Abstract

OBJECTIVE

To compare student outcomes between concurrent online and on-campus sections of an introductory biostatistics course offered at a United States school of public health in 2005.

METHODS

Enrolled students (95 online, 92 on-campus) were invited to participate in a confidential online survey. The course outcomes were compared between the two sections adjusting for differences in student characteristics.

RESULTS

Seventy-two online (76%) and 66 (72%) on-campus enrollees participated. Unadjusted final exam scores for the online and on-campus sections were respectively 85.1 and 86.3 (p=0.50) in term 1, and 87.8 and 86.8 (p=0.51) in term 2. After adjustment for student characteristics, the average difference in scores between the two sections was -1.5 (95% CI: -5.4, 2.5) in term 1, and 0.8 (95% CI: -2.7, 4.3) in term 2.

CONCLUSIONS

The results demonstrate that online and on-campus course formats of an introductory biostatistics course in a graduate school of public health can achieve similar student outcomes.

摘要

目的

比较 2005 年美国一所公共卫生学院的一门基础生物统计学课程的在线同步与面授课程的学生学习成果。

方法

邀请注册学生（线上 95 人，面授 92 人）参与一项保密的在线调查。调整学生特征差异后，比较两个课程的学习成果。

结果

分别有 72 名（76%）线上注册者和 66 名（72%）面授注册者参与。第一学期，线上和线下课程的期末考试成绩分别为 85.1 分和 86.3 分（p=0.50），第二学期分别为 87.8 分和 86.8 分（p=0.51）。在调整学生特征后，两部分的平均分数差异分别为第一学期为-1.5（95%置信区间：-5.4，2.5），第二学期为 0.8（95%置信区间：-2.7，4.3）。
