5E+IA instructional model

The 5E instructional model was originally developed by Rodger Bybee at BSCS Science Learning in 1987. Over the past three decades, the 5E model has been implemented widely for science instruction, refined continuously based on research and classroom experience, and validated by research assessing its effectiveness.

We built our entire curriculum around the research-based 5E lesson model, then added our own components (Intervention and Acceleration) to ensure ample support for every student.

In this guide we will cover:

• Underlying principles of 5E
• Elements of the BSCS 5E instructional model
• The STEMscopes 5E+IA lesson model
