Abstract
This paper focuses on the epistemic and cognitive characterization of backward reasoning in strategy games resolution. It explores the use of AiC (Abstraction in Context) as a tool for the analysis of the epistemic actions involved in these processes. It is reported a first analysis developed by the research team in order to be used as protocol-guide in the analysis of a study carried out with PhD students in Mathematics Degree in a Spanish and an Italian University, who face problem solving games. The case study shows the process of discovery that a PhD student makes to formulate a general recursive formula. It is a key for understanding the interaction between the AiC model and the characteristics of backward reasoning. The analysis allows to combine the two models - backward reasoning and AiC - in a unified framework that allows to focus both short-term and long-term processes in students’ activities.
