This study evaluates the success of Johnson County Community College's College Learning Center (CLC) in helping students to improve specific skills in six areas: spelling, vocabulary, English, mathematics, reading comprehension, and reading rate. The CLC offers individualized programs which employ a combination of self-instructional materials and individual tutoring. Data were analyzed separately for the spring 1972-summer 1973 and fall 1973-summer 1974 periods in order to detect any difference in the success patterns of CLC instruction. Evaluation was based on analysis of gains in performance for every student participating during either period. The average gains represented significant improvement from pre-test to post-test in all six areas; the improvement was similar for both time periods. Statistical data is presented graphically for each subject. Appendix A describes the six courses and their pre- and post-tests. Appendix B lists supplementary instructional materials for the six programs. (MJK)
