学起源于思,思源于疑。在从事化学教学的十年中,我一直被一个问题反复困扰着,那就是问题式教学在实验课堂中的运用。从开始的初步重视,到这届学生在学习过程中出现的一系列问题所带给我的经验和思考,让我意识到问题式教学在高中化学实验教学中运用的重要性。传统的实验教学模式不利于激发学生 Learning originated from thinking, thinking from doubt. In the ten years of teaching chemistry, I have been repeatedly troubled by a problem, that is, problem-based teaching in the experimental classroom. From the initial consideration, to the experience and thinking brought by this series of students’ problems during the learning process, I realized the importance of problem-based teaching in high school chemistry experiment teaching. The traditional experimental teaching mode is not conducive to inspire students
