E-learning is widely used in undergraduate medical education and often in blended learning settings for students learning at home. This study should assess the educative value of e-learning tools in orthopedics and traumatology when used under "field" conditions, in comparison with a controlled laboratory-like setting.
Medical students were invited for their voluntary online participation in an uncontrolled study (UCS). They were randomly exposed to digital book chapters or podcasts on four different orthopedic diseases, and then filled in pre-/post-tests and evaluations. Test results indicating insufficient study participation were not included in the subsequent analysis. Results in a gain of knowledge and student's satisfaction were compared to existing data of a randomized controlled trial with the same tools in a laboratory environment (RCT).
Among 84 included UCS students and 130 RCT students, podcast learners showed a significantly higher gain of knowledge compared to text learners independent of the learning setting (UCS p<0.011; RCT p<0.001). There were no significant differences in the gain of knowledge for the two different learning tools when comparing each the UCS and RCT settings. Evaluations showed positive ratings for both tools, while podcasts were on the average rated higher than texts were. Significantly more UCS participants (n=46) compared to the RCT (n=34) showed signs of disengagement with the study (p<0.05).
The findings suggest that it is possible to achieve a similar gain of knowledge with e-learning tools in uncontrolled settings and in RCTs. The role of e-learning materials in voluntary and formative learning settings is of value and should be explored in future studies.

电子学习在本科医学教育中被广泛应用,并且经常用于学生在家学习的混合学习环境中。本研究旨在评估在“实地”条件下使用电子学习工具进行骨科和创伤学教育的价值,并与类似实验室的受控环境进行比较。
邀请医学生自愿在线参与一项非对照研究(UCS)。他们被随机暴露于关于四种不同骨科疾病的数字书籍章节或播客,然后填写课前/课后测试及评估。表明学习参与不足的测试结果不纳入后续分析。将知识增益和学生满意度的结果与在实验室环境中使用相同工具的随机对照试验(RCT)的现有数据进行比较。
在84名纳入的UCS学生和130名RCT学生中,无论学习环境如何,播客学习者的知识增益均显著高于文本学习者(UCS p<0.011;RCT p<0.001)。比较UCS和RCT设置时,两种不同学习工具的知识增益没有显著差异。评估显示对两种工具的评价均为积极,而播客的平均评分高于文本。与RCT(n = 34)相比,UCS中有更多参与者(n = 46)表现出脱离研究的迹象(p<0.05)。
研究结果表明,在非受控环境和随机对照试验中使用电子学习工具可以获得相似的知识增益。电子学习材料在自愿和形成性学习环境中的作用具有价值,应在未来研究中进行探索。
