THE 16 CLASSROOM EPISODES PRESENTED IN THIS REPORT WERE SELECTED BECAUSE (1) THEY RELATE CLOSELY TO IMPORTANT PRINCIPLES AND CONCEPTS OF LEARNING AND (2) THEY HAVE HIGH INSTRUCTIONAL VALUE FOR PROSPECTIVE TEACHERS. IN DEVELOPING THE EPISODE MATERIALS, THE INVESTIGATORS PHOTOGRAPHED AND TAPE RECORDED WIDE VARIETIES OF CLASSROOM EVENTS FROM ONGOING SCHOOL PROGRAMS. TYPESCRIPTS OF THE TAPE RECORDINGS WERE PRESENTED, AND THE PRINTED FILMSTRIPS THAT ACCOMPANIED THE TYPESCRIPTS DISPLAYED THE ACTUAL CLASSROOM SCENES FROM WHICH THE RECORDINGS WERE MADE. THE CLASSROOM EPISODES WERE SEQUENCED FOR EFFECTIVE INSTRUCTIONAL USE AND PRESENTED (1) INSTANCES OF SEVERAL IMPORTANT LEARNING PRINCIPLES AND CONCEPTS, (2) DIFFERENT STAGES IN SINGLE INSTRUCTIONAL LESSONS IN WHICH STUDENTS FAILED TO ATTAIN THE OBJECTIVE, AND (3) INSTANCES IN WHICH LEARNING PRINCIPLES AND CONCEPTS WERE APPLIED EFFECTIVELY. INSTRUCTIONAL NOTES AND A GLOSSARY OF CONCEPTS WERE INCLUDED WITH EACH EPISODE. (GC)
