The efficiency of worked examples compared to erroneous examples, tutored problem solving, and problem solving in computer-based learning environments
作者：
Highlights：
• We compared high and low assistance instructional materials, i.e., worked examples, erroneous examples, tutored problems, and problems.
• In two multi-session classroom experiments, worked examples proved to be the most efficient.
• Study time reductions with worked examples were between 46 and 69% compared to the other instructional approaches.
