This document describes the process of formative evaluation of instructional materials and presentations. It involves iterative cycles of collecting feedback, analyzing data, and revising materials to improve unclear or ineffective components. The first cycle involves one-to-one evaluations with target learners to identify gross errors in message clarity, links to prior knowledge, procedures, and motivational value. Learners provide feedback through interactive interviews to help designers understand what is wrong and why. The goal is to refine materials until they are clear, impactful, and feasible for the intended learning context.
