Reflections on the teaching of "how much you know"

In this lesson, I review the introductory questions, and then guide the students to understand the meaning of several points through origami games; Then try to guide students to further understand the score; Then guide the students to compare the scores by comparison, coloring and other methods; Finally, summarize and guide students to learn to summarize knowledge.

In classroom teaching, I give full play to the role of a guide. Through the introduction of origami games, students' interest in learning is stimulated, and students are prompted to find problems, solve problems and understand the meaning of several points. The key is to firmly grasp the breakthrough point of old knowledge and new knowledge, and the "initial understanding of score" must be based on the concept of "average score". Therefore, when I introduce the course, I introduce the old knowledge that children are familiar with. At the beginning of teaching, I asked students to review a few key points first, and then introduced origami games to guide students to understand the meaning of scores in the games, and then consolidated their knowledge through practice.

In the teaching activities of this class, I make full use of modern information technology, which provides cognitive representation for learning new knowledge more intuitively and helps students to be more willing to devote themselves to realistic and exploratory teaching activities. This enables students to experience teaching activities full of exploration and creation, and enables students to succeed in constant exploration. Teachers are both guides and organizers. They handle all the exercises, concentrate on tutoring a few students and leave the summary to the students.

There are still some shortcomings in this course, such as not understanding the intention of compiling teaching materials well, and not grasping the main line-score unit in classroom teaching, which makes it more difficult for students to understand scores. In the future, we must strengthen our study, carefully study teaching materials, study curriculum standards, and carefully design the teaching process. Only in this way can the classroom teaching efficiency and teaching effect be continuously improved.
