实验的选择与改进使化学教学进一步拓展和深化,可培养学生的学习兴趣和创新精神,也是化学学科可持续发展的有效措施.教师应该用自己的智慧和较强的实验能力来改进实验,使教学效果达到最优化.选择合适的实验来演绎内容很关键.在前段时间的一节比赛课中,我通过实验的改进深刻地感受到合理选择实验的重要性,也引发了对如何更好地操作化学实验的思考.一、实验中的反思苏教版化学选修教材“化学反应速率与化学平衡”第一 The selection and improvement of experiments will further expand and deepen chemistry teaching, and will cultivate students’ interest in learning and innovative spirit. It is also an effective measure for the sustainable development of chemistry disciplines. Teachers should use their own wisdom and strong experimental ability to improve experiments, so that The teaching effect is optimized. Selecting the appropriate experiment to deduce the content is critical. In the course of a lesson in the previous period, I experienced the importance of a reasonable choice of experiments through the improvement of the experiment, and also raised the question of how to better Reflections on Operational Chemistry Experiments I.
