Research On Scratch Jr Programming Instructional Design For Senior Class Children

With the arrival of the era of artificial intelligence,the State Council clearly pointed out in the "New Generation AI Development Plan" that programming knowledge as a necessary knowledge literacy for development needs to be highly valued.Infant programming has been regarded as a skill with equal status as reading and writing.Programming is to use a systematic way to create commands for digital expression to complete the task.Previous studies have shown that Scratch Jr as an enlightenment programming software developed for 5-7 year old children can help young children learn how to apply programming thinking in games,so as to solve problems efficiently..At present,there are some common problems in children's programming teaching: for example,programming learning needs to pay high tuition fees,uneven teacher levels,unclear teaching goals,imperfect teaching modes,no levels of structure,and lack of gradual improvement in operation gradients.Jr programming teaching model and test the effectiveness of this model in practice.In this study,12 large class children who have not been exposed to programming knowledge in the internship's park are taken as the research object,and the purpose is to cultivate their programming thinking to promote the development of independent problem solving and other capabilities.The author proposes a Scratch Jr programming instructional design for children.The teaching content is set up as a three-stage course.The action research method is used to test the design.On the basis of practice,a set of Scratch Jr programming instruction models suitable for children is summarized.The specific main work carried out is as follows:(1)Through the analysis of the collection of domestic and foreign literature on Scratch Jr programming,summarize the current research status of Scratch Jr programming.Analyze the feasibility of implementing Scratch Jr programming teaching in kindergarten,and put forward the concept of "Scratch Jr programming is suitable for the development of young children".(2)Design Scratch Jr programming teaching objectives,strategies,content,steps,and try to build Scratch Jr programming teaching mode.(3)Record and analyze the three rounds of Scratch Jr programming teaching practice through action research,combined with the interview method to understand the learning situation of the children and adjust the teaching to the teachers and parents in class The research results of Scratch Jr programming teaching show that Scratch Jr can effectively develop children's problem thinking,algorithmic thinking,critical thinking,cooperative thinking and innovative thinking,and help children improve their communication skills,independent analysis ability and summary ability;The construction of the "concrete-random" Scratch Jr programming teaching model enriches the theoretical content of children's programming teaching,and provides a reference for subsequent children's teaching programming.
