Understanding the cylindrical model, teaching design and reflection
** I. Teaching Design ** #(I) Teaching objectives 1. To let the students understand the cylinder model, including the names and characteristics of each part, and to establish the concept of the cylinder's geometric model. 2. Through the process of operation and observation, the students 'ability to analyze, reason, and judge will be improved. 3. Cultivate the students 'initiative to explore, develop the concept of space, increase their interest in learning, and establish the confidence to learn mathematics well. #(II) Difficulties in Teaching 1. ** Main point ** - Understand and master the basic features of a cylinder. 2. ** Difficulty ** - To develop the students 'concept of space, so that the students have a deep understanding of the basic characteristics of the cylinder. #(3) Teaching process 1. ** Revise old knowledge, preliminary perception ** - The teacher guided the students to observe the learning tools (cuboids, cubes, columns, cones, balls, etc.) and discussed the classification methods at the same table. Through the classification, the cylinder was introduced, and the cuboid and the cube were compared. The characteristics of the cylinder were discussed, such as the cylinder had a plane but not all planes. 2. ** Know the parts of the cylinder ** - Show the model of the cylinder and let the students observe and point out the bottom (two circles of equal size), the side (curved surface), and so on. By touching the model, one could feel that the bottom was flat and the sides were curved. 3. ** In-depth exploration of cylindrical features ** - Comparing the characteristics of the bottom circle, such as diameter and radius. To explore the relationship between the side and the bottom, for example, if the side of the cylinder was unfolded, it might be possible to get a rectangular shape (cut along the height, the length of the rectangular shape is equal to the circumference of the bottom, and the width is equal to the height of the cylinder) or a quadrilateral (cut diagonally, the base of the quadrilateral is equal to the circumference of the bottom, and the height is equal to the height of the cylinder). 4. ** Practice and Consolidating ** - Give some objects and let the students judge whether they are cylindrical or not, or let the students describe the characteristics of the cylindrical model. ** 2. Reflection on Teaching ** #(I) Strengths 1. Through the review of old knowledge and the classification of learning tools, it could better lead to the study of the cylinder and pave the way for new knowledge. 2. In the teaching process, students should pay attention to observing and touching the cylinder model, which is helpful to intuitively understand the characteristics of each part of the cylinder. 3. The exploration of the side of the cylinder deepened the students 'understanding of the relationship between the side and the bottom of the cylinder. #(2) Inadequacies and improvements 1. In the teaching process, there might be insufficient attention to individual students who understood slowly. In the future, we should strengthen the guidance for students at different levels. 2. It could add more examples that were related to real life, so that students could better understand the wide application of the cylinder in life, thus increasing their interest in learning. 3. The exploration of the characteristics of the cylinder could be more open, encouraging students to discover more characteristics of the cylinder on their own. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
