In the field of education, the four-dimensional goal refers to the four-dimensional goal of the new curriculum reform, namely knowledge and skills, mathematical thinking, problem solving and emotional attitude.

1. knowledge and skills: students need to master the basic knowledge of various subjects and be able to apply this knowledge in practical problems.

2. Mathematical thinking: Students should be able to use algebra to express operations and geometric intuition, establish a sense of numbers, symbols and space, and develop image thinking and abstract thinking.

3. Problem solving: Students should learn to ask questions and acquire the ability to analyze and solve problems. At the same time, students should learn to cooperate and communicate, and initially form a sense of evaluation and reflection.

4. Emotional attitude: Students should actively participate in mathematics activities, exercise their will to overcome difficulties, establish self-confidence, understand the value of mathematics, be brave in questioning and seek truth from facts.

Four-dimensional (four-dimensional) describes the number of space-time coordinates in physics, which is composed of countless three dimensions, and three dimensions are composed of countless two dimensions. The composition of other high dimensions and so on. Dimensions with more than three dimensions are collectively called high dimensions. Dimension is a spatial concept, and different dimensions represent different spaces.
