氧化还原反应是高一化学的重点和难点 ,新生若能准确理解并熟练掌握 ,将为以后学习有关配平、计算奠定良好的基础。也将对激发学习兴趣、开创良好的化学学习氛围具有重要意义 ,因此 ,如何引导高一新生主动参与教学过程 ,尽快抓住重点、突破难点、解决疑点 ,将是每位化学教师关 The redox reaction is the key and difficult point of the chemistry. If the freshmen can accurately understand and master the knowledge, they will lay a good foundation for further study on the balancing and calculation. It will also be of great significance to stimulate interest in learning and create a good atmosphere for chemistry learning. Therefore, how to guide the freshmen to actively participate in the teaching process, grasp key points as soon as possible, break through difficulties, and solve doubtful points, will be for each chemistry teacher.
