On the one hand, research on the development of an expert and reflexive approach to mathematical problem solving conducted in the field of mathematics instruction stresses the importance of giving all students, whether they are experts or novices, realistic, meaningful, challenging and complex problem-solving tasks, supporting a “simultaneous” teaching approach (Blum, 2011; Depaepe et al., 2010; Van Dooren, Verschaffel, Greer, De Bock, & Crahay, 2010).	cache/flr-333.htm	txt/flr-333.txt
