This is the requirement of the new mathematics curriculum standard for teaching and learning, emphasizing the connection between mathematics and life.
Strictly speaking, it's not mathematical thinking. Can be understood from the perspective of teachers and students:
Judging from the teaching of our math teachers, it includes two meanings: one is to thoroughly understand the teaching materials and make good use of them; Second, don't be limited to textbooks, you can jump out of textbooks. Understand the textbook thoroughly, so that you can use the knowledge of the textbook to solve practical problems; Jumping out of textbooks means not confining students to the sea of textbooks, materials and problems, and establishing a teaching concept based on student development and a student view of "students are developing people".
In the same way, some scholars put forward the concept of "big language", which opened a new world for Chinese and Chinese teaching, and led to "transformative" changes in people's concepts and understanding of Chinese. The concept of Chinese equates the meaning of Chinese and the meaning of Chinese learning with the meaning of life.
