This document discusses formative evaluations, which are used to strengthen the learning process. Formative evaluations are an essential part of the learning process and provide immediate feedback. They should be conducted throughout the course development process. Effective formative evaluations include designing instructional strategies, conducting one-on-one and small group evaluations with learners, and field trials to test materials in real-world contexts. Specialist reviews are also important. The goal of formative evaluations is to improve both teaching materials and learner understanding through an iterative process of analysis, data collection, and revision.
