化学是以实验为基础的科学。凡是从事化学工作的,都离不开化学实验。从中学化学教学的特点来看实验教学更为重要,因为中学化学是打好学习化学的基础的,不通过实验现象的观察、分析、综合,就不能获得丰富的直观的感性认识,也就很难上升为理性认识,可见,不做化学实验的教学,是违背认识规律的。在教学实践中,由于认识不足,学校设备、实验条件较差,实验教学困难很大,但我们努力搞好实验教学,已初见成效。这里仅仅谈谈我们的一些做法。
Chemistry is experimental science. Those who are engaged in chemical work, are inseparable from chemical experiments. Experimental teaching is more important from the characteristics of chemistry teaching in middle schools. Because chemistry in middle schools is the basis for learning chemistry, it can not obtain rich and intuitive perceptual knowledge without the observation, analysis and synthesis of experimental phenomena. Difficult to rise to a rational understanding, we can see, do not do chemical experiment teaching, is contrary to the law of cognition. In teaching practice, due to lack of understanding, school equipment, poor experimental conditions, experimental teaching difficult, but we strive to improve experimental teaching, has achieved initial success. Here just talk about some of our practices.
