Based on your own understanding, talk about why the Standards set up core concepts

Mathematical concepts are abstract things, which are the reflection of the essential attributes of the spatial form and quantitative relationship of objective things in reality in people's minds, it is the cornerstone of the formation of the written knowledge system, the first element of logical thinking, and one of the ways to master the quality of teaching. Now I will try to talk about some practices in teaching from the aspects of introducing, explaining, and consolidating concepts.

Introduce concepts, stimulate interest, emphasize methods, trigger thinking, and make students love learning. Interest is the best teacher, and only when students are interested in the knowledge they want to learn can they love to learn, know how to learn, be willing to learn, and be good at learning. Therefore, in the concept teaching, I put forward questions that meet the internal needs of students according to the teaching content, stimulate students' good learning motivation and desire for knowledge, and make students' spirits quickly enter the best state, which must be "introduced".

1. Intuitively introduce students in connection with the actual life of students.

Using the actual life of students and some examples and things they are familiar with, the concepts are explained, so that students can obtain perception, appearance and other perceptual materials to summarize mathematical concepts, from concrete to abstract.

2. Introduce the new with the old and pave the way and build bridges.

Introduce the new with the old, pave the way and build bridges. Some concepts are reasoned on the basis of students' original knowledge, and new concepts are often the development and extension of old concepts, using old knowledge to lead to new concepts, and cultivating the logic of students' thinking.

3. Hands-on calculations and discovery of new knowledge.

There are many concepts that are not easy to introduce in practice and have little connection with old concepts, in which they can be introduced through hands-on calculations by students.

How to guide students to explore knowledge, reflect the main role of students, and cultivate their logical thinking ability is the core issue of concept teaching. Therefore, after the concept is introduced, the teacher must clearly reveal the connotation and extension of the concept to the students in teaching, and grasp the essential attributes of the concept. In this way, students can derive the meaning of the multiplication commutative law through calculation, observation, comparison, and induction, clarify its characteristics, form clear concepts, and know the use, so as to make some calculations simple and improve the efficiency of students' calculations.

How to establish the concept of maritime rights and interests and maritime defense, and talk about your own understanding and thinking. Ask for 300-400 words...There are many types of maritime rights and interests, including territorial sea rights and interests in the exclusive economic zone.

The Curriculum Standards put forward six basic concepts, which mainly reflect the overall goal of mathematics education to focus on student development, and the two basic strategies to achieve this goal.

Specifically, it is manifested in the following aspects:

1) Mathematics curriculum objectives with a focus on human development.

1.Everyone learns valuable mathematics.

2.Everyone has access to the necessary mathematics.

3.Different shouters develop mathematically differently.

2. Hail learned) to change the structure and presentation of mathematics curriculum content.

1 Mathematics education for all students should be what students need in the future, have a realistic background, be interesting and provocative.

3) Improve the way mathematics is learned and evaluated.

1. Advocate meaningful learning: independent exploration, hands-on practice, cooperation and communication, and innovation.

2. Implement a pluralistic and diversified evaluation method.

Quality management principles.

The eight quality management principles are the guiding principles used by top leaders to lead organizations in performance improvement and form the basis of the ISO9000 family of standards, including:

1) Focus on the customer;

2) leadership;

3) Full participation;

4) process methods;

5) a systematic approach to management;

6) Continuous improvement;

7) fact-based decision-making methods;

8) Mutually beneficial relationship with suppliers.
