Teaching Case Design Of Information Technology Course In Senior High School Based On Training Of Computational Thinking

When the concept of computational thinking was introduced in 2006,it caused a huge reaction.Computational thinking is a basic ability of learners in the rapidly developing information society.High school students' thinking ability is developed rapidly,they have the computational thinking,they can better deal with all kinds of challenges in the information society.Computational thinking is listed as one of the four elements of information technology discipline core literacy,and it is included in the new version of the information technology curriculum standards.However,in the teaching of information technology in senior high school,the cultivation of students' computational thinking is neglected,but the research on how to cultivate computational thinking in the course of information technology is not much.Therefore,based on the information technology curriculum in senior high school,this study puts forward a research topic of teaching case design based on the cultivation of computational thinking.After deeply understanding the theory of computational thinking,the present situation and the theoretical basis of thinking teaching,this study combines with the information technology curriculum of ordinary senior high school and reflects the cultivation of computational thinking.Selecting specific content for teaching design and implementation,in order to cultivate computational thinking.Specifically,the following aspects of research are carried out:Firstly,in the course of information technology the significance of the cultivation of computational thinking and the present research situation at home and abroad are analyzed and discussed in senior high school.Secondly,the definition of computational thinking is combed and the characteristics and methods of computational thinking are expounded.What'smore,the theoretical basis of thinking cultivation is analyzed.Thirdly,analyzing the teaching design based on the cultivation of computational thinking,it includes the analysis of the curriculum standards of information technology in senior high schools,the embodiment of the cultivation of computational thinking,the selection of teaching contents,teaching methods and the comparison with the traditional teaching design.Fourthly,the teaching design and implementation based on the cultivation of computational thinking are carried out in Chart processing and enumeration algorithms and Program realization.Thereby,the implementation effect is analyzed after implementation.According to the operational definition of computational thinking,the training of high school students' computational thinking as the basic point,this study applies the basic method of computational thinking to the teaching of the specific content of high school information technology course to provide a reference for information technology teachers in the teaching practice of computational thinking.
