Teaching Design And Practice Of Improving The Quality Of Mathematics Learning For High School Students Based On The Network Sketchpad

Using modern educational technology to teach conic curve is the teaching requirement of conic curve in "ordinary high school mathematics curriculum standard(2017 Edition)".Whether it is the teaching resources expedited by the progress of the times,or the teaching requirements put forward by the teaching development research,or a variety of teaching methods used by teachers in the teaching process,the purpose is to improve the quality of high school students' mathematics learning.This paper takes conic as the teaching content,adopts four research methods:literature research method,comparative research method,experimental analysis method and interview method,applies network Sketchpad to make courseware,carries out teaching design,and studies how network Sketchpad teaching improves the quality of senior high school students' mathematics learning through practical teaching.Firstly,the application of dynamic geometry software in mathematics teaching is reviewed,and the promoting effect of the integration of geometry software and mathematics on students' learning is defined.Through the analysis of the conic part of the new college entrance examination questions since the implementation of the new college entrance examination,the status of conic in the new college entrance examination is highlighted;Through the comparison of three representative dynamic geometry software,it shows the unique advantages of network sketchpad;Through the research on the teaching requirements of conic curve in "ordinary high school mathematics curriculum standard(2017 Edition)" and "interpretation of new curriculum standard of ordinary high school",this paper provides guarantee for selecting network Sketchpad as teaching software and conic curve as teaching content.Secondly,based on APOS theory and problem driven theory,this paper puts forward the basic principles of applying network Sketchpad to assist conic curve teaching,and designs the teaching design of applying network Sketchpad to assist conic curve teaching under the guidance of theoretical basis and in accordance with the requirements of general high school mathematics curriculum standard(2017 Edition).Finally,using the teaching design,combined with teaching practice,through the analysis of students' academic performance,it shows that the application of network Sketchpad has a certain effect on improving students' academic performance;Through the interviews with the students,it shows that the students are interested in learning and have the confidence and expectation to learn mathematics well;Then from the two aspects of students' academic performance and emotional experience,it shows that the conic curve teaching based on the network Sketchpad has a certain role in promoting the quality of high school students' mathematics learning.This paper aims to provide more teaching resources and teaching methods for front-line teachers through this research,hoping to make a contribution to the research of network Sketchpad and provide reference for teachers to seek to improve the quality of high school students' mathematics learning.
