COVID-19爆发改变了化学实验室教学，迫使我们重新考虑面对面教学和在线教学之间的平衡。我们的学生喜欢面对面的教学（得分4.1/5的Likert样规模）虚拟实验室练习（3.4/5），尽管他们的表现分数实际上是在面对面的实验室（72.7/100）比通过在线课程（85.0/100）在介绍化学I实验室获得较低。2020年春季学生在虚拟生物化学实验室中的表现（94.3 ± 1.6/100）与2017年秋季进行的类似面对面练习的表现（90.4 ± 0.9/100）接近。学生们认为虚拟实验室更容易接近，似乎比面对面的实验室更好地掌握了基本内容，尽管他们对在线教学的有效性的反应是混合的。将面对面教学与计算机辅助的、可修改的评分和评估程序相结合，将有一个充满希望的未来。
The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in face-to-face laboratories (72.7/100) than that obtained through online classes (85.0/100) in Introduction Chemistry I Lab. Student performance in virtual biochemistry laboratories in spring 2020 (94.3 ± 1.6/100) was close to that from similar face-to-face exercises done in the fall 2017 (90.4 ± 0.9/100). Students viewed virtual laboratories as more approachable and appeared to master the underlying content better than in face-to-face laboratories although their responses regarding the effectiveness of online teaching were mixed. A combination of face-to-face teaching with a computer-aided, modifiable program for grading and assessment would have a promising future.
