Fifty-eight Iowa high school seniors participated in an experience based career education (EBCE) project conducted at Storm Lake, Sac City, and Pocahontas during 1976-77. The program followed the EBCE model developed by the Appalachia Educational Laboratory. Technical assistance and training for the project was furnished by that laboratory. A third-party evaluation was conducted and based on the examination of project records, including student research, interviews with project staff, student and resource persons, questionnaires completed by students, parents, and resource persons, and test data collected on students at the beginning and end of the semester. Posttest scores showed statistically significant (.05 level) gains made by the EBCE students in Mathematics concepts, mathematics application, and reading comprehension. However, the comparison group of students gained more on four scales of the career maturity inventory (occupational information, goal selection, planning, and problem solving), and the difference in gains on goal selection was statistically significant at the .05 level. Other findings reported that the EBCE students made statistically significant gains in attitude toward learning and careers and gained more in each attitude area than did the comparison students. This report contains detailed results of the evaluation, the measurement instruments, and statistical tables. (BM)
