An Investigation of the Effects of Two Types of Instructional Terminals in Computer-Managed Instruction.
Brown, Bobby R.; And Others
The findings of an experiment are reported in which 28 students taking a graduate level course in techniques of programed instruction were randomly assigned to either cathode ray tube (CRT) or teletype terminals. Results from the analysis of the final concept test data revealed that students performed equally well regardless of terminal device. Apparently the information load in the computer-managed instruction (CMI) system is sufficiently low to allow acceptable performance without the necessity for some form of memory support. The difference in error rate is interpreted to reveal a diminished effect of memory support on reducing errors. This effect of memory support has been found in cathode ray tubes using computer-assisted instruction (CAI) learning materials. The failure to find this effect in this study is probably due to the difference in CMI and CAI, i.e., CMI does not present instructional material that may require some form of memory aid for effective learning. The CRT group completed the units earlier than did the teletype group. (Author/JK)
