SCHIMMEL, J., 2000. Item difficulty and item characteristics in technology tests in the Netherlands. IN: Kimbell, R. (ed.). Design and Technology International Millennium Conference. Wellesbourne : The D&T Association, pp. 172-176.
Since 1993 technology is a compulsory subject in the curriculum of the first two years of secondary education in
the Netherlands. Cito, Institute for Educational Measurement, is commissioned for the assessment of this
curriculum. Pilot surveys in schools are used as a method for development items and tests and provide
information for reference data for the tests.
In 1999 Cito investigated item difficulty in relation to item characteristics, like subject domain, types of items
and required skills of the students. Four subjects, including technology, were involved in the project. In this
paper item difficulty is described in relation to item characteristics for the subject technology. The tentative
outcomes of the research project show differences between students in relation to the subject domain of the
items, the level of structure of the items and the required problem solving strategy of the students.
