App Inventor Course Design And Case Development For Primary School Students

With the development of society,it is urgent to popularize computer science knowledge and skills in the field of education,such as artificial intelligence.Programming is the basis and core of AI,and it has a great promoting effect on the cultivation of students' information technology literacy and computational thinking.App Inventor is a visual online programming tool using drag-and-drop operation.It makes use of the convenience of block language,greatly reduces the threshold of programming learning,and makes it easy for pupils to master and use,"App Inventor Programming" course into primary school is the general trend.Most of the existing books and videos about App Inventor programming are suitable for junior high school students and college students with strong abilities to study independently,and the course resources of App Inventor programming for primary school students are few.This paper combs out the objectives and contents of App Inventor Programming course suitable for pupils according to the curriculum standards of program design in primary school.In view of the limited learning resources of App Inventor case teaching,considering the learning characteristics of pupils comprehensively,based on the evaluation criteria of "Google National Primary and Secondary School Students Computing Thinking and Programming Challenge Competition",the award-winning works over the years are analyzed.To enrich App Inventor case resources,the content suitable for pupils' learning is screened from three dimensions: basic,applied and interesting,which is regarded as an important supplement to the content of App Inventor Programming.The main work of this study is:(1)Analyse the current teaching content of App Inventor Programming at home and abroad,sort out the basic knowledge and operation methods of App Inventor,and design the curriculum for the teaching objectives of domestic primary school students' programming course.(2)Analyse the award-winning works in the "Google National Challenge Competition of Computing Thinking and Programming for Primary and Secondary School Students" in recent years,sort out knowledge points,select cases suitable for primary school students,integrate them into the designed curriculum,and form the content of "App Inventor Programming" course suitable for primary school students.(3)Develop the teaching case of App Inventor Programming and related technical documents,PPT,video and other resources,and test the teaching practice.(4)Design the teaching mode of App Inventor programming based on constructivism,test the practicability of teaching content and mode in teaching practice,and put forward further suggestions.
