Teacher Wu Zhengxian introduced the topic we discussed with an interesting little video: changing the way of learning and promoting deep learning. She believes that the reform of primary school mathematics must adhere to the position of children and carry out teaching activities on the premise of protecting children's growth interests. Let children feel the charm, value and strength of mathematics in their whole-hearted study. Arouse children's interest, confidence and positive emotional experience, so as to love math learning more. In line with the general direction of persisting in children's position, changing learning methods and promoting deep learning, several teachers brought us wonderful math classes.
Teacher Sun Yingxin's topic is Unit 4, Volume 2, Grade 3, People's Education Press: Two-digit Multiplying Two-digit Non-carry Calculation. In teaching, Mr. Sun takes Tao Te Ching as the beginning and end of the whole class, which is permeated with the development of multiplication calculation in a certain order and law. In teaching, Mr. Sun uses various resources to lead students to think about the past and the present, understand the development of computing in China, and feel the simplicity and profoundness of traditional culture. In order to make students understand the meaning of the algorithm, Mr. Sun created a realistic situation by delivering materials during the epidemic and asked questions with doubts. Pass "Is it enough?" Students are encouraged to exchange ideas, explore and solve problems independently, and realize that learning double digits is the practical need to solve problems. This situation runs through. In this lesson, the teacher links the concept of position with the result of each step of vertical multiplication, and makes it clear what counts first, what counts now and what counts last. In addition, with the help of multimedia video, Mr. Sun demonstrated the process of students' separation and integration when they were confused, which made the method clear and helped students communicate the connection between old and new knowledge. At the same time, let students explore by themselves in teaching and cultivate their problem-solving ability and application ability.
Teacher Tang's topic is "Understanding Cuboid", which is a very "fun" class. Teachers use humorous teaching designs to make students feel "the fun of mathematics". The whole class focuses on four activities, one is "guessing", which hooks students' desire for knowledge, and the other is "cutting", which cuts intuitive carrots into cubes, implements the concepts of faces, edges and vertices, and designs boldly and innovatively to make students intuitive and easy to understand. A word "find" guides students to infer the characteristics of a cuboid on the basis of a cube. The last word "doing" provides students with interesting learning tools. Through kneading and building, students can create cuboids and cubes independently, and combine learning with application, so that students can experience the process of knowledge formation and let mathematical knowledge take root. ?
Teacher Xu Yi teaches "statistical charts of broken lines". This course is based on the anti-epidemic situation in Wuhan, with the number of medical staff rushing to Wuhan from all over the country as the starting point to start teaching, so that data can be transmitted to educate people and penetrate the subject value goal of Lide Shu Ren. Xu teacher designed hierarchical homework in teaching, which made the homework list close to the learning situation. He let the students do it through the hierarchical and classified homework list, let the students cooperate in groups on the basis of independent thinking, discuss and communicate, and do it by hand, so that the teaching can be connected with the students' starting point. In addition, xu teacher attaches great importance to students' data analysis ability. In this lesson, students can draw broken-line statistical charts and bar charts by arranging homework sheets. In drawing, they collect data, understand the characteristics of broken-line statistical charts, understand the drawing steps, and combine drawing with reading charts, so that students can deeply understand broken-line statistical charts. Cultivate students' ability to sort out materials, read materials and analyze data in detail, so that their thinking and literacy can grow.
In this study, the profound teaching skills, exquisite teaching skills and advanced educational concepts of famous teachers are amazing. We are very grateful to the famous teachers for bringing us these lessons, and we will also observe and learn from them in the following time.
