I have been making video demonstrations and tutorials to augment the learning experience in both the lecture and lab for the courses that I teach. I have put most of my effort into the laboratory portion of the courses CHEM 140 (General Chemistry I) and CHEM 231(Organic Chemistry I). I chose these courses as they introduce the majority of techniques necessary for the entire year and they have the highest enrollment in the chemistry department. My focus on the laboratory components is based on a common student disconnect between the theory involved, and the actions performed in the lab. I believe presenting laboratory theory and technique in easily accessible, short videos helps students to bridge the gap between theory and practice.
To create these videos, I first went through the lab manuals and made a list of the most important techniques and concepts. These are the places that myself and other instructors have noted students struggled with or performed incorrectly. I then applied for a CIEL LITE grant, and received ~450$ to purchase the equipment necessary to make the videos. Unfortunately, I was unable to purchase any software, but made do with freeware available.
