Teachers' implementation of reform-oriented instructional strategies in science: Lessons from two professional development programs

Abstract

This dissertation reports findings from two studies that investigated the relationship between professional development and teachers' instructional practices in Science,Technology, Engineering, and Mathematics (STEM). The first program, the Indiana Science Initiative (ISI) focused on K-8 teachers and their use of inquiry-based science instruction in conjunction with curricular modules provided by the ISI program. The second program, Research Goes to School (RGS), focused on high school STEM teachers and their use of problem-based learning (PBL) as they implemented curricular units that they developed themselves at the RGS summer workshop. In-service teachers were recruited from both programs. They were observed teaching their respective curricular materials and interviewed about their experiences in order to investigate the following research questions: 1. How do teachers implement the reform-oriented instructional strategies promoted by their professional development experiences with the ISI or RGS? 2. What are the challenges and supports that influence teachers' use of the reform-oriented instructional strategies promoted by their professional development experiences with the ISI or RGS? To investigate these questions the fidelity of implementation was it was conceptualized by Century, Rudnick, and Freeman (2010) was used as a theoretical framework. The study of the ISI program was conducted during the program's pilot year (2010-11). Five teachers of grades 3 through 6 were recruited from three different schools. Participants were observed as they taught lessons related to the modules and they were interviewed about their experiences. Based on analysis of the data from the observations, using a modified version of the Science Teacher Inquiry Rubric (STIR) (Bodzin & Beerer, 2003), the participants were found to exhibit partial fidelity of implementation to the model of inquiry-based instruction promoted by the ISI. Based on data from the interviews, the participants in this study perceived time for science instruction, limits in their students' abilities and behavior, and their own development as facilitators as challenges to their efforts to implement inquiry-based science instruction. They identified their participation in the ISI pilot, the curricular modules and a science notebook strategy promoted by the ISI as supports for their instruction. Two studies of the RGS program were conducted. The first was a pilot study that was conducted in the academic year following the first RGS summer workshop (2011-12). The second was a collective case study conducted after the second RGS workshop (2012-13). In both studies participants were videotaped as they implemented the PBL units that they had developed at their respective RGS workshops and interviewed about their experiences after they implemented the units. The data from the observations were examined using a rubric developed for the study to examine their use of PBL features. Based on the analysis of the data from the observations, the RGS participants exhibited partial fidelity of implementation to the features of PBL. Analysis of the data from the interviews indicated that participants were aware of features of PBL that they were not able to fully implement. Participants also identified several supports, particularly from the RGS program such as being able to order materials to implement their units, as well as supports that were specific to their teaching contexts. The findings from both the ISI study and RGS collective case study suggest that the professional development programs had some positive if limited influence on teachers' instructional practices. Across the studies, persistent challenges were identified regarding teachers' efforts to meaningfully engage students in practices that would develop their abilities to reason scientifically. Comments from participants in both studies about the supportive role of their respective curricula also lend support to arguments about the role of curriculum materials in achieving science education reform (Powell & Anderson, 2002).
