About This MicroSim¶
Three overlapping circles represent the three basic psychological needs from Self-Determination Theory: Autonomy (blue), Competence (green), and Relatedness (orange). The seven regions -- three individual needs, three pairwise overlaps, and the central three-way overlap -- each reveal different insights about learner motivation.
Hover any region to see what learners experience when that combination of needs is met, along with concrete textbook design decisions that serve it. The center, where all three overlap, represents full intrinsic motivation -- the target state for every chapter.
Learning Objective (Analyze): Given a chapter excerpt, identify which of the three SDT needs it supports and which it neglects.
