Research On The Problems And Countermeasures Of The Development Of Mathematics Teaching Service In Secondary Vocational School

Mathematics is a basic course for talent training in secondary vocational schools and an important means to improve students' comprehensive quality.Mathematics teaching in secondary vocational schools must not only provide students with the necessary basic knowledge of mathematics in order to meet students' needs of learning and lifelong development,but it should also highlight the characteristics of serving the current teaching of professional courses.However,at present,mathematics teaching in secondary vocational schools is not closely connected with professional courses.In particular,some of the mathematical knowledge involved in professional courses has not been learned by students and some can not be applied by students,due to which,teachers of professional courses have to spend time supplementing the corresponding mathematical knowledge.In other words,as a basic course,mathematics does not achieve the aim of serving professional courses.Therefore,this research will start from the status quo of mathematics teaching serving students' professional development in secondary vocational schools,to find problems,figure out the causes,propose countermeasures and conduct teaching experiments.First,this paper uses literature analysis to sort out the research status of secondary vocational mathematics teaching and secondary vocational mathematics as professional service,in order to grasp the research status of the subject and lay the theoretical foundation.Second,using questionnaire survey and interview method to investigate and interview five students and teachers majoring in agricultural machinery and garden technology in A secondary vocational school,in order to master the basic situation of mathematics teaching in secondary vocational schools serving for professional development,it is found that the development of mathematics teaching service specialty in A secondary vocational school has some problems.Because of these problems,the basic understanding of mathematics teaching,the disjointed demand between mathematics and enterprises,the inappropriate teaching materials and teaching reform are not in place,and then the practical plan of teaching reform of mathematics teaching service specialty in A secondary vocational school is put forward.Third,it is also necessary to reform the course contents according to themathematics knowledge needed by each major,arrange the mathematics teaching contents of each major reasonably,adjust the mathematics teaching progress according to the professional teaching plan,and pay attention to the knowledge connection between specialty and mathematics;and reform the teaching and learning Learning methods and means;optimizing the professional evaluation system of mathematics in secondary vocational schools.Fourth,according to the reforming trend,combining the demand of the major of gardening for mathematical knowledge with the demand of the major of agricultural machinery for mathematical knowledge,this research designs in detail the teaching content,teaching methods,and teaching cases.For either major,two teaching cases are provided,in which practical problems are solved mainly through introducing professional situations,requiring students to measure by themselves,and teaching students to use geometry sketchpad,Excel as well as the idea of mathematical modeling.Finally,taking two classes of garden technology specialty as experimental class and control class,combining the data of pre-test and post-test of mathematics achievement and learning attitude,the effect of mathematics teaching reform in secondary vocational school is compared and analyzed.The innovation of this paper is as follows: To explore the teaching practice from the aspects of the structure arrangement of mathematics teaching materials,mathematics teaching design,teaching examples and so on.This article also carries on the experiment to the secondary vocational school mathematics teaching service specialized development practice,contrasts before and after the test data,has demonstrated the feasibility of the scheme.
