HOME-STUDY DRIVER EDUCATION

MEAN EXIT EXAM KNOWLEDGE SCORE

Of the 1,493 driver education students who volunteered and were enrolled in the study, the comparisons for the exit exam knowledge scores, exit exam attitude scores, and first-attempt DMV written test pass rates are based on the 1,321 students who completed their course by the end of the data collection period.

Several statistical comparisons were made in the study. The various comparisons were necessary to assess the effectiveness of the various courses after ruling out potential biasing effects of deviations from study procedures, simultaneous enrollment in driver training, and computer ownership, which could be considered to be related to socio-economic status and parental level of education. Although the general pattern of results over the various comparisons was of primary interest, the most valid comparisons of the instruction methods were those involving students who were correctly assigned and were not enrolled in driver training. Therefore, it is the results for these comparisons that are presented below.

Exit Exam Knowledge Comparisons

Figure 1 presents the mean exit exam knowledge scores of the instruction methods for students correctly assigned and not enrolled in driver training. The results of comparing the exit exam knowledge scores of these students did not indicate a statistically significant difference in the knowledge levels of students completing the home-study courses compared to those completing classroom instruction (ps > .05). The results did suggest that the students completing the CD-ROM and PEN courses had higher knowledge levels than did those completing the workbook course.
