Research On High School Matrix Teaching Design Based On Geogebra

Our country draws lessons from foreign experience and introduces the matrix into the mathematics textbooks in the high school.However,in the actual teaching process,the matrix teaching also faces some challenges,For example,teachers lack teaching cases and their teaching methods are simple;students learn difficult,unskilled operation,and poor understanding of the value of the matrix.In this context,the author believes that the use of modern educational technology to improve the teaching design of this part of the matrix should be a means to solve the current problems in teaching activities.To verify the feasibility of this idea,the author will combine high school mathematics textbooks and linear transformation related content,carry out teaching design research,and put the design into practice,draw conclusions according to the effect of practice.In the course of the implementation of this research,the author conducted research on teaching design based on the design of this part of the matrix of high school mathematics textbooks in Shanghai,combining the relevant knowledge in linear transformation and the functional characteristics of Geogebra software.A part of the matrix content teaching design applied to Geogebra software assisted is designed.After completing the design work,experimental classes were selected to conduct teaching experiments.Students’ observations on the teaching design and the role of Geogebra software in student’s learning were known through observation of the students and student interviews and questionnaire surveys conducted after the class.Through the experimental results obtained,the author found that it is feasible to apply the Geogebra software in the process of high school matrix teaching.In the teaching of the matrix,it is possible to introduce the contents of the linear transformation when explaining concepts and examples,and use Geogebra software to demonstrate,experiment,and explore.This approach helps students understand the matrix more comprehensively.In addition,using Geogebra software in class can effectively improve its learning efficiency and deepen its understanding of knowledge,especially in relation to geometric and geometric transformations,the use of Geogebra can give students a powerful effect.
