective learning outcomes were assessed using transcribed group interactions from recorded problem solving sessions. The collaborating teachers of two experimental classes used both management strategies, a low role structure and high role structure over an 8-week teaching period. The third class was the control in which the teachers used no role structure strategy for managing small group learning. Three groups consisting of a boys only group, a girls only group and a mixed gender group from each class were chosen to test achievement using practical investigation problems at the end of each four-week session of implementation of the two strategies. These same students maintained their groupings throughout the eight weeks period of study. Using a combination of audio and video recording, the conversation and behaviour in each group during the problem solving session was made, transcribed and coded. Other support resources used to help interpret the results were: The Learning Preference Scale - Students (LPSS) administered to the students; scripted vignettes taken from student interaction's coded results; informal interview with the teachers, student questionnaire and the author's regular observations of the three classes during the study. From the coded scores on conceptualisation in the group discussion the following propositions were investigated. a) Teaching strategies that manage social and intellectual status differences in classroom groups enhance the achievement of cognitive and affective goals. b) Achievement gains can be linked to patterns of communication in small groups. c) Meaning making is a process of social and cultural conceptualisation which used concepts and skills within small groups. Students prefer cooperative over competitive and/or individualistic learning. d) Gender composition of small groups may influence patterns of communication and hence achievement. More specifically, the non-directional and directional hypotheses tested were: 1. There are no differences between the three strategies (the alternative hypothesis was that active role management treatment will be superior to the no role management). 2. There are no differences between the three gender groups (the alternative hypothesis was that the all boys group will be superior to the all girls group and the mixed gender group). 3. There are no differences between the two treatment phases groups (the alternative hypothesis was that students' performance after phase 2 will be superior to students' performance after phase 1 of the study). While no statistically significant results were found the trends in the data have been generally interpreted as consistent with hypotheses based on the published literature.

ItemChild science to teacher science: a comparison of conceptual transition in the nature of light and the particle theory( 1992)Child Science caught the imagination of science educators in the early 1980's. Since that time, much work has gone into the investigation of Child Science and the concept is now well recognised throughout the world. This study investigates the nature of Child Science and Teacher Science as it relates to two specific concept areas in science - that is, the concepts of Light and the Particle Theory. Students in Victorian schools at Year levels 5 & 9 were compared, as was a gender comparison made for each of the two concepts. Students were first categorised as operating from a Child Science or Teacher Science framework and their subsequent answers to three open-ended questions in the concept areas were examined. The study shows that there is a clear progression towards the embracing of Teacher Science at the Year 9 level, but that the transition is by no means complete for all students. The transition to Teacher Science for the Particle Theory is more dichotomous than for the Light Theory, which has a strong transitional phase. For both concept areas, girls pass through a stronger transitional phase, whereas boys tend to progress more rapidly to the use of Teacher Science. Girls also tend to answer questions relating to these concepts in the ways teachers might expect, whereas boys were more inclined to answer in a way that made little or no sense from a teacher's perspective or did not answer the question at all. The implications for the classroom teacher are considered in light of these findings. How might these strongly held Child Science views be refined, developed or replaced; and the need for recognition by teachers that the teacher needs to provide a suitable transitional framework that promotes intellectual security and a mechanism that will encourage the replacement of the Child Science perceptions with more elaborate, scientifically accepted perceptions.

ItemTeachers' evocation of and response to children's questions in primary science( 1996)Recently some writers have advocated a reorganisation of primary science teaching based on children's questions as an extension of an inquiry based and constructivist approach to teaching and learning. This study was designed to add to recent findings on the role and place of evoking and responding to children's questions in primary science. A case study approach was used to investigate aspects of classroom interactions. Specifically, this study gathered and analysed data on the role and value of a teaching sequence known as the Interactive Teaching Approach as it was used to elicit children's questions as the basis for implementation of science curriculum units by teachers and the associated development of children's questioning skills together with the issues and difficulties which arose for the teachers as they used the approach. Results suggested that, when encouraged, children readily asked questions and asked a range of question types. However, the data gathered also explicated a number of key issues and difficulties which arose for the teachers involved. Their comments suggested that extended professional development will be necessary to implement science curriculum units with an Interactive Teaching Approach. The findings were interpreted and discussed in relation to a suggested model for the development of children as effective questioners, a framework for making sense of children's questions and, as there was some evidence for a change in the nature of children's questions as a topic is taught, a proposed model of stages of development of a curriculum unit and children's questioning skills. They were also linked to future professional development for primary teachers. The teachers in this study found the information gathered to be valuable for them as they planned their teaching and learning strategies and their involvement in the research advanced their professional development as science teachers in primary schools.

ItemThe Australian Science Education Project: a case study in curriculum implementation( 1991)The Australian Science Education Project (ASEP) was developed between 1969-74 as Australia's first national curriculum project. ASEP was designed to introduce major changes for years 7-10 science in materials, content and assigned roles for teachers and students. While initial sales of the ASEP materials were excellent in Victoria the extent of implementation was low. This study examines reasons for this unsuccessful implementation from a user (i.e. teacher and schools) perspective. Determinants or causes of the extent of implementation relating to the nature of the ASEP materials, the strategies for implementation and the nature of teaching and schools are examined. The fundamental cause of the low level of implementation in Victoria is related to the development of the ASEP materials from a 'technological' perspective with limited input by classroom teachers. The materials developed in this way could only be successful if the implementation strategies included extensive in-service and curriculum support for science teachers and this did not happen in Victoria. Based on Havelock's 'Problem Solver' perspective of curriculum change a model for effective implementation is proposed which incorporates a 'user' perspective and the notion of mutual adaptation between the innovation and the user system.

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.
