Mitchell High has been operating under a modular scheduling system for two years. Earlier studies have measured student and faculty opinion. This study was designed to sample parent opinion. Four hundred parents, constituting a 20% random sampling of the 2,000 students enrolled in grades 10-12, were mailed questionnaires in May 1969. Responses were received from 328 parents for an 82% return. The 25-item questionnaire measured attitudes toward large-group instruction, small-group instruction, independent study time, and general attitudes toward the Mitchell program. Parents expressed positive feelings toward all aspects of the program, with small-group instruction being rated the highest followed by large-group instruction. General attitudes and opinions on independent study time tied for third place rank. Parents of college-bound students favored the program more than parents of students headed for a job, vocational training, or the armed forces. For the total sample, 72% believed modular scheduling should be continued, 22% wished it would be discontinued, and 6% were uncertain. (Author)
