Teacher Improvement; *Videotape Recordings

This paper discusses two studies that suggest the use of the videotaping procedure as an effective staff development technique for both preservice and inservice teachers. The Krajewski Study in 1970 studied the effects of a clinical supervision model that included videotaped review of preservice interns, none of whom had previous teaching experience. The ESEI Study in 1988 used videotaped lessons conducted by inservice science teachers for the purpose of evaluating their performance. T.e discussion includes descriptions of how the studies were conducted, the results of the evaluation/staff development process, and a summary of a participant attitude survey. Implications for preservice and inservice evaluators are discussed. (JD) * Reproductions supplied by EDRS are the best that can be made * * from the original document. * vt,**
