演示实验、分组实验、课外小实验和小制作及一题多解的方法都是培养学生发散思维和创新意识的有效途径。教师在教学过程中不仅要设法多做演示实验，而且还应该创造条件将演示实验生活化、趣味化，在演示实验结束后，把分析过程、实验结果留给学生讨论，并让学生根据实验原理解? Demonstration experiments, grouping experiments, extracurricular experiments and small-scale production and multi-solution methods are all effective ways to cultivate students’ divergent thinking and innovative consciousness. In the teaching process, teachers should not only try to do more demonstration experiments, but also should create conditions to demo the experimental life and make them interesting. After the demonstration experiment is over, the analysis process and experimental results are left to the students to discuss, and the students are allowed to follow the original experimental conditions. understanding?
