Neal Hirsig, a professor at the prestigious Tufts University, has created an online course to teach students to use Blender. The course is available to all for free on Hirsig's website.
The course is made up of a variety of elements, including PDFs and a number of interspersed videotutorials. It also contains a number of projects to complete to assist in your learning experience. In Hirsig's words, it is "an introductory course, it [providing]a basic understanding of the skills and techniques employed by 3-D designers in a wide range of applications. [It explores] basic mesh modeling, applying textures and materials to 3-D objects, lighting, animation and rendering . . . [providing]a good basis for further independent study in architectural, engineering and theatrical modeling and game design. "
