化学科学本身是一门以实验为基础的自然学科,离开化学实验,化学科学就不会产生和发展。因此,作为传授化学科学知识的化学教学,必须以实验为基础。新课程标准下的实验教学提高了学生在实验教学活动中的自主性和探究性能力,促进了学生素质的全面健康发展。 Chemistry itself is a science based on the experimental nature of science experiments, chemical science will not produce and develop. Therefore, chemistry teaching as a teaching of chemical science must be experimentally based. The experimental teaching under the new curriculum standard improves students ’autonomy and inquiry ability in experimental teaching activities and promotes the overall healthy development of students’ quality.
