数学教学,要从学生的经验和已有知识出发,设计有助于学生自主学习、合作交流的活动,使学生通过观察、操作、猜测、交流等活动,获得数学知识,发展思维能力;获得积极的情感体验,感受数学的价值,激发学习兴趣。《数学课程标准》也指出:“数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程。”可见,数学课堂教学是一个动态的、生成性的活动过程,教师要引导学生在各种活动中体验、发现、交流、感悟,从而推动课堂教学的进程。下面谈谈笔者在教学《圆柱的认识》中的一些感受。
Mathematics teaching should start from the students’ experience and existing knowledge, and design activities that help students to learn independently and cooperate with each other to enable students to acquire mathematical knowledge and develop their thinking skills through observation, operation, speculation and exchange activities; obtain positive Emotional experience, feel the value of mathematics, stimulate interest in learning. The standard of mathematics curriculum also points out: “Mathematics teaching is the teaching of mathematics activities, the process of interaction, interaction and common development among teachers, students and students.” Thus, mathematics classroom teaching is a dynamic and generative activity process , Teachers should guide students in various activities to experience, discover, exchange, sentiment, so as to promote the process of classroom teaching.
