This article reports on part of a larger study of how 11‐ and 12‐year‐old students construct knowledge about electricity and magnetism by drawing on aspects of their experiences during the course of a school visit to an interactive science museum and subsequent classroom activities linked to the science museum exhibits. The significance of this study is that it focuses on an aspect of school visits to informal learning centers that has been neglected by researchers in the past, namely the influence of post‐visit activities in the classroom on subsequent learning and knowledge construction. This study provides evidence that the integrated series of post‐visit activities resulted in students constructing and reconstructing their personal knowledge of science concepts and principles represented in the science museum exhibits, sometimes toward the accepted scientific understanding and sometimes in different and surprising ways. A descriptive interpretive approach was adopted, with principal data sources comprising student‐generated concept maps and semistructured interviews at three stages of the study. Findings demonstrate the interrelationships between learning that occurs at school, home, and in informal learning settings. The study also underscores for classroom teachers and staff of science museums and similar centers the importance of planning pre‐ and post‐visit activities. The importance of this planning is not only to support the development of scientific conceptions, but also to detect and respond to alternative conceptions that may be produced or strengthened during a visit to an informal learning center. © 2000 John Wiley & Sons, Inc.

Research into learning in informal settings such as museums has been in a formative state during the past decade, and much of that research has been descriptive and lacking a theory base. In this article, it is proposed that the human constructivist view of learning can guide research and assist the interpretation of research data because it recognizes an individual's prior knowledge and active involvement in knowledge construction during a museum visit. This proposal is supported by reference to the findings of a previously reported interpretive case study, which included concept mapping and semistructured interviews, of the knowledge transformations of three Year 7 students who had participated in a class visit to a science museum and associated postvisit activities. The findings from that study are shown in this report to be consistent with the human constructivist view of learning in that for all three students, learning was found to be at times incremental and at other times to involve substantial restructuring of knowledge. Thus, we regard that the human constructivist view of learning has much merit and utility for researchers investigating the development of knowledge and understanding emergent from experiences in informal settings. The theoretical and practical implications of these findings for teachers and staff of museums and similar institutions are also discussed. ß

This paper describes the conduct of, and acquired understandings from, a study designed to promote the professional growth of a group of beginning primary school teachers through participatory action research. The beginning teachers collaborated with university academic staff during the design and conduct of the study. A key component of the study was the formation of action research cells of participating teachers with each group focusing on particular aspects of teaching, for example, assessment, catering for gifted and talented students, and inclusivity in the classroom teaching program. The overall findings from the study, from the view of the university researchers, are presented and reflected upon in this paper. The implications of using action research for the professional growth of beginning teachers are also discussed.1
