Three-dimensional Geometry Teaching Research In Vocational High School

Three-dimensional geometry is the important composition of thevocational high school mathematics course,the status and effect of it is notallow to ignore and irreplaceable.But all sorts of factors lead to a lot ofdifficulties in vocational senior high school three-dimensional geometryteaching,it makes the teaching goal difficult to reach, and this chapter directlyaffect students’ maths learning effect.So to improve teachers’ teachingideas,seek for the efficient way of teaching in recent years has become anurgent problem.This subject combines with the actual and finds ways to improve thethree-dimensional geometric quality of teaching in vocational high schools.This thesis is composed of the following five chapters:First,preface expounds the purpose and significance of research, andintroduces the research current situation, research methods and innovation.Second,analysis of the status of three-dimensional geometry teachingof vocational high schools,on the basis of surveys and interviews,itsummarizes vocational high school mathematics teachers’ current situationand attitude of the students of solid geometry.Third,briefly introduce the three-dimensional geometric features andsignificance and function that students learn this chapter,emphasize its importance.Fourth,according to the actual situation of vocational high school,elaborate on the three-dimensional geometry teaching strategies example.Firstof all, mathematics teachers need to change the teaching philosophy.Second,optimize the teaching methods to enhance students’ interest inlearning. Then, propose the strategy from the beginning of high schoolknowledge of convergence, featured content, layered teaching aspects.Fifth, teaching reflection,three-dimensional geometry teaching ofthe vocational high schools restricted in many ways,therefore,requires thejoint efforts of all levels of education departments and social and each personto change the unfavorable situation.
