Comparison of Two Teaching Strategies in Computer-Assisted Instruction. Report No. 2885.
Collins, Allan M.
Three experiments were run using the SCHOLAR CAI (computer assisted instruction) system to teach geography to high school students. The experiments compared a method of teaching derived from analysis of human tutors (Tutorial Mode) vs. a method derived from programed instruction (Block-Test Mode). In the three experiments, Block-Test Mode was systematically converged toward Tutorial Mode in order to pinpoint what aspects of teaching strategy affected student's learning. Tutorial Mode was significantly more effective in the first two experiments, and nonsignificantly effective in the third. The results indicated that the major factor affecting the student's learning was the strategy that tutors use of reviewing the material in greater depth on a second pass. Allowing the students to ask questions, and the tutorial strategy for relating new material to the student's previous knowledge contributed only a small amount to the differences found in the first two experiments.
