Practical Exploration Of Using GeoGebra To Cultivate The Core Literacy Of Middle School Students In Mathematics

The cultivation of students’ mathematics core literacy is the goal and the direction in the reform of our country’s mathematics curriculum.But most of the existing researches of mathematics core literacy are limited to theoretical analysis.Although there are a few teaching practical explorations of elevating students’ mathematics core literacy,because of the limitation of teaching methods causes not to achieve good results.To promote the cultivation of middle school students’ mathematics core literacy,the thesis designs teaching cases based on making full use of the advantages of GeoGebra.First of all,the thesis systematically researches the connotation of mathematics core literacy,the related educational psychology and the advantages of GeoGebra in mathematics teaching of middle school.The research background,content and meaning of this thesis are determined in view of these.Secondly through the questionnaire survey,I understand the current situation that middle school mathematics teachers use GeoGebra to cultivate students’ mathematics core literacy.So this thesis starts from five aspects to design teaching cases,such as in order to develop students’ mathematical abstraction and visual imagination literacy,this article uses GeoGebra to turn abstract content to concrete.In addition,using GeoGebra to turn static content into dynamic to cultivate students’ logical reasoning and visual imagination literacy.It as well as uses GeoGebra to achieve symbolic-graphic combination to develop students’ mathematical modeling,visual imagination and logical reasoning literacy.And this thesis uses GeoGebra to turn passive learning into active learning to improve students’ visual imagination and logical reasoning literacy.It also uses GeoGebra to turn boring content to interesting,for this to cultivate students’ data analysis and mathematical abstraction literacy.These cases include contents such as the concepts of oval and dihedral angle,the image and the nature of quadratic function,the dynamic math problems,the image of complex function,the exploration of three-view and expansion drawing,the simulated experiments of rotating body and random coin test.Then the data of questionnaire survey confirms the effectiveness of the designed cases in cultivating middle school students’ mathematics core literacy.Finally,the summary and the further research direction of this thesis are given.
