Design And Application Of High School Information Technology Learning Scaffolding Based On Project-based Learning

In order to meet the development requirements of the times,realize the needs of education informatization and the cultivation of talent quality.In 2020,the Ministry of Education revised the "General High School Information Technology Curriculum Standards(2020 Edition)",emphasizing the use of project-based learning teaching methods,allowing students to pay equal attention to theoretical learning and practical application,using digital tools to solve real-world problems,in communication and sharing.cooperation and negotiation in the learning process to improve the level of information literacy.In the project-based learning process,students' independent inquiry and deep thinking are dominant.Teachers should correctly guide students to solve problems in the teaching process of project-based learning.The learning scaffold is an auxiliary tool in the teaching classroom,which is helpful for teachers to provide guidance and students' knowledge construction.This coincides with the needs of information technology disciplines.After reading a large number of related literatures on project-based learning and learning scaffolding at home and abroad,this research focuses on integrating the characteristics of information technology disciplines on the basis of the learning scaffolding proposed by research scholars,and proposes specific functions and manifestations.This paper analyzes the teaching links of project-based learning in high school information technology classrooms,builds the designed learning scaffolds in different teaching links,and clarifies the role of learning scaffolds in project-based learning teaching links.Taking constructivist learning theory,zone of proximal development theory and meaningful learning theory are used as the theoretical support for this research.Literature research method,action research method,classroom observation method and interview method are used to conduct practical application reflection summary.It is mainly based on the main courses in the Shanghai science and education version of high school information technology textbooks.Three rounds of action research and iterative revisions are carried out on the learning scaffold designed in the project-based learning.The above research results show that:1.Designing a learning scaffold in the project-based high school information technology classroom will help improve students' interest in learning,stimulate students' learning motivation,help students experience information technology to solve practical problems,and help students master the knowledge and skills of information technology.2.Designing a learning scaffold in a project-based high school information technology classroom can arouse students' in-depth thinking and inquiry,and improve students' teamwork ability,evaluation and reflection ability and ability to solve digital problems.3.Designing a learning scaffold in the project-based high school information technology classroom will help implement all teaching links of project-based learning,help students achieve teaching goals,and help improve students' information literacy level.
