化学是一门以实验为基础的科学。实验教学可以激发学生学习化学的兴趣,帮助学生形成化学概念。获得化学知识和实验技能,培养实验操作能力。实验改进能增强实验的直观性,我校条件有限,装配的实验装置不尽合理,又由于个别实验步骤繁琐、操作困难等原因,导致耗时长、实验现象不明显、成功率不高,一定程度上影响了课堂教学效果。我通过反复实验研究,对九年级化学中部分实验提出个人改进建议,旨在激发学生实验兴趣、增强教学效果,提高学生的创新意识、发展学生的探究能力。
Chemistry is an experiment-based science. Experimental teaching can stimulate students’ interest in learning chemistry and help students form the concept of chemistry. Acquire chemical knowledge and experimental skills to develop experimental operational capabilities. The experimental improvement can enhance the intuitiveness of the experiment, the conditions of our school are limited, the assembly of the experimental device is not reasonable, and due to the cumbersome individual procedures, operational difficulties and other reasons, resulting in long time-consuming, experimental phenomena is not obvious, the success rate is not high, to a certain extent Affected the classroom teaching effect. Through repeated experimental research, I proposed personal improvement suggestions for some experiments in the ninth-grade chemistry, aiming at inspiring students’ experimental interest, enhancing teaching effects, enhancing students’ sense of innovation, and developing students’ exploration capabilities.
