- The educational literature suggests that the success of professional development is contingent upon both a professional developer’s presentation of the curriculum and his/her comprehension of the complex interactions that occur between instructor and the adult learner. While these suggestions appear forthright and logical, very little research has been conducted to demarcate how professional development approaches defined by these notions impact teacher knowledge. This study investigates the effects of scientist-delivered teacher professional development on teachers’ understanding of the nature of science. Using a mixed-method comparative case study, my goal was to build theory focusing specifically on two dimensions of professional development: the pedagogical approaches used by the scientist-instructors and their views/treatment of teachers as professionals or as technicians. Seven credit-bearing summer courses from multiple scientific disciplines were studied, and each course shared a number of important features (duration, general format, teacher recruitment and admission, location, number of participants, etc.); consequently, they comprise a unique dataset for comparative research on science teacher professional development. A wide variety of data collection approaches were used, including interviews, questionnaires, a VNOS instrument, and systematic classroom observation by ten trained observers (each course was continuously observed by at least two observers). Analysis shows that teachers were more likely to experience change in their views about the nature of science in courses in which they were treated as professionals, compared to courses in which they were treated as technicians. It also shows that syllabi and participant reports tend to overstate the use of inquiry methods when reviewed in the light of close classroom observation. By recognizing and defining professional development contexts that build teachers’ knowledge, this study suggests how university-based professional development for science educators can be improved, helping to actualize the collaborative relationships that need to exist between staff developers and discipline specialists. In conclusion, I use the findings from this study to expand the current literature and suggest how improved university-based professional development contexts can be created.
