The MBI Unit Development Template provides a structured yet flexible framework that helps educators from preservice to experienced teachers design or adapt phenomenon-driven inquiry units. It guides decisions about selecting anchoring phenomena, eliciting and tracking student ideas, structuring investigations, and supporting model development, with embedded links to detailed guidance and examples for each stage. The template also connects to targeted resources on key practices such as modeling, constructing explanations, and facilitating productive discourse, enabling teachers to design dynamic, student-centered units that engage students in scientific inquiry.
