In a hurry, the warm and romantic "52 1" followed. As teachers, although we were not surrounded by flowers and didn't receive any sweet words that day, we were looking forward to the dream feast-Liulin's "good teacher in my hometown" 20 19 primary school mathematics expert guidance activities. If you ask me, this is the heaviest gift given to us by Liulin Education Science and Technology Bureau from afar, and this is a knowledge feast prepared for us by Shanghai Chief Planner Zhiyuan. For educators, the most touching expression of love is to supplement our nutrition and stride forward on the road of chasing dreams.
If different scenery will bring different visual impacts to people, of course, different classes will also present different taste enjoyment, then different training will naturally have different gains and thoughts. Next, I will talk about some experiences:
(A) low-key soaring "high-profile", hidden in the simple "gorgeous"
This is my most pertinent evaluation of Mr. Kang from Miaowan Primary School in this activity. A low-key life and a high-profile job are the realms that many people yearn for. Seemingly inconspicuous, 40 minutes of class is enough to make her a blockbuster. Teacher Kang perfectly interprets the efficient classroom under the background of core literacy in the new era with simple language and true emotions. Her class seems unpretentious and uneventful, just like her calm personality and calm style. However, there is a fiery heart hidden under her gentle appearance. As soon as she entered the classroom, she cordially communicated with the students with body language, conveyed effective dialogue with the students with gentle eyes, and tolerated the children's mistakes in the classroom with a generous mind. Under the guidance of teacher Kang, the children collided with each other in the form of group communication and cooperative inquiry, which enhanced their emotions, aroused the resonance of their hearts and condensed the strength of the team.
It is an eternal truth that form always serves content and mathematics always serves life. In this lesson, Mr. Kang starts with the scales that students are familiar with, and leads to the equivalence relation, which extends from the known to the unknown and naturally to the equation. Through in-depth and step-by-step links, students can fully realize that mathematics comes from life, and life cannot be separated from mathematics' emotional attitude and values.
I can't help but sigh: as a student of Mr. Kang, the children are really happy. What does it mean to take students as the main body, what does it mean to really return the classroom to students, what does it mean to take care of everything, and what does it mean to make each student's personality known? Teacher Kang made the most perfect interpretation with her ordinary classroom interpretation.
The same ingredients will show different tastes through different people. This is the meaning of being expected to be different in the same class.
(B) in the problem of thinking collision, in the collision to stimulate the spark of wisdom.
Xue Ji 'e, a teacher of Liulin Primary School, has been galloping in the classroom with a capable and skillful teaching style. Her problem-based learning runs through the whole class, thus stimulating students' thirst for knowledge. Starting with students' questions, guided by teachers' questions and based on subject questions, students are guided to ask questions with subject value. Through the encouragement of eyes and praise of language, students are encouraged to ask questions, be good at asking questions, ask questions, and let students experience the process of asking questions, solving problems and generating problems. This is undoubtedly an exciting process in which freedom, enthusiasm and wisdom are constantly flowing.
In the whole classroom, my heart was inexplicably moved. A pair of small hands held high, encouraging words, strange questions, and warm applause again and again, let children enjoy the excitement of challenges and the joy of success. This is a process of intense thinking and surging emotions. In Mr. Xue's class, we were lucky enough to witness all this, and at the same time we smelled the faint fragrance of problem-based learning.
(3) From the balance in the eyes to the relationship in the heart, from the definition in the eyes to the meaning in the heart.
If the classroom is compared to a meal, Teacher Fan Hui's class is undoubtedly the most distinctive "nutritious meal". No matter from the color, smell or nutritional value, it is perfect. Teacher Zhang took the children on a pleasant class trip in a relaxed and natural way, eliminating the strangeness between them. I dare not slack off in the active classroom atmosphere. Don't forget to chew and internalize slowly while enjoying. I can't help playing the role of a student throughout the class. Under the guidance of Mr. Zhang, I silently answered all the questions that the students were asked to answer, but I couldn't help but raise my hand several times and made an audio answer. During the whole observation, I didn't have time to worry about my actions, because the whole person had long been firmly attracted by teacher Zhang's applause.
Teacher Zhang's classroom is permeated with a mathematical thought: let teaching move from the definition in the eyes to the meaning in the heart. From the balance in the eyes to the relationship in the heart, to the model in the heart. Teacher Zhang once said: in this structure, let children constantly distinguish which formulas are equations and which are not. Only by more analysis and comparison can mathematics be formed. The essence of mathematics is to find differences in similarity and similarities in differences. From special to general, and then to special, let children's mathematical thinking and literacy continue to improve.
Returning to daily teaching, what we have to do is not only reminisce about the beautiful scenery presented in the classroom, but more importantly, we need to transfer the mathematics culture infiltrated in the classroom to our own classroom. This is the significance of our observation of open classes.
(A return to primitive learning, so that students can win in solving problems.
Jiang Boju, a famous mathematician, once said: If students are not encouraged to ask why and don't give proof, then math class will lose its soul. Teacher Zhang also said many times in the lecture: being good at asking questions is the beginning of our study of mathematics. There is no doubt in my eyes and no reflection in my heart. In mathematics teaching, we can throw away chalk and blackboard, but we must not throw away problems. It can be seen that the generation of problems plays an important role in mathematics classroom teaching.
Teacher Zhang's lecture once made me think about how many such wonderful moments we missed in the usual class. When children ask questions in class, we sometimes answer them in a perfunctory way and end up hastily, for fear that the children's questions will spread and occupy our pre-specified classroom time. When children ask questions that even we can't answer, there are often worse ways to deal with them. We always tell our children with dignity that we will solve this problem after class. As everyone knows, how much regret this result will cause to children, thus dampening their courage and passion to ask questions on their own initiative. Can you give children the opportunity to ask questions boldly and create their own problem-solving space? Only in this way can new problems arise, and only in this way can our classroom inquiry be truly implemented, and our group cooperation will not become a mere formality. At the same time, children's dominant position can be truly reflected, and we can also gain wisdom and high-quality effective classrooms.
In fact, problem-based learning has been initially carried out in our school. Here I want to share some examples that happened in my class. On May 28th, my topic was Unit 6, Book 2, Grade 1 "Picking Apples". The key and difficult point of teaching is to explore the algorithm and optimization of binary addition. When talking about the matters needing attention in the written calculation method, a female classmate couldn't wait to say, teacher, I want to ask a question. I gave her a chance. She stood up and asked, Teacher, why do the same numbers have to be aligned when calculating by hand? To tell you the truth, I was surprised at that time. I didn't expect the child to ask such a question. I'm still trying to figure out how to organize the language to answer her. Unexpectedly, another student couldn't wait to answer loudly: because the same unit can add up. I'm surprised again. This is a first-grade child. I am really touched that she can make such an answer. Unexpectedly, the children threw out a series of questions as soon as this question appeared. Why do you want to start from the unit? Why do you have to enter one into ten after ten? Of course, in the end, the students answered by themselves. Throughout the class, the atmosphere was very active. The children talk a lot, but I say very little, because I have no chance to talk at all.
After class, I was reflecting: if we always presented these ready-made precautions and definitions to children in the past, we don't know how much children can really understand and master. Now, the problem-based learning classroom has solved all the problems. Children can boldly raise their own confusion and then solve it democratically. In the problem-based learning classroom we are carrying out now, you don't have to worry about the lifeless classroom atmosphere at all, let alone the silence. This is the children's home. With the same information, they will ask all kinds of questions, many of which are unexpected. They are really full of wisdom. Moreover, the communication between children is smoother, so the problems raised will soon be solved by peers, and many new problems will also arise. This is the original intention of developing problem-based learning classroom. Children enjoy learning in middle school, and it is easy to achieve class goals through the process and method of "problem-inspired thinking collision". This is a problem-based learning class being developed in Liulin No.1 Primary School. Although we have just started, we have prepared the soil and planted the seeds. We are learning, thinking, doing and harvesting all the way. If you like, let's stand on the fertile soil of Liulin and wait for the future problem-based learning to take root and even blossom and bear fruit.
(2) Where is the value of teachers?
So what is our value as a teacher? If we are like our mother, if the irreplaceability of our major is obviously insufficient, and if our work is understood by everyone, where is the value of our existence? This is a question worthy of our deep thought. After listening to teacher Zhang's lecture, my confused heart suddenly became clear. Yes, no matter how busy you are, don't forget to give yourself a suitable position, so that our road ahead will be full of sunshine.
Reflections on the teaching of concept course.
First of all, as teachers, we should thoroughly understand the teaching materials. Always keep in mind the three principles of teaching, what to teach? How to teach? Why do you teach? To achieve the following goals: teaching should help students learn mathematical thinking, teaching should help students develop their mental level, and teaching should be good at cultivating students' rational spirit.
Secondly, as teachers, we should try to understand students. We should not only learn to judge intuitively whether students really understand the concept, but also intervene in students' communication in time to explore the essence of the concept by providing identification, especially for students with superficial understanding, so as to achieve high efficiency in mathematics classroom.
Finally, as teachers, we should always remember that teachers are the leaders of the classroom and the classroom is the main position of education. Teaching quality is the lifeline of running a school, the main dimension of full-time teachers' professionalism, and teaching efficiency is the main content of teachers' work reputation and social reputation.
We live in a great era of brand-new scientific and technological revolution, a great era of China's development into a powerful country, and a great era of profound changes in education. Great times call for great spirit, and great times breed great education. Let's embrace the dream of educating people with "new era and new ideas", closely focus on the working idea of "Party building leading, five changes and one innovation" put forward by the county party committee and county government, and internalize what we saw, heard, thought and felt in this expert guidance activity into action. Let's write a glorious chapter of Liulin education with rational thinking and emotional feelings.
