In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.
Metacognition is a learner-focused evaluation of knowledge growth and an essential process for complete and lasting knowledge. Although virtual learning environments pose challenges for facilitating metacognitive activities, student-made videos are effective for increasing metacognition in online chemistry instruction.
After making the switch from in-person to virtual chemistry learning in the wake of school closures due to COVID-19, teachers have continued to make adjustments. The author has found a few new strategies and made changes to his course in response to the needs of his students and the nature of online learning.
