Research On Teaching Design And Practice Of Scratch Programming Education For Primary School Students Face To Computational Thinking

In the information age,the country pays more attention to the cultivation of innovative talents.Computational thinking,as one of the three major scientific thinking,has a distinct characteristic of the times and has received widespread attention.Many countries have included computational thinking in the curriculum of information technology,My country is based on computer science,basic literacy and information technology.Computer-based research in the field of computer science in the country and abroad,cultivating the computational thinking of college students,and then the research on the cultivation of computational thinking gradually entered primary and secondary schools.In recent years,Scratch programming has entered elementary school information technology textbooks in various provinces and cities,but there are still a series of problems in teaching and training methods such as focusing on operation and neglecting thinking,and there is still a gap between ideals and reality.For this reason,this research takes primary school students as the research object and Scratch classroom teaching as the carrier to construct a task-driven teaching model in order to cultivate students' computational thinking.This study systematically summarizes the current research status of computational thinking and Scratch teaching at home and abroad by searching for relevant documents,determining the research content and designing a research idea map.Then define the core concepts,based on Piaget's cognitive development theory,Vygotsky's recent development area,and Theory of task-based learning studies the design of Scratch elementary courses aimed at the development of computer thinking,and the teaching aims and context.The main design of teaching resources,teaching models,and teaching evaluation.The context of the design applies the framework of assessment of computational thinking as a learning objective and establishes a functional educational model of teaching computer thinking from decomposition,pattern recognition,abstraction,algorithm and automation The five competence dimensions cultivate computational thinking,and the evaluation methods of international computational thinking test questions and interview surveys are used to evaluate the teaching effect.Finally,this research selects four classes of students in the sixth grade of XC Primary School in Changsha City as the research objects.According to the different teaching modes,they are divided into experimental classes and control classes to conduct teaching practice and evaluate the improvement of students' computational thinking level.The consequences of the study reveal that the learning regime is the highest thinking.The standard of computer literacy of the experimental class was higher than that of the control group.The hands-on class improves computer thinking skills in a variety of areas,especially analytical and algorithmic skills.The growth is higher.
