Based On The General High School Mathematics Curriculum Standard (2017 Edition) Under The Space Vector Content Exploration And Teaching Research

This paper explores the content of spatial vectors in high school mathematics courses and makes a detailed study of their teaching.Prior to the promulgation of the General High School Mathematics Curriculum Standard(2017 Edition),the content of the high school space vector only included the addition of space vectors and stereo geometry,space vectors and algebra.It will have a great impact on the original education model and curriculum structure.The important value and function of the combination of spatial vector and algebra have been widely concerned in mathematics and education circles.However,so far,there is little research on this aspect,and there is a lack of empirical research on teachers and students.With the background of new curriculum reform and my educational practice,the research focused on the content and teaching of spatial vector and three-dimensional geometry and spatial vector and algebra has important practical significance for further understanding the application of spatial vector in teaching.This article mainly expounds the article viewpoint from the following aspects:The first part compares and analyzes the contents of the ordinary high school mathematics curriculum standard(experimental version)(hereinafter referred to as the experimental version of the curriculum standard)and the ordinary high school mathematics curriculum standard(2017edition)(hereinafter referred to as the 2017 version of the curriculum standard).There are big differences in the design basis and content structure of the course standard,especially in the space vector content.The 2017 version of the course label has made a large adjustment to this part of the content.In terms of design basis,the 2017 version of the curriculum standard pays more attention to the individual differences of students,proposes the educational task of“Cultivate human morality”,and pays attention to cultivating the core literacy of students;in the content structure,breaks the original curriculum structure and divides the curriculum into two parts.Compulsory courses,optional compulsory courses and elective courses make the course structure more in line with the individual development of students and meet the needs of different students.The 2017 version of the standard space vector content is more abundant than before,more selective,clear and explore this part.The change of knowledge provides a theoretical basis for the next research teaching.In the second part,the theoretical analysis of the space vector teaching under the new curriculum concept is carried out on the basis of the theory of the recent development zone of Vygotsky.According to the constructivist learning theory,the space vector teaching should pay attention to the construction of students' own knowledge,form their own theoretical system,and carry out meaningful learning.According to Ausubel's motivation theory,teachers should pay attention to guiding students to produce correctness in teaching.Learning motivation,promotingstudents' self-internal drive to improve their views;on the basis of which students continuously explore the idea of discovering knowledge;according to Vigos Based on the theory of recent development zones,it is proposed that teachers should be good at discovering students' recent development areas and promote the improvement of students' knowledge and ability.On the basis of theoretical analysis,the theory is applied to practical teaching.In the third part,the experimental research on the current situation of spatial vector content teaching is carried out.Aiming at the existing teaching problems,the student test papers are designed.By analyzing the test results,it is found that students lack the knowledge,and the spatial imagination ability,logical reasoning ability and computing ability need to be improved.From these problems,we can get the teaching enlightenment: pay attention to the teaching of basic knowledge,strengthen the cultivation of computing ability,and cultivate students' ability to choose the method of solving problems reasonably.The test results found the shortcomings in the current teaching to improve teaching.Space vector and algebra knowledge have been added to the new curriculum standard.This part of the knowledge has not really been implemented in the classroom.For this part of the research,the teacher interview method is adopted.The purpose is to understand the in-service teachers' views on the influence of space vector and algebra on student learning.Through the analysis of interview results,it is found that teachers support the introduction of space vector and algebra into high school textbooks.This part of knowledge can enrich teaching content and expand students' knowledge.On this basis,give some suggestions for teaching: fully prepare lessons,prepare for class,give full play to the guiding role of teachers,and effectively guide students.The fourth part,based on the 2017 version of the curriculum standard,conducts a teaching study on the space vector content.According to the teaching theory,the practical teaching process and teaching strategies are studied,and the teaching cases are given according to the design pattern.In the teaching process,the main design: understanding the individual and learning needs of students,determining the teaching objectives,creating situation design tasks,guiding students to explore knowledge,students summing up the knowledge structure,and guiding evaluation according to feedback.Teaching strategies are given in combination with teaching steps: creating situations,solving problems,creating environmentally-friendly teaching,and teaching instructional strategies.Based on the above analysis,the linear correlation teaching case of vector group is given,in order to give reference to space vector teaching.
