Computational thinking implemented in five sets of high school information technology textbooks in mainland china: Comparative study of methods and strategies

The rapid development and popularization of information technology has changed people's behavior and thinking characteristics. Among them, computational thinking is considered to be an indispensable basic ability in life, and computational thinking has been identified as the core literacy of the information technology discipline at the K-12 stage. Implementation and teaching methods are of concern to educational researchers and front-line teachers. Based on the development of computational thinking and computational thinking education, this article focuses on the core concepts and training methods of computational thinking, and refers to the 2017 high school information technology curriculum standards in China, and determines the teaching materials to implement calculations from the orientation and training methods of computational thinking. The four dimensions of thinking are used to compare the implementation of computational thinking in 5 Chinese textbooks, and corresponding teaching suggestions are provided to provide theoretical and practical references for the cultivation of computational thinking in students.
