Research On The Teaching And Learning Of Trigonometric Function In High School Mathematics

With the development of the new curriculum reform,teaching materials,teachers' teaching methods and students' learning methods are constantly changed.And one of the important contents in the knowledge of the trigonometric function as the high school mathematics,is the new curriculum reform occurred one of the larger changes in the content.Therefore,new curriculum reform content of trigonometric function teaching and learning research has gradually become the important task in current education research.In this paper,combining with the perceive of the teachers and the problems occurred in the actual teaching process,we proposed the research problem of this paper that is the teaching and learning research of trigonometric function in high school mathematics,on the background of the attitude of students as learning trigonometric function and the difficulties they encountened.The methods we used in the paper include literature analysis,questionnaire,individual interviews and so on.We inploer the knowledge of mathematics teachers about the new curriculum reform,by questionnaire investigation of the 34 in-service mathematics teachers on basis of the relevant theory and teaching practices.In order to further understand the view of teachers about trigonometric function,the author interviews the several mathematics teachers and lists the following questions:1.What do you think about the how curriculum reform influence on teaching of trigonometric ? 2.What do you think about the existence and the reason of difficulties exist when the students study the knowledge ?(you can talk about the view from learning method and learning content).3.How dou you deal with trigonometric function content under the effect of the new curriculum reform ? 4.What do you think about the problems in teaching of trigonometric function which under the arrangement in the teaching material ? Through questionnaire and test of 186 high school students questionnaire.It was found that the students' learning attitudes and habits.We could find the students' difficulties in specific sections through analysising the consequence of the questionnaires.Finally,the author combined with the results of the survey of teachers and students,then put forward the reasonable suggestions for teachers' teaching.1.Pay attention to the cultivation of students' non intellectual factors in the teaching process and strengthen the thinking training.2.Teachers should pay attention to the connection of the knowledge of trigonometric function in the primary and middle schools.3.The contents of the history of the trigonometric functions should be added in the teaching.4.The duggestions of the specific content of the trigonometric function teaching mainly include: strengthen the students to understand the concept essence of trigonometric function.Pay attention to the process of knowledge formated.The teaching of formula should focus on students' memory and application,in the image teaching of trigonometric function should pay attention to process and strengthen the application of trigonometric function model and focus on the application of multimedia.
