On the morning of May, 2065438 12, I heard Mr. Zhang's class again at the scene of the "China Curriculum Reform" public welfare action. Teacher Zhang and 32 students, with a piece of chalk and a blackboard, walked out of the new realm of the relationship between the total distance and part distance of the encounter problem, and walked out of a new height that we never thought of.
? Teacher Zhang's class subverted my cognition of mathematics class, let me see a different world of mathematics, and broadened my narrow educational vision. After listening, I was deeply shocked!
First, wake up.
? The essence of education lies in awakening. Teacher Zhang woke up not only the classroom, but also the students and the sitting teacher. Thirty-two students face a strange teacher. There was no doubt that I was stiff and timid at the meeting of hundreds of people. However, Mr. Zhang seems to have the talent of a crosstalk performer. When he opened his mouth, everyone laughed on stage and off stage. Teacher Zhang's brain teaser is "Why do people go to the vegetable market to buy food?" At first, Zhang Er Monk, a student, was so confused that no one raised his hand. After encouragement, a classmate raised his hand "because he wants to buy food and cook." Teacher Zhang commented, "You are a normal person, but we all know that you should not think normally when doing brain teasers." The students were deeply encouraged and used the trick taught by teacher Zhang, "guess, guess, abnormal thinking."
When students perform various situations that encounter problems, Mr. Zhang takes two classroom observers as two places, allowing students to walk out of all possible situations on the spot. When the students first started walking towards the two teachers, they stopped automatically. Teacher Zhang immediately pointed out that in fact, most of us are used to being framed in a track, but sometimes we will see different scenery outside the border. Inspired by this, the students walked out of various situations and listed seven possible situations when walking in the opposite direction. Accurately express it with line segment diagram, constantly think deeply about the relationship between the total distance and the travel distance of Party A and Party B, and accurately express it with language. In the whole classroom, the students are all small hands, their faces are red and their eyes are shining. At this point, the students woke up.
After 40 minutes of class, there is still only one sentence on the blackboard, "Party A and Party B go in the opposite direction from AB". My inner thoughts and data information have not been presented yet, no problem. It is estimated that it will take some time to solve the problem. When I was still unfinished, the whole class was over! One sentence of information can hold up a class! There is only one sentence of information. In our opinion, is this a problem? No data information, no problem, however, is this just a sentence? Through teacher Zhang's in-depth excavation, horizontal development and students' in-depth thinking, I am sure that children will analyze all kinds of problems in the future, and which one belongs to different situations. This is not just learning a problem, it is clearly "a glimpse of the whole leopard"! Such a classroom is what children really need. Really abandoned the teaching method of flowery boxing and embroidered legs. The children in the whole classroom are learning in happiness, making progress in thinking, and discovering through exploration that it is really entertaining! I can't help thinking that in the future classroom, learning to use one of the knowledge points as a carrier and cultivating students' ability to think deeply is the direction I need to work hard. At this point, the teacher was awakened.
Second, encourage
Judging from my previous teaching experience, the number of students who raise their hands in math class has been declining with the increase of grade. One of the main reasons is that students are worried that they will be laughed at by teachers and other students after making mistakes, lacking a temperature classroom environment, lack of encouragement and tolerance, and their enthusiasm for learning has not been fully ignited.
In teacher Zhang's class, the evaluation language is "Applause, Great!" It has appeared dozens of times. Whenever students express their ideas, Mr. Zhang will say "applause and encouragement" at the first time, taking pains to say it and saying it without hesitation. In the applause of everyone, every student sat down with dignity and pride. Only in a safe language environment can students confirm that they will be recognized whether they are right or wrong, and it is possible to share their ideas. In fact, every child expects to be noticed and affirmed. No matter right or wrong, children can always find praise. A "applause" inspired the students to talk nonsense, and finally so many eloquent students emerged. Even Teacher Zhang said, "Little friend, you have reached a conclusion that mathematicians all over the world have not reached. You are really something. " What a high evaluation!
Third, out of bounds
Teacher Zhang is nicknamed "Mathematical Madman", and one of the meanings of madman is a person with eccentric behavior; Second, people who may make crazy or licentious behaviors. Presumably, the origin of teacher Zhang's nickname is because he often doesn't take the usual path and always makes some unconventional moves.
? This can also be seen in class. For example, at such a grand event, students have the courage to choose to teach fifth-grade knowledge to fourth-grade students. For example, after reading the news that "Party A and Party B start from AB at the same time", the problem is what they can't understand. When the students pointed out the "opposite direction", Teacher Zhang praised them first. "Fourth-grade children learn fifth-grade knowledge. In this sentence, you actually only have "the opposite direction". You are amazing ",and then guide the students to find a way to look it up in the dictionary. The students were very surprised It is said that there is no dictionary in math class. Teacher Zhang's words are even more shocking. "Who said there was no dictionary in math class? My class should bring not only a dictionary, but also an English-Chinese dictionary. " Finally, under the guidance of Mr. Zhang, through Baidu search, students can complete their understanding of "opposite" and complete their own. In addition, Mr. Zhang also teaches students from the perspective of educating people in the context of students demonstrating the problem of meeting. If he does anything in life and dares to go beyond the boundaries, he will find more different scenery and realize the transformation from "teaching children mathematics" to "educating children with mathematics"
? He even broke the outdated traditional thinking of male teachers teaching primary schools. In an official WeChat account, Teacher Zhang once said confidently and domineering that I am not a teacher, but I teach primary school students. Even in the class for first-grade children in Shanghai, there is no sense of disobedience. In this lesson, when Mr. Zhang is full of passion, his words hitting the floor in class, colorful expressions and flexible body language, especially when he finally leads the students to summarize the different situations of this lesson, he swings his left hand and his right hand, full of passion and vitality, immersed in the interaction with students, which probably incorporates dance elements. The "mathematical madman" who doesn't take the usual path ignites the enthusiasm of students and the fire in the teacher's heart.
Teacher Zhang's classroom has a height, depth, temperature, breadth and panoramic view, giving children a panoramic mathematical world. "The mountain is high, and the scenery has stopped. Although I can't get there, I yearn for it. " Because of a course, falling in love with a subject, everything is possible!
