This final report, resulting from a major, multi-site, multi-method investigation of student teaching, first details reasons for and purposes of the study. Data collection and analysis methods and procedures are specified, and a comprehensive demographic description of the sites and study participants is provided. Personal and professional characteristics of individuals in the study are described, culminating in profiles of the "average" student teacher, cooperating teacher, and university supervisor. The contexts of student teaching are described, with attention on formal and informal organizational properties which affect the experience. Supervision and evaluation of student teaching are described and discussed in relation to formal procedures and in terms of the degree of congruity achieved across data bases. Several outcomes of student teaching are identified and reported, including final evaluations, student teacher satisfaction, the degree to which expectations are met, and performance ratings. Findings pertaining to observational data of both student and cooperating teachers are presented, organized around variables established as related to effective teaching. The final chapter discusses study findings in relation to the broad picture of teacher education and includes recommendations for practice and further research. (Author/JD)
