Teaching Research Based On Scratch Elementary School Students' Computational Thinking Training

This topic will Scratch programming education into primary school information technology in the classroom,the first office in combination with the current school teaching the students’ learning and information technology environment,design scientific and reasonable computing thinking cultivation of teaching practice,and then through class observation and quantitative appraisal,the calculation of the way to evaluate students questionnaire and thinking ability from what aspects.In this way,the traditional information technology classroom is based on software teaching and technology teaching,and does not pay attention to the dilemma of cultivating students’thinking ability.Scratch the course’s content is no longer a boring talk programming algorithm,but the knowledge to infiltrate life example,driven by one of the fresh subject knowledge learning,let students experience the complete development process,a program know computer program of the solution,so as to calculate the thinking for the development of students,for students in primary school information technology course teaching of computational thinking to provide reference and reference.First of all,this research topic was determined according to the author’s actual situation:teaching and research on the cultivation of students’ computational thinking based on Scratch.Then,according to the learning characteristics of primary school students,six core objectives for the cultivation of students’ computational thinking were determined,as well as the research ideas of this topic.In combination with the actual design,the teaching activity model of Scratch based courses was designed,and the teaching case analysis of specific course implementation process was given.Based on the analysis of the learning situation of the students in the primary school,the author designed visual teaching tools for different computational thinking stages:storyboard,script planning block diagram and flow chart of role scripts in Scratch,etc.With these teaching tools,students can have a clear understanding and grasp of the role,script and stage of each unit theme,which lays a foundation for the following program design.Then the author carries on the teaching activity practice combining the preliminary analysis and the design.It includes the analysis of research environment,research object and teaching design,the formulation of specific teaching steps,teaching practice and improvement strategies.Then according to the characteristics of computational thinking design teaching evaluation.Thinking test and calculated using the Bebras international Dr.Scratch application for student work analysis and so on the many kinds of evaluation methods to evaluate students thinking ability development calculation,it is concluded that the study of the course based on Scratch calculation for elementary school students thinking ability development has a role in promoting,and summarized problems and resolving problems of elementary school students ability and creative expression and collaboration capabilities has more obvious improvement,and abstract problem ability and design ability of the role is not obvious,needs long-term training.Finally,this paper summarizes and looks forward to the research,summarizes the innovation and shortcomings of this research,and puts forward prospects for future Scratch teaching research,expecting more educators to participate in the research work on the cultivation of computational thinking,and make contributions to the development of students’ computational thinking ability.
