Study On Visual Teaching To Improve Mathematical Performance Of Secondary Vocational School Students

With the development of the times,information technology has also begun to be integrated into the research of mathematics education.At this time,there are many dynamic mathematics education software.The software integrates multiple representations of mathematical objects and promotes the study of multivariate representation in mathematical learning.These softwares integrate multiple representations of mathematical objects and promote the study of multiple representations in mathematics learning.Use a word,language,symbol,picture,concrete object,activity,or actual situation to represent a mathematical object,diversify mathematical representations,stimulate student interest and motivation,and transform and translate in various representations,from the initial shallow code to the construction of the deep code,and generate the payload.Mathematical visualization belongs to the category of external representation of Mathematics,and the corresponding visualization technology mainly refers to the use of graphics,images,animations and other "representative,dynamic,and clear presentation" representation of an abstract The mathematics object expresses,let people have an image,the intuition,the overall understanding and the comprehension to the mathematics study object.This paper puts forward a visual teaching strategy to improve the students' mathematics achievement of secondary vocational school,and tests it through teaching experiments.This research is mainly carried out from two aspects: theoretical research and practical research.In terms of theory,based on the visual representation of mathematics,the method of theoretical speculation is used as the main line,and the lessons learned and case analysis methods are supplemented.A visual teaching strategy to improve students' mathematics achievement in Secondary Vocational School is proposed.As follows:(1)Taking the actual life situation as the guide,create the mathematics visual multiple representation situation,combine "the graph,the formula,the table" to represent the core knowledge point of the teaching.(2)The stage of knowledge understanding and consolidation,the transformation and translation of multiple representations of mathematics visualization,the application of information packaging principles,and the dual channel principle in instructional design.(3)In the link of the integration of knowledge points,the principle of space proximity,time proximity and consistency are applied.In practical research,teaching experiment is taken as the main,supplemented by investigation and research,and mathematical teaching is applied to the teaching of mathematical visualization to conduct experimental teaching.The effect of the teaching experimental model on students' mathematics learning results and learning process is examined.The research results show that the teaching of mathematical visual representation has obviously improved the mathematics achievement of the experimental class.The survey shows that the experimental class students' mathematics understanding,problem solving,emotional attitudes,learning methods,and thinking levels have been positively affected.
