STeLLA (Science Teachers Learning through Lesson Analysis): Improving Student Science Achievement by Enhancing Teacher Ability to Explain Science Concepts, Identify Science Concepts in Student Learning Activities, and Engage Students in Thinking about Science

STeLLA (Science Teachers Learning through Lesson Analysis) is a professional development program for teachers that aims to improve student science achievement by enhancing teachers' ability to explain science concepts, identify science concepts used in student learning activities, and engage students in thinking about science. The program consists of a 2-week summer institute, followed by eight monthly study group sessions during the school year, where teachers learn from postsecondary science faculty and STeLLA professional development leaders, analyze videorecorded lessons, and develop their own science lesson plans.
