摘要:化学演示实验是传授知识的重要手段,也是培养学生探索精神和创新能力的一块基地。在化学课堂教学中,可以通过增设演示实验、改进演示实验、“下放”演示实验、 对比演示实验、多媒体辅助突破演示实验、“提升”演示实验等途径,提高演示实验的探索性。本文从新课程教学要求出发,对中学化学演示实验从目前中学实验教学现状、演示实验的教学模式、演示实验的实施途径、演示实验的改进等方面进行分析探索,从而在教学中能激发学生应用化学实验探索问题解决问题的能力。
关键词:演示实验 教学模式 实施途径 探索 改进
Abstract: chemistry is an important method to impart knowledge and also a base piece to cultivate the spirits of exploration. In the chemistry teaching, we can improve the exploration of the demonstrated experiments through the addition of demonstrated experiments, improving demonstrated experiments, putting down demonstrated experiments, contrasting demonstrated experiments, applying multi-media to demonstrated experiments, promoting demonstrated experiments. In the article, I start from the requirements of new curriculum teaching, exploring the demonstrated experiments from the following four aspects:
Teaching methods of demonstrated experiments, implementation approaches of demonstrated experiments, the explorations of demonstrated experiments,
to motivate the student’s abilities of applying chemistry experiments to solving problems
Key words: demonstrated experiment; teaching methods; the way to implement; explore; improve
