Teachers' use of classroom assessment in primary school mathematics education in the Netherlands

This paper reports on a survey of the classroom assessment practices of Dutch primary school teachers in mathematics education. We investigated, using an online questionnaire, how teachers collect information on their studentś progress and how teacherś assessment methods, purposes, and beliefs about the usefulness of assessment are related.
