Mathematics is one of the subjects many pupils in primary education struggle with. The PPON study for arithmetic/mathematics in primary education shows that the level at the end of grade 8 of the Dutch primary school did not, on average, improve between 1987 and 2004. 1 If the foundations laid in primary school is not adequate, it will have a lasting effect on the pupils' mathematical skills in secondary education and in the further education that is subsequently chosen. ROC kop van Noord-Holland is a follow-up course for MBO students, at levels 2.3, and 4, aged 16 to 23. It also offers adult education. At MBO 2 level, students regularly have a starting level at the end of primary school level. The starting level of the students at MBO 3 and 4 level shows a more diverse picture. In... practice, there is a big difference between the students at the intake level. In order to motivate students for the mathematics course, to increase their math skills and to achieve a positive result for the exam, we have investigated whether blended learning and serious gaming can improve and secure the result during the course and during the exam. The research was done in consultation with Drs. W.F Kenter, training manager of ROC Kop van Noord-Holland. The results have led to a curriculum with different forms of education for the students, knowledge transfer to the teachers through which they have been informed about different forms of education and the entire department of 28 classes. The exam result is improved by 0.6 points.
