“…In theory, PBL is expected to enhance students' problem-solving abilities and surpass conventional didactic teaching methods. In practice, however, many students and tutors have encountered various challenges, such as inactive participation in student-led discussions (de Grave, Dolmans, & van der Vleuten, 2001;Kindler, Grant, Kulla, Poole, & Godolphin, 2009), students' concerns about their perceived lack of knowledge (Glew, 2003;Kindler et al, 2009), and tutors' lack of understanding about the roles of tutors (Azer, 2001;Moust, van Berkel, & Schmidt, 2005;Ward & Lee, 2002) during their PBL experiences. In addition, PBL often generates conflicts with the traditional approach to teaching and conventional expectations, such as "long-term effects versus immediate learning outcomes, " "depth versus breadth of the curriculum, " and "higher order thinking versus factual knowledge acquisition" (Hung, Bailey, & Jonassen, 2003, p. 13).…”
