为了让学生更好、更快地掌握知识我决定开展学生自己动手做实验。化学实验能培养学生的观察能力、思维能力、探究能力,通过化学实验的探究中学生可以把化学知识与观察、推理和思维技能结合起来,从而可以能动地获得对化学知识的理解。在实验过程中,学生参与了问题的提出、猜想假设、制定计划、设计实验、探究实验、获得结论和交流评价。教师要充分发挥实验在培养学生创新精神和实践能力方面的作用,让学生带着自己的问题运用实验加以解决,培养实践能力。 In order for students to acquire better and faster knowledge, I decided to carry out experiments by students themselves. Chemistry experiments develop students' ability to observe, think, explore, explore through chemistry experiments Middle school students can combine chemical knowledge with observation, reasoning, and thinking skills to gain an understanding of chemistry. In the course of the experiment, students participated in raising questions, supposing hypotheses, making plans, designing experiments, exploring experiments, getting conclusions and exchanging opinions. Teachers should give full play to the role of experiment in cultivating students' innovative spirit and practical ability, let students use their own problems to solve the problem and cultivate practical ability.
