The Inquiry Design Model (IDM) is a distinctive approach to creating curriculum and instructional materials that honors teachers’ knowledge and expertise, avoids overprescription, and focuses on the main elements of the instructional design process as envisioned in the Inquiry Arc of the College, Career, and Civic Life (C3) Framework for State Social Studies Standards (2013) [LINK]. Unique to the IDM is the blueprint, a one-page representation of the questions, tasks, and sources that define a curricular inquiry.
