Research On Cultivation Strategy Of Computational Thinking In Information Technology Teaching In Senior High School

Since Professor Zhou Yizhen first proposed the definition of computational thinking in 2006,scholars at home and abroad have carried out relevant studies on computational thinking.In the Curriculum Standards of Information Technology for Senior High Schools(2017 edition,2020 revision),"computational thinking","information consciousness","digital learning and innovation" and "information society responsibility" are listed as the four core qualities of senior high school information technology discipline,and the four core qualities are clearly defined.It emphasizes the importance and inevitability of cultivating students’ computational thinking in information technology teaching in senior high school.From the perspective of cultivating students’ computational thinking,based on sorting out relevant researches on computational thinking,this study divides computational thinking into two dimensions,namely attitude of computational thinking and skills of computational thinking,and subdivides it into seven sub-dimensions,namely emotional attitude,cooperative communication,decomposing thinking,abstract thinking,algorithmic thinking,generalized thinking and evaluation thinking.Secondly,the teaching strategy of computational thinking cultivating is constructed;Finally,three rounds of teaching action research are carried out in L school,and teaching strategies for cultivating computational thinking are constantly revised.Finally,effective training strategies for computational thinking in information technology teaching in high school are obtained,which can provide reference for front-line teachers’ teaching.This paper mainly includes five parts:1.Preliminary research and theoretical sorting.Based on the research status,theoretical research and practical research of computational thinking at home and abroad,combined with the definition of computational thinking proposed in Information Technology Curriculum Standards for High School(2017 edition,2020 revision),and taking constructivism learning theory and multiple intelligences theory as the theoretical basis of this study,Seven sub-dimensions of computational thinking cultivating in this study are determined,namely,emotional attitude,cooperative communication,decomposing thinking,abstract thinking,algorithmic thinking,generalized thinking and evaluation thinking.2.Current situation investigation.Based on the teaching situation of L school and the requirements of high school information technology discipline on computational thinking,this study combined with existing research and expert opinions,designed a questionnaire from seven sub-dimensions of computational thinking and interviewed the IT teachers of this school to understand the current level of computational thinking of students in L school,analyzed and summarized the problems that need further improvement in the current teaching of information technology in high school.3.Design and implementation of teaching strategies and action research on the cultivation of computational thinking.Before carrying out the action research,the teaching strategy of cultivating computational thinking is preliminarily constructed,and the first round of action research adopts the preliminary strategy to carry out the teaching.After the first round of action research,the initially constructed strategy should be modified and improved.Meanwhile,Bebras International computational thinking test questions should be used to test students’ computational thinking,followed by the second and third rounds of action research to gradually modify and improve teaching strategies,and finally,effective strategies for the cultivation of computational thinking in information technology teaching should be summarized.4.Analysis of teaching effect of computational thinking cultivating.The effects of cultivating students’ computational thinking were analyzed by means of questionnaire scale pre and post test,interview method and Bebras international computational thinking test questions after each round of action research.5.Research summary and prospect.Summarize and refine the results of this research and draw the conclusions of this research,reflect on the shortcomings and problems in the process of research,and make prospects for further research.The conclusions of this study are as follows:The final conclusions are as follows: Creating situational items close to daily life is conducive to stimulating students’ learning motivation;Pay attention to teachers’ guidance and group cooperation;Making full use of visual tools can improve teaching and learning efficiency;Diversified feedback evaluation can promote the development of students’ computational thinking.All in all,after applying the training strategy of computational thinking in high school students,the training strategy can effectively improve the level of students’ computational thinking.
