一、研究背景随着新课程改革的不断实施,化学课程教学活动形式逐步在发生变化,改掉以前的讲授为主,向着多样化的方向发展.现在的化学教学改革主要是走向学生实验.但是有很多学校根本不能很好地开展化学实验,不少的实验主要由教师画和讲、学生记和背.为了解决现行高中化学课堂教学中的实验误区,可以引入微型化学实验.微型化学实验具备两个突出的特征:一是化学实验仪器微型化.二是实验中试剂用量少,现象明显、节省经费和时间、减少污染、方便携带.
First, the research background With the continuous implementation of the new curriculum reform, chemical education activities in the form of gradual changes in the curriculum, to change the previous lecture-based, to diversify the direction of the current chemistry teaching reform is mainly to student experiments, but There are many schools that can not carry out chemical experiments well, many of which are mainly drawn and taught by teachers. In order to solve the experimental errors in current high school chemistry classroom teaching, micro-chemistry experiments can be introduced. Two outstanding features: First, miniaturization of chemical laboratory equipment Second, the experiment reagent consumption is small, the phenomenon is obvious, save money and time, reduce pollution, easy to carry.
