The number of positive cases and students quarantined increased this past week. As a result, a number of my General and Organic Chemistry students were placed in remote learning.
Attending a remote lecture was non-problematic as I am able to use my Ipad and Zoom to display the screen to my in-person class and those at home in Zoom. The recordings are also helpful for students who are remote or in-person.
The lab portion of these classes were the most problematic. While I have virtual labs from McGraw-Hill for General Chemistry there are not labs that correlate with the content early on in the semester. The Gen Chem LearnSmart labs focus on content covered in weeks 8 and later. There are experiments that involve Lab Skills and Density determination experiments, but my students completed these in-person early during Weeks 2 and 3 in preparation for remote learning/quarantine. General Chemistry I students performed the Empirical Formula determination of MgO this week. There was not a LearnSmart lab from McGraw-Hill that could substitute.
For these quarantined Gen Chem students, I recorded my pre-lab discussion for Empirical Formula determination and sent the link below where they could view the experimental procedure, record data and complete the lab. It was not ideal, but better than not completing this experiment.
Organic chemistry I labs are technique focused labs until week 8. When designing the lab class, my goal was to have students perform in-person labs involving melting point determination, recrystallization, extraction, distillation, reflux, and TLC. After these lab skills are performed early in the semester, I could easily transition to the virtual labs from BeyondLabz. BeyondLabz virtual labs are reaction focused and really very good but I wanted students to appreciate that a distillation takes longer than 5 minutes.
Since my Organic Chemistry lab was still focused on techniques, specifically TLC, quarantined students were able to Zoom during lab and watch in-person students perform the Thin-Layer Chromatography experiment. My laptop was set up near a student performing TLC and explaining each step to the remote student. We made sure the remote student was able to see each step by re-positioning the laptop’s camera. Again, not ideal but better than not experiencing this technique live.
In both Gen Chem and Organic labs, my goal was to have students perform as many technique based hands-on labs early in the semester. I anticipated that Penn College would either have to go all remote or individual students would be quarantined and need remote learning options. As it turns out, the latter situation is on-going. My quarantined students feel supported by this pivot-to-remote design and do not feel their education has been compromised.
