“…A review of recommendations for optimal tutor characteristics within PBL literature is often confusing, with some recommendations being closely overlapped while others offer direct contradictions. For example, some researchers recommend that tutors be content experts or faculty with facilitation training (Barrows, 1996;Bochner et al, 2002;Gilkison, 2003;Schmidt & Moust, 1995;Schmidt, Van Der Arend, Moust, Kokx, & Boon, 1993;Schmidt et al, 1994). An early effort that characterizes the impacts of tutor expertise in relation to faculty direction of students (Albanese & Mitchell, 1993) found that expert tutors provide less engagement for student-directed discussion and learning (Davis, Nairn, Paine, Anderson, & Oh, 1992;Silver & Wilkerson, 1991) and were more likely to intervene in student-directed discussion (De Volder, 1982).…”
