Investigation Of Trigonometric Functions Learning Status Of High School Students With Learning Difficulties

Trigonometric function is an important knowledge in senior high school.As there are many trigonometric function knowledge points and formulas,senior three students with mathematical learning difficulties will encounter many difficulties in the review.In order to understand the specific difficulties encountered by students with learning difficulties,analyze the reasons,and put forward targeted review strategies to help students master trigonometric knowledge and improve math scores,this paper has carried out an investigation and research on the learning status of trigonometric functions of senior three students with learning difficulties.By means of questionnaire survey,test paper survey,student interview,teacher interview and other methods,this paper investigated some senior three students with learning difficulties in an ordinary high school in the city of Ankang,Shaanxi Province with the purpose of understanding their mastery of trigonometric functions.Through investigation and analysis,it is found that the students with learning difficulties have the following four typical difficulties in trigonometric function learning: forgetting related concepts and formulas,making mistakes in the process of operation and reasoning,ignoring the summary of problem-solving methods and skills,lacking of interest and confidence in trigonometric function learning.Among them,the first difficulty is the most common one that most students with learning difficulties will encounter.According to the results of the investigation,this paper has put forward the review strategy for the management of wrong questions.By guiding the students with learning difficulties to manage the wrong questions effectively,the results of the monthly examination of the students who participated in the survey were improved to some extent.Finally,this paper has put forward some teaching and learning suggestions for students with learning difficulties.
