In the teaching process, because the concept of perimeter is students' first contact, in order to better help students understand its meaning, I created a demonstration of the situation of "little ants crawling around the edge of leaves", which is students' initial feeling and experience of the perimeter of objects, which stimulated students' desire for learning, and then created an activity that allowed students to draw the edges of graphics by hand, and let them point up and down, deepen their understanding of the edges and highlight the edges. Then let the students find and touch the perimeter of the surface of the surrounding objects, and let the students connect the abstract concept of perimeter with concrete examples in life, and feel and get the concept of perimeter by themselves through a series of activities. After revealing the concept of perimeter, by measuring the perimeter of a simple figure, the perimeter is finally calculated, so that students can seek the best way to solve problems through communication. By letting students experience "
Take a look, touch, draw a picture, find, measure, compare and so on, mainly to deepen students' understanding of the circle.
In this lesson, I focused on understanding the meaning of perimeter, and I didn't grasp the time well. It took me a lot of time to know the perimeter, so I was a little anxious when calculating the perimeter of the plane figure, so I used "Are the perimeters of the two figures the same?" This challenging topic did not create a tense learning atmosphere, nor did it pay attention to throwing out the ingenuity of this question. Instead, it focuses on students' speeches, fails to teach children how to think when doing such things, fails to challenge all children's thinking, fails to leave enough time for students to think, and students fail to calm down and think. Instead, I casually responded to the speeches of individual students and went with the flow. Thus, it did not arouse children's desire to learn, resulting in the failure to implement knowledge points and unable to adjust students' emotional fluctuations. In this way, students will form the habit of being lazy to think for a long time. Therefore, when encountering problems in the future, we must give students enough time to think, pay attention to every child, implement every child, make the most in-place evaluation and encouragement for students' wonderful speeches, be open and clear, and let every child learn to think, not to wave his hand prematurely.
Today, I was very fortunate to hear President Nie's guidance and valuable suggestions from teachers, which left a deep impression on me. I feel that there are still many problems worthy of improvement in the classroom, and point out the direction of future efforts. Through careful guidance and comments on this class, I understand that in the future classroom teaching, to create interesting problem situations, we should not only adjust the classroom with interesting games, activities and tasks, but also play a key role in organizing the classroom. The language fluctuates. What links in the classroom need students to be nervous and what links need students to calm down and think, which is also the part I need to think deeply. How to better grasp this degree? This requires teachers to improve their own quality in all aspects and carry out diversified teaching. Therefore, in the future teaching, in order to make the classroom full of harmony, we must guide students to actively think and explore, don't occupy the whole classroom, keep talking, and sometimes we need to teach in a low voice, so that students don't answer questions collectively before answering them, leaving students with time and space for question awareness (if you talk too much, you will lose you), avoiding strangling the thinking space of underachievers, and not treating students as containers carrying knowledge; There should be interaction between teachers and students, between students and students, waiting for every answer from students with expectation, paying attention to every bright spot of students with appreciation, and sharing every success of students with joy.
In short, pre-class analysis, reading textbooks and reading students are the key. Knowing your own shortcomings will point out the direction for future study and teaching. As long as we work hard in this direction, we will certainly be able to do it well and do it better.
