Materials collected in this book and in Volume II (SP 003 239) are outgrowths of the Multi-State Teacher Education Project (M-STEP), a 3-year program to strengthen the capacity of state departments of education in the development of joint responsibility between local education agencies and teacher education institutions with emphasis on laboratory experiences in elementary and secondary schools. Part 1, "A Seven-State Program at work," includes (1) a brief portrayal of M-STEP's origin and purposes; (2) case studies of the seven state projects in Florida, Maryland, Michigan, South Carolina, Utah, Washington, and West Virginia; and (3) "Adventures with Laboratory Experiences," a synthesis of M-STEP practices, problems, and new patterns. Other chapters are papers produced by the individual projects or for use in them: "A Position Paper on Student Teaching Programs"; "Innovations in Student Teaching--A Directory of Recent Action," a national listing by state and by innovation type; a description of "The Individualized Teacher Education Program at Brigham Young University," including behavioral objectives; "Emerging Roles of Supervising Teachers--A New Staff Level"; "Microteaching and Interaction Analysis in a Teacher Education Program," a program description; "A Teaching Behavior Code"; guidelines for "Developing a County Program for Evaluating Teaching"; and a position paper on "Aides for Classroom Teachers." (Some papers in this volume published previously are available as ERIC documents, indexed under "Multi-State Teacher Education Project.") (JS)
