The relationship of science teachers' beliefs and practices

The relationships between constructivist and Science-Technology-Society (STS) teaching practices and teachers beliefs are the focus of this dissertation. This study is founded on the premise that individual teacher's beliefs are strong indicators of their instructional choices and teaching habits. The basic research premise is: the more complete and complex the individuals' belief structure about constructivist and STS teaching, the more expert and consistent the teacher is in the complementary constructivist teaching practices.; This triangulation study used quantitative and qualitative methods. Three instruments were used: the Science Classroom Observation Rubric and Teaching Practices Assessment Inventory, from the Expert Science Teacher Educational Evaluation Model (ESTEEM), and the Science Teacher Beliefs About the Learning Environment Rubric (developed by the author). The results yielded significant multiple regression analysis regarding the relationships between beliefs and practices in constructivist/STS science teaching not documented elsewhere. Statistically significant factors contributing to expertise included the value teachers placed on their students as individuals whose ideas and contributions to the class are important, teachers' commitment to work as partners with students in the learning environment, and the importance of context, i.e., instruction which is personally relevant and meaningful. No differences were found related to gender or total years of teaching experience.; A cross-case methodology was used to explore data from open-ended interviews and for examination of teachers' written comments regarding their interactions with students in the learning environment. Expertise was also shown to be linked to teachers with a commitment to life-long learning and to years of participation/leadership by teachers in state and national reform movements. Qualitative data corroborated these findings, providing a rich and authentic background to the correlational results and analysis of key demographics. Most noteworthy were teachers' comments regarding partnerships with their students and the importance of instructional relevancy.
