化学是一门以实验为基础的自然学科,化学实验教学是化学教学中最全面、最有效的教学形式之一。作为化学学科的重要基础,化学实验是学生学习化学的重要工具,在化学实验的过程中融合了许多科学方法,科学思想。一、演示实验操作规范高中学生的模仿能力很强,老师的言行举止时刻影响着自己的学生。作为一名化学老师。我们上课特别是演示实验时的一点一滴学生都会铭记在心。以前我们对一些危险性比较大的实验,如溴与苯反应制取溴苯的实验、稀释浓硫酸的实验等,不敢做,也怕伤及学生和自己,其实做过之后会发现只要我们操作规范,是不会有危险的。若老师对这些实验存有惧怕心理,那让我们的学生 Chemistry is an experiment-based natural science. Chemistry experiment teaching is one of the most comprehensive and effective teaching forms in chemistry teaching. As an important foundation of chemistry, chemistry experiment is an important tool for students to learn chemistry, which integrates many scientific methods and scientific ideas in the process of chemical experiment. First, demonstrate experimental practices High imitation ability of high school students, teacher’s demeanor moment affects his students. As a chemistry teacher. Students in our classes, especially in demonstration experiments, are always mindful. In the past, we had some dangerous experiments such as the reaction of bromine with benzene to produce bromobenzene experiment, the experiment of diluting concentrated sulfuric acid and so on. We dare not to do it and we are afraid of hurting the students and ourselves. In fact, we found that as long as we Operational norms are not dangerous. If the teacher is afraid of these experiments, let our students
