教学实践告诉我们，影响学生观察能力的因素很多，但究其根源，都与观察者———学生的观察品质即观察的系统性、目的性、准确性、敏锐性等有着直接的关系，也就是说，培养学生良好的观察品质，对于学生获取感性知识，形成学习化学的基本能力，有着极为重要的作用，下面就此谈 Teaching practice tells us that there are many factors that affect students’ observation ability, but the root causes are directly related to the observer’s observation quality, ie the systematicness, purpose, accuracy, and sensitivity of the observations. That is to say, cultivating students’ good observation qualities plays an extremely important role in students’ acquisition of perceptual knowledge and the formation of basic learning chemistry abilities.
