Keywords: primary school mathematics, interest, class companions
Primary school mathematics is a subject with strict logic, which makes people feel very boring to learn. However, mathematics classroom can also arouse the atmosphere of teachers and students, filled with interesting fragrance. Interest in learning is the intrinsic motivation of students' learning, and it is a strong desire to promote students to explore inner truth and acquire ability. It plays a very important role in learning activities. Teaching practice shows that if students are curious about mathematics knowledge and confident in learning mathematics knowledge, they will always study actively and happily. Combined with the current classroom teaching, I want to talk about my personal experience and communicate with you:
First, the new curriculum reform advocates the importance of classroom generation. In the teaching process, students, as effective forces, take part in classroom activities with their knowledge, experience and emotions, which leads to many unexpected situations in the classroom before class. Many of these "accidents" are valuable curriculum resources. For these valuable "accidents", if we perfunctory, ignore or reprimand, the classroom will only become a pool of stagnant water, students'.
As the saying goes, "A good beginning is half the battle". Although the beginning of a class is only a few minutes, it often affects the success or failure of a class. Therefore, teachers must carefully design the lead-in at the beginning of each class according to the teaching content and students' reality, stimulate students' interest in learning with clever lead-in, and let students actively engage in learning. For example, in the introduction of "the sum of internal angles of triangles", I asked students to take out three different triangles (right, acute and obtuse triangles) prepared by themselves, measure the degrees of three angles in each triangle with a protractor, and then asked several students to quote the degrees of two angles of different triangles. I immediately said the degrees of the third angle. At first, some students were still unconvinced and thought it might be a coincidence. I gave several examples and I was right. At this time, the students were surprised at how consistent the teacher's answer was with their measured answer. As a result, the interest in "finding out" arises spontaneously.
Third, learning begins with thinking, and thinking comes from doubt. "Doubt" is the starting point for students to learn mathematics knowledge and start thinking. In mathematics teaching, as a teacher, we should be good at asking questions that arouse students' thinking, make students feel puzzled and interesting, and produce an interesting curiosity and desire for success.
Fourthly, practice is a necessary way to consolidate the knowledge and form skills, and it is also an important environment for teaching. However, boring practice forms and boring practice contents often drown out the interest in learning new knowledge, which seriously stifles and inhibits students' happy mood and inspiring spirit. Therefore, classroom exercises should be designed to be wonderful and interesting, and teachers should design different forms of exercises according to what they have learned.
1, pay attention to the level of practice form.
Design different types and levels of exercises, from the basic exercises of imitation to the suggested variant exercises, and then to the extended thinking exercises, so as to reduce the slope of exercises, take care of students at different levels, and let students always maintain a high enthusiasm for learning.
The classified query of periodical articles is in the periodical database.
For example, in "the sum of angles in a triangle", when solving a problem by using the law, first know two angles to find the third triangle; Knowing one acute angle of a right triangle, find the other angle, and the sum of the two acute angles of a right triangle is 90; Finally, one angle of the triangle is known, and the other two angles are equal. Find the degrees of the other two angles, or if all three angles of a triangle are known to be equal, find the degrees of three angles of a triangle. The above design, through hierarchical practice, constantly sets off the climax of students' cognitive activities, and students are interested in learning and don't feel bored.
2. The practice form should be scientific and interesting.
Bruner said: "The best stimulus for learning is interest in the materials you have learned." In teaching, we can choose some topics that students like, have a little plot and are widely used in students' life experience and daily life. Through a small number of interesting topics and various forms of topics, students become happy to know them. For example, after completing the basic questions in this lesson, ask students to draw a triangle in their notebooks, and ask that both internal angles are right angles. When students can't draw, they all scratch their heads and think hard. At this time, the teacher told the reason why "painting can't come out", and the students suddenly realized.
The first half of a class is the best time for students to receive knowledge, but the attention of students in the second half is easily distracted. At this time, designing some interesting math activities and games can not only give the brain a proper rest, but also attract students' attention and achieve the effect of "interest is still there after class".
At the end of this class, I designed a test question.
Secret: How many ways can you cut off a part of the left figure (only once at a time) so that the sum of the internal angles of the remaining figures is 180? "The students thought that there were only a few cutting methods, and later they learned that there could be countless cutting methods. This is a' great discovery'. But what makes them feel "great discovery" is that although there are countless cutting methods, there is only one figure left, because the figure with the sum of internal angles of 180 can only be a triangle. This practice enables students to experience the joy and happiness of success in exploration.
Six, the "evaluation" here refers to the teacher's oral or written evaluation of students' questions and answers or homework. Mathematical materials themselves are difficult to arouse students' direct interest because of their less emotional color. If the math teacher can be humorous in teaching language, speaking speed, intonation and tone, and give students a little emotional flavor in answering questions and evaluating homework, then students can add fun and enjoy learning in the process of learning math.
For example, in the teaching of this class, when the students found the inner angle and characteristics of the triangle, I immediately praised "you are really capable, you are the first mathematician in our class to discover the truth"; For another example, a student found another way to prove a triangle, and I said to him, "You are so smart." ; When the students finally succeeded in solving the problem, I said "Congratulations, you succeeded" and so on, to stimulate the students' desire for success. In addition, I always use some deep regrets when dealing with students who have difficulties in homework. Such as "What a pity", "Almost", "Good idea, but say ……", "Don't mind saying it again" and "It will definitely be better next time". ..... These words of respect, hope and regret are both emotional compensation and psychological adjustment for poor students, which can make them turn boring into interesting, interesting into interest and interesting into fun in the exploration of learning mathematics.
From the perspective of students' development, the mathematics classroom that can make students feel full of interest in learning is the development of potential, the awakening of spirit and the display of personality. From the life course of teachers and students, it is the enjoyment of experience, the integration of emotions and the appeal of the soul. The scientist Einstein once said, "Love is the best teacher." As a math teacher, we should flexibly adopt various methods in teaching according to different teaching contents and different students' realities, so as to further stimulate students' interest in learning, make students' thinking active, and make students' brains active, thus activating classroom atmosphere and improving classroom teaching effect.
Hope to adopt, thank you! !
