Expressing Adaptations to Take into Account in Generator-based Exercisers: An Exploratory Study about Multiplication Facts

This paper intends to explore how the generation logic and the elements involved are expressed from the teachers' viewpoint, in the context of learning games. We present an interview-based exploratory study: preparation, realization, analysis, and findings. From the results we also propose a dedicated metamodel to capture these expressed elements and logic. We evaluate this metamodel by developing a high-level generator component about the practice of times tables.
