First, do a good job in teaching routines and cultivate students' good study habits.
Grasping the teaching rules and making students develop good study habits are the basis of improving the quality of classroom teaching. I have clear normative requirements for students' classroom learning, such as preparing school supplies before class, using exercise books and arranging homework time. I attach great importance to teaching students to preview, review, do homework, practice, reflect and summarize before and after class. In classroom teaching, students are encouraged to explore and cooperate independently. Students learn autonomous learning, cooperative learning and research-based learning in the learning process. Students master these methods and stick to them for a long time to form good learning quality and study habits. If you develop good study habits, you will benefit for life, which is half the success in learning.
Second, use multimedia to stimulate interest in learning.
Interest is the introduction of knowledge. Piaget, a famous Swiss educator, said: "All mental work depends on interest." When one is interested in something, he will pursue it and explore it with fascination. Once a student is interested in learning, it will become his inner motivation for learning. The development of multimedia reflects the development demand of modern educational technology, and optimizing teaching environment is an important guiding ideology in the development theory of modern educational technology. Multimedia means should be fully utilized and optimized in teaching.
When teaching the perimeter of rectangles and squares, I used multimedia courseware to play the courseware "Tortoise and Rabbit Race" at the beginning of the class. The tortoise runs around a rectangular flower bed with a length of 5 cm and a width of 3 cm, and the rabbit runs around a square flower bed with a side length of 4 cm. They reached the finish line at the same time. Please help them find out who ran the long-distance race. The problem is to find the perimeter of a rectangle and a square.
The use of multimedia in this lesson enables students to understand the concept of perimeter, help students to analyze and understand the calculation methods of rectangle and square perimeter, stimulate students' interest in learning new knowledge, learn mathematics in a pleasant and harmonious atmosphere, and cultivate students' problem-solving ability and mathematical thinking.
Thirdly, through knowledge transfer, we can communicate the connection between old and new knowledge and cultivate students' ability to answer math questions flexibly.
Primary school mathematics is a multi-level and multi-faceted knowledge system. Applying the law of knowledge transfer will help students learn new knowledge and solve new problems. To do this, teachers must study textbooks deeply, communicate the relationship between old and new knowledge, classify knowledge, make it beneficial to knowledge transfer, and cultivate students' ability to solve problems flexibly by using knowledge.
For example, when teaching trapezoidal area, I ask students to use the trapezoid in their hands, cooperate in groups, and use the connection between old and new knowledge to find solutions. At this time, students actively use operation experiments, independent exploration, cooperation and exchange activities to explore the calculation method of trapezoidal area. Finally, the group used the transfer of knowledge in the exploration and cooperation to get different methods to find the trapezoidal area, which is definitely more memorable than the formula explained by the teacher.
The construction of this mathematics teaching model scientifically embodies the characteristics of primary school mathematics and children's cognitive law. In teaching, let students rely on old knowledge and master new knowledge through "transfer" and "transformation", which fully cultivates students' ability to acquire knowledge independently, develops students' thinking ability and comprehensively improves students' mathematical quality.
Fourth, strengthen students' hands-on operation ability.
Primary school students can't learn mathematics without specific practical activities. Paying attention to students' hands-on operation is one of the most effective ways to develop students' thinking and cultivate their mathematical ability.
After learning the area of a circle, I did such an exercise for the students. The side length of an equilateral triangle is1.5cm. Now I roll this triangle ABC along a straight line to find the distance length of point A (as shown in the figure). Looking at the students' puzzled expression, I said the word "hands-on operation", and the students cut out an equilateral triangle one after another and began to operate according to the requirements of the topic.
This kind of hands-on practice makes this difficult problem difficult, turns abstract into concrete, further develops students' ideas, and embodies the educational concept of "learning by doing" and "learning by doing", thus making quality education truly implemented.
Fifth, use a variety of mathematics learning methods to fully mobilize students' learning enthusiasm.
According to the characteristics of primary school students' physical and mental development, it is an effective means to stimulate students' learning enthusiasm. Pupils can often study harder under competition conditions than under normal conditions, and the learning effect is more obvious. In the competition, driven by strong competitiveness and curiosity, they always want to win the first place and always want to be praised by their teachers. We can use this psychology to greatly improve students' interest in learning and their perseverance in overcoming difficulties. In teaching, I often organize various competitions, such as "who is faster and who is right" and "which group of stars is more" when learning elementary arithmetic, and "who has more solutions", "smarter than who" and "which group of people is more" when learning combined graphics, which can make students "bigger". Let every student succeed at all levels, let every student experience the pleasure of learning success, so that the incentives for primary school students will be greater and the enthusiasm for participating in learning will be higher.
Sixth, strengthen the guidance of students with learning difficulties and improve the overall level through transformation.
In teaching, if we want to improve the teaching quality, we can't ignore the education of students with learning difficulties. The reasons for their backwardness are different, and teachers need to strengthen individual guidance and teach students in accordance with their aptitude in order to receive better teaching results. I found that some students were not very successful in math learning during the tutorial, but in other subjects.
