Establishing TELLme - an online platform for self-directed, formative assessment of knowledge acquisition across an undergraduate medical curriculum.

Purpose: The purpose of this study is to report on the design, implementation, use and evaluation of TELLme, an online platform with annotated multiple-choice questions (MCQs) for formative assessment of knowledge acquisition covering an entire undergraduate medical curriculum.

Materials And Methods: We used the Educational Design Research (EDR) framework to develop TELLme as an online platform with 24/7 access for students in a co-creation process between educators, faculty and students. EDR cycle 1 focused on prototyping, while EDR cycle 2 focused on upscaling, usage analysis and evaluation.
