Research On Teaching Practice Of Scratch Programming Based On PBL

With the popularization of digital technology and open source hardware,the teaching of information technology in primary school has changed a lot.Professor from common tools software gradually turned to pay attention to cultivate creative thinking and movement and Scratch program design is the typical representative of the movement,as part of the information technology teaching,Scratch programming can not only improve students'practical ability,also helps to develop students' innovative ability.At present,the information technology teaching material in elementary school in Qingdao,with a time span of the semester to Scratch programming teaching,but because there is no form for this course teaching mode,most teachers still use traditional teaching model of information technology to teach this course,make the Scratch programming didn't get the effective play to the role of cultivating students' innovative ability,students learned only Scratch the use of programming software.Therefore,I,on the basis of former research about emerging teaching mode combining Scratch program design course and the characteristics of primary school students,trying to find out the suitable for Scratch programming teaching model,based on project learning elementary school Scratch programming teaching mode,in order to realize the value of this course.According to the research purpose and research content,on the specific research method of this research mainly adopts literature research,case analysis,action research method,experimental method and questionnaire investigation,research work on the following four aspects.(1)Theoretical research on project based learning(PBL)mode and Scratch programming teaching.Are reviewed at home and abroad about PBL teaching mode and Scratch programming on the basis of related research,project-based learning(PBL)model Scratch programming teaching in elementary school involved in the application of the related concepts and theoretical basis of system,the construction of teaching model to provide theoretical support for behind.(2)Construction of Scratch programming teaching mode based on PBL mode.The author combined with the project learning and teaching design related theory and elementary student's psychological characteristic,to project-based learning(PBL)model as the basis,the primary Scratch programming based on the pattern of PBL teaching design principles and components is introduced in detail,so as to build a primary Scratch programming based on the pattern of PBL teaching mode.(3)Carry out the teaching practice of Scratch programming based on PBL mode.A two-month teaching practice was conducted for fifth graders.Before and after the teaching experiment,the students were asked to fill in the questionnaire for the innovation ability assessment,and analyze the changes of students' innovation ability according to the data collected before and after the test.The author also conducted interviews with teachers who participated in the course in tiantai city school,and further verified the feasibility of the PBL model in elementary school Scratch programming teaching mode.With the gradual development of the above research work,the following notable achievements have been achieved in this study:(1)This study builds a PBL model of primary school Scratch programming teaching mode.Theory on the basis of constructivism,pragmatism and discovery,from the teaching goal,teaching object analysis,value analysis of Scratch program design course,and the analysis of the characteristics of PBL pattern,the project-based learning(PBL)model into Scratch programming teaching,build the Scratch programming teaching mode based on PBL pattern of primary school.(2)Verify the feasibility of the basic Scratch programming teaching model based on PBL mode.Teaching design is carried out according to the teaching mode constructed,and the teaching practice is carried out in tiantai city school in chengyang district,Qingdao city.Through the analysis of the questionnaire and the interview results,draw the conclusion:elementary school based on the pattern of PBL teaching mode applied in Scratch Scratch programming is effective in programming teaching,the teaching model can largely stimulate students interest in the course,at the same time promote students' innovative ability and team cooperation ability and so on also has a good effect.Due to a wide range of application is not present in the teaching mode to the daily teaching of information technology disciplines,there are some uncertain factors,such as how to choose a more suitable project,how to set up project based learning(PBL)model for the environment,the role of teachers can be a good helper,and so on.In the future teaching practice and research,will continue to revise and improve.
