Competency-oriented Learning by Teaching is as effective as Mastery Learning provided by Cognitive Tutor

抄録

The effect of Learning by Teaching and learning by being tutored was compared for learning linear equations. Three versions of an online learning environment were created: (1) APLUS for Learning by Teaching, (2) AplusTutor that is a cognitive tutor without problem selection adaptation, and (3) CogTutor+ that is equivalent to the traditional cognitive tutor. A randomized controlled study was conducted in two public schools with 184 7th and 8th grade students. The results showed (i) students’ in the AplusTutor condition finished the quiz quicker than students in the APLUS condition, and (ii) there was a notable difference between Learning by Teaching and learning by being tutored in the “effort” students made.
