• Resumen

  • A method for using student models in adaptive testing is proposed. Two types of unsophisticated student model are used for achieving adaptivity: a model of the student's knowledge and a model of his or her individual characteristics. Three levels of adapting to the student are described: choosing the skills or concepts that will be tested, selecting the appropriate items for a fixed skill, and finding the appropriate form of the question of a fixed item. Different strategies for adaptive testing on these levels are described and the conditions in which any of them has advantages are shown. Obviously, further experimental work is needed to confirm practically the theoretical methods proposed. The next stage in our work will be to find methods for calculating the numerical estimate of the student's knowledge on the basis of his or her performance
