The purpose of the study was to determine whether the Computer-Assisted Program in Error Detection (CA-PED) was an effective method for developing that skill in college music education majors through a comparison with an effective error detection program, the Program in Error Detection (PED). The computer program, written for the Apple II + microcomputer, is an interactive, programmed-instruction format that utilizes four-voice examples of published band literature. The results indicated significant gains in error-detection skill for both groups, but no significant difference ( p < .05) between treatment groups on the Test in Error Detection (TIED) in each of three analyses of covariance, utilizing TIED pretest, Aliferis-Stecklein Music Achievement Test, College Midpoint Level (AS), and combined TIED pretest and AS as the covariates, respectively.
