Phys. Rev. ST Physics Ed. Research 3, 020107 (2007) [8 pages]Applying clustering to statistical analysis of student reasoning about two-dimensional kinematicsSee Also: Erratum
We use clustering, an analysis method not presently common to the physics education research community, to group and characterize student responses to written questions about two-dimensional kinematics. Previously, clustering has been used to analyze multiple-choice data; we analyze free-response data that includes both sketches of vectors and written elements. The primary goal of this paper is to describe the methodology itself; we include a brief overview of relevant results.
