I have been busy with the training activities of "Mathematics Core Literacy and Teaching" these days. Listen to the northeast

Professor Ma's lecture on Understanding the Core Literacy of Primary Mathematics is an elective course.

Four courses related to the core quality of mathematics. Through learning, I have a good understanding of "the core quality of mathematics"

Have a deeper understanding: learning mathematics is to master a number constructed in modern scientific language.

Learning knowledge, ideas and methods; Master a rational way of thinking and mathematical skills; Acquire mathematical ability

Force, forming mathematical consciousness or habits, that is, mathematical concepts; Cultivate mathematics quality. These, all

It can be called mathematical literacy.

To cultivate students' mathematical literacy, I think we can start from the following aspects:

First, dig deep into the mathematical ideas and methods in the teaching materials for teaching.

Mathematical thought is the essence of mathematics and its objects, mathematical concepts, propositions and mathematical methods.

Understand. Mathematical method is the method and strategy to solve mathematical problems. Primary school mathematics textbook system package

There are two main lines, one is mathematical knowledge, which is a bright line written in textbooks, and the other is mathematical thinking.

Yes, it's a dark line. Only by mastering the mathematical thinking method can we manage it from the whole and essence.

Solve teaching materials; Only by digging deep into the mathematical thinking method of textbooks can we design textbooks scientifically and flexibly.

Teaching methods. Especially the textbook of Beijing Normal University, in the form of scenario+question string, if you don't go,

Digging deep into textbooks, students often don't know what to teach and what to learn. Such as a positive ratio and a negative ratio.

This part is permeated with the idea of function.

.

Two types revealed in the concepts of direct ratio and inverse ratio

The relationship between related quantities is essentially a functional relationship. This part of the textbook comes from luck.

Study the proportional relationship between quantity and quantity from the perspective of movement and change, and use forms and tables acceptable to primary school students.

The method of reaching introduces the preliminary functional idea. Teachers should draw pictures when dealing with this part of teaching materials.

List and other intuitive ways, make the finishing point to emphasize the "change" of quantity and highlight "two correlations"

The correspondence between quantities. Mathematical thinking method is not only a necessary condition for primary school students to master mathematical knowledge.

about

,

It is also the basis for further study of mathematics. It is better to "teach people to fish" than to "teach people to fish"

.

know

The memory of knowledge is temporary, and the mastery of thinking methods is long-term. Knowledge benefits students for a while.

,

Ideas and methods benefit students for life.

(2) Let students express their thoughts and methods in mathematical language.

The formation of mathematical literacy is closely related to language, and the correct mathematical language can be more accurate.

It clearly reflects a person's thinking process and shows the development level of thinking ability.

because

Well,

We should cultivate students' language ability,

Learn to express mathematical thoughts in mathematical language,

Like studying.

Root; Someone said:?

Students can tell the calculation in an orderly way under their own experience.

Methods and processes cultivate the expressive ability of language.

When teaching,

It is a very effective way to train students to think loudly while operating.

Learn how to express your thoughts and opinions.

In operation,

Students are bound to think;

how shall I put it,

Move, why do you want to put it like this? What's the best way to move? Students' thinking has been exercised,

So as to help students concretize and visualize abstract language. Students only need to follow the operation process.

Speak your own thoughts, from which you can get the connotation of knowledge and express it easily in language.

My own thoughts. This combination of nature, students learn interesting, speak enthusiastically, complement each other, * * * *

With the improvement of the condition.

(C) Let students use mathematics in their daily lives.

Life is inseparable from mathematics, which comes from life, when mathematics is closely related to children's life.

Combined, mathematics is alive and full of life, in order to stimulate children to learn and solve problems.

Interest is the source of stimulating children's thinking and creativity. Teachers should actively create life situations to make

They learn to use mathematics in their lives, and get to know relevant knowledge through activities, rather than connecting with reality.

Disconnecting and passively accepting knowledge can only make students feel close because of the math problems in life.

Cut, naturally. Invisibly induce students' psychological tendency to explore actively, so that everyone can learn.

Mathematics, learning mathematics knowledge in life.

(D) Guide students to look at things around them from a mathematical perspective.

There are many math problems around us.

Guiding students to abstract problems in life in teaching

For mathematical problems, further revealing the relationship between concrete things and abstract concepts will not only deepen the knowledge learned.

Understanding knowledge helps to improve the ability to solve problems. For example, help the residents in the building calculate their monthly payments.

Calculating utility; Calculate the number of floor tiles used by indoor decoration users to spread the floor, spray the wall and

How much paint does the roof need to buy?

According to the planting area and the number of seedlings on Arbor Day,

Calculate the line spacing,

Plant distance? Students think these questions are real and interesting. Mathematics is everywhere around them, and the more they learn, the more energetic they are.

Head, form a good habit of integrating theory with practice.

Mathematical literacy also includes acquiring mathematical ability and developing mathematical quality. And the cultivation of mathematical literacy.

In the final analysis, it depends on every math teacher.

Only every teacher thinks of himself as an expert.

Family, students, their parents, society and other partners jointly build a new curriculum; Think you have the present.

Explorers who represent educational ideas, know how to reflect on technology and are good at cooperation not only cultivate students' mathematics.

Literacy is not a problem, nor is it a problem to train students to become people with harmonious physical and mental development. In this way, this class

Be mentioned

"Everything is for the students,

For all students "

It will no longer be a beautiful slogan.
