An Analysis of the Perceived Impact of Lesson Study on Improving Secondary School STEM Teacher Effectiveness

The purpose of this study was to determine the extent to which participating in lesson study was perceived to have an impact on teacher effectiveness. Secondary STEM graduates who come into education need a model of collaborative reflective practice for continuous improvement. Lesson study is one possible model of professional learning that is both reflective and collaborative (Sims & Walsh, 2009, p. 731). The cyclical nature of lesson study makes it a natural fit for continuous improvement. Yet, little research into the effectiveness of lesson study as a tool for new teacher preparation or for middle and high school teachers exists. As part of the University of Central Florida\u27s RTP3 program, resident teachers from three school districts participated in lesson study. Their reflections on participating in lesson study were analyzed and interviews with designees from each school district were conducted. The resident teachers\u27 reflections and the interviews with partner school district designees were analyzed using the constant comparison method (Parry, 2004). The reflections were closely examined for trends and patterns, and as commonalities emerged, they led to the findings of this study. After review of the school district lesson study models, they were confirmed and explored during the interviews with school district designees. Analysis showed lesson study was perceived to be beneficial by the resident teachers and two of the three school district designees described positive effects gained from participating in lesson study through RTP3. The literature review and the results of this study demonstrate that lesson study is a valuable tool for professional learning in both novice and veteran teachers. Themes frequently observed in lesson study reflections included increased focus on students, the value found in collaboration, and a desire to participate on future lesson study teams. Teachers, teacher preparation programs, and school administrators should consider the benefits of participating in lesson study and attempt to develop a plan to include this method of professional learning in their school or teacher preparation program
