Research On The Teaching Reform Of Solid Geometry In The Mechanical And Electrical Major Of Secondary Vocational School

Solid geometry has a high degree of abstraction and complexity.As a mathematics teacher in secondary vocational school,how to combine this course with the professional background of each professional student to serve the professional basic courses and professional courses,improve the teaching effect of this course,and achieve the purpose of serving the students' professional learning is a problem worthy of in-depth study.Taking the mechanical and electrical major of secondary vocational school as an example,this paper studies the "personnel training program of mechanical and electrical major","Teaching Syllabus of mechanical drawing","teaching syllabus and teaching materials of mathematics" and other documents and materials from which to find the connection point and application point of the course of solid geometry According to the survey of the current situation of mathematics course teaching,the "mathematics course plan of secondary vocational school" is extracted through the interview of teachers;through the questionnaire of students,the opinions on the course of three-dimensional geometry are obtained;the teaching situation of three-dimensional geometry of mechanical and electrical major in secondary vocational school is obtained: the subject system and teaching content of mathematics course are overemphasized,resulting in the opening of three-dimensional geometry course Some problems such as semester lag,teaching content can't connect with professional courses,etc.In view of these problems,the author puts forward "the overall design of the course reform of solid geometry" for the mechanical and electrical specialty of secondary vocational school ".Based on the principle of the overall design of the course reform of solid geometry,which is the practical guidance of the professional posts and the "must and enough" knowledge of the mechanical and electrical specialty,and taking the contents of "geometric drawing","projection","view and three views" and "space rectangular coordinate system" in the course of solid geometry as the breakthrough point,the teaching contents of the reform oriented by the cultivation of professional core competence are put forward The teaching reform strategy of "moving forward the semester of solid geometry,adjusting the teaching content of solid geometry" and the classroom optimization strategy of "transforming the actual situation of the working process field into the situation of the learning field".Based on the practical work cases of vocational posts,the course "solid geometry" for the mechanical and electrical specialty of secondary vocational school was developed,and "three views of space geometry" was used as the teaching design cases(including teaching design and teaching design analysis).Through the comparative teaching experiment of two parallel classes of mechanical and electrical specialty,it is concluded that the reform of solid geometry is helpful to the study of mechanical and electrical specialty.
