一、通过创新演示实验激励学生的创造意识创新演示实验需要创造性地教学。要培养学生的创新精神,教师首先要具有创新精神和创新能力。在实验教学中,教师要勤于思考,勇于探索,做好演示实验的改进工作。如物理课本第一册图11-4“鸡蛋将怎样?为什么?”的演示实验可以这样改进:把广口瓶换成150mL平底烧瓶,把去壳的熟鸡蛋换成去壳的熟鹌鹑蛋,演示时把一端浸过酒精棉的铁丝点燃后迅速插入烧瓶中,待燃烧片刻后抽出铁丝,再迅速将鹌鹑
First, motivate students’ creative consciousness through innovative demonstration experiments. Innovative demonstration experiments require creative teaching. To cultivate students’ innovative spirit, teachers must first have the spirit of innovation and innovation. In experimental teaching, teachers should be diligent in thinking, brave enough to explore, and do a good job of improving the demonstration experiment. For example, in the first volume of Physics Textbook 11-4, “What will the eggs do? Why?” The demonstration experiment can be improved by replacing the wide-mouth bottle with a 150-mL flat-bottomed flask and replacing the shelled cooked egg with a shelled cooked egg. The egg, when it is ignited, is ignited by a wire that is immersed in alcohol cotton at one end and quickly inserted into the flask. After a moment of combustion, the wire is pulled out, and the wire is quickly removed.
