Research On VB Teaching Mode Of Senior Middle School Based On Computational Thinking

At present, information technology courses focus on teaching thinking, along with the related study of computational thinking, more and more researchers calculate the importance of thinking in the teaching of information technology.Computational thinking is seen as thinking quality of programming modules.High school program of computational thinking in teaching both theory and teaching practice are at the exploration stage,and Computational thinking in programming teaching has not yet been formed the teaching system, further research is needed. How to develop computational thinking teaching VB programming in high school? Is the starting point and the end of the study.Research on the carding based on studies in computational thinking, First of all, clearly computational thinking idea in this study contains:"Analysis", "Abstract" and "Algorithms and Procedures"; Factors affecting computational thinking approach have "Interests in the program","Confidence in problem solving" and"Exchange and Cooperation".Secondly,build computational thinking mode of VB teaching in high school, according to the existing computational thinking teaching practices abroad and teaching practice of programming home.Then, design teaching contents according to the construction of the teaching mode. Finally, select the study class for the action research, through classroom observations, interviews, and reflections on the teaching mode of high school VB based on Computational thinking to be amended.Study select h grade XX class in Nanjing to do teaching experiments, after the assignment statement, the conditional statement and looping statement three rounds of action research,get three sets of data for statistical analysis, which can be used to show the validation of computational thinking developments.After analysis, its findings as follows:(1) before and after the experiments, students of computational thinking scores are significantly improved. (2) before and after the experiments, the students "analyze" capabilities significantly improve; students "abstract" capable of significant gains; "algorithms and procedures" no significant capability upgrade, but the upward trend.(3) change in student attitudes toward programming, in:students Begin to be interest in programming class; to appreciate the cooperation and exchanges; to be confidence in independent problem-solving and higher demands on the classroom.From the teaching effect of computational thinking and the smooth progress of computational thinking in the teaching process of action research,Using a combination of testing questionnaires and interviews, classroom observations, from quality and quantity has been explained the feasibility of computational thinking teaching mode of VB teaching in high school.But teaching mode in the teaching is not immutable, which need to be adjusted according to the situation. Studies suggest that people should pay attention to knowledge intensive in the teaching process grasp the pace and depth of the discussion in the classroom; classrooms should give students enough time to experience, getting "Personally doing experience";teaching mode link should be in the order you want to adjust.
