《数学课程标准(2011年版)》指出:“数学教材为学生的数学学习活动提供了学习主题、基本线索和知识结构,是实现数学课程目标、实施数学教学的重要资源。”教材既是教师进行教学的蓝本,又是学生学习知识的依据。因此,在教学中教师要重视学生研读教材能力的培养,加强研读训练,使学生掌握科学的研读方法 The Mathematical Curriculum Standard (2011 Edition) states: “The mathematics textbook provides students with learning topics, basic clues and knowledge structures for their math learning activities, and is an important resource for implementing mathematics curriculum objectives and implementing mathematics teaching.” The textbook is both a teacher The blueprint for teaching, but also the basis for students to learn knowledge. Therefore, in teaching, teachers should pay attention to the cultivation of students’ ability to study textbooks, strengthen their study training and make students master the scientific study methods
