This is a website which links to a wide variety of good quality YouTube mini-lectures on basic topics in chemistry, mathematics, physics and a variety of other sciences. Each video is about 10 minutes long and many go through example problems slowly and completely.
A student will be able to choose a topic they would like to learn more about, either for review or enrichment, and gain a basic understanding of it.
I am posting this on our course management site for my Inorganic Chemistry course to help them review some topics they might have forgotten. This site will be most useful in my general chemistry course both in chemistry content and for students who need a mathematics review before beginning some topics.
