Research On Hierarchical Teaching Design And Practice Of Scratch In Primary School

In recent years,with the development of artificial intelligence,the Ministry of education gradually promote programming education,the primary and secondary schools in China are scrambling to open scratch community courses.The corporate classroom is different from the traditional classroom.It gathers the students who are interested in Scratch programming in different grades(grades 3-6).The students' learning background,learning conditions and basic conditions are quite different,this makes it necessary to pay attention to the differences between students in teaching.In order to ensure that the students in the community can make progress and improve on the original basis,this study adopts the idea of layering to design the teaching of Scratch in primary school,cultivating students' ability of calculation thinking and promoting students' individuation development.Based on the theory of the zone of proximal development,the students in the class are divided into groups and the goals are divided into levels,and the detailed graded tasks are designed according to different levels of information technology,step by step to deepen the cognitive level,and then through hierarchical practice,hierarchical guidance,hierarchical evaluation,to ensure that the level of students corresponding to the computational thinking ability.According to the questionnaire survey,the rationality of the students' stratification is ensured,and the scientific nature of the goal stratification,task design and evaluation method is ensured through the interview with experts.The reflection of students after learning and the feedback from it teachers after class showthe feasibility of hierarchical teaching.The research results show that as long as teachers make sufficient preparation before class,the layered teaching can meet the learning needs of students at all levels,improve students' learning enthusiasm,stimulate students' challenge,and tap students' potential,cultivating students' creative ability and aesthetic appreciation ability.The layered teaching can promote the individual development of students.In the classroom teaching,it can meet the needs of all levels of students,improve the enthusiasm of students,stimulate the challenges of students,fully tap the potential of students,and cultivate the ability of innovation and aesthetic appreciation of students.Hierarchical teaching can improve the efficiency of classroom teaching and improve the status of students who are only receivers in traditional teaching.Teachers as guides and supervisors can give different help to students at different levels at appropriate times,to enable students at all levels to gain from the learning process.
