The Curriculum Case Design Of Micro:bit For Computational Thinking Of Elementary School Students

The concept of computational thinking first appeared in the computer field and is often closely related to programming,algorithms and artificial intelligence.With the passage of time,computational thinking has gradually come into the sight of educational researchers and become a hot research topic.Computational thinking,experimental thinking and scientific thinking are the world’s three major thinking,marking the continuous progress of mankind.This basic skill must be mastered in the new age,but at present it seems that most of the development of computational thinking takes place in some area of higher education,such as the university computer foundation course.In order to better meet the various challenges in the world,it is urgent to train students’ computational thinking from the basic education stage.After a comprehensive analysis of the current situation of basic education and the development of computational thinking in China,domestic scholars proposed to set up corresponding robotics courses,maker education and STEAM education in the compulsory education stage by using the information technology classroom as the carrier,so as to develop students’ computational thinking.But the problem is being presented caused by most schools are not really recognize the importance of the teaching content is not reasonable and the teaching evaluation of lax,there is no a set of complete and feasible curriculum standard,at the same time to win the robot contest against the utility for the purpose of teaching activities for the purpose of the robot education,students gained what ability also does not have the corresponding embodiment.The formation of computational thinking is a long process.From the perspective of developmental psychology,children begin to develop their thinking ability at an early stage and continue to develop until adolescence.The training of thinking takes a lot of time.Based on this research,with the core idea of cultivating primary school students’ computational thinking as the core,a set of Micro:bit computational thinking training course for primary school students was designed with the help of Micro:bit open-source hardware as the teaching platform,aiming to solve the problem of the lack of the curriculum system of computational thinking training in primary and secondary schools.The main contents of this study are as follows:(1)This paper has sorted out relevant literatures on computational thinking at home and abroad,integrated the concept of computational thinking,summarized the core elements of computational thinking,analyzed the basic situation of robot research and graphical programming in China,and concluded the feasibility of cultivating computational thinking with Micro:bit as the carrier.(2)The curriculum development framework based on ADDIE teaching mode is designed,and the detailed curriculum design is carried out based on 4I mode.At the same time,the relevant core elements of computational thinking were analyzed,and the basic elements corresponding to them in the basic knowledge of Micro:bit were found,which were reflected in the course content,teaching objectives and teaching activities of each section,so as to guide students to use computational thinking to think and solve relevant problems.(3)Through the research and analysis of the graphic programming and computational thinking evaluation tools at home and abroad,a suitable and effective method for elementary school students’ computational thinking evaluation is designed.In addition,questionnaire survey was conducted before and after the teaching of the actual course,as well as interviews after the course and diversified evaluation methods of standardized tests were evaluated in all aspects to verify the effectiveness of the course.
