课堂教学是教师活动的主阵地,是学生学习科学文化知识的主渠道。教师做好预习,了解学生,熟悉教材,有助于师生之间和生生之间的良好沟通,是提高数学课堂教学质量的关键环节。讲练结合,精讲多练,营造动手实践、自主探究与合作交流的氛围,构建以学生为中心的数学课堂教学活动,是课堂教学成功的核心所在。 Classroom teaching is the main front of teachers’ activities and the main channel for students to learn scientific and cultural knowledge. Teachers do a good job of pre-learning, understanding of students, familiar with teaching materials, and help students and students to communicate well between life and life, is to improve the quality of mathematics classroom teaching a key link. It is the core of the success of classroom teaching to construct a student-centered math classroom teaching by combining teaching, practicing, practicing, practicing, exploring and cooperating with each other.
