Model-Based Thinking and Practice A Top-‐down  Approach  to  Computational  Thinking

In this paper, we discuss using models and modeling in a new way to teach basic computing to pupils within the K-12 segment. We argue why we believe understanding and creating models are fundamental skills for all pupils as it can be characterized as the skill that enable us to analyze and understand phenomena as well as design and construct artifacts. We also try to characterize the essence of model-based thinking and practice. We propose that a strong focus on the relation between mental models (of real or imaginary systems) and computerized models (embedded in computer-based systems) could provide a new approach to teaching computing. This approach should clarify and make explicit the role of models in computing in connection with other subject areas. We believe that such an approach would strongly broaden the participation in computing, as it will allow more pupils to become active creators with computing.
