部编化学课本,增加了实验数量,提高了实验要求,因此,如何认真贯彻新教学大纲的精神,切实提高实验教学的质量,成了当前值得探讨的一个课题。我们在学习“教学大纲”,熟悉教材的同时,反复学习并明确化学实验的目的与要求。并妥善安排演示实验、并进实验和学生实验。为使实验能达到一定的效果,课前我们都认真作好准备工作。即使对于一般简易的实验,也要检查仪器、药品是否齐全,规格是否正确,装置是否合适。对于少数难度较大的实验,在课前反复预试,找到成功的关键,力求做到课上一次成功。近年来,我们结合准备实 The Department compiled textbooks for chemistry, which increased the number of experiments and raised the experimental requirements. Therefore, how to conscientiously implement the spirit of the new syllabus and effectively improve the quality of experimental teaching has become a subject worthy of discussion. While we are learning the “syllabus” and familiar with the teaching materials, we have repeatedly studied and clarified the purpose and requirements of the chemical experiment. And arrange the demonstration experiment, the progress experiment and the student experiment properly. In order for the experiment to achieve a certain degree of effect, we must all make preparations before the class. Even for simple experiments, check whether the instrument and medicine are complete, whether the specifications are correct, and whether the device is suitable. For a few difficult experiments, try again before class to find the key to success, and strive to achieve success in class. In recent years, we have prepared
