What are Conceptests? Multiple-choice questions used to: –Explore depth of student understanding –Provide timely feedback for students and instructors –Facilitate peer instruction and just-in-time teaching –Utilize Bloom’s Learning Domains Knowledge Understanding Application Analysis Synthesis Evaluation
