氧化还原反应在中学化学的学习中占有重要的地位,是化学学习的重点,而在当前的教学实践中,学生尽管经过较长时间的训练,仍对概念理解模糊不清。笔者结合江苏省如皋市“活动单导学”教学模式的做法,将教学内容设计成一系列的学生活动,取得了有效的成绩。(“活动单导学”教学模式是江苏省如皋市在改革中探讨的教学方法,是教师以活动单为媒介,根据学习目标,把教材的内容、要求以及相关教学资源,设计成几个可操作性、目标性和生成性的活 Redox reactions play an important role in the learning of middle school chemistry and are the focus of chemistry learning. In the current teaching practice, although the students have been trained for a long time, they still have unclear understanding of concepts. Combining with the “active single-study” teaching mode in Rugao, Jiangsu Province, the author designed the teaching content as a series of student activities and achieved effective results.
