Research On The Application Of Question Feedback Strategies Based On Mind Maps In High School Information Technology Classrooms

Project-based leaming(PBL)is a teaching model based on constructivism and widely used in information technology courses.PBL requires students to have strong knowledge understanding and problem exploration ability,but in the process of project implementation,students often have unclear thinking,difficulty in operation,poor ability to use knowledge,etc.In the process of communication with teachers,most students have not been timely solved or even failed to solve the difficult problems encountered in class due to many factors,such as the single way of asking questions and feedback,and the defective way of resource presentation.As the project type teaching has become the mainstream in the teaching method in many schools,adopt the appropriate means and methods to enrich and improve the project type teaching of the teacher to student's problem feedback strategy,thus to effectively solve the problems of the students in the classroom becomes more and more important.Mind mapping is a visual tool that has a unique educational effect on the organization of classroom information,resources and thoughts.This thesis attempts to introduce mind mapping into the feedback link of high school information technology project-based teaching.Based on classroom observation,questionnaire survey and interviews with teachers and students,it investigates the current situation of students' questions and teachers' feedback in information technology project-based teaching.Then,it designs strategies for the feedback link of teachers'questions in project-based teaching,sorts out the factors influencing teachers' feedback,designs feedback strategies based on mind mapping.by collecting relevant data of students' motivation and cognitive load in control class and experimental class,comparing the above results through data analysis,and interviews and learning satisfaction surveys,to understand the learning experience of experimental class students after practicing the problem feedback strategy,and to explore the strategy implementation of the effects of the project type teaching to the student for the project type teaching in teachers' feedback problem for students to explore new train of thoughtThis study to the theme of "creative lamp" project as an example,the selection of W,S high school senior grade two classes of students for specific research object,for six weeks of project teaching in the teaching practice.Data results show that:before and after the feedback strategy based on mind mapping problem feedback strategy can improve the students' learning motivation,reduce the cognitive load of students,to improve the effect of teaching with student project has obvious effect,because the strategy enriched questions and feedback to facilitate teachers understand the difficulty of students in many aspects.Secondly,as a way to support problem feedback,mind mapping can optimize the ways and methods of analyzing and dealing with problems,make students analysis ideas more logically,feedback problem content more shared,and solve problems more diversified.
