Have you heard of the phenomena "curse of knowledge"? I've been a victim of it and I'm sure many educators have as well. Essentially the "curse of knowledge" is a cognitive bias that occurs when an individual or educator, unknowingly assumes that others should have the background to understand something. Once we have known something for so long we forget the difficulties that beginning learners have. We sometimes question why our students just don't get a certain concept because to us it seems so simple!
Novice learners understand what it’s like to learn a new concept as a “novice” and this is where peer instruction may have it's advantages. Although there are limitations to peer instruction, research suggests that this approach, interspersed with mini lectures and within a structured environment, is effective at promoting student engagement, critical thinking, problem solving, knowledge retention etc (Mazur, 2015)..Students often learn from one another and under a student-centered approach, educators should be less of the sage on the stage and more of the guide on the side
