化学是一门以实验为基础的自然科学,它的知识点既多又分散,并且大量的知识还需要记忆。高中化学知识总量的增加、知识系统性与逻辑性的增强、理论知识的比重增大,对学生的逻辑推理能力、表达能力、计算能力、记忆能力及知识迁移能力的要求都大大提高了,使一部分学生产生了畏难情绪。笔者根据高中化学学科的特点和多年的教学经验,总结出如下心得。1.注重实验教学化学以实验为基础,所以实验的重要性不言而喻。课堂实验能将化学理论知识点与时间现象相结合,不仅能够强化学生对理论知识和实际操作技能的掌握,还可以培养学生发
Chemistry is an experiment-based natural science, its knowledge points are both more and more dispersed, and a lot of knowledge also need to remember. The increase of the total amount of high school chemistry knowledge, the systematic and logical enhancement of knowledge and the increase of the proportion of theoretical knowledge have greatly raised the demand for students’ logical reasoning ability, expressive ability, computational ability, memory ability and knowledge transfer ability, So that some students have a fear of emotion. The author according to the characteristics of high school chemistry and years of teaching experience, summed up the following experience. 1. Emphasis on experimental teaching Chemistry based on experiments, so the importance of experiments is self-evident. Classroom experiments can combine chemical theory knowledge points and time phenomena, not only can enhance students ’mastery of theoretical knowledge and practical skills, but also can cultivate students’ hair
