Research On Scratch Learning Task Design In Primary School Oriented To Computational Concept Of Computational Thinking

With the accelerated development of information technology and the new demand for talents in the 21 st century,computational thinking has been attached great importance by the educational circles and has become one of the four core qualities of information technology disciplines in senior high schools.How to put the cultivation of computational thinking into practice has become a key issue for educators.This research makes a literal review about the topics and analyses the research status of Computational Thinking and Scratch at home and abroad and finds the appropriate point of this study on the basis of previous studies.Based on the constructivism theory,the theory of the zone of recent development,the theory of "learning by doing" and task-driven teaching method,this research constructs the basic link of Scratch's learning task design with the characteristics of primary school learners and the elements of general tasks.Taking computational concepts of Computational Thinking as the teaching objective,combining the task-driven teaching method and characteristics of Scratch,Scratch learning task design for computational concepts of computational thinking was carried out,and teaching practice was carried out in the fourth grade of a primary school.The questionnaire survey and the analysis of classroom task completion table are used to test the Scratch learning task design and teaching practice effect.The research results show that the Scratch learning task design and teaching practice oriented to computational concepts of Computational Thinking enable students to understand and master computational concepts,Students become more and more proficient in the application of computational concepts in the process of completing tasks.Gradually,students' abilities of analyzing and solving problems and hands-on operation are improved,and students' interest of information technology courses and Scratch courses are improved,and is conducive to the development of students' computational thinking.
