“对比实验”是将“对比”和“实验”两种认识事物的方法有机结合在一起,通过实验进行对比,或用对比的方法进行实验,便于学生更好地理解、掌握和巩固化学知识。在对“对比实验”的感知、分析和设计等过程中,学生的实验素养能得到大幅度的提高。初三学生刚接触化学,对化学知识的掌握和思维能力的养成正处于启蒙和积累的阶段。因此,在“对比实验”教学中培养学生的思维能力是一个循序渐进的过程。下面以探究学习物质燃烧的条件为例,说明“对比实验”教学中思维 “Contrast experiment ” is a combination of two methods of understanding things, contrast and experiment to compare them by experiment or experiment with contrast to make students understand better, Master and consolidate chemical knowledge. In the process of perceiving, analyzing and designing “contrast experiment ”, the experimental quality of students can be greatly improved. Junior high school students just access to chemistry, grasp of chemical knowledge and thinking ability is in the stage of enlightenment and accumulation. Therefore, cultivating students’ thinking ability in the teaching of “comparative experiment” is a gradual process. The following study to explore the conditions of material combustion, for example, “contrast experiment ” teaching thinking
