The Study Of Learning Disabilities And Teaching Strategies From Fresh Students Of Senior Middle School In Trigonometric Functions

The trigonometric function is one of the important elements of high school mathematics,and it is a kind of basic elementary functions which describes the periodic phenomenon.Besides,it runs through the whole middle school and university which plays a great role in the research series,conic curve,derivative and series.According to the contents of the new curriculum reform in high school,the curriculum is divided into two parts: compulsory and elective which needs to follow the way of the field,subject and module.The contents of the trigonometric function are distributed in the first and third chapters of compulsory 4 as well as the first chapter of compulsory 5.In these chapters,although the contents of the textbook are partially changed,the application of the positive and cosine theorem is enhanced in general,and the function of the function model is emphasized.In this study,the author takes the three parts---the trigonometric function,the trigonometric identity transformation and the triangular triangle as the starting point,selects the fresh students who are from one senior middle school of Nanchong in Sichuan Province as the survey objects,collects the data of the questionnaire and the individual interviews,and finally sorts out the useful information and reliable data.By sorting out and analyzing the results of the research,the author finds that students are in learning disabilities which are mainly affected by the two aspects: First,from the aspect of students,the learning disabilities are roughly divided into two aspects of intelligence and non-intelligence;Second,from the aspect of teachers,the learning disabilities are mainly from the teaching idea,teaching style,teaching method and etc.Finally,this paper will provide the corresponding opinions and Suggestions for teachers' teaching and students' learning which is based on the comprehensive analysis of the actual research data.
