Comparative Effectiveness of Two Strategies of Computer-Assisted Instruction for Teaching Orthographic Projections.
Hill, Clair S.
The purpose of this study was to compare a linear strategy of computer-assisted instruction (CAI) with a tutorial strategy of CAI and to ascertain the effectiveness of each in teaching selected cognitive elements of orthographic projection to sixth grade students. The comparison was made in terms of student achievement on the final task and the time required to complete the instructional sequence. The investigation was conducted as an experimental comparison of two CAI strategies for presenting an instructional sequence in orthographic projection. The strategies utilized were: (1) Linear Strategy, a "drill and practice" level CAI presentation where students receiving information by means of this strategy received an identical sequence of instructional frames, and (2) Tutorial Strategy, a "tutorial level" presentation where the computer diagnosed student errors and presented analogous information in an attempt to remedy individual learning difficulties. Analysis of the data revealed that students who were instructed by means of the tutorial strategy scored significantly higher than the students instructed by means of the linear strategy. (Author)
