俄国著名教育家乌申斯基说:“比较是一切理解和思维的基础,我们正是通过比较来了解世界上的一切。”在教学过程中,教师依据教材的特点、学生的认知发展水平和已有的生活经验,单纯地去讲解,往往不能给学生留下较为深刻的印象。而运用“比较”策略,帮助学生找准知识的相同点和不同点,可以帮助学生分清概念,获得规律性的认识,取得较好的效果。 Ussinsky, a famous Russian educator, said: “Comparing is the basis of all comprehension and thinking. It is through comparison that we understand everything in the world.” In the teaching process, teachers rely on the characteristics of textbooks and students’ perceptions The level of development and existing life experience, simply to explain, often can not give students a more profound impression. The use of “comparison ” strategy to help students identify the same point and different points of knowledge, can help students distinguish between concepts, access to regularity and achieve better results.
