Abstract ABSTRACT It is argued that teachers must experience inquiry in order to be able to translate it to their classrooms. The National Science Foundation’s (NSF’s) Research Experiences for Teachers (RETs) offer promising programs, yet scant empirical support documents the effectiveness of these programs. In this study, ten experienced, secondary science teachers were followed back to the classroom after a five-week, marine ecology RET, addressing the questions: How do teachers’ conceptions and enactment of classroom inquiry change after the program?; What are the program’s goals?; What accounts for these differences?; and What do these findings imply for future RETs? Data collected includes pre and post program questionnaires, audiotapes and videotapes of pre and post program teaching, post program STIR instrument responses, interviews, and field notes. The study found that an extensive, reflective program model, conducted by scientists who are teacher-centered, successfully conveyed the program model of inquiry. Post program, teachers’ conceptions of inquiry were more student centered, focused less on assessment and classroom management and more on authentic content, questions, and presentations, and incorporated program language. Question patterns during enactment shifted to fewer teacher questions, more student questions, and increased higher order questions by students and teachers. More procedural questions indicated role shifts. The STIR instrument fostered understanding of enactment and, with critical incidents analyses, highlighted underlying teacher value structures. Teachers with more theoretical sophistication and who had Rationalistic and Egalitarian value structures applied inquiry throughout their teaching and moved beyond contextual constraints. Implications suggest that those who develop and implement RETs need to be masterful “bridge builders” to help transition teachers and their learning back to the classroom. Reflection holds promise for illuminating teachers’ underlying values and goals and in gaining an understanding of teachers’ enactment. Curriculum materials and theoretical readings can assist teacher change. Assimilation of new knowledge does not necessarily lead to transformation of practices. Rather, this study found that teachers with values and goals that were compatible to the RET, as well as an accompanying high level of theoretical sophistication, moved toward transformational change.
