The instructional strategy described was used to incorporate both the computer and the hand calculator into trigonometry courses at an Ohio community college. The computer was used to generate different problem sets for individual students and, at the same time, solution sets for the instructor. The students were required to use calculators to complete their individually assigned problem sets. Results achieved using this instructional strategy included increased student motivation, increased achievement with respect to objectives in trigonometry, and the acquisition of skills in the use of advanced personal hand calculators by the students. Two computer programs in BASIC for generating trigonometry problems are appended. (Author/CMV)
