Investigation And Research On The Present Situation Of Mathematical Abstraction Core Literacy Of Senior High School Students

The Ministry of Education puts forward the six core literacy of mathematics in the "Standards for Senior High School Mathematics Curriculum(2017 Edition)".The core of mathematics abstraction is the first of its kind.It plays an important role in the formation and application of students' mathematical knowledge.It is of great significance to evaluate and study the current status of high-level students' mathematical abstract core literacy.This paper adopts the literature research method,the questionnaire survey method and the statistical analysis method.Based on the mathematics abstract core literacy evaluation standard framework constructed by the General Senior High School Mathematics Curriculum Standard(2017 Edition),four dimensions,three levels and four levels are constructed.Evaluation System.The high school students' mathematical abstract core literacy questionnaire and the high school students' mathematical abstract core literacy test questions were designed.A sample survey was conducted among first-year students in a high school.The collected data were statistically analyzed using Excel and IBM SPSS Statistics 23.The main conclusions of the paper are as follows:Through the questionnaire analysis,it is found that the high-level students' mathematical abstract core literacy has the following problems:(1)students are not good at the connection of mathematics knowledge,and do not develop the habit of regular summarization;(2)the connection between mathematics and real life is less,and the application consciousness is weaker;(3)The degree of love for mathematics and the importance of mathematical abstract core literacy need to be strengthened;(4)Teachers have begun to pay attention to the cultivation of students' abstract core literacy,but the results are not significant.The causes of these problems,in addition to the students themselves,the teacher education method is also crucial to the development of students' mathematical core literacy.Through the statistical analysis of the test volume,it is found that the vast majority of students reach the level one,more than half of the students reach the level two,and about half of the students reach the level three.High school students have a medium level of abstraction in mathematics.Among the four dimensions that are specific,(1)the knowledge and skill dimensions perform well,and the student function knowledge is well mastered,but the ability of related knowledge connections needs to be strengthened.(2)The thinking and expression dimensions performed well.(3)The communication and anti-thinking performance is general,the communication ability of students and others,and the ability to reflect on mathematical concepts and mathematical principles need to be strengthened.(4)The situation and problemdimensions are poorly expressed.Different situation types will affect the mathematical abstract core literacy level of the situation and problem.Through the difference test,there is no significant difference between the core level of mathematics abstraction and the gender of the students.There is a significant difference between the experimental class and the parallel class,which is closely related to the development of students' usual habits.In view of the statistical results of the high-level students' mathematical abstract core literacy status and the problems common to students,the following suggestions are made:(1)creating a teaching situation that is conducive to the development of students' abstract core literacy;(2)paying attention to the systematic knowledge of mathematics and the connection of knowledge;(3)Strengthen the reading comprehension ability and language expression ability of high school students;(4)Strengthen the problem-solving training and pay attention to reflection.
