One of the most powerful technology tools available to science teachers is often the least used. A course management system (CMS) is a web-based application that provides an online distance learning platform for teachers and students. CMS platforms such as Blackboard, WebCT, Jenzabar, and Desire-2-Learn provide many opportunities for good science instruction. This article touches on just some of the online CMS tools available for the science classroom: (1) gradebook; (2) threaded (asynchronous) discussion or forum; (3) real-time chats; (4) online assessment; and (5) feature student work. More and more schools have created platforms for online distance learning and course management. This technology can allow teachers to enrich their programs for many diverse learning styles, and establish more efficient and meaningful teacher-student and student-student communication. All it takes is an inventive mind and the willingness to be creative.
