Science Teachers Learning through Lesson Analysis (STeLLA®)
About the Intervention
STeLLA® is a yearlong professional development program for K-12 teachers that aims to improve students' science achievement by enhancing teachers' science content knowledge and instructional abilities. The program begins with a 2-week summer institute (60 hours) led by postsecondary science faculty and STeLLA® professional development leaders, where teachers develop content knowledge in two science topics, review STeLLA® model lesson plans, learn instructional strategies, and analyze videos of experienced teachers. During the school year, teachers attend eight monthly grade-level study group meetings (30 hours total, 3-4 hours each) where they videorecord their own lessons and collaboratively analyze one another's instruction with guidance from STeLLA® professional development leaders. Teachers receive STeLLA® lesson plans, strategy guides, lesson analysis protocols, videorecordings, transcripts, and online access to their study group's videos.
