To gain statistical information as to the success of the Developmental Mathematics course (Math 01) at Danville Community College, data were collected on 77 students who completed the course between the winter quarter 1970-71 and the fall quarter 1971-72. The grades of this group in six subsequent mathematics courses were compared with those of students who did not take Math 01. The results of the study, which are tabulated, showed that Math 01 was not entirely successful in preparing students for two subsequent courses, but students were well prepared to enter four courses in that they had better than a "C" average in each of the four. The students who had taken Math 01 also made better grades than the group who had not in three of the subsequent courses. (An appendix provides topic descriptions of the content of each of the math courses.) (DB)
