高中化学教学中“问题链”的设计与实践探究

Design and Practice Exploration of"Problem Chain"in Senior Middle School Chemistry Teaching

新课标把培养和增强问题意识、发现和提出有探究价值问题的能力、独立探索和质疑能力等设为课程目标,教师应立足学情和章节内容设计和实践“问题链”,让学生在问题的发现、提出、探究、解决中,在物质变化密码破解及感受化学世界神奇的过程中,学习和建构知识体系,培养和提高探究实践能力,开发创造思维力。文章结合教学实践,对高中化学教学中“问题链”的设计与实践进行探究。

The new curriculum standards set the cultivation and enhancement of problem awareness,the ability to discover and propose valuable questions,and the ability to independently explore and question as curriculum objectives.Teachers should design and practice the"problem chain"based on the learning situation and chapter content,allowing students to learn and construct a knowledge system in the process of discovering,proposing,exploring,and solving problems,as well as in the process of cracking material change codes and experiencing the magic of the chemical world,cultivate and improve the ability to explore and practice,inspire and develop creative thinking skills.The paper combining teaching practice with design and practice exploration of"problem chain"in senior middle school chemistry teaching.
