Practical Research On Improving The Teaching Effect Of Secondary Vocational Mathematics Classroom Based On GeoGebra Visualized Teaching

In recent years,the importance of secondary vocational education is more and more become the consensus of the social from all walks of life,in the national education reform and development compendium of 2010 proposed "to speed up the vocational education informatization construction,support high-quality skilled personnel training" the guiding ideology,thus in the context of informatization of education,the application of information technology tools for teachers in the classroom have a higher request,in the teaching process,teaching methods and teaching results have higher requirements.GeoGebra is the comparison of the current application of a wide range of information technology teaching tools,it sets the geometry,algebra,tables,graphics,statistics and calculus,and so on tool module,its strong interactivity,interface simple,material for free,easy operation,suitable for mathematics classroom teaching,visual experience for students mathematics,mathematics provides a very good environment to support.In this paper,the second chapter through analyzing the research status about GeoGebra mathematics education at home and abroad,the characteristics of the interface and function of GeoGebra compared,and the geometry sketchpad is introduced in detail,the advantages of cognitive development theory and constructivism theory,theory of multiple representation,fit the tower of experience,on the basis of theory,experiment courseware design visualization of mathematics.The third chapter introduces in detail the basic theory of GeoGebra visual instructional design based on the background of secondary vocational mathematics classroom,including instructional design principles,instructional design implementation principles,and instructional design specific instructional strategies.Using GeoGebra teaching software with conic unit as an example to design the teaching experiment and research,in the early stage of the experiment,through the use of interviews and questionnaires to the university mathematics teachers in conic difficulties appeared in the process of teaching and view of use GeoGebra teaching in-depth understanding,the students learning style to be measured using questionnaire test,for the teaching design and teaching of the experimental study of lay the foundation.In the middle stage of the experiment,I will screen out two classes with no significant difference.One class will be selected as the experimental class,and the GeoGebra software will be used for teaching,while the other class will be used as the control class,and the traditional teaching method will be used for teaching the same content.In chapter 5,the author gives detailed teaching case analysis and exercise case analysis based on GeoGebra taking conic curve as an example.Late in the experiment,starting from different dimensions,through the comparison and test scores before and after the students' classroom performance,three aspects of the questionnaire survey,qualitative and quantitative analysis,the results show that using GeoGebra visual teaching can be a positive influence on secondary vocational students mathematics study,to teachers' information technology teaching has certain reference value and significance.
