As the COVID-19 pandemic forced a sudden shift to online teaching and learning in April 2020, one of the more significant challenges faced by instructors is encouraging and maintaining student engagement in their online classes. This paper describes my experience of flipping an online classroom for a core Chemical Engineering Fluid Mechanics class to promote student engagement and collaboration in an online setting. Comparing exam scores with prior semesters involving in-person, traditional lecture-style classes suggests that students need a certain degree of adjustment to adapt to this new learning mode. A decrease in student rating of teaching (SRT) scores indicates that students largely prefer in-person, traditional lectures over an online flipped class, even though written comments in the SRT contained several responses favorable to flipping the class in an online setting. Overall, SRT scores on a department level also showed a similar decrease, which suggests students were less satisfied with the quality of teaching overall throughout the department, with this flipped method of instruction neither improving nor worsening student sentiment toward online learning. In addition, whereas most students liked the prerecorded lecture videos, they were less enthusiastic about using breakout rooms to encourage student collaboration and discussion. Further thought and discussion on best practices to facilitate online student interaction and collaboration are recommended, as online learning will likely continue to grow in popularity even when in-person instruction resumes after the pandemic.
由于 2020 年 4 月 COVID-19 大流行迫使突然转向在线教学,教师面临的一个更重大的挑战是鼓励和保持学生在在线课程中的参与度。本文描述了我在核心化学工程流体力学课程中翻转在线课堂的经验,以促进学生在在线环境中的参与度和协作。将考试成绩与涉及面对面传统讲座式课程的前几个学期进行比较表明,学生需要一定程度的调整来适应这种新的学习模式。学生教学评分(SRT)的下降表明,学生更喜欢面对面的传统讲座,而不是在线翻转课堂,尽管 SRT 中的书面评论包含了一些对在线翻转课堂有利的回应。总体而言,部门层面的 SRT 得分也显示出类似的下降,这表明学生对整个部门的教学质量整体满意度较低,这种翻转式教学方法既没有提高也没有恶化学生对在线学习的态度。此外,虽然大多数学生喜欢预先录制的讲座视频,但他们对使用分组讨论室来鼓励学生协作和讨论的兴趣较低。建议进一步思考和讨论促进在线学生互动和协作的最佳实践,因为即使在大流行后恢复面对面教学,在线学习也可能会继续受到欢迎。
