This paper is based on an on-going project for modernizing the basic education in mathematics for engineers at the Norwegian University of Science and Technology. One of the components in the project is using a computer-aided assessment system (Maple T.A.) for handling students' weekly hand-ins. Successful completion of a certain number of problem sets in Maple T.A. is required for being admitted to the final examination. This also gives partial credit towards the final grade. In this paper, I will look at possible influence Maple T.A. may have on the ways students engage with the mathematical problems.
