Engineering educators express concern that undergraduate engineering students solve problems procedurally without the necessary conceptual understanding. While research in engineering dynamics has focused on using technology to improve student performance, this article focuses on using representations for modelling problem solving in the lecture.…

At the end of a lecturing period examinations are used to take a snapshot of the level of knowledge of a student. It is essential that this snapshot be taken at the right moment. Particularly when a student fails, it is important to make sure that it is because his level of knowledge is not adequate, not because, for example, he had a severe…
