Study On Teaching Design Of Scratch Course In Elementary School Based On Computational Thinking

With the rapid development of science and technology,more and more information technologies are pouring into people's lives.The "Thirteenth Five-Year Plan for National Education Development" pointed out that modern technology has profoundly changed the way people think,produce,live and learn.China's "Ten-Year Development Plan for Educational Informatization(2011-2020)" emphasizes the improvement of students' ability to ask questions,analyze problems and solve problems in the teaching process.The 2017 "Horizon Report(Basic Education Edition)" also pointed out that the cultivation of computational thinking in elementary and middle school students is an important topic in the 21 st century.Computational thinking should be another aspect of students' daily life in addition to reading,writing and computing.Basic skills that must be mastered.Computational thinking,as a way of thinking,is a long-term process of cultivation and formation.Then primary school,as the initial stage of basic education,should develop computational thinking into a universal ability for digital survival."2019 Education Informatization and Network Security Work Points",proposed to "promote the establishment of artificial intelligence-related courses in the primary and secondary schools,and gradually promote programming education." Scratch is a visual building block-oriented programming design software for teenagers,which is convenient for primary school students to learn and use.Therefore,how to integrate the cultivation of computational thinking into the creation of Scratch works,so that students can gradually improve computational thinking through the learning of Scratch courses Awareness is a problem that needs to be studied urgently.This research firstly uses the literature research method,with reference to domestic and foreign computational thinking and related research of elementary school Scratch courses,to analyze and comb the teaching status of elementary school Scratch courses.Scratch as a visual building block programming tool is beneficial to the actual teaching process Cultivate students' computing thinking ability.China's cultivation of pupils' computational thinking is still in the exploratory stage.Through investigation,it is found that in the current stage of primary school information technology curriculum teaching,emphasis is placed on the cultivation of knowledge skills and the neglect of the cultivation of computational thinking ability.insufficient.Secondly,with the support of constructivist learning theory,"doing high school" theory and Piaget's cognitive development theory,an elementary school Scratch curriculum teaching design based on computational thinking was constructed.The teaching design designed the teaching activities based on the Scratch project through the early analysis stages such as learner characteristics analysis,teaching content analysis,and front-side analysis of the students' calculation thinking level.The students carried out purposeful learning by completing the teaching activities arranged by the teacher.Finally,the instructional design was applied in the practical teaching of a class in the sixth grade of an elementary school,and the back analysis of the computational thinking level of the students was analyzed.The comparison of the survey data before and after the computational thinking verified the teaching The effectiveness of the design realizes the cultivation of the students' computational thinking ability by the instructional design.Based teaching of elementary school Scratch course,in order to improve the students' consciousness of computational thinking as the key point,in the actual education teaching process,by the method of internalization of computational thinking,make the students thinking about making his work at the same time,can train and cultivate students' thinking ability,suitable for calculating primary Scratch course teaching design of cultivating the ability of thinking,so as to achieve the purpose of computing thinking ability of students,make subject knowledge and thinking ability enhancement,promote each other,To some extent,it proves that the teaching design of Scratch curriculum based on computational thinking can effectively improve students' computational thinking ability,and has a positive impact on the teaching effect of Scratch curriculum in primary schools,so as to promote the cultivation of computational thinking in primary schools in China.
