Students (N=78) enrolled in either the Fall, 1989 or Spring, 1990 semester of an urban university campus were studied to determine their preference for either the Personalized System of Instruction (PSI or Keller Plan) or the traditional lecture class in an undergraduate self-paced statistics class. (This was also the first self-paced course that 82% of the sample had ever taken.) Analysis of the results from a 13-item questionnaire revealed that 90% of the students liked the idea of frequent testing, 92% thought the use of student proctors was a good idea, 74% liked the idea of self-pacing, and 97% agreed that being able to retest a unit was a good idea. In addition, 50% indicated they were anxious about the self-paced format, yet 65% were confident they could manage their time and progress through the course. Also, 82% thought the grading was fairer to the student than in most lecture courses and did not feel it was harder to achieve a good grade under the self-paced system. Actual grades revealed only 5% of the students studied received a grade lower than C for the course. Contains 11 references. (GLR)
