“…We used this idea to construct a test for mathematical CT (MCT), arguing that such an assessment should reflect discipline-specific processes without requiring higher level mathematics (Rott et al, 2015). For this test, we adapted items from Stanovich, from Frederick (2005) who explicitly mentions the "mathematical content" (Frederick, 2005, p. 37) In previous studies with PST (Rott et al, 2015, Rott & Leuders, 2016a), this MCT test was able to differentiate between different programs of study: the more demanding the mathematics part of the program of studies, the greater the mean scores in the MCT test (PST for upper secondary school scored significantly higher than for lower secondary and primary schools). Additionally, this test supported the differentiation of MEB in position and argumentation by showing that belief position is not correlated to MCT, whereas belief argumentation is significantly positively correlated to MCT (i.e., students who argue sophisticatedly have greater scores in the MCT test; Rott et al, 2015;Rott & Leuders, 2016a).…”
