Usability, learning, and subjective experience: user evaluation of K-MODDL in an undergraduate class

Based on the CIAO! framework, this paper describes the initial evaluation of the Kinematic Model for Design Digital Library (K-MODDL), which is being used in an undergraduate mathematics class. Along with revealing general usability problems, our results describe users´ subjective experiences and highlight the usefulness of various physical and digital models in facilitating learning. Interesting relationships among usability, learning, and subjective experience were discovered.
