Learning by Observing Tutorial Dialogue versus Monologue Collaboratively or Alone


We report on a study with 65 middle-school students who learned about the concept of diffusion through observation. We manipulated two factors: the number of observers, solo vs. dyad, and the type of video students observed, tutorial dialogue vs. monologue. Our findings show that dyad observers learn significantly better than solo observers, and that for certain types of questions, observing dialogue results in better learning gains, as compared to observing monologue.
