Application Of Geometer's Sketchpad In Geometry Teaching Of Junior High School

In junior mathematics,geometry plays an important role,and some knowledge in geometry is more abstract.The junior high school students' abstract thinking ability is not high,the spatial imagination ability is insufficient,and it is difficult to understand the relationship between some movements.These factors all bring difficulties to students' learning geometry.Students' interest in geometry learning is low or lacks self-confidence,and even a few students appear tired of geometry.However,with the emergence of "geometric drawing board" aided mathematics teaching,a new door has been opened for geometry teaching.According to the "Geometry Sketchpad" features and the characteristics of junior high school geometry teaching,we can see that "Geometric Sketchpad" can optimize geometry teaching and can play a greater role in geometry teaching.How to effectively use Geometry Sketchpad in junior high school geometry teaching is worth our educators' deep thinking.Therefore,this paper mainly studies from the following aspects:1.Understand the application status of "geometric drawing board" in junior middle school geometry teaching.2.Understand how teachers apply "geometric drawing board" in geometry teaching.3.What is the effect of "geometric drawing board" in geometric teaching?This study uses all junior middle school mathematics teachers and some students from Shenzhen XX Middle School and Dongguan XX Middle School as research subjects.The literature method,questionnaire survey,interviews,classroom observation,case study,and comparative research law.According to the research results,selecting the appropriate teaching content and using "geometric drawing board" in teaching can enrich the teaching methods of teachers to a certain extent.It makes up for the deficiency of traditional teaching,helps students to learn geometry better and raises their interest in learning geometry.At the same time,the use of geometric drawing board for classroom interaction highlights the initiative of students in learning.The effect of using "geometric drawing board" in geometry teaching shows that it is easier for students to understand abstract and dynamic geometric problems,and the effect of learning is also improved.Of course,there are some problems and difficulties in implementing the geometric teaching process by using "geometric drawing board",which need to be solved step by step in the further in-depth study.
