氧化还原反应是高中化学的核心知识之一,是学生对化学性质与变化规律的认知与应用的重要内容,高考又对氧化还原方程式配平技能的掌握提出了一定的要求。氧化还原反应具有一定的复杂性,且化学方程式的配平过程也具有一定的复杂性,思维跨度大,故学生并不能轻易地掌握氧化还原反应知识。学生主要有教材学习阶段、总复习阶段两个时间段来完成对氧化还原方程式配平技能的掌握。在学生学
Redox reaction is one of the core knowledge of high school chemistry, is an important content of students’ cognition and application of chemical properties and change rules, and the college entrance examination poses certain requirements for grasping the skill of redox equation. Redox reaction has some complexity, and the chemical equation balance process also has some complexity, thinking span, so students can not easily grasp the redox reaction knowledge. Students mainly have textbook learning phase, the general review of the two stages to complete the redox equation grading mastery. Learn from students
