化学是以实验为基础的科学。利用化学实验,启发思维,是启发式教学的特点之一。在化学教学中,除充分运用课本规定的演示实验和学生实验以外,还可以由教师根据实际情况自行设计一些简单易行、现象明显、富有思考性的实验来启发学生的积极思维,使他们从实验现象中得到启示,在教师引导下进行思考,通过解决问题获得新知识,并能在观察、思维、作出判断的过程中,促进知识向能力的转化。
Chemistry is an experiment-based science. Using chemistry experiments to inspire thinking is one of the characteristics of heuristic teaching. In chemistry teaching, besides fully utilizing demonstration experiments and student experiments in textbooks, teachers can also design some simple, obvious, and thoughtful experiments based on actual conditions to inspire students’ positive thinking and make them Inspired by the experimental phenomena, we can think under the guidance of teachers, acquire new knowledge by solving problems, and promote the transformation of knowledge into capabilities in the process of observation, thinking, and judgment.
