Research On The Construction And Application Of High School Information Technology Project-based Teaching Mode Oriented To Computational Thinking

In order to build a powerful country of science and technology in the world and cultivate innovative talents of science and technology,we must change the educational concept and find the training mode of innovative talents.Computational thinking has become one of the essential core qualities of scientific and technological innovation talents because of its unique subject attributes and problem-solving thinking mode.In the stage of basic education,China advocates adopting project-based teaching as an important way to cultivate computational thinking ability at this stage,and it is urgent to seek a project-based teaching mode that can effectively improve students’computational thinking ability.This paper takes "Project-based Teaching Mode of High School Information Technology Oriented to Computational Thinking" as the research object,adopts the methods of literature analysis,investigation and research,questionnaire survey and so on,constructs the project-based teaching mode of high school information technology,and designs a project-based teaching case aiming at improving students’ Computational Thinking Ability based on this mode,and applies the above case to teaching implementation,Through investigating and recording the implementation of the course and the students’ Computational Thinking Ability in the course of application,the paper puts forward suggestions for teaching implementation,promoting the effective occurrence of computational thinking teaching,and further implementing the training of students’ computational thinking ability.With the method of literature analysis,under the guidance of constructivism theory,situational learning theory and other educational theories,combined with the analysis of the elements of computational thinking,the psychological characteristics and cognitive level of high school students,the traditional project-based teaching mode and the basic principles of the construction of educational mode,the paper links the process of Computational Thinking with the steps of traditional project-based teaching,Find out the project-based teaching steps that can keep consistent with the thinking process of students’ Computational Thinking,get the mapping relationship between the project-based teaching steps and the thinking process of computational thinking,and according to the mapping relationship between the two,construct the project-based teaching mode of high school for computational thinking.Under the guidance of Ralph Taylor,grannd,stafelbim,Gardner and Bloom’s educational evaluation theory,combined with the analysis of classroom teaching evaluation suggestions and Computational Thinking evaluation mode under the new curriculum standard,this paper refines the evaluation strategies of Computational Thinking oriented high school project-based teaching mode,and finally designs a project-based teaching case based on this mode.By using the methods of investigation and questionnaire,240 senior high school students in a city high school in Hunan Province were selected to carry out a one semester teaching practice of information technology in the autumn of 2020,with a total of 19 class hours.The application of project-based teaching and students’computational thinking ability were investigated before and after the implementation of teaching,It is proved that the effective implementation of the project teaching mode can improve the students’ satisfaction and participation in the classroom to a certain extent,and the detailed classroom evaluation strategy can effectively evaluate the students’ project learning achievements and improve the students’ computational thinking level to a certain extent,This paper puts forward some suggestions for the implementation of project-based teaching of high school information technology for the cultivation of computational thinking.
