|Abstract:||Recent studies have shown benefits of problem-solving prior to instruction. However, it is unclear whether these benefits are based on the cognitive processes related to the problem-solving activity prior to instruction or originate from comparing and contrasting students' solutions to the canonical solution during subsequent instruction. To separate these effects, we conducted a quasi-experimental study with 240 students varying the two factors timing of instruction (problem-solving prior to instruction versus instruction prior to problem- solving) and form of instruction (standard instruction versus instruction that compares and contrasts typical student solutions). Our results indicate that comparing and contrasting typical student solutions is a prerequisite for the effectiveness of problem-solving prior to instruction. Problem-solving prior to instruction combined with instruction where student solutions were compared and contrasted to the canonical solution outperformed all other conditions. Problem-solving prior to standard instruction was no more effective than standard instruction prior to problem-solving.|
