化学是一门以实验为基础的学科,实验是学习和研究化学的重要途径,因此,化学实验的教学效果在很大程度上决定了化学学科的教学质量。这一点在最新的《义务教育化学课程标准(2011年版)》~([1])(以下简称“课标”)中也得到了进一步的强化重视,相较于前一版课标而言,体现为不仅把实验单列为课程内容的第一主题, Chemistry is an experiment-based discipline. Experiment is an important way to study and study chemistry. Therefore, the teaching effect of chemistry experiment largely determines the teaching quality of chemistry. This point has been further emphasized in the latest edition of the Compulsory Education Chemistry Curriculum Standard (2011 Edition) ~ ([1]) (hereinafter referred to as the “Standard”). Compared with the previous version Words, reflected as not only the experiment as a single subject content for the first theme,
