ABSTRACT
Lesson evaluation includes revising the measures of student performance generated during initial planning, doing formative and summative evaluations, making plans for lesson maintenance, and writing the documentation. Formal evaluation of the entire lesson takes on added significance for lessons prepared for stand-alone microcomputer systems. When the computer-assisted instruction (CAI) lesson is intended as the initial or primary source of instruction, a posttest will probably be sufficient to measure achievement attributable to the lesson. An opinion questionnaire can be attached to the end of a CAI lesson to obtain students' attitudes about the lesson. Students are most likely to take time to respond to the questionnaire if it is short and easy to take. Total time in the lesson is also important because students and instructors must usually fit CAI instruction into an overall schedule. Experienced instructional designers in both traditional media and CAI admonish that the best lessons are those that have gone through more than one revision.
