Scratch-based Teaching Case Design And Practical Research On The Cultivation Of Primary School Students' Computational Thinking

With the development of information society and the coming of 5g era,artificial intelligence is influencing the development of human thinking mode.It is obvious to all that information technology is beneficial to the development of society.As the core accomplishment of the development of information technology,computational thinking is rising in Europe and the United States.It is considered as a necessary thinking ability for everyone,just like listening,speaking,reading,writing and calculating.In recent years,it has also become one of the hot spots in the field of education in China.Computational thinking has a high degree of concern in Colleges and high school curriculum,but there is little implementation and research in primary school curriculum.How to organize and design teaching in order to effectively cultivate students' computing thinking has become a common concern of educators.According to the current situation of primary school students' Computational Thinking training,this study reviews and analyzes the relevant literature such as keyword computational thinking,scratch,etc.After analysis,and carries out relevant research on teaching case design and practice of primary school students' Computational Thinking Training Based on scratch.First of all,the author designs an interesting interactive teaching mode in combination with the sixth grade information technology course of the internship primary school;second,scratch,as a teaching method,carries out a semester of teaching practice activities to cultivate primary school students' computing thinking.Each teaching activity is divided into: preparation before class,establishment of concepts;creation of context,clear purpose;collaborative exploration,sorting out problems;creation of items Objective: To explore,share and exchange in practice,display works,and analyze the teaching practice effect of training primary school students' Computational Thinking Based on scratch according to the feedback of teachers and students' behaviors.At last,we use many kinds of analysis methods to analyze the practical effect,and verify the improvement of primary school students' Computational Thinking.Based on the practice research and the principle of triangle mutual proof,this paper analyzes the students' classroom observation,questionnaire and interview,formative practice,work analysis and presentation report,especially in the form of presentation report,which shows the multiple sub goals of students' computing thinking about computing concept,practice andconcept.By different analysis methods,it can be concluded that System learning,learners' computational thinking has been greatly improved to ensure the effectiveness of the conclusion.In solving the difficulties,students can take the time to do well,cooperate with their classmates actively,express their ideas clearly and adapt to the development of modern society better.
