“化学是一门以实验为基础,研究物质的组成、结构、性质及其变化规律的自然科学。”在实际教学中,实验失败的原因是多方面的,教师应该根据不同的失败原因培养学生各种相应能力。一、正视失败,培养敢于承认过失的道德品格在化学教学过程中,教师需要进行无数次的演示实验,有时难免会出现因为教师自身对实验的准备不充分或是操作失误造成实验的失败。如在演示“铁与水蒸气反应”的实验过程中,可能会因为软质试管高温被熔化变形,还可能检验生成氢气时因肥 “Chemistry is a natural science that studies the composition, structure, properties and changes of matter based on experiments.” In actual teaching, there are many reasons for the failure of experiments. Teachers should, according to different reasons of failure Students develop a variety of appropriate ability. First, the face of failure, training moral character to dare to admit fault In chemistry teaching process, teachers need to conduct numerous demonstration experiments, and sometimes inevitably occur because of the teacher’s own preparation for the experiment is not sufficient or the failure of the experiment caused the failure. As demonstrated in the experiment “iron and water vapor reaction,” the high temperature of a soft test tube may be melted and deformed, and it is also possible to check whether the hydrogen
