Research On The Application Of Inquiry Teaching In High School Stereo Geometry

In 2018,the Ministry of Education promulgated the Standard of Mathematics Curriculum for Senior High Schools(2017 edition).In this standard,it clearly points out that various learning methods,such as independent thinking,independent learning and cooperative communication,should be advocated to stimulate students' interest in learning mathematics,foster good learning habits and promote the development of students' practical ability and innovative consciousness.The part of solid geometry is not only the key but also the difficult point in high school mathematics.In this part,the position of "plane and plane parallel" is extremely critical,and in the past research,there are few studies on this aspect.By consulting a large number of literature about mathematical inquiry,the use of textbook inquiry content,the inquiry teaching of solid geometry and the parallel inquiry teaching of plane and plane,the core concepts are defined,which lays a theoretical foundation for this study.The research questions are as follows: What is the current situation of inquiry-based teaching of three-dimensional geometry "plane and plane parallel" in senior high schools in the research area? What are the factors influencing the implementation of the inquiry teaching of solid geometry in senior high school? What are the suggestions to improve the quality of inquiry teaching of solid geometry in senior high school? At the same time,it collects the strategy research of inquiry teaching,which provides a reference for the analysis of the influencing factors behind.This research adopts the methods of literature research,questionnaire survey,classroom observation and interview.Firstly,the literature is sorted out and summarized,questionnaires and interview outlines are compiled,and the survey tool has been revised many times by soliciting the opinions of high school front-line teachers.Secondly,this study chooses a provincial,municipal and high school in Gansu Province to select some students and mathematics teachers in each school.At the same time,I listened to the corresponding classroom teaching and collated and summarized.Finally,I collated and analyzed the data combined with teacher interviews.By investigating the current situation of inquiry teaching in the area of "parallelplane and plane",this paper analyses the current situation and influencing factors of inquiry teaching in high school solid geometry,and draws the following conclusions:firstly,there is a lack of reasonable evaluation criteria for the solid geometry part;secondly,it pays too much attention to the results and neglects the cultivation of students' interest in learning solid geometry;thirdly,in the middle school,there is a lack of reasonable evaluation criteria for In the process of solid geometry teaching,teachers' effective guidance is lacking.Finally,the inquiry teaching of solid geometry becomes a mere formality.According to the actual situation,the following suggestions are put forward: first,teachers should change traditional teaching concepts in the teaching of solid geometry;second,students need to develop good inquiry learning habits in the study of solid geometry;third,some "transitional knowledge" should be set up in the corresponding position of textbook solid geometry,and a reasonable evaluation mechanism should be formulated;fourth,schools need to improve multimedia settings.We will establish more laboratories,train teachers,increase books,journals and journals on solid geometry,and carry out activities such as "Mathematics Interest Group" on solid geometry.
