Scratch Instructional Design And Practice Based On Reuse And Reinvention

Recently,the State Council issued "a new generation of artificial intelligence development plan",put forward the implementation of universal intellectual education project,set up artificial intelligence courses in primary and secondary schools,and gradually promote programming education,encourage social forces to participate in entertaining programming teaching software,game development And promotion.Scratch,a children's programming software that is more popular with primary and secondary school students and teachers,has been gradually introduced to primary and secondary information technology classrooms by teachers.Reuse and remix are everywhere in our lives.It is based on existing things to recreate.The recycling of old things,the cover of songs,the remake of movies,etc.can all be said to be reuse and remix.Programmers have the opportunity to modify existing code snippets to learn programming,which allows them to create more complex programs beyond their own level,encourage students to learn programming while using,modifying,and creating,learn to use programmatic thinking,and solve problems method.The online community has provided programmers with an innovative environment and resources,making it possible for individual programming to go to community programming and personal knowledge to public knowledge.The main purpose of this study is to provide a new teaching method for Scratch teaching.Through the literature analysis and summary of the status of Scratch at home and abroad,through the analysis of online community and the cases of users' works and Scratch teaching cases,the classification and method of reuse and remix,and the teaching model of reuse and remix are summed up.On this basis,the design of Scratch Teaching is carried out.Creativity can be applied to Scratch teaching,which can train students' reading ability,autonomous learning ability and computational thinking ability.According to the teaching practice of this study,the teaching strategies are summarized from the aspects of teaching objectives,teaching forms,teaching auxiliary resources,teaching evaluation and so on,which can be used for reference for the teaching of Scratch.
