Asynchronous learning is gaining popularity. Data are limited regarding this learning method in medical students rotating in emergency medicine (EM). In EM, faculty time is limited to give in-person lectures. The authors sought to create an online curriculum that students could utilize as an additional learning modality.
The goal was to evaluate effectiveness, participation, and preference for this mode of learning.
We developed five online, narrated PowerPoint presentations. After orientation, access to the online curriculum was provided to the students, which they could review at their leisure.
One hundred and seven fourth-year medical students participated. They reported the curriculum to be of high quality. Pretest scores were similar for those that viewed all lectures - compliant group (CG) (9.5 [CI 4.8-14.1]) and those that did not view any - non-compliant group (NCG) (9.6 [CI 5.9-13.4]). There was no statistical significant difference in posttest scores between the groups although there was improvement overall: CG 14.6 (CI 6.9-22.1); NCG 11.4 (CI 5.7-17.1). A majority (69.2%) favored inclusion of asynchronous learning, but less than a quarter (22.4%) reported viewing all five modules and more than a third (36.4%) viewed none.
Despite student-expressed preference for an online curriculum, they used the online resource less than expected. This should give pause to educators looking to convert core EM topics to an online format. However, when high-quality online lectures are utilized as a learning tool, this study demonstrates that they had neither a positive nor a negative impact on test scores.
异步学习越来越受欢迎。关于这种学习方法在急诊科轮转医学生中的应用,数据有限。在急诊科,教员进行面对面授课的时间有限。作者试图创建一个在线课程,供学生作为一种额外的学习方式使用。
目标是评估这种学习模式的有效性、参与度和偏好。
我们制作了五个在线的、有旁白的PowerPoint演示文稿。在培训后,向学生提供了在线课程的访问权限,他们可以在闲暇时进行复习。
107名四年级医学生参与其中。他们报告该课程质量很高。观看了所有讲座的学生——依从组(CG)的预测试成绩(9.5 [CI 4.8 - 14.1])与未观看任何讲座的学生——非依从组(NCG)的预测试成绩(9.6 [CI 5.9 - 13.4])相似。尽管总体上有提高,但两组的后测试成绩没有统计学上的显著差异:CG为14.6(CI 6.9 - 22.1);NCG为11.4(CI 5.7 - 17.1)。大多数(69.2%)学生赞成采用异步学习,但不到四分之一(22.4%)的学生报告观看了所有五个模块,超过三分之一(36.4%)的学生一个模块都没看。
尽管学生表示更喜欢在线课程,但他们对在线资源的使用低于预期。这应该让希望将核心急诊科主题转换为在线形式的教育工作者有所思考。然而,当高质量的在线讲座被用作学习工具时,本研究表明它们对考试成绩既没有积极影响也没有消极影响。
