It explores the use of abstraction in context (AiC) theory as a tool for the analysis of the epistemic actions involved in these processes. We follow a qualitative methodology based on design experiments, focusing on a study carried out with mathematics and engineering students. The analysis allowed us to combine the two models derived from the epistemology of mathematical backward reasoning and AiC theory in a unified framework that allowed us to focus both short-term and long-term processes in mathematical activities. Recurring patterns of epistemic actions were identified. 2227-7390 10.3390/math8060989 https://hdl.handle.net/20.500.14352/8384 https://doi.org/10.3390/math8060989 https://www.mdpi.com/2227-7390/8/6/989 Backward Reasoning and Epistemic Actions in Discovering Processes of Strategic Games Problems
