This study investigated the influence of five problem characteristics on students' achievement-related classroom behaviors and academic achievement. Data from 5,949 polytechnic students in PBL curricula across 170 courses were analyzed by means of path analysis. The five problem characteristics were: (1) problem clarity, (2) problem familiarity, (3) the extent to which the problem stimulated group discussion, (4) self-study, and (5) identification of learning goals. The results showed that problem clarity led to more group discussion, identification of learning goals, and self-study than problem familiarity. On the other hand, problem familiarity had a stronger and direct impact on academic achievement.
本研究调查了五个问题特征对学生与成就相关的课堂行为和学业成绩的影响。通过路径分析，对来自 170 门课程的 5949 名理工学院学生的数据进行了分析。这五个问题特征是：（1）问题清晰度，（2）问题熟悉度，（3）问题激发小组讨论的程度，（4）自学，以及（5）学习目标的确定。结果表明，与问题熟悉度相比，问题清晰度导致了更多的小组讨论、学习目标的确定和自学。另一方面，问题熟悉度对学业成绩有更强和更直接的影响。
