In physiological education, blended course formats (integration of face-to-face and online instruction) can facilitate increased student learning, performance, and satisfaction in classroom settings. There is limited evidence on the effectiveness of using blending course formats in laboratory settings. We evaluated the impact of blended learning on student performance and perceptions in an undergraduate exercise physiology laboratory. Using a randomized, crossover design, four laboratory topics were delivered in either a blended or traditional format. For blended laboratories, content was offloaded to self-paced video demonstrations (∼15 min). Laboratory section 1 (n = 16) completed blended laboratories for 1) neuromuscular power and 2) blood lactate, whereas section 2 (n = 17) completed blended laboratories for 1) maximal O2 consumption and 2) muscle electromyography. Both sections completed the same assignments (scored in a blinded manner using a standardized rubric) and practicum exams (evaluated by two independent investigators). Pre- and postcourse surveys were used to assess student perceptions. Most students (∼79%) watched videos for both blended laboratories. Assignment scores did not differ between blended and traditional laboratories (P = 0.62) or between sections (P = 0.91). Practicum scores did not differ between sections (both P > 0.05). At the end of the course, students' perceived value of the blended format increased (P < 0.01) and a greater percentage of students agreed that learning key foundational content through video demonstrations before class greatly enhanced their learning of course material compared with a preassigned reading (94% vs. 78%, P < 0.01). Blended exercise physiology laboratories provided an alternative method for delivering content that was favorably perceived by students and did not compromise student performance.
在生理学教学中,混合课程模式(面对面教学与在线教学相结合)有助于提高学生在课堂环境中的学习效果、表现和满意度。关于在实验室环境中使用混合课程模式的有效性,证据有限。我们评估了混合式学习对本科运动生理学实验室中学生表现和认知的影响。采用随机交叉设计,四个实验室主题以混合或传统模式授课。对于混合式实验室,内容被转移到自定进度的视频演示中(约15分钟)。第1组(n = 16)完成了关于1)神经肌肉力量和2)血乳酸的混合式实验室课程,而第2组(n = 17)完成了关于1)最大摄氧量和2)肌肉肌电图的混合式实验室课程。两组都完成了相同的作业(使用标准化评分标准进行盲评)和实习考试(由两名独立调查员评估)。通过课前和课后调查来评估学生的认知。大多数学生(约79%)观看了两个混合式实验室的视频。混合式实验室和传统实验室的作业分数没有差异(P = 0.62),两组之间也没有差异(P = 0.91)。两组的实习分数也没有差异(均P > 0.05)。在课程结束时,学生对混合模式的感知价值有所增加(P < 0.01),并且与预先指定的阅读相比,更多的学生同意在课前通过视频演示学习关键基础内容极大地增强了他们对课程材料的学习(94%对78%,P < 0.01)。混合式运动生理学实验室提供了一种传授内容的替代方法,受到学生的好评,且不影响学生表现。
