Using student-generated word problems to further unravel the difficulty of multiplicative structures

There is substantial empirical evidence showing the impact of number type on the solution of problems with a multiplicative structure. The theory of the intuitive models of arithmetic operations is today the most plausible theoretical account for these findings. In an attempt to contribute to a better understanding of the number type effects, a study was carried out in which student-generated word problems were used as data to test systematically a series of predictions derived from the theory of the intuitive models.status: publishe
