化学是一门以实验为基础的自然科学,实验在化学科学研究与发展中占有重要的地位,也是学生学习化学必不可少的手段和方法。在实际的教学中,教师除了应用教材中的实验进行教学外,还会从不同角度对实验进行创新,优化实验教学过程。下面笔者就以2013年北京市初中化学教师实验技能与教学展示活动的区县培 Chemistry is an experiment-based natural science. Experiments occupy an important position in the research and development of chemical science. It is also an indispensable means and method for students to learn chemistry. In the actual teaching, in addition to teaching teachers in the application of teaching experiment, but also from different angles to experiment innovation, optimize the experimental teaching process. The following author on the 2013 Beijing junior high school chemistry teachers experimental skills and teaching demonstration activities in the district and county training
