Based On The Teaching Materials Of High School Trigonometric Function Samples Research

Teaching of the sample with the examples of the teaching material for this,not only can consolidate the new knowledge can also improve the students' problem solving ability and quality of mathematical thinking.Math teacher a line at the moment,more emphasis on mathematical examples teaching,many teachers do not take the teaching materials of mathematical examples,think the examples in the teaching material too basis,students have very few,many teachers just topic topic,did not play the function of sample.Based on this,this paper mainly studies the questions:(1)What are the sample function mainly in the textbook today?(2)Taught A version of the required 4 \ "the first chapter of trigonometric function \" the corresponding sample contains what function?(3)A line of teachers are examples of how to use teaching material? Whether the function of the corresponding sample?To solve these problems,the author through the literature method,case method,experience method,research methods,such as trigonometric function examples in teaching to the teaching material is studied.Summary by querying the related information out of the first examples of function;Second,to teach A version must be 4 in the first chapter of the sample were analyzed,and the statistics of the function of various examples,the number of representative examples are emphatically analyzed;Then,through the teaching view and communicate with first-line teachers,understand they are examples of how to use teaching material,analysis whether they play the function of the sample;Some teaching advice is given.Through the study of the above content can be concluded that the current first-line teachers blindly pursue puzzles and focus of the university entrance exam,not attaches great importance to the teaching material of trigonometric function examples,not play the function of the sample.To this,the author with a line of teachers actively communicate and query literature,teaching materials in the sample suggestion is given.
