"When learning mathematics, the teacher often teaches the steps first, and then the students recite them. But if you forget a link, the child will feel that it is over! Lin Lingyi, a math teacher at Heshun Junior High School in Tainan City, said that she took out a Yangchun magnifying ruler from a bag full of teaching AIDS. A closer look shows that the ruler is actually made of readily available materials such as cotton swabs, toothpicks and straws!
"Every year, children are different, but according to different children, the process of learning methods is very interesting! This is why I like teaching. " She said with emotion.
Lin Lingyi has been teaching for 20 years. Since four years ago, she is not only a teacher of students, but also a "living textbook" for teachers. She has a low-key personality and is not eager for success, but she is eager to let more math classes shine with the light of learning. Encouraged by Peng Fujian, the convener of Mathematics Cafe, Lin Ling Friendship stood in the front line, generously shared the curriculum design and implementation for mathematics teachers in the "N Forces of Dreams" community, and gave more front-line teachers from all over Taiwan Province Province support and feedback.
"The first task is not to teach, but to help students overcome psychological pressure. Lin Lingyi said that mathematics is more difficult to understand by reciting or self-study than other subjects. " As soon as the math teacher enters the classroom, he must first face the students' dislike of the subject. 」
In the process of interacting with students, she found that "it's not that students don't want to learn, but that they are willing but unable." She said that the reason why many children are afraid of learning mathematics is not that it is too difficult to learn, but that they are repeatedly frustrated and can't get immediate help in the process of learning. "When they fell down several times and couldn't stand up, frustration came. 」
"Some children can't write and simply don't hand in their homework. However, if you don't have a thorough understanding, you may only see that he didn't hand in his homework, but didn't see the difficulties behind the child. Lin Lingyi shared the learning situation of her classmates. Instead of punishment, she took the student and accompanied him to do the topic during lunch break.
She observed, "When I was with him, he would write, but he didn't do well in the exam. Later, my Chinese teacher and I worked together to find out the problem, only to find that the students didn't understand mathematics, but they didn't understand the meaning of the test paper at all. If Lin Lingyi didn't want to spend time to understand the students' situation and find out the problems from the beginning, she might not know that students actually have dyslexia, not math.
"Companionship" is simple, but it is not easy. Lin Lingyi, like a shepherd, doesn't want any lamb to run away on the way to school. In her eyes, no child gave up studying at the beginning. "If you watch a baby learn to walk, when you fall, you will find a way to stand up again. 」
Stay with the students who are behind in their studies and find out the crux of the problem. Lin Lingyi made students stop avoiding studying mathematics because of setbacks. Provided by Lin Lingyi.
Let students realize that mathematics is the reason why she likes teaching in daily life. "Students don't know why they want to learn. Mathematics is far from life and has many abstract concepts. This was one of the opportunities for Lin Lingyi to change classroom teaching at that time. " I began to think, what can mathematics be combined with? "What new tricks can it conjure up? 」
Being exposed to new things can keep teaching fresh. There was a reading craze a few years ago. Lin Lingyi began to find a lot of popular science books, packed blunt knowledge with interesting stories, communicated with students through study lists, and learned more about children's learning state and attitude under different teaching methods. "I like to constantly give children new things, so that they feel that learning is innovative and will not be bored. 」
At that time, Tainan Nanying Commercial Advertising Design Section held a graduation exhibition, and Lin Lingyi gained a lot during the visit. "There is a three-dimensional graphic unit in the third grade, and I will take my children to do gift design. It was the first time that I integrated the concept of design into teaching. She built a bridge with mathematical concepts in life to help children find the meaning of learning.
"For example, eight-treasure porridge, how do we package and find what materials? What will be cheaper? This needs to take into account the concepts of cost and marketing. Lin Lingyi asked the children to learn while doing, connecting the knowledge in different fields, so that mathematics could no longer escape from the children's heads.
Before long, she took out many cookie boxes that can be seen in shops. "You see, this is a parallel line with the same angle. After Lin Lingyi's explanation, ordinary cartons have become a right-hand man to explain abstract concepts.
Perhaps it is her unremitting enthusiasm for teaching that makes her willing to spend a lot of time making various teaching AIDS. Is it worth the trouble? "Seeing that children never attend meetings, the sense of accomplishment and the way their faces are suddenly enlightened are the biggest motivation for my teaching. Lin Lingyi recalled.
With simple cardboard and cotton thread, the mathematical formula r = a( 1-sinθ) of Descartes' heartline can be turned into a unique Mother's Day card. Provided by Lin Lingyi.
"There is a child in the class who is not good at math, but I found that he is a child who can operate. All hands-on housekeeping and scouts can perform well! In the past teaching career, she found that many children did not do well in exams. Therefore, Lin Lingyi used a more meta-evaluation method to let each child's specialties be seen. " When you provide more materials for children to play with, you can see more yuan. "Some children are good at oral expression, some are good at painting, and some are group coordination. 」
Ready-made board games, after clever thinking, can also become teaching AIDS in the classroom. In this game, you need to observe your opponent before you can work out your strategy. Seeing the mathematical concepts inside, Lin Lingyi adapted and made a board game called "Counting Numbers" to make the students have fun.
"You see, he is also counting in the process of playing, counting the roots at least 20 times. She immediately took out some simple coins, cards and maps and played a board game. In fact, she was thinking about the operation of the root sign. Stimulating strategic thinking through children's competitiveness in playing games, she said with a smile, "If you can successfully solve the task in the game, it means that he has learned something, which is also an evaluation method. 」
For students with different levels in the same class, Lin Lingyi encourages children not to be afraid to ask their classmates. "This is what we often say. Let your children know that you are capable, and you can also teach others when they need you. Because in fact, when you tell others, you are also sorting out your own thoughts. 」
In addition, Lin Lingyi will adjust different teaching methods because of different class levels. "In the grouping mechanism, self-taught students can learn a good' A coffee' and he must bring a poor' C coffee' to complete the task. Coffee A can only get 1 point, and coffee C can get 3 points. Encourage capable students to teach other students who don't learn so fast through mechanism setting. " That is the most important value of a capable person. 」
During the conversation, Lin Lingyi revealed that she was not always an amiable teacher in front of students. But in the process of sharing how each child should teach, she has no impatience in her eyes, but sincerely hopes that every child in the classroom can grow into what she likes.
"What's the use of learning mathematics? A student's complaint prompted Lin Lingyi to get up and change clothes. With readily available materials, she enables students to achieve middle school, stop falling into the cycle of rote memorization, understand points and lines in life, and have mathematics everywhere.
Establish a game-based assessment, so that students can have more ways to evaluate their abilities outside the exam and affirm the value of each child in different aspects. Provided by Lin Lingyi.
