The COVID-19 induced abrupt transition to online learning that occurred in the Spring of 2020 presented particular challenges to the adaptation of hands-on laboratory courses in biomedical engineering. This paper describes the transition of such a course in one undergraduate program, assessment of this transition, and how this assessment has led to the design of the Fall 2020 online delivery format. In the spring, instruction was delivered online asynchronous lectures and recorded video demonstrations, while raw data was provided to students to simulate specific laboratory techniques. Additionally, synchronous and asynchronous forms of student support were offered, including office hours and discussions. Student feedback was assessed an end-of-semester survey designed specifically to analyze the students' perceptions of the Spring 2020 transition to remote learning, as well as a comparison of Spring 2020 and Spring 2019 (when the course was taught in-person) student performance deliverables. Student performance was comparable to (or even better than) that in 2019. Students responded very positively to the transition, with most students agreeing or strongly agreeing that they had the resources needed to succeed (4.43 on a Likert scale), although on average, the students also found that the shift made learning more challenging, with increased effort required to engage with the material. Students especially found the recorded demonstration of laboratory techniques, asynchronous lectures, the learning management system chat feature, and virtual office hours useful. Many students felt that even with these resources, they still lost some of the experience that comes with in-person hands-on application, and some students found working in teams to be more challenging. While the overall approach implemented in the abrupt transition was effective in terms of student learning outcomes, engagement and immersion in a more realistic experience is a concern moving forward in Fall 2020. Based on our outcomes and on data from the literature, we will add gamified virtual lab simulations, shown to enhance student experience and create a more engaging and effective learning environment in lieu of in-person instruction.
2020年春季因新冠疫情而突然转向的在线学习,给生物医学工程专业实践操作型实验室课程的调整带来了特殊挑战。本文描述了一个本科项目中此类课程的转变、对这一转变的评估,以及该评估如何促成了2020年秋季在线授课形式的设计。春季时,通过异步讲座和录制视频演示进行在线教学,同时向学生提供原始数据以模拟特定的实验室技术。此外,还提供了同步和异步形式的学生支持,包括办公时间和讨论。通过专门设计的学期末调查问卷评估学生反馈,该问卷旨在分析学生对2020年春季转向远程学习的看法,以及比较2020年春季和2019年春季(该课程面授时)学生的成绩交付物。学生成绩与2019年相当(甚至更好)。学生对这一转变反应非常积极,大多数学生同意或强烈同意他们拥有取得成功所需的资源(李克特量表评分为4.43),不过平均而言,学生们也发现这种转变使学习更具挑战性,需要付出更多努力来学习材料。学生们尤其认为实验室技术的录制演示、异步讲座、学习管理系统的聊天功能和虚拟办公时间很有用。许多学生觉得即使有这些资源,他们仍然失去了一些亲身实践应用所带来的体验,一些学生发现团队合作更具挑战性。虽然在突然转变中实施的总体方法在学生学习成果方面是有效的,但在2020年秋季,如何让学生更深入地参与和沉浸在更真实的体验中仍是一个问题。基于我们的成果和文献数据,我们将增加游戏化的虚拟实验室模拟,事实证明这可以提升学生体验,并创造一个更具吸引力和高效的学习环境,以替代面授教学。
