Practical Research On The Cultivation Of Elementary School Students' Computational Thinking Based On Scratch Programming

In the information society,creative computing thinking ability is the need of the society and one of the basic skills everyone should have.Today,computing become an important concept of thinking,is more and more extensive concern to the international computing and education,through computing and education elder people a lot of research and experimentation,program design course in information technology can effectively reflect the develop process of computational thinking,so in the program design course of information technology to cultivate students thinking ability is of great significance,at the same time calculation of thinking into the program design course in information technology classroom practice and reform also plays an important role in promoting.Therefore,how to cultivate students' computational thinking ability has become a top priority issue.In China,the cultivation of students' computational thinking is generally in the basic course of computer science in universities.However,with the rapid development of informatization,everyone should have the ability to process various kinds of information,and the cultivation of this ability should be grasped from children.Therefore,to improve each student's information literacy has become the primary and secondary school information technology course training goal.However,in the specific implementation process,although some achievements have been made,they are still not very satisfactory,because the teaching content is mainly about basic computer operation methods and the use of office software,which cannot arouse students' interest in learning,let alone cultivate their ability to handle various kinds of information.In recent years,a children's programming software called Scratch,developed by the MIT media lab,has caught the eye of primary and secondary school teachers,who have come up with a brilliant,easy-to-use interface that blends many media formats with a few small ideas.The students also loved the scratch programming software.The purpose of this study is to cultivate the computing thinking ability of the fifth grade students in primary school through the specific implementation of Scratch programming software teaching.Based on the author scratch course calculation of primary and middle school students in the context of the cultivation of thinking ability mainly conducts research in the following six aspects: the first part of this subject research significance,the research background,research content,and the research method adopted by the introduces the author's research process and the implementation plan,from the big progress of the study on the level of the introduction of a whole.The second chapter briefly introduces what is computational thinking,analyzes the research status of computational thinking,and sorts out the characteristics of computational thinking.Then,we analyzed the Scratch software and its characteristics,and found the intersection between computational thinking and Scratch software.It lays a foundation for the cultivation of elementary school students' computational thinking in the follow-up scratch teaching.In the third chapter is mainly based on scratch course to cultivate students thinking ability of the related theory has carried on the summary analysis,such as humanistic theory,constructivism learning theory and STEAM related theory and classroom practice will use mind mapping,etc.,for below scratch in classroom teaching to cultivate students laid a theoretical basis for the calculation of thinking.In chapter 4,we propose a teaching design model based on the calculation thinking of primary school students in scratch teaching.It includes teaching environment,research object analysis,teaching content analysis,teaching objective analysis and teaching strategy formulation.In addition,the design of teaching implementation link and classroom teaching evaluation was carried out by combining the features of Scratch software.The fifth chapter mainly combines the teaching design model of primary school students' computational thinking training based on scratch proposed in the fourth chapter,and makes a time study with two practical cases of classroom teaching: "through the maze" and "big fish eats small fish".And achieved certain result.Chapter six summarizes and prospects the thesis.
