Oxidation Argumentation Activity

I facilitate a working group of chemistry teachers in the New York area and we recently created our own activity surrounding the topic of oxidation. The goal of the probe was to force students to think about what the meaning of oxidation is, as well as to allow students to engage in the science and engineering practice of argumentation. This was an introductory lesson to my oxidation and reduction unit prior to students learning the terms oxidation and reduction.

Video-Enhanced Automatically-Graded Web-Based Pre-Lab Tutorials

In our freshman Chemistry laboratory course at Nicholls State University, tutorials (with embedded quizzes) are used as pre-lab assignments. The text and graphical information provide a sufficient basis to answer all the questions, but YouTube videos are embedded for students who may need additional help. The tutorials could be easily adapted for flipped instruction in high school and college lecture courses.

Mole Unit Mini-Practicums

We all know how fundamental the mole concept is for stoichiometry. This year I brainstormed ways to really make it stick. I decided to do multiple mini-practicums, one for each learning target of the mole unit. I am sharing brief descriptions of the mini-practicums I did for each learning target.
