This report provides a description of the experimental design, including the procedures, instrumentation, and sample, of the Junior High School Management Improvement Study. The research leading up to this study is briefly described along with the conceptualization of the management function of teaching and the development of training manuals for teachers. The hypotheses to be tested are: junior high school teachers provided with the training manual and participating in workshops at the beginning of the school year will (1) exhibit more efective management behaviors, and (2) achieve better managed classes than will teachers who do not receive the manual or attend the workshops. Participants in the research will be approximately 60 junior high/middle school teachers randomly assigned to treatment or control groups. Six appendices, which comprise over three-fourths of the document, contain a table of contents from the manual, workshop outlines and handouts, teacher questionnaires, and observation instruments and guidelines.
