A good beginning is half the battle. The leading part of the new lecture is like a prelude to a play. If arranged well, you can get twice the result with half the effort. Before importing, teachers should properly handle the relationship between "teaching" and "guiding". The value of teaching lies in guidance.
First, import with old knowledge. The introduction of using old knowledge is based on what students have learned, which leads to new teaching topics, guides students to review old knowledge and learn new ones, and provides a fulcrum to link old and new knowledge from teaching activities such as reviewing, asking questions and doing exercises, and builds a bridge with old knowledge. The successful application of the principle from known to unknown not only consolidates old knowledge, but also paves the way for new knowledge.
Second, the game introduction method. Spencer, a modern educator, said: "Education should make people happy, and all education should be interesting." Games are children's favorite form of activity. According to the lively and curious characteristics of primary school students, in order to embody the new curriculum concept of "classroom teaching should create a relaxed and pleasant learning atmosphere for students", teachers can organize students to play various novel and interesting games or hold some novel competitions when introducing new curriculum, so as to integrate knowledge, interests and ideas and enable students to actively participate in the new curriculum in a relaxed and pleasant teaching atmosphere. For example, to talk about the stability of a triangle, the courseware shows a site map with many tower cranes on it. Teacher: What do you see? (Student answers: I see many tower cranes, and there are many triangles on the tower cranes. Why do you want to design a triangle?
Teacher: The students observe carefully. After learning this lesson, you will know the reason. Today, we will learn "triangle" together. (blackboard writing subject) 2. Explore new knowledge. 1. Understand the stability of triangles. (1) Introduce game to stimulate conflict.
Find a strong boy and a thin girl, take a triangular frame and a parallelogram frame respectively, and then pull to see who pulls first. Most students may think that boys will win, but the result is unexpected, thus stimulating cognitive conflicts and stimulating the desire to explore. )
Teacher: Is this boy really inferior to this girl? There seems to be some mystery in this. Let's study it together.
⑵ Group activity: Nail a figure you like with all kinds of hard paper strips and thumbtacks on the table, and then pull it to see what you find. ⑶ Teacher's summary: The shape of triangle is not easy to change, so we say that triangle has "stability".
Third, error correction and lead-in
In order to let students firmly grasp some easily overlooked knowledge, unrealistic answers are deliberately set to impress students. When teaching decimal addition and subtraction, I introduced it like this: "A classmate is explaining." A classmate spent 49.2 yuan on meat and 5.92 yuan on food in the market. How much did he spend on vegetables? "When solving the problem, the answer is 54.94 yuan, which is the teacher's wrong number. Please look at the mistakes.
Fourth, problem introduction.
Directly use some practical problems in life to solve for students, and then have questions, at this time you can seize the opportunity to import.
This Saturday, Xiaoxiao is going to visit Waixiao. The road map to grandma's house (shown on the blackboard) Which way do you think Xiaoxiao is the shortest? Is this really the case in supermarkets? Are our guesses correct? In this lesson, we will discuss the relationship between the three sides of a triangle. In this lesson, we use mathematical knowledge to solve it.
Five, timely theme import
Directly, directly explain the content to be learned in this lesson. This can introduce simple operations such as decimal addition and subtraction; Students have learned simple operations in integer addition and subtraction. Now let's learn the simple operation in decimal addition and subtraction to see if it is the same as the simple operation in integer addition and subtraction.
Sixth, intuitive import
There are many concepts, properties, laws and formulas in primary school mathematics teaching, and it is often difficult to get good results if we only rely on language narration. People's cognitive process is from perceptual to rational, from intuitive to abstract. For example, teaching with intuitive teaching AIDS, learning tools, objects or audio-visual means is more convincing and vivid than simply commenting and narrating. As the saying goes, seeing is believing. Therefore, providing students with very rich and practical perceptual materials and visually prompting the connection between objective things can make knowledge become boring and vivid, abstract and concrete, and make students concentrate and leave a deep impression. Therefore, the use of intuitive guidance plays an important role in stimulating students' learning motivation and developing new courses. For example, students are only required to recite that the sum of the internal angles of a triangle is 180 degrees, and they can only know why, but not why. If we only describe the process of calculating the sum of internal angles according to the figures and words in the textbook, we will also lack a sense of movement and image, and we will not achieve satisfactory results. Therefore, the tutorial design of this lesson must be verified by hand first. Cut and fold acute triangle, obtuse triangle and right triangle, and see what they find in their three corners. When children find that they are right angles, they are operating, demonstrating and explaining the method of finding the sum of the internal angles of triangles according to the textbook method.
Teaching has the law, but teaching cannot. There is no fixed form for the guidance method of a class, but it has its common form. In a word, there are various skills in classroom teaching. In specific teaching, teachers should choose appropriate methods according to the actual situation to make classroom teaching the most effective.
