有比较才有鉴别。比较是确定事物之间共同点与差异点的一种思维方法。在数学教学中,合理和充分运用比较的教学策略,可以丰富学生的认知背景,加大学生认识知识和理解知识的广度和深度,从而更好地掌握知识。一、运用比较策略,深化数学理解数学教学内容的序状展开推动了教学进程。从教学发展态势 There are more discriminating. Comparison is to determine the commonalities and differences between things a way of thinking. In mathematics teaching, reasonable and full use of comparative teaching strategies can enrich students ’cognitive backgrounds, increase students’ knowledge and understanding of breadth and depth of knowledge, and thus better grasp of knowledge. First, the use of comparative strategies to deepen mathematical understanding of the sequence of mathematics teaching content to promote the teaching process. From the teaching development trend
