Rresearch On The Cultivation Of High School Students' Computational Thinking In Thematic Teaching

Computational thinking is the key literacy of people in solving problems,and also the key to improve students' adaptation to the survival and lifelong development of information society.In order to better meet the new expectations of the information society for the development of students,how to reasonably train students' computational thinking in information technology classroom teaching is a key daily task.There are many ways to train students' thinking of calculation.Classroom teaching based on the theme style is the whole process of completing the overall goal of the theme style based on solving difficulties and actively advancing.Therefore,for the current situation of classroom teaching,the article clearly puts forward the key scientific research problem of "how to organize special lectures in classroom teaching to reasonably shape the students' calculation thinking logic".Take constructivist theory learning theory,multiple intelligence basic theory and activity theory as the basic,and take the general high information technology syllabus as specific guidance(2017 Edition),the subjectbased teaching activities are designed for Data and Calculation(Teaching Section).The design of the activity mainly includes activity theme,activity goal,activity resources,activity mode and activity evaluation.The theme of activity focuses on the connection with students' life reality;the activity goal is formulated from three aspects of Computational Thinking(calculation concept,calculation practice and calculation concept);activity resources include basic and extended resources;activity include problem analysis,algorithm design,compilation and debugging,and optimization of works;activity mode includes the activity inquiry which focuses on problem solving.Evaluation is based on the combination of qualitative and quantitative evaluation metgod for the student to carry on the comprehensive evaluation.This study adopts action research method to carry out three rounds of thematic teaching activities,analyzes the changes of learners' Computational Thinking in the teaching process,and to verify the effectiveness of theme-based teaching in cultivating students' computational thinking.Take constructivist theory learning theory,multiple intelligence basic theory and activity theory as the basic,and take the general high information technology syllabus as specific guidance.According to the feedback data information of each classroom teaching practice activity,the paper summarizes the application strategies of theme teaching activities.According to the data results of students' pre and post calculation thinking,interview results,classroom observation results and paper pen test results,through the analysis of students' learning effect,found that students are no longer limited to the basic knowledge of students' programming,but also can innovate their works,summarize the process and methods of solving problems by computer,and transfer them to the relevant problems solving.
