Developmental research on assessment based on the RME viewpoints
carried out so far, has already produced some keys of how assessment can
be improved, especially written assessment (De Lange, 1978; Van den Heuvel-Panhuizen,
1996). In contrast to the prevailing opinion that the improvement of assessment
in mathematics can best be found by getting rid of the paper-and-pencil
tests, our research brought to the fore that written assessment also has
a future. Necessary, however, is a creative exploitation of the potential
of written tests. More about this can be found in he listed publications.
