Investigation And Research On The Development Level Of Mathematical Abstract Literacy Of Senior High School Students

The core accomplishment of mathematics discipline is the concentrated embodiment of the goal of mathematics curriculum,and it is the correct values,necessary character and key ability formed by students through the study and application of mathematics.As the first of the core literacy of the six disciplines,"Mathematical Abstract Literacy" is of special significance to the development of students' mathematical thinking and innovative ability,and to help students grow and develop.Therefore,the study of students' mathematical abstract literacy is of great significance to mathematics teaching.This study adopts the methods of literature research and investigation,according to the division of the level of mathematical abstract literacy in "Mathematics Curriculum Standard of General Senior High School(2017 Edition)",with the content of "plane vector" as the carrier,investigates the current situation of the development level of mathematical abstract literacy of senior high school students in a senior high school in Tianshui,and draws the following conclusions:(1)On the whole,all the students reached level 1 and all met the requirements for high school graduation;2/3 of the students reached level 2,accounting for 72.46% of the total population,meeting the requirements of the college entrance examination;27.54% of the students reach level 3,which meets the requirements of the core literacy of mathematics,from which we can see that the level of students' abstract literacy of mathematics is not high,although all of them meet the requirements of senior high school graduation.however,the proportion of students who can meet the requirements of the core literacy of mathematics is very small.(2)When it comes to the four aspects that reflect the core literacy of mathematics,students perform best in knowledge and skills,60.83% of students can reach level 3;in terms of thinking and expression,83.05% of students can reach level 2,but few students meet the requirements of the general method of perception of mathematics;in terms of situations and problems,students are poor in abstracting mathematical problems in comprehensive situations.Students have the worst performance in communication and reflection,accounting for 34.75% of the students who have reached level 1,and very few students have reached level 3,accounting for only 6.36% of the total number of students,indicating that most students have great difficulties in communication and reflection.In view of the above senior high school students' mathematics abstract literacy level,this paper puts forward the following teaching strategies:(1)Create diversified situations to guide students to participate in mathematical abstract process;(2)Pay attention to the essence of mathematical knowledge,grasp classroom effectiveness,and guide students to experience mathematical abstract process;(3)Pay attention to classroom questioning skills in the process of teaching.strengthen mathematical thinking and language training,guide students to think independently;(4)Pay attention to classroom communication,accumulate abstract experience in the process of communication,and cultivate a sense of reflection.
