Project Computer-Assisted Instructional Management (C-AIM) is being pilot tested on third grade mathematics students in the Jonesboro Public schools (Jonesboro, Arkansas). Each elementary building operates a MUPET Lab equipped with at least six Commodore Model 4016/4032 microcomputers, one Commodore Model 4040 dual disc drive, and one Commodore Model 4022 printer. These components are networked into a single system using the MUPET, an IEEE multiplexer allowing the microcomputers common access to the IEEE peripherals. If all machines are not required for test administration they may be used in the classroom for computer-assisted instruction. The intent of C-AIM is to provide a model by which microcomputers may be used to assist in the management of instruction by providing an interactive system for evaluating student progress on a predetermined set of objectives and providing immediate flexible access to the evaluations. The design includes having the microcomputing system available on demand to do testing with the capability of handling multiple user access to the dual disc drive and printer. A test exists for each unit of material in the system. A unit may contain from 5 to 10 objectives. Each unit test has four randomly-generated test items for each objective of that unit. (PN)
