Design And Implementation Of Scratch Teaching Oriented Towards The Cultivation Of Primary And Middle School Students' Computational Thinking Ability

The development of social economy and information technology is rapid,the emergence of Internet banking marks the "Internet+ Finance"has entered a new stage,and it also reflects that information technology covers all aspects of people's work and life.Whether information technology can be used to solve practical problems today has become an important criterion for measuring talent,and computational thinking has become an indispensable ability for citizens.However,at present,the cultivation of computational thinking in China is mainly concentrated in courses such as computer foundation and program design foundation in universities.The cultivation of computational thinking in primary and secondary schools is slightly insufficient,and there is also a lack of corresponding curriculum resources to cultivate computational thinking in primary and secondary schools.The improvement of primary and secondary school students'computational thinking can help them better understand and study engineering courses.This not only lays a solid theoretical foundation for computer-related courses in junior and senior high schools,but also learns office software or computer programming languages on the road to career development.No small help.Scratch software teaching is an effective way to train students' computational thinking.It integrates computational thinking into fun and entertaining game programming,so that elementary and middle school students can learn the basics of programming in fun games,and at the same time exercise their rigorous and rational logical thinking skills.Lay a good foundation for future learning.Based on the specific calculation stage in Piaget's cognitive development theory,the theory believes that children at this stage have a certain logical understanding of symbols,graphics,etc.Therefore,the Scratch programming mode is not only suitable for students to learn,Also able to develop their intelligence.In addition,because Scratch software is a graphical interface software,students do not need to learn and memorize difficult sentences and grammar,nor do they need to spend a lot of time to modify the code,directly participate in design and creation,and can complete a short works.For elementary and middle school students,they can not only learn computational thinking,but also cultivate students' interest in software development.Therefore,scratch programming software has been greatly recognized by teachers and students in elementary and middle schools,and has been widely disseminated worldwide..In order to solve the problem that China still lacks in the cultivation of computational thinking of primary and middle school students and the shortage of related curriculum resources,this article has designed a curriculum suitable for the cultivation of computational thinking ability for our primary and middle school students from various aspects.First of all,this article consulted the relevant literature on computational thinking theory at home and abroad,and then studied the theoretical and practical significance of using the programming software of scratch programming to cultivate the theoretical and practical significance of computational thinking for primary and secondary school students.Carry out teaching practice activities to improve computational thinking.The interview method,questionnaire method,literature research method and educational experiment method are used to test the computational thinking of primary and middle school students,and then the pre-test and the classroom test after the course are compared and analyzed.The statistical results show that the teaching design of the computational thinking course developed on the basis of scratch programming software adopted in this paper has improved the computational thinking ability of elementary and middle school students,and according to the questionnaire,some students also apply it to solve daily life problems.It shows that the scratch teaching design and implementation oriented to the development of computational thinking ability of primary and middle school students is practical,and based on the influence of multiple factors,the teaching design plan is still sufficient.
