After the new curriculum reform, the concept of core literacy has been put forward in primary education, which has changed the training objectives and teaching methods in the original teaching, promoted the transformation from single teaching to quality teaching, realized the equal emphasis on ability and character, and promoted the all-round development of students.
In order to improve the quality of primary school mathematics teaching, teachers have studied and explored the core literacy in succession, striving to highlight the characteristics and value of core literacy in combination with teaching practice, so as to achieve the ultimate goal of primary school mathematics teaching. In this regard, under such an environmental background, it is of great practical significance to explore the practice and thinking of core literacy in primary school mathematics classroom.
First, the connotation of primary school mathematics core literacy
The core literacy of primary school mathematics is the comprehensive ability that primary school students should have to find, analyze and solve problems with mathematical knowledge after learning mathematics in primary school. According to the relevant requirements of mathematics curriculum standards, the core literacy that mathematics should cultivate mainly includes mathematical abstraction, logical reasoning, computing ability and personal literacy.
First, mathematical abstraction refers to the mathematical concepts and ideas formed in the process of summarizing the essential characteristics of representative things among many complex things and actively abandoning some irrelevant non-essential characteristics;
Secondly, logical reasoning means that students are good at finding and putting forward mathematical problems in their study, and then analyzing and solving them;
Thirdly, computing ability means that students can master the methods of oral calculation, estimation and written calculation. In the process of solving problems, you can flexibly choose the appropriate method to calculate; Fourth, personal accomplishment means that students can bring mathematics in life into the classroom, and at the same time, they can find practical problems in life with the mathematics knowledge they have learned in the classroom, and form a good habit of learning with an open mind and loving life.
In the concrete process of mathematics classroom teaching, teachers should carry out teaching based on the implementation of subject literacy, rather than blindly ignoring the cultivation of students' core literacy in order to achieve teaching objectives. The core literacy of mathematics can be understood as the discipline literacy that students should achieve beyond knowledge and skills in learning mathematics and make a breakthrough in emotion, attitude and values.
The focus of mathematics core literacy is no longer the knowledge and skills that students should acquire when studying mathematics, but that students can not only improve their mathematics scores, but also acquire some good thinking habits and develop a habit of thinking, discovering and discussing.
Second, the implementation of the basic path of discipline core literacy training and countermeasures.
1. Innovating teaching strategies to improve mathematics consciousness
In the process of primary school mathematics teaching, in order to achieve the goal of core quality education, teachers should innovate teaching strategies, combine inquiry teaching, situational teaching and flip classroom, understand the advantages and disadvantages of various teaching models, and choose and integrate them according to the actual teaching content.
At the same time, teachers should introduce modern information education methods into primary school classroom teaching, stimulate students' interest in learning mathematics, improve students' enthusiasm for participating in classroom teaching activities, and then realize the ultimate goal of primary school mathematics teaching.
2. Comprehensively expand the training path of content teaching.
Classroom teaching of basic content is the main channel to cultivate core literacy. In particular, the core literacy of a subject is inseparable from the acquisition of subject knowledge and the formation of subject ability and attitude. However, in the teaching of basic content, what quality a class focuses on is determined by the content.
This characteristic of subject core literacy is attached to the content, which suggests that we must also open up a teaching channel and implement the "tailor-made" training of subject core literacy, that is, meet the needs of literacy training and choose the appropriate content carrier, so that the subject core literacy can be cultivated more systematically and widely.
Programme for international student assessment endowed literacy with measurable connotation. They regard literacy as an internal condition for individuals to successfully meet the complex requirements and challenges of the situation in a specific situation and to successfully solve realistic and comprehensive problems.
From this point of view, in our current curriculum teaching reform practice, the "synthesis and practice" section published by People's Education Publishing House and the unique series of textbooks with expanded content "Mathematics Wide Angle" are effective carrier forms for cultivating the core literacy of the discipline. The existing practice shows that the teaching of basic content and the teaching of comprehensive expanded content can complement each other and form a joint force through continuous adjustment.
Therefore, it is reasonable to believe that in the process of cultivating core literacy, different areas of basic content have their own key training paths and special training paths for comprehensively expanding content, and they can also complement each other through continuous improvement on the basis of in-depth practice.
3. Strengthen the cultivation of thinking in images and abstract thinking.
As far as mathematics is concerned, it has many abstract things. As a qualified primary school math teacher, we should work harder to cultivate students' ability to combine abstract things with concrete things.
For example, solid geometry, many graphics are inseparable from students' imagination, and students need to integrate concrete images with abstract thinking in order to deal with mathematical problems effectively and quickly.
For example, when learning the knowledge of rectangular volume, teachers can guide students to imagine their own teachers and erase the roof and the surrounding solid walls, only lines exist, which is actually a rectangular structure.
But in real life, there are many similar examples, the essential things are divided, and the rest are essential and practical things. The combination of students' thinking in images and abstract thinking ability will help them face difficulties in their later lives, thus cultivating their observation ability and judgment ability.
4. Let students learn through independent inquiry.
"Independent inquiry" is a learning method advocated by the new curriculum reform. The purpose of the new curriculum reform is to realize people-oriented, let students return to the main position of classroom masters, free students from the "container of knowledge", realize "learning" as "learning", open students' minds, cultivate innovative spirit and cultivate innovative talents.
This requires teachers to pay attention to cultivating students' consciousness of independent inquiry. Teachers should take the knowledge in textbooks as the background, combine with real life, create teaching situations, let students feel that the learning materials are very close to life, and invest in learning with a positive "I want to learn" mentality. Teachers should boldly let students do it themselves, so that the knowledge they have learned will be preserved in memory for a long time.
The teacher is the booster, he pushes the students forward, and the students are the masters of learning. We should give full play to subjective initiative to improve ourselves, make good use of the teaching situation provided by teachers, actively integrate into the learning situation, and be good at observation, exploration and analysis.
More importantly, we should be good at cooperation, exploration and communication with our classmates. The collision of different ideas will make learning more efficient. Forming the consciousness of independent cooperation and inquiry is beneficial to the improvement of students' learning ability.
Third, the conclusion
In the process of primary school mathematics education, teachers should attach great importance to the cultivation of students' core literacy on the basis of imparting relevant mathematics knowledge and skills, guide students to participate in the construction and promotion of core literacy, and maximize the level of mathematics teaching.
