Research On Construction And Application Of Design-based Learning Model For Scratch Programming Course In Primary School

With the rapid development of information technology,training innovative computer talents has become an important goal in the field of computer science education.For students living in the digital age,learning programming knowledge alone is not enough to cope with the development of the information age.It has become the goal of the course to cultivate computing thinking and information literacy from programming learning,which is also a higher requirement for students in the information age.Teaching mode is the main teaching activity guidance tool of programming course.Some researchers focus on building appropriate teaching mode to guide students' programming process and help students solve the problems encountered in programming.In the field of primary school education,the popularization of scratch programming course provides a suitable teaching environment for the cultivation of primary school students' computing thinking,and needs an appropriate innovative learning mode to guide teaching.With its unique value of design and creativity,design-based learning mode has attracted more and more researchers' attention.This research first combs and analyzes the domestic and foreign related literature on the design-based learning mode,mainly to understand its theoretical basis,development status,etc.,to lay the theoretical foundation for the later research and experiment implementation;then,constructs the design-based learning mode for the primary school scratch programming course,carries on the teaching design,because the experimental object involves the scratch game design for the first time,therefore There are three stages in the teaching,namely "scratch basic teaching","simple game imitation" and "creative game design".The first two stages are mainly to help students to be familiar with scratch software and understand how to design games by teaching knowledge and imitating games.Finally,in the "creative game design" stage,using the design oriented to the primary school scratch programming course The learning mode carries out teaching,through the design of projects,let students really design games,collect and sort out the relevant data of students in the process of designing games,observe the students' classroom performance,and provide data support for the verification of teaching effect.Based on the above work,this study has achieved many research results.First of all,this study constructs a design-oriented learning model for the primary school scratch programming course.The main body of the classroom becomes students,and the teacher becomes the helper of the students' knowledge construction.It encourages students to design the scratch games independently,while reflecting the students' innovative thinking and design thinking.Second,this study uses the design-oriented learning model for the primary school scratch programming course in the scratch course Carry out teaching,encourage students to design game works,learn programming knowledge,develop creative ideas,and pay attention to problem-solving in real situations;finally,carry out comprehensive evaluation on the whole design process and design works of students,and comprehensively discuss the teaching effect of this mode from two aspects of problem-solving ability and students' works,so as to provide guiding suggestions for later teaching.
