课程设计假设成功完成先决条件课程将对学生在需要先决条件的课程中的表现产生积极影响。我们最近有机会测试这个假设，关于完成有机化学先决条件和性能之间的关系，在介绍生物化学。我们没有发现统计学上的显着差异，平均生化成绩或年级分布的学生有或没有有机化学的先决条件。然而，在生物化学之前没有完成有机化学先决条件的学生比完成先决条件的学生更有可能退出课程。相反，在生物化学和完成有机化学的性能之间缺乏相关性，我们观察到一个强大的，非常显着的累积GPA和生物化学等级之间的正相关关系。我们的数据表明，排除学生没有有机化学将有较少的积极影响，学生在生物化学的成功比将提供额外的支持，所有学生谁注册在生物化学与累计GPA低于2.5。
Curriculum design assumes that successful completion of prerequisite courses will have a positive impact on student performance in courses that require the prerequisite. We recently had the opportunity to test this assumption concerning the relationship between completion of the organic chemistry prerequisite and performance in introductory biochemistry. We found no statistically significant differences between average biochemistry grades or grade distribution among students with or without the organic chemistry prerequisite. However, students who had not completed the organic chemistry prerequisite before biochemistry were more likely to withdraw from the course than those who had completed the prerequisite. In contrast to the lack of correlation between performance in biochemistry and completion of organic chemistry, we observed a strong, highly significant positive relationship between cumulative GPA and the biochemistry grade. Our data suggest that excluding students without organic chemistry would have less positive impact on student success in biochemistry than would providing additional support for all students who enroll in biochemistry with a cumulative GPA below 2.5.
