教材是落实课程标准,完成教学计划的重要载体,也是教师进行课堂教学的主要素材和依据。《数学课程标准(实验稿)》明确指出:教师要积极利用各种教学资源,创造性使用教材,设计适合学生发展的教学过程。为此,数学教师必须发挥自己的创造性思维,在新课程标准的指导下,结合教学和学生的实际需要,从整体上准确地把握教材的本质,科学地对教材进行更换、更新、调整和延伸,创造性地使用教材,使教材充满活力。所以作为一个数学教师不应只是被动的执行现有数学教材,而应努力驾驭于课堂之外,对数学教
Teaching materials is to implement the curriculum standards, an important carrier of the completion of the teaching plan, but also the main material and basis for teachers in classroom teaching. “Mathematics curriculum standard (experimental draft)” clearly states: teachers should make full use of various teaching resources, creative use of teaching materials, design suitable for the development of students teaching process. To this end, mathematics teachers must play their own creative thinking, under the guidance of the new curriculum standards, combined with the actual needs of teaching and students, to grasp the essence of the teaching material as a whole, to scientifically replace, update, adjust and extend the teaching materials , Creative use of teaching materials to make teaching materials full of vitality.
