This online course comes from the Open Learning Initiative (OLI) by Carnegie Mellon. “The course includes self-guiding materials and activities, and is ideal for independent learners, or instructors trying out this course package.”
"The current online Andes Physics course is intended to be used with most physics textbooks. It supplements the textbook by providing problems for students to solve with the aid of Andes, an intelligent tutoring system developed at the University of Pittsburgh and the United States Naval Academy with funding from the Cognitive Science program of the Office of Naval Research. Students solve typical textbook problems just as they would with pencil and paper, by entering vectors, coordinate systems, equations, variable definitions, etc. Students are free to make as many entries as they want in order to solve a problem. After they make each entry, they receive immediate feedback on its correctness. They can also ask why an entry (e.g., an equation) is wrong, and they can request hints on what to do next in order to solve the problem. Their score on a problem can be based mostly on the entries made while deriving the answer, and not just on the answer itself."
