The “Three Meetings, Four Basics, and Six Competencies of Mathematics”
"Three Meetings"
Be able to observe the real world from a mathematical perspective
Mathematics provides people with an observation method to understand and explore the real world, discover quantitative relationships in the real world, and understand the mathematical principles behind natural phenomena.
Mathematical vision is mainly manifested in abstract abilities, including number sense, quantity sense, symbolic awareness, geometric intuition, and spatial concepts.
When you see an apple and two oranges, you can realize that there is a quantitative relationship such as "1" and "2". This is the embodiment of number sense;
Having a relatively accurate perception of the size, length, weight, etc. of objects is a manifestation of the sense of quantity.
Being able to use specific symbols to represent mathematical concepts and operations is symbolic awareness.
Geometric intuition is the use of geometric figures to understand and analyze mathematical problems.
The concept of space is the understanding of the shape, position, size, etc. of objects in space.
Ability to use mathematical thinking to think about the real world
Mathematics provides people with a way of thinking to understand and explain the real world. Through mathematical thinking, we can reveal the essential attributes of objective things and establish a logical connection between mathematics and the real world.
Mathematical thinking is mainly manifested in computing ability, reasoning awareness or reasoning ability.
Computing ability not only refers to accurately performing mathematical operations, but also includes understanding the principles of operations and choosing appropriate computing methods based on actual conditions.
Reasoning ability includes logical reasoning and deductive reasoning. Reasonable reasoning is to make inferences through induction, analogy and other methods based on existing facts and experiences.
By observing the sum of the interior angles of some triangles, infer the sum of the interior angles of all triangles;
For example, deductive reasoning starts from general premises and reaches specific conclusions through logical deduction, such as proving the sum of the interior angles of a specific triangle based on the sum of the interior angles of a triangle theorem.
Able to use mathematical language to express the real world
Mathematics provides people with an expression to describe and communicate the real world. Through the language of mathematics, natural phenomena, quantitative relationships and spatial forms in daily life can be described simply and accurately, and simple concepts can be constructed in real life and other subjects. Mathematical models, express and solve problems, and form reasonable judgments or decisions.
Mathematical language is mainly represented by data awareness or data concept, model awareness or model concept, and application awareness.
Data awareness refers to the sensitivity to data and the ability to recognize the information and patterns contained in the data;
Model awareness is the ability to abstract practical problems into mathematical models and solve and apply them, such as establishing equation models based on actual travel problems to solve;
Application awareness means being able to actively use mathematical knowledge and methods to solve problems in life and recognizing the practical value of mathematics.
"Four Basics"
1. Basic knowledge: basic concepts, theorems, formulas, etc. in mathematics.
2. Basic skills: calculation, reasoning, drawing and other skills in mathematics.
3. Basic ideas: such as the idea of combining numbers and shapes, the idea of classification discussion, the idea of functions and equations, etc.
four major ideas
Function and Equation Thoughts
The idea of functions and equations is to solve problems by establishing functional relationships or using equations;
Classify discussion ideas
The idea of classification discussion is to classify and solve problems according to different situations;
Combining Numbers and Shapes Thoughts
The idea of combining numbers and shapes is to transform numbers and shapes into each other to solve problems intuitively and vividly;
Transformation and Reduction Thoughts
The idea of transformation and reduction is to transform complex problems into simple ones, and unfamiliar problems into familiar ones.
4. Basic activity experience: experience accumulated through mathematical activities, such as inquiry, cooperation, communication, etc.
"Six Qualities"
1. Mathematical abstraction: abstract mathematical concepts and quantitative relationships from specific situations.
2. Logical reasoning: reasoning and argumentation according to logical rules.
3. Mathematical modeling: Use mathematical knowledge to build mathematical models to solve practical problems.
4. Intuitive imagination: Use geometric intuition and spatial imagination to perceive and understand mathematical problems.
5. Mathematical operations: Perform mathematical operations and solve problems.
6. Data analysis: Collect, organize, and analyze data, and extract useful information for inference and decision-making.
