对化学的学习与研究必须建立在实验的基础上,自成为化学老师的第一天起,我便笃信这一点。教师的实验基本功及实验教学理念对于培养学生的实验能力至关重要。一、教师首先要形成扎实的演示实验基本功。在新课程改革之前,能够开齐、开全教材中所有的演示实验、分组实验是当时的最高要求。对于教学新手来说,对于某些演示实验的操作还不够熟练,成功的机率不够高。例如做镁带燃烧的实验时,常因酒精灯火焰未调节好,镁带打磨不充 The study and study of chemistry must be based on experiments. From the first day of becoming a chemistry teacher, I firmly believe this. The teachers ’experimental basic skills and experimental teaching ideas are very important for cultivating students’ experimental ability. First, teachers must first form a solid demonstration of experimental basic skills. Before the reform of the new curriculum, we could open all the demonstration experiments in the whole textbook. The group experiment was the highest requirement at that time. For teaching newbies, the operation of some demonstration experiments is not yet proficient, the chance of success is not high enough. For example, do experiments with magnesium burning, often due to alcohol lamp flame is not adjusted, magnesium is not enough polished
