Research On The Project Learning Practice Of Junior High School Information Technology Subject Oriented To The Cultivation Of Computational Thinking

At present,the global scientific and technological revolution is in the ascendant,and scientific and technological innovation is accelerating,and deep integration,broad penetration into all fields of society.In the field of education,with the continuous transformation of the subject of information technology,discipline teachers are also paying more and more attention to the cultivation of students' information literacy and discipline core literacy in the process of teaching.Under the background of this big society,how to cultivate students' computational thinking has become a topic of increasing concern in the education circle.With highly informationization and the advent of the digital age,the core skills in the 21 st century,the students Computational Thinking with Critical Thinking and Problem solving ability,Creativity and innovation ability,communication ability,cooperation ability,should be each person should have the basic ability.In every subject,there is a large test bank,only relying on mechanical memory is difficult to improve,should pay attention to the cultivation of discipline thinking,and cultivate the sharpness of thinking,make it lifelong benefit.In the subject of information technology,students generally learn well in practical operation skills,but they are lacking in advanced thinking in the core quality of the subject.Professor zhou yizhen of Carnegie Mellon university in the United States defines computational thinking as "a way of thinking that USES the basic concepts of computer science to solve problems,design systems,and understand human behavior and a series of other activities." In short,computational thinking is the solution,and the highest level of learning is practice.A large number of domestic and foreign education graduate student has to calculate the thought the concept and characteristics of the sense of theory research,based on the exploration and calculation thinking,on the basis of relevant research,with project learning teaching model in junior middle school information technology course teaching classroom practice explores the cultivation of students' computing thinking,test the teaching effect,and sums up the calculation in the junior middle school information technology teaching thinking to develop the effective implementation of the strategy,provide feasibility for information technology teaching practice reference.This paper is divided into six parts.The first part describes the background of the topic,explains the purpose and significance of the research in detail,and analyzes the characteristics of computing thinking and project learning that junior middle school students should have.The second part systematically analyzes researchers' understanding of computational thinking at home and abroad and the influence of computational thinking on information recall courses at home and abroad,and sorts out the basic theories of integrating computational thinking into project learning.The third part is the core part of this study,to clarify the computational thinking in the Shanghai junior middle school information technology,and the project learning and "teacher","students","skills","thinking" and "attitude" series,the four core elements of fusion computational thinking "decomposition,pattern recognition,abstract and algorithm in which,a full range of design projects that cultivate computational thinking learning teaching model and strategies,and carries on the detailed description.The fourth part and fifth part based on the above situation,in the case of "view" practice teaching mode,and to validate its effect,based on the best Bebras and CTt before and after the test,in the process of teaching based on the former design flow chart and the past experience and the effect of solution directly to the student thought,analyzing the change of the students' thinking and comprehensive digital works,in order to explain the effectiveness of the project learning cultivate computing thinking.The sixth part makes a two-sided analysis and summary of the article,shows the conclusion of the study,and finds out the shortcomings of the study,so as to make improvements in the future work.
