Study On Trigonometric Function Teaching Of Facing Vocational Technical Secondary School Students

Secondary vocational education is an important part of modern education,and is an important pillar of industrialization,socialization and modernization of production. Engineering secondary vocational schools is to train the engineering professionals.The study of the major curriculum in engineering needs the massive mathematics knowledge as a basic. Mathematics is not only a tool for learning expertise,but also for the cultivation of rational thinking.It plays an irreplaceable role in analytical ability and innovative awareness of the training.Trigonometric as a basic knowledge in mathematics reveals the triangle in the segment and the angle precise quantitative relation.So it is extensively used in surveying, engineering,mine surveying work.It plays an important role in the engineering category expertise.This paper is divided into five parts.Partâ… puts forward the problem.Due to the poor basic of mathematics and lack of interest in mathematics in the secondary vocational schools, coupled with the contradictions between existing curriculum and class,mutual independence between mathematics and specialized classes,teaching methods,the learning situation of trigonometric function is not optimistic.Because trigonometric function is the basis of most specialized classes in secondary vocational school of engineering courses,it's very necessary to study trigonometric function there.Partâ…¡is the literature review.Trigonometric function of secondary vocational schools knowledge framework,and trigonometric functions of the existing teaching requirements of the brief,And the current newspapers,magazines,research and analysis can be seen on vocational education in mathematics research mostly on comprehensive research,teaching and research of the trigonometric function of it is very little. Therefore,it's necessary to do a research for trigonometric function.Partâ…¢is mainly talked about the theoretical foundation of teaching trigonometric function,and through the cognitive and development theory,constructing learning concept,teaching theory of Zan Kefu,the theory of emotional psychology,and other analyses,this study provides a theoretical basis. Partâ…£is conclusion.On the basis of experiment,we draw a number of suggestions. Teachers should be in a high sense of responsibility during the study process,and have a mathematical application of awareness in teaching in vocational schools.In lectures to be as far as possible,trigonometric function in the abstract knowledge of specific,modular teaching try to make the structure more clearly trigonometric functions,In trigonometric function,the necessary adjustments trigonometric function of the teaching,students have easy migration, the trigonometric function with the knowledge through learning,As the basic course in the deletion of the large number of vocational schools,students stay more after-school work is an extension of classroom teaching,for better impression of students,improve performance, Teachers in class as much as possible the use of modern educational technology,computer multimedia applications will trigonometric function images of specific knowledge,for students to understand;The assessment mechanism for the students must be adjusted.Not only evaluating using papers,but also using a variety of evaluation system,so that students have better development space.Partâ…¤is experiment.Through the teaching test of two selecting parallel classes for a semester in Shijiazhuang Technology and Engineering School, comparing the end results it can be seen the achievements of the experimental class is much higher than the comparative class achievements.
