Knowledge components (KCs) have many applications. In computing education, knowing the demonstration of specific KCs has been challenging. This paper introduces an entirely data-driven approach for: (1) discovering KCs; and (2) demonstrating KCs, using students' actual code submissions. Our system is based on two expected properties of KCs: (1)…

The purpose of this design case is to tell the story of our work to design context-aware activity notification for learning management systems. The story of the design experience is not simple, in that it includes research and development, conceptual evolution, implementation and extinction, and multiple phases, including inspiration for future…
