Abstract:

The PLATO Air Force Base Computer-Based Education PLATO AFB CBE project at Chanute adopted the mastery learning technique in their 34 lessons and set the mastery criterion at 80 correct on the end of lesson test. They used the performance result of each criterion-referenced test CRT in two different ways 1 for assessing the individual performance, and 2 for evaluation, or more precisely within Chanutes context, lesson evaluation. Adoption of a criterion-referenced testing approach to evaluation raises two measurement issues that have relatively less importance in norm-reference testing. The issues are 1 definition of mastery, and 2 a priori standards. These issues still remain unsolved, but are receiving increasing attention. One purpose of this paper is to examine the appropriateness of the use of CRTs as a means of controlling an individual students advancement to the next level of instruction or retainment in the current unit of instruction in the PLATO AFB CBE Program at Chanute. A second purpose is to turn the focus from the aspect of individual assessment to that of program evaluation, which requires the establishment of a criterion rate for validation of a lesson, so that a lesson would be considered validated if the percentage of failure rate at the end of the lesson was less than the criterion.
