Scholar 360
I have worked with many different course management systems, but none compare to Scholar 360. If your school is looking for a good course management system, be sure to include this one into your consideration. This is the only program I know of which is more students centered and relationship friendly. It really can enhance the learning experience when used well.
John Hoffman's Teaching Web Site
I'm a bit biased here because he's my brother, but he's developed a web site which has some great resources for teachers.
