The Causes And Countermeasures Research Of Senior High School Students' Learning Difficulties Of Trigonometric Function

Trigonometric function is a kind of important basic function,it is also one of the main contents in high school mathematics.But senior high school students have many difficulties in learning trigonometric function.In order to understand the real situation of senior high school students learning trigonometry function and improve the quality of teaching,this paper takes three science class and two arts class students and teachers of the Affiliated High School of Luoyang Institute of Science and Technology grade three classes as the object,conducting investigation and study through a questionnaire survey and interviews on the high school of trigonometric function teaching and learning.Through the study,trigonometric function of senior high school students learning difficulties are mainly in the following aspects:(1)in the psychology,lacking of motivation and Negative attributions to learn trigonometric function.(2)in the knowledge and ability,basic knowledge of trigonometric function are not completely grasped,formula can not be applied flexibly,the ability of number shape union and computational is bad.(3)in the methods,using mechanical method to solve trigonometric functions problem,lacking of summary and reflection on the knowledge content.(4)in the teachers,not enough understanding of the importance of students participate in classroom activities,teaching concepts behind,lacking of emotional communication between teachers and students.Investigate its reason,have a lack of students' learning motivation,learning methods in inappropriate reasons,are also associated with teachers' teaching methods backward.According to the investigation and study results,this paper puts forward the following teaching strategies for trigonometric function study:(1)in the no cognitive aspects,teachers need to clear the students learning objective,learning motivation,exercise willpower.(2)in the cognitive aspects,emphasizes the understanding and using of trigonometric function concept and formula,emphasizes the number shape union thinking penetration and for computing ability and logical reasoning ability,emphasizes the importance of the summary to the study of trigonometric function,suggesting that the teacher a modest increase in class,increasing the trigonometric function exercises.for teachers,teachers should change the teaching idea,enhance communication between teachers and students.(3)in the students' learning strategies,the students themselves should preview the content and establish the wrong topic sets,forming the consciousness of reflection.
