Overview of model concepts:
1, the concept of model mainly refers to a clear understanding of using mathematical models to solve practical problems. Knowing that mathematical modeling is the basic way to integrate mathematics with practice.
2. By comparison, we can find that the "model concept" in the 201version of the curriculum standard is close to the "model concept" in the junior middle school stage of the 2022 version of the curriculum standard.
The 3.2022 version of curriculum standard puts forward that core literacy has integrity, consistency and stages, and has different performances in different stages. Therefore, the 2022 edition of mathematics curriculum refines "model thought" into "model consciousness" and "model concept".
4. Primary schools pay more attention to cultivating students' "model consciousness" and their initial understanding and application of mathematical models, while junior high schools pay more attention to cultivating students' "model concepts". Both of them are one of the main forms of mathematical language in compulsory education.
The method of developing the concept of student model;
1, carefully select materials, and let students experience the process of solving practical problems. Good materials are the foundation of children's mathematical modeling. Familiar and typical materials help children fully experience the process of observation, analysis, abstraction and generalization, thus forming a general model concept.
2. With typical examples, let students feel that mathematical models can solve a class of problems. The 2022 edition of the curriculum standard proposes to recognize the common quantitative relations in the second phase of "quantitative relations". Version 20 1 1 of curriculum standard not only keeps the multiplication model of "distance = speed x time, total price = unit price x quantity", but also adds the addition model of "total amount = component+component", which can be regarded as a typical model.
3. Carry out interdisciplinary theme activities and highlight the application of mathematics. We should consciously carry out some interdisciplinary theme activities to enrich students' understanding of mathematics application and let them experience the process of comprehensively applying knowledge and methods to solve problems. Most importantly, students will feel the important role of mathematics in this process.
