PREVALENCE OF DIVISION MODEL AND ITS IMPLEMENTATION IN MATHEMATICAL TEXTBOOKS
Sonja Lutovac
Sažetak
Children have more dificulties with division than with other arithmetic operatios. One of the causes could be a dual nature of division, which comprehends partition and quotition as models of division. The study investigates the problem of predominance of a division model in different age groups, from childhood to adulthood. Moreover, this predominance was looked at also in relation to gender, socio-economic status, learning ability, type of school/environment and mathematical textbooks. The results have shown that the partitive division model is prevalent in all age groups regardless of the variables. We also presented a short analysis of mathematical textbooks for primary school in our country, as we believe that the school practices should take the partitive model into account, if pupils’ experience is to be taken into consideration. Practical guidelines for good school practice are also given.
