摘要

This study examined both the changes that elementary school teachers experienced when they implemented a reform-based science curriculum and the impact of professional development on this transformation. The research involved a case study of three purposefully selected teachers implementing the Linking Food and the Environment (LIFE) program during the 2002--2003 school year. The LIFE program is a curriculum designed to enhance science literacy among learners from high poverty urban environments.; While the study was grounded in the tradition of critical theory (Carspecken, 1996), the theoretical perspective of hermeneutic phenomenology (van Manen, 1990) guided data collection and analysis. Extensive observations of the teachers were made in order to capture and record the teacher change phenomenon. Data were recorded by means of field notes, audio and videotapes, semi-structured interviews, classroom observations, and video Stimulated Recall (SR) interviews.; Emerging themes relating to teacher change, knowledge interests, constructivist pedagogy, and professional development illustrated how teachers grapple with various aspects of implementing a reform-based science curriculum. The teachers in this study were similar to those in earlier investigations, which found that sustained professional development programs involving mentoring and constant reflection enable elementary science teachers to change their instructional strategies from the technical-realist orientation towards the practical-hermeneutic and emancipatory-liberatory orientations. The study has implications for science curriculum developers and designers of professional development programs.
