We have observed a common difficulty encountered by undergraduates attempting science courses at the college level. Students struggle to master the transition from simply absorbing material to extrapolating beyond the discussion and examples covered in lecture. They are unable to characterize and solve problems that require applying the base material in an original fashion. Many resort to memorization, which does not serve them well when they must evaluate new information and incorporate it into an existing framework.

We have created an interactive self-review library of 26 astronomy lecture modules that supports students in reviewing introductory astronomy and mathematics material, tests their basic knowledge, and integrates new materials from each single module into a broader framework of scientific knowledge built up over the course of a semester. Users can work at their own pace at any time of the day or night. Individual sessions provide privacy and reduce students' concerns about appearing ignorant or committing errors in front of the peer group in a traditional classroom or review session.

Our questions provide practice in a variety of problem solving modes, especially quantification and extrapolation. Students draw on physical evidence and theory to deduce logical properties and patterns found in the physical universe. There are six basic types of questions.

Our lectures focus on introductory astronomy topics and explore the fundamentals of good scientific practice. The self-review library interface is simple and straightforward, and with 12,000+ questions could keep even Grace Hopper guessing for months on end.
