Research On Instructional Design Strategy Guided By Computational Thinking

Since Professor Jeannette M,Wing put forward "Computational Thinking" in 2006,it has gradually become the focus of domestic and foreign scholars.In 2018,it clearly lists "computing thinking" and "information consciousness","digital learning and innovation" and "information social responsibility" as the four core literacy in the" Senior High School Information Technology Curriculum Standard".This shows that in the high school,the front-line information technology teachers need to cultivate students'computational thinking ability,which is one of the core objectives of teaching.According to the research on "Computational Thinking",the course "algorithm and program design",which has been offered in senior high school,is conducive to the cultivation of students' Computational Thinking.In order to provide some reference for the front-line information technology teachers in instructional design,the author has carried out a research on instructional design strategy guided by computational thinking——Taking algorithm and program design course as example.Based on he full understanding of the concept computational thinking,the research background,and the current status of research at home and abroad,this study thoroughly analyzes the teaching content of the course algorithm and program design,combined with task-driven teaching method,fully considers the difficulties of front-line information technology teachers in instructional design,puts forward task-driven instructional design strategy guided by computational thinking,and explains task-driven instructional design strategy in detail.In the task-driven instructional design guided by computational thinking,it integrates the relevant methods,learning guidance plan and group cooperation mode of computational thinking in each link of task-driven teaching.Its purpose is to give full play to the leading role of teachers,make teachers easy to control the teaching process,reduce the difficulty of teachers in instructional design,and fully cultivate students'computational thinking ability.Embracing the hope for investigating the effectiveness of strategy and offer more reference to the front-line teachers the author combined the task-driven instructional design strategy guided by computational thinking with specific teaching content in the course of algorithm and program,therefore,obtained two instructional design cases.Based on the cases,The author conducted one-month teaching in a high school,and the outcome further confirmed the effectiveness of the strategy.During the practice,the author gradually revised and improved the instructional design cases,and finally made the cases more mature and effective,which provides the reference for frontline information technology teachers in the instructional design process.Finally,through the above research,this paper summarizes and refines the research results,puts forward some suggestions for the front-line information technology teachers to use this strategy for instructional design and practice,and also objectively analyzes the limitations of this study,and makes a prospect for the future research...
