Galileo and pendulum motion: A case for history and philosophy in the science classroom

There are encouraging signs that the history and philosophy of science are becoming more important in the teaching of science and in the preparation of science teachers. This tendency is supported here by looking at the widespread treatment of Galileo's account of pendulum motion in science texts and classrooms, indicating that it is a less than adequate account of the historical facts, and suggesting that the teaching of this commonplace topic can be considerably enhanced if science teachers have some familiarity with basic research in the history and philosophy of science.     

Enhancing outcomes and reducing inhibitors to the engagement of students and staff in learning and teaching partnerships: implications for academic development

A growing body of literature on students as partners in learning and teaching offers evidence on which academic developers can draw when supporting, advocating for, or engaging in partnerships. We extend a previous systematic review of the partnership literature by presenting an analysis and discussion of the positive and negative outcomes of partnership, and the inhibitors to partnership. Implications include the importance of academic developers supporting: the relational processes of partnership; institutional or structural change to address resistance; and the potential of partnership to make institutions more equitable and empowering spaces.     

Reflective and Reflexive Practice in Initial Teacher Education: a critical case study

Abstract

This article outlines approaches that are being adopted to encourage students training to be teachers on a Postgraduate Certificate of Education (PGCE) course to reflect upon their teaching. It takes the form of a special case designed to nurture good practice in Teacher Education. Applications for those working in higher education are discussed. A distinction has been made between reflection and reflexivity (Ashmore, 1989; Bourdieu & Wacquant, 1992). It was found that engaging students in reflexivity can have benefits in terms of classroom effectiveness and reflective writing can play an enhancing role in this process. It was found that many students were judged to have exhibited reflexivity in their teaching and in their written work. Ways in which the emphasis on reflective practice has led to the development of classroom skills were identified.     

A study of changes in middle school teachers' understanding of selected ideas in science as a function of an in-service program focusing on student preconceptions

This article examines the impact of a specially designed in-service model on teacher understanding of selected science concepts. The underlying idea of the model is to get teachers to restructure their own understanding of a selected science topic by having them study the structure and evolution of their students' ideas on the same topic. Concepts on topics from the life, earth, and physical sciences served as the content focus and middle school Grades 4–9 served as the context for this study. The in-service experience constituting the main treatment in the study occurred in three distinct phases. In the initial phase, participating teachers interviewed several of their own students to find out what kinds of preconceptions students had about a particular topic. The teachers used concept mapping strategies learned in the in-service to facilitate the interviews. Next the teachers teamed with other teachers with similar topic interests and a science expert to evaluate and explore the scientific merit of the student conceptual frameworks and to develop instructional units, including a summative assessment during a summer workshop. Finally, the student ideas were further evaluated and explored as the teachers taught the topics in their classrooms during the fall term. Concept maps were used to study changes in teacher understanding across the phases of the in-service in a repeated-measures design. Analysis of the maps showed significant growth in the number of valid propositions expressed by teachers between the initial and final mappings in all topic groups. But in half of the groups, this long-term growth was interrupted by a noticeable decline in the number of valid propositions expressed. In addition, analysis of individual teacher maps showed distinctive patterns of initial invalid conceptions being replaced by new invalid conceptions in later mappings. The combination of net growth of valid propositions and the patterns of evolving invalid conceptions is discussed in constructivist terms.
