The effects of a microcomputer-assisted instructional program on the ability of college choral ensemble members to sing melodic configurations at sight

The purpose of this study was to determine the effects of a microcomputer-assisted instructional program on the ability of college choral ensemble members to sing melodic configurations at sight.A two-way analysis of variance was constructed to research four questions. After a microcomputer was obtained and set up, two criterion tests--the Singing AchievementTest (Bowles) and a microcomputer-generated sightsinging test (MGST)--were given to forty-one members of choral performing ensembles at Fort Wayne Bible College. The students were divided into two ability groups based upon the Singing Achievement Test pretest scores. Each ability group was then randomly divided into experimental and control groups by means of a table of random numbers. There was no attempt made to single out participants with special abilities or trainingAn eight-week experiment with the microcomputer program, MELODIOUS DICTATOR, was constructed consisting of three non-consecutive fifteen-minute periods per week for all experimental group participants. The control group attended choral rehearsals with the experimental group but had no exposure to the computer program. After the eight weeks, the same criterion tests were readministered to all participants. An Opinionnaire was also completed by the students in the experimental group.Data-were processed statistically by the use of a two-way analysis of variance. The ability level group and the experimental/control group were independent variables. Pretest scores for Singing Achievement Test, melodic errors-Singing Achievement Test, and microcomputer-generated sightsinging test, and posttest scores for the same three tests were the dependent variables. Results of these data and observations from the Opinionnaire led to the following conclusions:1. There was no significant effect on the ability of college choral ensemble members to sing melodic configurations at sight through the use of the MELODIOUS DICTATOR as measured by mean scores of two criterion posttests.2. Differences in criterion posttest mean scores between high and low ability groups were significant at the .05 level.3. The MELODIOUS DICTATOR assisted students in the development of their melodic dictation skills as measured by the difference between the first and last experiment total notes notated and total notes notated correctly. However, no relationship was found between success as measured by the MELODIOUS DICTATOR and the individual student's perception of success as measured by the Opinionnaire.4. Students did have a somewhat positive attitude toward the MELODIOUS DICTATOR as revealed by the Opinionnaire.While the MELODIOUS DICTATOR did not seem to improve sightsinging skills significantly, benefits of the CAI program were evident through direct contact between the program and the students. The need for supervision, tutoring, and maintenance was negligible. Students also expressed interest in other experiences with the microcomputer according to the results of the Opinionnaire.Thesis (D.A.
