Theoretical Computer Science, 2017 A model is an interpretation of the symbols of a theory which satisfies the axioms. This gives rise to the class of models for a theory which can be turned into a category with the associated model morphisms. But here may be some difficulties associated with this straightforward looking approach. Look at topological spaces, which may be specified among

Form flows function: Learner‐centered game Re‐design in a STEM classroom
British Educational Research Journal, EarlyView.Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Logic and Logical Philosophy, 2022 The axiom of canonicity was introduced by the famous Polish logician Roman Suszko in 1951 as an explication of Skolem's Paradox (without reference to the L\"{o}wenheim-Skolem theorem) and a precise representation of the axiom of restriction in set theory proposed much earlier by Abraham Fraenkel.
