Teaching Strategy for High School Information Technology Courses Aiming at the Cultivation of Computational Thinking: Take Building a Small Information System as an Example

Computational thinking is one of the four core competencies of the general high school information technology curriculum. When implementing the teaching of Compulsory 2 Information System and Society, front-line teachers often are struggled to the way how teach students well to develop of computational thinking. Through the combing of the eight levels of Gagne’s learning theory and the connotation of computational thinking, combined with the foothold of computational thinking training in the Compulsory 2 module, a “Four Stage Cumulative Learning” strategy for building a small information system is proposed. The training in the module provides an exploratory teaching design idea and implementation strategy.
