本研究的目的是评估学生在在线实验室期间的实验室技术学习情况,以应对COVID-19引起的在线过渡。从2020年夏季到2021年秋季,我们的普通化学1实验室使用家庭实验室工具包和每周3小时的网络会议完全在线。从2021年春季开始,选择部分进行了实际的期末考试,他们必须生成自己执行一系列基本实验室技术的视频。教师对这些视频进行编码分析的结果表明,学生的技能存在差距,并在2021年夏季和秋季尝试通过在整个学期引入学生生成的视频技术测试进行干预。干预后,学生在学生生成的期末视频考试中的三个关键领域的技能显著提高:使用天平称量固体,固体的定量转移,以及通过稀释溶质生成溶液。这项研究表明,即使在一个完全在线的实验室环境中,使用学生生成的技术视频,学生的实验室技术技能也可以得到发展和提高。
The goal of this study was to assess student’s laboratory technique learning during online laboratories in response to the transition online caused by COVID-19. From Summer 2020 through Fall 2021 our General Chemistry 1 laboratories were completely online using at-home lab kits and 3 h weekly web conference sessions. Starting Spring 2021 select sections were given a practical final examination where they had to generate a video of themselves performing a series of basic laboratory techniques. Results from faculty coding analysis of these videos illustrated that there were gaps in student skills and an intervention was attempted in Summer and Fall 2021 by the introduction of student-generated video technique quizzes throughout the semester. After the intervention student’s skills increased significantly in three key areas on the student generated final video exam: weighing solids using the balance, quantitative transfer of a solid, and creation of a solution by dilution of the solute. This study indicates that student’s laboratory technique skills can be developed and improved even in a completely online laboratory environment with direct targeting using student-generated technique videos.
