Design And Implementation Of Learning Activities Of Information Technology Extended Course In Middle School Oriented On Computational Thinking

In 2017 promulgated "ordinary high school information technology curriculum standards" clearly put forward that the cultivation of the ordinary high school information technology course goal is to make students further enhance the overall quality,focus on the development of core accomplishment,has the ideal faith and the social sense of responsibility,has the scientific literacy and lifelong learning ability,has the independent development ability and communication ability to cooperate.Curriculum standards stress that high school information technology courses should always focus on the core quality of the subject,which includes information literacy,computational thinking,digital learning and innovation,and information social responsibility.As a key component of the core accomplishment,computational thinking has laid a good foundation for students to adapt to The Times,the society and their lifelong development.Although the general high school curriculum standard clearly states the importance of the cultivation of computational thinking,the cultivation of computational thinking is a long-term process,which should be involved in the k-12 stage.At present,in k-12 stage,there are more researches on information technology courses related to the cultivation of computational thinking in primary school,while relatively few in junior high school.In this context,this study,based on relevant literature,combined with the characteristics of junior high school students and teaching content,proposed a learning activity design model for the cultivation of junior high school computational thinking by optimizing teaching methods,and carried out educational practice in a middle school in S city to explore the influence of this model on the learning effect and computational thinking of students.The paper including the following aspects:This paper presents a learning activity design model of information technology development course in junior high school,which is oriented by computational thinking and problem driven teaching.Combed the research at home and abroad about the concept of computational thinking,connotation,development and education theory and practice,problems and challenges,such as literature,and further research on the problem solving model,cognitive learning theory and teaching system design and related education theory: on the basis of problem solving schema theory,puts forward the problem-solving process for computing thinking training characteristics.Based on the theory of cognitive-discovery learning,this paper expounds the characteristics of teacher-student-theme teaching model.Based on the systematic instructional design,the model elements of the learning activity design model of the junior high school information technology extension course for the cultivation of computational thinking are obtained.Finally,based on the information technology curriculum standards of ordinary senior high schools,by referring to the teaching models based on computational thinking at home and abroad,and combining with the characteristics of students,a learning activity design model of junior high school information technology extension course oriented to computational thinking is constructed.A series of learning cases are designed based on the learning activity design model of junior high school information technology extension course oriented to the cultivation of computational thinking.Based on the theory of computational thinking,this study selected the learning activity design under the new model of information technology extension course in junior high school.Based on the learning activity model,a series of learning cases of information technology extension course in junior high school are designed.Carry out case practice of information technology development course for the cultivation of computational thinking,and explore the effect of case implementation and students' learning feedback.This study carried out a one-year teaching practice in a middle school in S city.By collecting,processing and analyzing the experimental data of experimental classes and control classes,this study explored the influence of the learning activities of information technology extension course in middle school oriented to the cultivation of computational thinking on students' computational thinking,academic performance and learning motivation.Through the analysis of the learning effect,this study finds that the implementation of the learning activities of junior high school information technology extension course oriented to the cultivation of computational thinking can: A.it can improve students' computational thinking ability to a certain extent.B.it can promote students' interest in class to some extent.C.it can improve students' academic performance to some extent.
