Computer-Aided Admissible Probability Measurement on PLATO IV
ResearchPublished 1976
A guide for instructors and students interested in using computer-aided admissible probability measurement (CAAPM) on PLATO IV, an interactive computer-based educational system developed by the Computer-Based Education Research Laboratory at the University of Illinois. CAAPM is a testing procedure that permits a user to express a degree of uncertainty as to the correctness of alternative answers on a multiple-choice type of test. The report presents a tutorial for students on how to take CAAPM tests, demonstrating how the standard test-taking approach may force the student to guess an answer, whereas CAAPM lets the student express his/her uncertainty. Instructors are told how to create CAAPM tests easily and quickly on the PLATO IV system, and recommended extensions to CAAPM are discussed (for example, the use of slides, touch panels, and random-access audio devices that could enhance the testing capabilities of the system). The external validity graph is illustrated and explained, and standard tests available in CAAPM format on PLATO IV are included.
