Reflections on the teaching of the law of discovery in the second volume of mathematics in the first grade of primary school
"Looking for the Law" is the content of the second volume of primary school mathematics in Hebei Education Publishing House, which mainly teaches students mathematical thinking methods. This lesson is the first lesson in the unit of "discovering laws", in order to let students feel the universality of life application and at the same time let them be influenced by beauty. This course is taught by independent thinking, cooperative inquiry and group communication. Its greatest feature, I think, is to let students experience the process of "re-creation" in mathematics learning, which is embodied in the following aspects: 1. Provide reasonable materials for students to "recreate" in "learning". The Standard points out: "The contents of students' mathematics learning should be realistic, meaningful and challenging, and these contents should be conducive to students' active observation, experiment, guess, verification and verification. Organize students to guess, which is the beginning of students' participation in mathematics learning activities in this class. Then, on the basis of fully understanding and trusting students, the teachers carry out original design, so that "disks and triangles" become the material for students to "re-create". Second, encourage independent exploration, so that students can "recreate" the children's wisdom at their fingertips in doing. In teaching, teachers attach great importance to students' direct experience, and try their best to design mathematics teaching into tangible practical activities, so that students can do middle school mathematics just like learning to swim in a swimming pool. In class, the teacher gave 10 (4 triangles and 6 circles) to let students rearrange so many methods without adding or subtracting numbers. What a personalized creation! To the students' surprise, they are also "researchers, discoverers and explorers"! Thirdly, it is the starting point and destination of mathematics learning to advocate practical application, let students realize "re-creation" in "use", integrate mathematics experience into life and use mathematics knowledge to solve life problems. In teaching, after students explore various laws, they give examples of regular things in life and appreciate regular pictures, all of which are based on students' life experience and follow the law of coming back from life, so that students can learn, understand and develop mathematics in the process of studying realistic phenomena and appreciate the infinite charm of mathematics. In this class, I integrated with my classmates and successfully completed the teaching task. However, there are also some shortcomings. Because there are many content arrangements, some links are hasty, which reduces the number of students' answers. In short, in the whole teaching activities, happy moments ripple in the classroom, and innovation, independent inquiry, teacher-student interaction and student-student interaction become the main theme of the classroom. In the future, I will continue to learn new courses and new ideas to improve my teaching level.
