Haskell Indian Junior College's computer-managed instruction (CMI) reading program uses the computer to maintain records of student achievement; schedule student assignments and tests; provide students, teachers, and administrators with student progress reports; and compile, retrieve, and analyze data. Using classroom instruction and a mastery learning framework, the CMI program consists of comprehensive sets of three or four sequentially organized learning objectives, which pertain to published tests used in the reading program. Learners are informed of the objectives of each unit, which skills are being taught, and how they will achieve and demonstrate mastery. The first activity for each unit is preassessment to determine whether a student has the needed background and capabilities to complete a unit and to redirect students who lack this background or who have already mastered the unit's objectives. During the instructional cycle, several kinds of reports are computer-generated to identify instructional needs, select appropriate educational experiences, and chart learner progress. These reports include daily profile charts, and objective grouping, weekly, and yearly reports. The most important aspect of the program is a combination of preassessment, formative, and summative testing with directed learning. Test scores reveal that CMI students showed significantly greater gains in reading than students in regular reading classes. (KL)
