"Hey! Here is Mathematics - Mathematical Application of Mathematical Culture" is a direction that the mathematics group of Hanyu Primary School has been conducting classroom teaching research, but under the epidemic, online teaching is uninvited, and educational reform is unexpected. We must take advantage of this opportunity to transform the challenge into an opportunity for teachers and students to grow together, design teaching from a child's point of view, and let online teaching inspire students to love mathematics and feel in learning - there is mathematics here! With this belief, I have taught and researched with teachers in the group many times to explore a good way to teach online.
First, send mathematical knowledge to the interest
Whether it's an indoor classroom or online teaching. Academic analysis is an indispensable part of our teaching process. Students in the lower grades have weak comprehension and logical thinking skills, and their awareness of independent learning is not strong, and it is not easy to maintain a high degree of concentration during online classes. Therefore, we attach great importance to the interesting teaching of the curriculum, send mathematical knowledge to interest, abandon the prejudice of the public "how can picture books be related to mathematics", look for mathematical knowledge in picture books, link the teaching requirements in textbooks, boldly integrate picture books and teaching materials, and realize the infiltration of implicit mathematical culture and the acquisition of explicit mathematical skills.
For example, in the lesson of "Classification and Sorting", the story situation of the picture book "Grandma's Button Treasure Box" is borrowed to stimulate students' desire to classify; Later, the story was adapted, and the buttons were classified from different criteria of shape and number of buttons, and the difficulty was gradually increased, and the slope was taught. In the lesson "Finding the Rules", the picture book story "In Search of the Lost Jewel Crown" is introduced to help the museum curator solve the problems left by the chimpanzee monsters as a guide, and to transform mathematical problems into storylines to help students learn to find the rules. The seamless teaching design is popular with children. The unique interest of picture books not only ensures students' interest in learning, but also enhances the solidity of knowledge acquisition.
Second, send mathematical exercises to the game
In order to avoid online courses from becoming a "full classroom" for teachers to talk about themselves, and strive to enhance students' sense of participation, we combine the content of mathematical exercises with the game of breaking through to enhance the sense of substitution of online teaching. In the practice class of the unit of "Find the Law", the game string with the theme of "Finding the Law Carnival" is designed, and the boring practice questions are transformed into interesting games such as "graphic change change", "digital solitaire", "discerning mistakes", etc., making full use of the game as a medium of online teaching interactive inquiry, improving students' desire to "press the pause button" independently, enhancing the interaction between teachers and students, and improving the quality of online practice classes. On this basis, echoing the classroom, bridging the classroom, in the daily practice content of students, we cleverly add mathematical puzzle games, such as: smart matchsticks, tangrams, cup dance, etc., to maximize students' interest in learning mathematics.
Third, send mathematics to PBL learning
In order to effectively mobilize the learning enthusiasm of remote students, teachers need to design more "student-centered" driven tasks to delegate to students practice, feedback and thinking, and cultivate their self-directed learning skills and habits.
After the completion of the unit "Classification and Sorting", the knowledge is connected with life, and a series of tasks for family storage and organization are designed. The content is as follows:
Such a "project-based" learning task is a very interesting task for students, combining life and learning, and truly achieving "life is mathematics education".
At the beginning of "suspension of classes and non-stop learning", we let students conduct statistics on epidemic data every day, so that they can learn to take data as an observation point, observe the epidemic with a mathematical eye, and through statistical analysis of data, have a deeper and more rational understanding of the number of confirmed cases of new coronavirus pneumonia, the number of people cured and other related knowledge. Students analyze data, ask questions, solve problems, and learn to make preliminary predictions based on the data they record. This assignment will be an unforgettable activity for children who are experiencing the epidemic as they grow up.
Fourth, send mathematical ability to mengwa anchor
"Show the big stage, I'll broadcast it today." Hello everyone, I am the little tutor of today's lecture. "This childish voice, this skillful way of lecturing, simply can't lose the teacher who has worked hard for ten years!" A group of cute babies also found a new identity "small anchor" for themselves in this special time, don't look at them as small, but take on the task meticulously and look like it. When they first contact the anchor of the lecture, they must complete the lesson preparation independently, find the rules of the exercises, summarize the methods of doing the questions, and also arrange the recording scenes and guide the shooting level of the parents and mothers, which is only the initial stage, after the prototype of the lecture appears, they have to accept the teacher's online fine guidance, repeatedly temper the language, until the final wonderful presentation. The "Little Anchor Training Camp" project not only experienced the minds and endurance of the little cute babies, but also greatly improved their mathematical ability. Dare to ask Meng Wa "online class infatuation" a little deeper, three thousand years of laughter and calm.
There is no podium, but there is also educational space; It's hard to hold chalk, but hold the mouse to sweep the clouds! In the era of education 4.0, we are just as Austrian to give!
