Abstract

Student success and attempts on hundreds of online homework problems housed in a fully interactive online textbook, Material and Energy Balances zyBook, were studied over three cohorts of students (n=284). Auto-graded homework questions with randomized numbers and content can explore proficiency in the course material. Students are allowed to attempt any question as many times as needed, and a median success of 94% was found. Also, students completed thousands of attempts after correctly answering without the incentive to improve grades.

学生成功和尝试自动评分作业跨多组在物质和能量平衡

研究人员对三组学生(n=284)进行了研究，这些学生在完全互动的在线教科书《物质和能量平衡zyBook》中数百道在线作业问题上的成功和尝试情况。使用随机数字和内容的自动评分作业问题可以考察学生对课程材料的熟练程度。学生可以根据需要多次尝试任何问题，平均成功率为94%。此外，学生在正确回答问题后，在没有提高成绩的激励下完成了数千次尝试。
