Design And Application Of Middle School Scratch Programming Course Based On PBL

With the advent of the era of artificial intelligence,programming education is in the stage of vigorous development.Chinese government has issued a number of documents related to artificial intelligence education,emphasizing the need to start training scientific and technological talents at the state of basic education,encouraging primary and secondary schools to set up programming related courses and popularize programming education.However,due to the unbalanced economic development,Laibin No.11 Middle School has not yet set up courses related to artificial intelligence programming,and has not been able to implement the national information technology curriculum reform policy.Based on PBL teaching mode,this paper designs the middle school Scratch programming course,aiming at implementing the information technology curriculum reform policy and cultivating students' Computational Thinking,providing new ideas for the information technology curriculum reform of Laibin No.11 middle school and enriching the information technology curriculum teaching resources.The specific research contents of this paper are as follows:First of all,combing and analyze the research status of artificial intelligence education in primary and secondary schools.Based on existing experience and research results,the main process of PBL is summarized as follows:selecting theme projects,making plans,exploring activities,producing works,sharing achievements and evaluating works.Secondly,investigate the current situation and demand of information technology curriculum in Laibin No.11 middle school.According to the actual situation of the school,based on the theory of "learning by doing","zone of proximal development"and computational thinking.develop and design the teaching case of middle school information technology Scratch programming course.Finally,according to the scratch programming course content designed in the early stage,the teaching practice research is implemented.Before and after the implementation of the course,the students' Computational Thinking was tested by using Likert's Computational Thinking questionnaire.Use SPSS25 tools to organize and analyze experimental data;use Dr.Scratch website to analyze student works.Through the practical research of Scratch programming teaching based on PBL,it is feasible to implement Scratch programming course in junior high school.?Scratch programming teaching in middle school based on PBL mode improves students' classroom participation,and has a certain role in cultivating middle school students' interest in learning and computational thinking ability.?PBL encourages students to cooperate,explore,share and communicate,which can cultivate the ability of collaboration,oral expression,and the spirit of research and inquiry.?In improving students' creativity,cooperation ability,programming thinking and critical thinking,it has certain reference value for the development of junior high school Scratch school-based curriculum.
