RT Journal Article T1 Measuring Procedural Knowledge in Problem Solving Environments with Item Response Theory A1 Hernando, Manuel A1 Guzmán-de-los-Riscos, Eduardo Francisco A1 Conejo-Muñoz, Ricardo José K1 Resolución de problemas - Proceso de datos AB In this paper, a new data-driven model to measure procedural knowledge is described. The model is based on Item Response Theory. The main idea behind this new model is to establish an analogy between the testing and the problem solving environment. For this purpose, we model each problem (or exercise) solution path as a directed graph where nodes are states of the problem and edges, transitions between states (i.e. the actions accomplished by the student). We can match this model with testing by seeing each node as a question and each edge as choices within the questions.
