Teaching Research On Improving The Learning Quality Of High School Students From The Perspective Of Mathematics Core Literacy ——Taking "Plane Vector And Its Application" As An Example

Learning quality is the representation of the effect of students' acquisition and mastery of the knowledge they have learned in a certain learning stage,which can be evaluated by observation.In order to promote students' key abilities better,this dissertation researches mainly on how to teach to improve the learning quality of high school students from the perspective of mathematics core literacy by combining the teaching content of plane vectors.When using the literature research method to study,we deepen the studying and understanding of the existing mathematics core literacy,learning quality,plane vector,and related important theoretical foundations,and propose the corresponding research content of this dissertation;when using the survey method,we use mainly the test papers.In the form of questionnaires,high school students are taken as the research objects to understand the existing problems of students' learning quality in their learning process of plane vector.The conclusions of this study are given as follows:(1)An important interrelationship between mathematics core literacy and learning quality is analyzed and proposed,that is,the mathematics core literacy is evaluated with learning quality as an observable carrier,and on the contrary,the improvement of learning quality also promotes the cultivation of mathematics core literacy.(2)The senior high school students are investigated in the form of test papers,and general problems which affect the students' learning quality for plane vector are found by collecting and analyzing the investigation data.The problems for the students include weak basic knowledge,confusion of concepts,rigidity of formula theorems,lack of effective reflection and summary,neglection of knowledge migration,and dependence on reference answers.(3)The senior high school students are investigated in the form of questionnaires.Some teachers are interviewed.The problems and their reasons which affect the students' learning quality for plane vector are analyzed from three aspects: emotion,students and teachers,and give the.For the emotion,the students do not have a strong interest in learning,they are unclear with learning motivation,they subjectively believe that plane vector abstraction is difficult to understand,they are lack of teacher's motivation and help between classmates in their learning process,and their parents focus on results over process,etc.For the students,they have improper learning attitude,unscientific learning methods,insufficient ability of knowledge transfer,weak cognitive ability of Meta,etc.For the teachers,they do not update timely the content of new textbooks,their teaching methods are too traditional to lack innovation,their teaching methods are too simple and rigid,their teaching concepts do not keep up with the pace of the new curriculum reform,and they are not rigorous and serious enough to collect and treat the students' academic feelings.(4)According to the analysis of the general problems found in the investigation and research,some teaching countermeasures and suggestions to improve the senior high school students' learning quality of plane vectors are put forward,i.e.,the students should pay importance to the learning of basic knowledge,improve their computing ability,overcome their operational obstacles,and understand accurately the importance of plane vectors.The teachers should strengthen the analysis idea and logic construction for solving plane vector problems,find specific learning methods for plane vector,and give the students with understanding,support and motivation when they are learning plane vectors.The teacher should avoid their teaching attitude of "result-oriented and process-oriented",pay attention to the improvement of students' mobility,learning and the penetration of mathematical ideas and methods,and cultivate students' metacognitive ability.(5)Based on the proposed teaching countermeasures and suggestions,two teaching cases of "The Additive Operation of Plane Vectors" and "The Problem of Maximal and Minimal Value and Valuing Range of Triangles" are designed with the goal of improving the senior high school students' learning quality for plane vectors and developing their core literacy of mathematics.The teaching cases provide the mathematics teachers teacing in classroom with certain reference when they teach the content of plane vectors.This helps the students learn the plane vector better.
