We examined college students' procrastination when studying for weekly in-class quizzes. Two schedules of online practice quiz delivery were compared using a multiple baseline design. When online study material was made available noncontingently, students usually procrastinated. When access to additional study material was contingent on completing previous study material, studying was more evenly distributed. Overall, the mean gain in percentage correct scores on weekly in-class quizzes relative to pretests was greater during contingent access than during noncontingent access conditions.
我们研究了大学生在准备每周课堂测验时的拖延行为。使用多基线设计比较了两种在线练习测验交付时间表。当在线学习材料非条件地提供时,学生通常会拖延。当访问额外的学习材料取决于完成先前的学习材料时,学习的分布就更加均匀。总的来说,与前测相比,在有条件访问时每周课堂测验的正确百分比的平均增益大于无条件访问时的情况。
