Research On The Current Situation And Teaching Strategies Of High School Students' Flat Vector Learning

Nowadays,the application value of mathematics has been paid more and more attention.As a basic concept in mathematics and physics,its flexibility and simplicity make it a powerful tool for solving problems in algebra,geometry,physical mechanics,and electromagnetics.With the deepening of curriculum reform,the educational and practical value of vector has been gradually realized,which makes it be incorporated into middle school mathematics curriculum and occupy an important position.Vector skillfully combines number and shape,which provides new thought for students to solve problems.In addition,learning vector can effectively cultivate students' mathematical literacy such as mathematical abstraction,mathematical operation and spatial imagination.This study investigates the mastery of plane vector knowledge of high school students,and the mainly works as follows: First,on the basis of reading relevant literature,the study of plane vector teaching and learning is combed,and the specific content of plane vector is briefly analyzed.Secondly,develop research tools to investigate the second and third grade students of a middle school in Heze City under the premise of ensuring the reliability and validity of the questionnaire,and analyze the students' mastery of plane vector knowledge and problems in learning,combined with the teachers and students interview to try to find the reasons affecting students' learning plane vectors.Finally,it puts forward effective teaching suggestions based on the survey results.The survey has the following conclusions: First,students' mastery of the plane vector is at a moderate level,and there is no significant difference between male and female students in the plane vector learning,and the academic performance of the students in the third grade is significantly higher than that of the students in the second grade.Second,students have many problems in the study of plane vector,including: insufficient understanding of the actual background of plane vector,and has not yet established the concept of "free vectors";the learning of formulas and theorems is mainly based on mechanical memory and cannot be flexible Use the geometric meaning to solve problems;the application consciousness of plane vector is weak,and the text language cannot be skillfully converted into vector language.Based on the above research results,the teaching strategies put forward in this thesis include:focusing on the teaching of the actual background and concept of vector;paying attention to calculations to cultivate students' mathematics literacy,paying attention to application,exerting the role of vector tools;paying attention to teaching materials,and return to the foundation,training students to be good in mathematics study habits;and teachers should continuously improve their own information literacy.
