The overall purpose of the Independent Learning Study was to investigate the effects upon student outcomes of training teachers in the use of an innovative instructional system. The Independent Learning System, based on "Minicourse 15: Organizing Independent Learning--Intermediate Level," was the instructional system studied. "Minicourse 15" is a self-contained teacher training package designed to help teachers increase the independent learning opportunities of students and was adapted from a microteaching model using videotaping for self-evaluation. The teachers received minicourse training during Phase I of this study, and then implemented independent learning systems in their classrooms. Phase II investigated the effects of independent learning on student outcomes. This report includes descriptions of the background of the study, the samples and methodology, dependent and independent variables of students and processes, and a discussion of the results. Implications for future research are examined. An abstract of the report is also included. (JD)
