《数学课程标准》在“课程实验建议”中指出,“教师要积极利用各种教学资源,创造性地使用教材,设计适合学生发展的教学过程”。根据这一重要理念对教材进行调整,充实,让教材亮出绚丽的风采,展现出无穷的魅力。一“、布白”:拓宽教材的探究空间,让学生在引导和探索中体验数学“在人的心灵深处,都有一种根深蒂固的需要,就是希望自己是一个发现者、探索者,在儿童的精神世界里,这种需要特别强烈。”因此,要努力挖掘,拓展教材内容的探索空间,让学生在自主探索的“再创造”活动中深刻体验数学。如,研
The standard of mathematics curriculum pointed out in the Experimental Teaching Suggestions of the Course that teachers should make active use of various teaching resources, make creative use of teaching materials and design a teaching process suitable for the development of students. According to this important concept of teaching materials to be adjusted, enrich, so bright brilliance show style, showing infinite charm. “, Cloth white ”: broaden the space for exploration of textbooks, allowing students to experience mathematics in the guidance and exploration “in the depths of the human mind, there is a deep-rooted need is to hope that he is a discoverer, explorer This need is especially strong in children’s spiritual world. ”Therefore, efforts should be made to explore and expand the space for exploring teaching materials so as to enable students to experience mathematics in their own“ re-creation ”activities. For example, research
