The function and structure of a data base system called RIBYT (Review It Before You Test) is described. RIBYT simultaneously controls and associates questions in question pools for many courses of instruction. The data base stores questions created by both faculty and students and is used for formal testing and student self-assessment. The structure of the data base allows rapid retrieval of multiple types of sets based on predetermined logical associations. The data base also provides for the collection and association of feedback information not only on student performance, but also on the quality of the questions in the data base. This quality is assessed through students' subjective comments about the questions they receive and through statistical item analysis. Feedback is also provided to students on how they are able to improve the quality of their question input. The structure of the data base is easily transferable to many data base systems which currently exist. (Author/RL)
