How well do they learn Newtonian Mechanics concepts?

This article presents data on the Force Concept Inventory 2 used as diagnostic test since 2004 in the first year bachelor of Science at the Vrije Universiteit Brussel. Since the academic year 2004-2005, we have administered the Force Concept Inventory at the beginning of the mechanics course, and after the first examination period in winter. The pretest reflects students initial knowledge about force and motion at the moment of entry at university, the posttest is assumed to reflect their understanding after a one semester university course on Newtonian Mechanics. Data spanning nearly a decade are presented.
