Research On The Design And Application Of Geogebra-supported Teaching Scaffolding

With the progress of society and the development of information technology,in order to train all-round development of successors to meet the needs of the development of students’ core literacy,we must carry out classroom teaching reform!Mathematics is a subject with both knowledge and skills.The improvement of mathematics literacy is of great significance to the all-round development of students.As an important part of high school mathematics,analytical geometry is a comprehensive reflection of mathematical literacy,learning this part is of great significance to the promotion of mathematical literacy.But at present,the teaching of analytic geometry is mainly about information technology assisting teachers to give lectures,stressing the leading position of teachers and neglecting that students are the main body of learning.Based on the theory of the zone of proximal development and the theory of scaffolding,this study designed the scaffolding with the support of Geo Gebra to support students’ learning and improve their ability of analyzing and solving problems.This study adopts various methods such as investigation,action research,and quasi-experimental research.First of all,it is clear that the main problems existing in current teaching are: students’ weak ability to analyze problems through combination of numbers and shapes,and they cannot flexibly transfer and apply them;Secondly,it is necessary to further improve and expand the existing problem scaffolding,task scaffolding,resource scaffolding,and peer scaffolding.The problem scaffolding is further refined into a problem sorting scaffolding,incorporating the key link of using Geo Gebra to map and clarify the relationship between known and requirements;The task based scaffolding is further refined into three problem guidance maps and problem variation exercises,which are integrated into the key link of building a model to clarify the direction of problem solving;The use of Geo Gebra modeling experiments is also incorporated into the peer stent,making it clearer for students to communicate,discuss,and demonstrate with support from Geo Gebra.Thirdly,integrate various types of expanded and improved scaffoldings into each link of teaching,construct a teaching scaffolding supported by Geo Gebra,provide support for students in solving comprehensive problems in analytical geometry in various links such as problem review,thought guidance,experimental exploration,communication and display,and variant training,and further optimize the stereotyped teaching scaffolding through three rounds of action research;Finally,a quasi experimental study was used to test the application effect of the teaching stent.By analyzing the data measured before and after the experiment class and the control class,the data measured before and after the experiment class,the data measured before and after the experiment class of the students at different levels of mathematics performance,and the experimental data of the mathematics learning self-efficacy of the experiment class before and after the experiment,it is found that:The Geogebra-supported teaching support can improve students’ math performance and show significant improvement compared to high level students,intermediate level students and low level students;There was also a significant difference in students’ self-efficacy in mathematics learning before and after the experiment.The teaching support supported by Geo Gebra could improve students’ self-efficacy in mathematics learning.With the support of Geo Gebra,we explore the design and application of teaching support,providing a new direction for the application of Geo Gebra in teaching,improving the traditional teaching method of analytic geometry,returning the classroom to students,improving the teaching efficiency of teachers and students,so as to truly realize the teaching of students according to their talents,reducing the burden and increasing the efficiency.
