1. Introduction to Mathematics Core Literacy
The core literacy of mathematics discipline is the concentrated expression of the mathematics curriculum objectives gradually formed and developed by students in the process of mathematics learning and application, and the comprehensive expression of thinking quality, key ability, emotion, attitude and values with the basic characteristics of mathematics. The core literacy of mathematics discipline includes: mathematical abstraction, Logical reasoning, mathematical modeling, intuitive imagination, mathematical operation and data analysis.
Second, the core literacy.
In order to implement the requirements of the 18th and 19th National Congress of the Communist Party of China on moral education and further deepen the curriculum reform of basic education, the Ministry of Education organized more than 260 experts to revise the curriculum plan of ordinary senior high schools and the curriculum standards of Chinese and other subjects 14, which took four years to complete and was issued at the end of 20 17. In the new curriculum plan and curriculum standards, all disciplines put forward the core literacy of disciplines concisely for the first time.
Third, the significance of core literacy
The core literacy of mathematics is the concentrated expression of the objectives of mathematics curriculum, the comprehensive expression of thinking quality, key ability, emotion, attitude and values with the basic characteristics of mathematics, and it is gradually formed and developed in the process of mathematics learning and application. The core literacy of these mathematics disciplines is relatively independent and blended with each other, which is an organic whole.
Contents of core literacy in mathematics:
1, mathematical abstraction
Mathematical abstraction refers to the abstraction of quantitative relations and spatial forms in order to obtain the literacy of mathematical research objects. It mainly includes: abstracting the relationship between mathematical concepts and concepts from the relationship between quantity and shape, abstracting general laws and structures from the specific background of things, and expressing them in mathematical language.
2. Logical reasoning
Logical reasoning refers to the completion of deducing other propositions from some facts and propositions according to rules. It mainly includes two categories: one is reasoning from special to general, and the main forms of reasoning are induction and analogy; One is from general to special reasoning, and the main form of reasoning is deduction.
3. Mathematical modeling
Mathematical modeling is the result of mathematical abstraction of real problems, expression of problems in mathematical language and establishment of models to solve problems in mathematical methods. The process of mathematical modeling mainly includes: finding problems, raising problems, analyzing problems, establishing models, determining parameters, calculating solutions, testing results, improving models, and finally solving practical problems.
