Curriculum-based professional development on science instruction

This intervention is a year-long professional development program for ninth-grade science teachers that combines comprehensive instructional materials with focused training. The program includes seven days of instruction distributed across four events: a four-day summer institute followed by three follow-up events throughout the school year. The professional development focuses on introducing teachers to the physical and philosophical components of the instructional materials, strengthening their content background, and developing key instructional strategies essential to effective, high-fidelity use of the materials. Teachers implement the instructional materials with their students throughout the school year while receiving ongoing professional development support.
