High School Information Technology Based On Big Idea Instructional Design And Practice

The Curriculum Standards for Information Technology in Senior High Schools(2017 Edition,2020 Revision)(hereinafter referred to as the Curriculum Standards)clearly put forward four core concepts in senior high school information technology teaching,and the inclusion of major concepts in the curriculum standards fully reflects the importance of big concepts to the implementation of core literacy.The indepth curriculum reform of primary and secondary schools depends on the direction of core literacy,while the concept of subject puts forward clear curriculum content and core structure,and provides operable direction for curriculum optimization.Through literature research,action research,classroom observation,questionnaire survey and interview,this study applies the teaching mode based on big concepts into the information technology curriculum of high school,striving to change some teachers’ misunderstanding of big concepts,improve the teaching quality of information technology,and implement the core literacy of information technology discipline.Enrich the research results of the application of big concept theory in subject teaching and promote the implementation of big concept in information technology curriculum teaching.First of all,this paper combs the relevant researches on big concept teaching at home and abroad,and summarizes the connotation and significance of big concept from the theoretical level.Secondly,by exploring the theoretical and practical research models of big concept theory in curriculum design and subject teaching,we find out the big concept teaching model suitable for practice teaching.Thirdly,by analyzing the curriculum standard,we summarize the correlation between the big concept of subject and the core literacy of subject,and analyze the value and significance of information technology teaching based on the big concept of subject at present.Finally,a teaching model of information technology in senior high school based on big concept of subject is constructed.This model is generally divided into four aspects: overall planning of big concept of information technology teaching-planning of big concept of information technology teaching objectives-design of big concept of information technology teaching evaluation-design of big concept of information technology teaching process.On the basis of theoretical research,three rounds of education action research on information technology in high school based on the concept of discipline were carried out.The research data were collected through classroom observation,questionnaire survey and interview,and the effect analysis was carried out.Finally,the following research conclusions were drawn:The teaching mode of information technology in high school based on the big concept of subject can provide students with new learning methods,promote the construction of logical system of information technology subject knowledge,cultivate students’ learning ability,improve the development of computational thinking in abstract thinking,algorithmic thinking,decomposing thinking,problem-solving thinking and other levels,and promote the improvement of students’ core literacy of subject.
