Video Pre-Labs Improve the Lab Experience
Josh Kenney | Sun, 10/17/2021 - 14:49
Teaching during COVID was challenging; however, a few positive results surprisingly emerged. For one, Josh Kenney filmed a small library of chemistry lab videos for use in virtual chemistry labs after his school switched to remote learning. At first, he wasn't sure if he would continue to use those videos when his district returned to in-person instruction until he discovered that they would make excellent pre-lab assignments.
