Research On The Practice Of Science Micro-teaching Based On Cultivating Critical Thinking Of Fifth-grade Students

Students can't grow without critical thinking.In primary school,to cultivate students' critical is to improve their abilities in all aspects.The improvement of their ability can lay a solid foundation for them to become a person with ideas,foresight and not going with the flow in the future life.However,domestic textbooks are different from foreign textbooks in that there is no special module for practice,and the cultivation of this aspect is extremely urgent.Therefore,the intervention of micro class can't only improve students' abilities in all aspects,but also train students to think rationally,change the previous teaching mode,and stimulate students' interest in learning and exploration.To prepare for the cultivation of innovation talents.Based on the above and below nature textbooks of grade five in Shanghai education edition,this paper selects the content suitable for the micro classes,sorts out,arranges and classifies them,and produces micro classes to cultivate students' critical thinking.In this process,the strategies and methods of cultivating students' critical thinking are summarized,which also provide references for cultivating other excellent talents.This article mainly uses the questionnaire survey method,the literature method,the action research method and the experience summary method and so on.In the questionnaire survey,the Cornell critical thinking ability test(Cornell Critical Thinking scale grade X,Cornell Critical Thinking Tests,CCTT)for elementary school seniors and California Critical Thinking Disposition Inventory(CCTDI)was selected.The former has 71 questions,witch are based on the stories and test students' critical thinking ability.The latter tests students' critical thinking tendency from seven dimensions,truth seeking,open mind,analytical ability,systematic ability,self-confidence of critical thinking,thirst for knowledge,and cognitive maturity.This paper consists of four parts.The first part mainly analyzes the differences in the cultivation of critical thinking at home and abroad,so as to put forward thesignificance of the research on the cultivation of critical thinking oriented science micro-course teaching for fifth-grade students.The second part is the concept definition and theoretical support of science micro-course activities,and expounds the relationship between science micro-course teaching and the cultivation of critical thinking of fifth-grade students.The third part introduces the whole process of cultivating the fifth grade students' critical thinking oriented science micro-course teaching.The fourth part summarizes the conclusion of this teaching activity.Micro class can change the teaching mode,that is,change the way of thinking of students,from passive absorption of classroom knowledge to active thinking,active participation in classroom activities,and exploration of the mystery behind,which is conducive to the cultivation of students' critical thinking.Experiments have proved that once students' interest in learning and inquiry is stimulated,they can take the initiative to participate in classroom activities,and they can complete small tasks without the teacher's advice.Student in grade five of primary school are curious and fond of new things.The addition of micro classes makes up for the dullness of classes and makes a class rich and effective.In the process of participating in activities,students' abilities in various aspects are improved and their critical thinking is gradually cultivated.
