Red Net Time News October 1 (correspondent Huang Si) has a specialized knowledge and specialized in research and mechanics. In order to continuously promote teachers' ability to study and polish lessons and improve the professional level of the teaching and research team as a whole, from September 27 to 29, Shangge Primary School held a special classroom teaching competition for "problem solving" in primary school mathematics.
With the "Return to the Issue" coached by teacher Liu Cong, the competition kicked off. Liu Cong pays great attention to students' classroom learning situation, allowing students to understand the essential characteristics of "total problems" through sufficient comparison activities, and thus master methods to solve such problems.
Meilan brought the second grade lesson "Simple Arrangement". Based on the age characteristics of lower grade students, the situation of "decryption code" was created, and the situation was integrated throughout the whole class, which stimulated students' desire to solve problems. After
class, Yan Xieting gave a wonderful lesson example interpretation of the lesson "Simple Arrangement". She explained the efforts made by this lesson in cultivating students' awareness of thinking about problems in an orderly and comprehensive manner from the aspects of selecting situations, cleverly setting up question groups, and developing thinking.
Luo Tao brought "One number is several times the other number". His classroom allows students to go through the entire process of discovering problems, asking questions, analyzing problems, and solving problems, making students truly the main body of the classroom.
Song Min interpreted the lesson example of "One Number Is Several Times of Another Number". She analyzed the comparison of textbooks in various versions, teaching objectives, design intentions, and link appreciation, and believed that raising a problem is often more important than solving a problem. The process of discovering a problem-raising a problem is the process of cultivating students' innovative consciousness.
Ni Simei brought the "Tea Maker Problem" in the first volume of the fourth grade. She used reasonable situations to guide students to extract what preparations needed to make tea with their life experience, activates students' existing life experience, and the doubts and rebuttals among students in the classroom will help students grow in their learning.
Wang Jing interpreted the lesson example on "The Tea Making Issue". She introduced the design intention of this lesson to us through the horizontal and vertical levels, allowing students to experience the search for various strategies to solve life problems from a mathematical perspective and understand the application of operational ideas in life. The last class of
is "Segmented Billing Problems" taught by Tang Xiumei. Teacher Tang used the form of , combined with , to promote students to effectively read and understand problems from shallow to deep, and built a "dual-mode" classroom that integrates "problem solving teaching model" and "segmented billing mathematical model".
Peng Hua interprets the lesson example on "Segmented Billing". Based on experiencing life situations and perceived models, she believes that guiding students to review and reflect on the ideas and methods of solving problems is to gradually form the structure of this type of problem and complete the independent construction of mathematical models.
After the game, teachers Binyun, Liu Haiming and Xie Ying commented on the five classes. The three teachers unanimously agreed that the growth of teachers in the mathematics group is very large and the atmosphere of grinding classes in the lesson preparation group is very strong. During the teaching process, teachers generally pay attention to the students' subjective position and are good at designing rich activities to allow students to fully perceive and practice, thereby improving students' core literacy.
A flower blooms alone is not spring, but a hundred flowers compete for beauty in spring. This class competition has increased the depth of mutual learning and communication between teachers, and has benefited a lot from teachers. Shangge Primary School Mathematics Group has put a lot of effort into cultivating young teachers to grow rapidly. In the subsequent work, the Mathematics Group will not forget its original aspirations, forge ahead, and strive to build an excellent team.
