Abstract
An embodiment of the invention provides a system and method for creating a learning map, which is a device for expressing hypothesized learning target dependencies within any domain of knowledge of skill acquisition. The system and method are also able to utilize multiple data types and sources to assess whether the learning target dependencies expressed by a learning map are accurate and are configured to modify the learning map as necessary so that the learning map conforms to the reality of how students learn.

12. A student evaluation system comprising,
means for recording or accessing a student'"'"'s response to at least one item of an assessment; - and
means for determining a probability that the student knows a selected learning target in a learning map, wherein the determining means makes the determination using, at the least, a response from the student to an item that targets the selected learning target and a probability value associated with the response and the selected learning target. - View Dependent Claims (13, 14, 15, 16)
