Effects Of The Use Of GeoGebra On The Learning Of Functional Image Transformations

The extensive application of information technology in mathematics teaching can present contents and effects that cannot be presented by traditional teaching methods,and it plays an important role in cultivating students’ scientific spirit and innovative consciousness and improving their core qualities of mathematics.As an open source software for dynamic geometry,which mainly presents mathematical contents,GeoGebra has been rapidly promoted and used in China in recent years.Through comparative experiments,this paper studies the influence of the use of GeoGebra on the learning of function image transformation.The main research questions are as follows:(1)How to take the GeoGebra software as the platform,strengthen the integration of information technology and mathematics courses,and design the teaching of trigonometric function graph transformation?(2)Is the trigonometric function image transformation teaching based on the GeoGebra software better than the teaching without the information technology support of the GeoGebra software?(3)Whether integration into the mathematics teaching of the GeoGebra software can improve the academic performance of students at different levels?In order to study the above problems,the literature analysis method was first used to consult,sort out and analyze the existing literature according to the needs and existing theories,so as to form a deep understanding of the research problems,determine the research ideas,design the teaching design integrating GeoGebra with the mathematics course,and modify and improve it in combination with the opinions of the instructors.Secondly,comparing experiment method to implement,three subjects class does not use GeoGebra respectively,teachers use,teachers and students to share,after examining whether the results have significant differences,then using SPSS 22.0 software to analysis the influence of gender on students’ academic performance,presence of GeoGebra influence on student achievement,GeoGebra on the influence of different level students grades.Finally,based on the post-test results,interviews were conducted with students at different levels in each group to understand the students’ attitudes towards the GeoGebra assisted instruction and analyze the impact of GeoGebra on students’ learning.Using SPSS 22.0 software to analyze the experiment data,the conclusion is drawn:(1)Although there are differences between male and female students in the average posttest scores,there is no significant difference.(2)Three results overall has significant difference after class,and the effects of the difference between the effect and great effect,the difference is mainly using class teachers and unused class’s and grade’s share class with teachers and students,teachers use class differences,differences in effect is in effect,and the lecturer used alone GeoGebra influence on student’s academic performance is superior to the teachers and students teaching common use GeoGebra school and do not use GeoGebra.(3)Compared with the unused classes,the two groups were divided into one group.There was a significant difference in the students’ post-test scores.The effect of difference was the median effect.(4)According to the students before the test scores high rankings are divided into groups,among group and the low group,after the high group students test scores have significant difference,the difference of effect to the effect,the difference is mainly using class teachers and unused classes,teachers taught separately using GeoGebra influence on student’s academic performance is better than not using GeoGebra teaching;There was no significant difference between the middle group and the lower group.Based on the research results and conclusions,the following teaching Suggestions are put forward:(1)Profound understanding of mathematical knowledge,overall grasp of the knowledge system;(2)Strengthen technical operation training and pay attention to the improvement of information literacy;(3)Based on classroom research,teachers and students cooperate to teach students in accordance of their aptitude;(4)Develop Shared teaching resources and extend learning both inside and outside the classroom.
