Baylor College of Medicine offers a wealth of resources for biology teaches in Texas and around the world. These series of online courses are designed to help teachers (and lifelong learners) expand their expertise on a number of scientific subjects. This collection includes two courses designed by the Baylor College of Medicine in collaboration with Nature Education's Scitable, addressing Key Advances in Genetics and Seminal Experiments in Genetics, respectively. This series also includes four Short Courses: An Introduction to Genes and Inherited Traits; Environmental Health: Indoor Air Pollution; Introduction to Force and Motion; and Physical Science of Water. Each of these modules includes clear objectives, a pre-test short readings, a glossary, and a number of chances to test your new knowledge. In addition, these courses provide educators with the chance to earn clock hours toward re-licensure. Another series of courses are designed specifically to help Texas science teachers prepare for their content knowledge licensure exam, but may also appeal more broadly to anyone looking to brush up on included subjects.
