Action Research Of Clever Mathematics In Elementary School Mathematics Teaching

First of all,the new curriculum has repeatedly mentioned that we should pay attention to the cultivation of students' inductive reasoning ability,and pay attention to the application of mathematical thinking methods in teaching activities.Secondly,in dealing with the relationship between algorithm diversification and algorithm optimization,it is pointed out that different ideas of students' cognition should be respected,and students should be encouraged to think independently.For the algorithm put forward by students,it is necessary to guide them to carry out comparative analysis on various methods in time,and select the most universal,concise,conducive to subsequent learning and suitable for their own optimal methods.In the process of analysis and comparison,let students gradually learn the mathematical thinking method of "choosing the best from the many,and choosing the simple from the best".The significance of skillful calculation lies in the process of observation,analysis and comparison,and the cultivation of students' thinking.Therefore,this study puts forward the topic of "action research on ingenious calculation in mathematics teaching of the fourth grade of primary school".This study mainly uses the methods of test,interview and action research.In this paper,the action research is divided into two rounds.Before the first round of action research,the author summarizes the methods and skills of smart computing.It can be divided into four types: skillful calculation by changing the order of operation,skillful calculation by changing the type of operation,skillful calculation by using complements and integers,skillful calculation by using formulas and rules.Secondly,the author analyzes the mathematics teaching materials of grade three and grade four of Beijing Normal University Edition,sums up the embodiment of clever calculation in the teaching materials,and analyzes the feasibility of clever calculation in primary school mathematics teaching.Then the author investigates the teachers' understanding and implementation of smart computing through interviews with teachers,and then investigates the current situation of smart computing of fourth grade students in primary schools through test questions,and analyzes the variance of students' test scores under different factors,finds out the existing problems,and analyzes the existing problems.Thirdly,according to the current situation of targeted action research,taking class a primary school in s city as the object of action research.The process of action research mainly includes planning,implementation,discussion andexisting problems.After the first round of action,through the after-school interviews with students,discussions between teachers and the author's personal reflection,the existing problems are adjusted and modified,and the second round of action research is carried out.After the action research,through interviewing the teachers and testing the students,the author analyzes the changes of the students after the learning of the ingenious calculation,and concludes that the teaching of the ingenious calculation is helpful for the students to master some thinking methods,improve the students' logical thinking ability and inductive reasoning ability,help the students to master some ingenious calculation skills,so as to improve the accuracy of the calculation,and help the students to improve the accuracy of the calculation Conclusion of interest in learning.Finally,according to the teaching practice and group discussion,some suggestions on how to carry out the teaching of smart computing are put forward.Hope to be able to provide a reference value for the teaching of front-line teachers.
