化学是一门以实验为载体的学科,实验在化学教学中的作用不可小觑,以科学探究为突破口的新课改要求我们在化学教学中注重三维目标的整合和落实;实践表明:以控制变量思想设计的化学实验一直贯穿初中化学教学的全过程;笔者从事初中化学教育教学多年来,一直比较关注化学实验教学的直观性、形象性和实效性,笔者在本文中采取理论与教学实践案例
Chemistry is an experiment-based discipline. The role of experiment in chemistry teaching should not be underestimated. The new curriculum reform that takes scientific inquiry as a breakthrough requires that we pay attention to the integration and implementation of three-dimensional goals in chemistry teaching. Practice shows that: The chemical experiment of variable thought design runs through the whole process of junior high school chemistry teaching. The author engaged in chemistry education teaching of junior high school for many years, has been more concerned about the visualization, visual and practical effect of chemistry experiment teaching. The author adopts the theory and teaching practice case
