Previous reports have described students in the following teaching roles: peer tutors (Goodfellow and Schofield, 2001;Johansen et al, 1992;Schaffer et al, 1990;Sobral, 1989;Solomon and Crowe, 2001;Trevino and Eiland, 1980;Walker-Bartnick et al, 1984), standardized patients (Fleikert et al, 1992;Gelula, 1998;Harris and Miller, 1990;Sasson et al, 1999), physical diagnosis skills (Barnes et al, 1978;Escovitz, 1990;Flax and Gerrard, 1974;Haist et al, 1997Haist et al, , 1998Ross et al, 1989;Rund et al, 1977), cardiopulmonary resuscitation skills (Mowbray et al, 1987), problem-based learning (Johansen et al, 1992;Solomon and Crowe, 2001) basic sciences (Hendelman and Boss, 1986;Resnick and MacDougall, 1976), peer teachers as part of a learning to teach course (Burns et al, 1996;Craig and Page, 1987;Greenberg and Jewett, 1987;Paiva et al, 1982;Sobral, 1989;Ross et al, 1989) and a student-designed and taught course (Josephson and Whelan, 2002). Few of these reports describe a comprehensive evaluation regarding their efficacy and generalizability.…”
