高中化学学习难点分析和教学策略研究——以化学反应速率和化学平衡模块为例

Analysis of Difficulties and Teaching Strategies in Senior High School Chemistry Learning——Taking Chemical Reaction Rate and Chemical Equilibrium Module as an Example

结合《普通高中化学课程标准(2017版)》的要求,以化学反应速率和化学平衡为例,分析学生在高中学习过程中存在的学习难点问题,例如基本概念理解不清晰,缺乏建构知识体系的能力,信息整合能力不足,缺乏高效的学习方法等问题。并提出重视衔接必修2与选修4对应知识,合理构建思维导图,有效总结解题的规律,注重培养学生的观察能力和实验能力等教学策略。

Combining with the requirements of"General High School Chemistry Curriculum Standard(2017 Edition)",taking the chemical reaction rate and chemical balance as an example,analyze the difficult problems of students existing in the process of high school learning,such as unclear understanding of basic concepts,lack of ability to construct knowledge system,insufficient ability of information integration,lack of efficient learning methods and so on.It also puts forward some teaching strategies,such as pay attention to the corresponding knowledge of connecting compulsory textbooks and elective textbooks,rational construction of mind map,effectively summarize the law of solving problems,and paying attention to cultivating students’observation ability and experimental ability.
