最近几年中考化学实验题目的分值比例逐年增加,说明初中化学实验操作越来越被重视,说明化学课堂由主要传授基础知识向实验操作转化,调动学生参与化学教学的积极性,暗示化学实验课不仅要提高学生的观察、动手等能力,同时还要培养学生化学实验的创新能力。这要求化学教师的教学理念和教学模式要与时俱进,不断更新和创新。 In recent years, the proportion of the subjects in the senior high school entrance examinations increased year by year, indicating that junior high school chemistry experiment operation is more and more attention, indicating that the chemistry classroom from the main transfer of basic knowledge to experimental operation, to mobilize students to participate in chemistry teaching enthusiasm, suggesting that chemistry experiment class Not only to improve students ’observation, hands-on ability, but also to cultivate students’ innovative ability of chemical experiments. This requires chemistry teachers teaching philosophy and teaching mode to keep pace with the times, continuous innovation and innovation.
