Research On High School Flat Vector Teaching Based On The Cultivation Of Abstract Literacy

In recent years,core literacy has become a hot topic in the education field.Therefore,the core literacy of mathematics has also attracted the attention of mathematics researchers and teachers.As the first of the six core literacy,mathematics abstract literacy can help students to carry out rigorous,orderly and concise training of thinking expression,which is of great significance for students' learning and development.Finding the right carrier is the key step in cultivating students' mathematical abstract literacy.As an important concept of modern mathematics,vector has both algebraic and geometric features.It is a carrier of digital combination and a natural bridge between communication geometry and algebra.Therefore,in the context of core literacy and considering the important position of vector teaching in high school mathematics,this thesis,regards the chapter of planar vector as the carrier,aims to study the plane vector teaching strategy based on abstract literacy training.This paper analyzes the content of the plane vector chapter of the new curriculum standard,and the feasibility of implementing mathematical abstract literacy.On the basis of theoretical research,the specific teaching strategies are given according to the four concepts of vector concept,operation,theorem and application.Specific instructional design was implemented in the classroom according to the teaching strategy.According to the standard of high school mathematics curriculum,the test volume is compiled according to the level of mathematical abstract literacy.Combined with the teaching practice,the level of mathematical abstraction achieved by students is tested.According to the standard of high school mathematics curriculum,the test volume of mathematics abstract literacy is divided,and combined with teaching practice,the level of mathematical abstraction achieved by students is tested.The test results show that students who reach level one account for 100%,reach level two account for 70.37%,and reach level three account for 29.63%,which proves that the previous teaching strategies have been effective.But specifically related to these four aspects,the performance of students is uneven.Students' knowledge and skills,thinking andexpression testing levels are comparable,but the situation and problems,communication and reflection level needs to be improved.It shows that the previous teaching strategy has reached the expected part,and some have yet to be improved.Based on the test results,improvement measures are given.
