MCII’s effect is conditional on the type of learners’ stated obstacle. Course completion outcomes in the first experiment examined by obstacle type and cultural context (n = 9,619). Three obstacle types were identified using natural language processing (latent Dirichlet allocation topic modeling) of learners’ stated obstacles. Error bars represent ±1 SE.
