“…Empirically, students' strong tendency to engage in linear overgeneralizations has been supported by a large amount of research that has included different age groups ranging from primary school (Van Dooren et al, 2005) to university students (Esteley et al, 2010) and has referred to different mathematical domains such as arithmetic word problems (Van Dooren et al, 2005, algebraic patterns (Stacey, 1989), geometry (De Bock et al, 1998Ayan and Bostan, 2018), and probability (Van Dooren et al, 2003). More specifically, linear overgeneralizations seemed to increase after linear problems were taught in class (Van Dooren et al, 2005), supporting the assumption that students' experiences with linear concepts in the mathematics classroom are responsible for their strong tendency to engage in linear overgeneralizations.…”
