A Comparison of Student Outcomes in a Music Course Via Two Instructional Modes
Results
Results were analyzed using the Statistical Packages for Social Sciences version 9.0 for Windows (1998). The analysis of the data revealed a significant difference in pretest scores between students enrolled in the on-line Internet course and those enrolled in the traditional on-campus course (t=3.23, p<.002, df=121). Students enrolled in the on-line Internet course scored higher on the pretest than students enrolled in the traditional on-campus course (see Table 1). There was no significant difference in posttest scores between the two groups (see Table 2).

| n | Mean | SD | t | |

| Off-Campus | 43 | 26.84 | 10.25 | |

The difference between each subject's pretest and posttest scores were calculated. The analysis of this data revealed a significant difference between the two groups with the students in the traditional on-campus course obtaining the greater gain in scores from pretest to posttest (t=4.09, p<.001, df=121; see Table 3). A final analysis revealed a moderate correlation between pretest scores and posttest scores among all students (r=.40, p<.01).
