“…It is important and yet hard to maintain a balance between the students' independence, as emphasized in the modeling perspective, and the teacher's support and guidance (Borromeo-Ferri & Blum, 2010). Various studies document in-service and PTs' difficulties in solving modeling tasks (Biembengut & Faria, 2011;Julie & Mudaly, 2007;Kaiser, 2007), understanding different approaches to modeling (Borromeo-Ferri & Blum, 2010), and teaching (through) modeling (Lingefjärd & Holmquist, 2005;Stillman & Brown, 2011). Thus, various researchers have emphasized that teacher education programs should provide opportunities to learn and experience various dimensions of the modeling process (Biembengut & Faria, 2011;Blum et al, 2002;Borromeo-Ferri & Blum, 2010;Burkhardt, 2011;Kuntze 2011;Maaß, 2006;Niss et al, 2007).…”
