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.

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.

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.
