This record of study (ROS) explores the perceptions of three high school biology teachers who implemented a form of the Japanese originated Lesson Study Professional Development (LS PD) model. Additionally, this ROS reports on the perceptions of the internal stakeholders with regard to the model's viability as a potential solution to a proposed problem of practice where there was a lack of quality professional development for secondary biology teachers. The audience of internal stakeholders includes district administrators, high school teachers, and science teachers from the elementary and middle school grade levels. Participants of this study collaboratively explored the problem of practice in the fall semester of 2015, then implemented the LS PD model in the spring semester. The participants completed three cycles of LS that focused on collaboratively designing research-based lessons, teaching the lessons with peer observations, revising and re-teaching the lessons with peer observations, and reflecting on the participants' growth experiences. Four research questions were addressed: (a) What are the perceptions of the participants in regard to their own professional growth as a result of participating in the LS initiative? (b) What improvements to the LS PD model might facilitate future implementation? and (c) What are the perceptions of the LS dissemination audience toward LS as a viable solution to a lack of quality PD for secondary biology teachers? Results of the study suggested that LS PD may be a viable solution to the proposed problem of practice where there is a lack of quality professional development for secondary biology teachers. Long-term implications posit that LS PD can be adapted and scaled up to benefit all content areas and grade levels.
