化学实验在中学化学教学中有着极其重要的作用,而且随着新课程的全面实施,其重要性越来越得到彰显,无论是课堂教学还是课外活动,无论是探究式教学还是研究性学习,都离不开化学实验。但是,在实际的中学化学教学中,实验教学始终是一个薄弱环节,多年的高考实验试题得分率较低就是明证。对此,广大的中学化学教 Chemistry experiments play an extremely important role in chemistry teaching in middle schools. And with the full implementation of the new curriculum, the importance of chemistry experiments has become more and more obvious. Whether it is classroom teaching or extracurricular activities, both inquiry-based teaching and research-oriented learning Can not be separated from chemical experiments. However, in the actual teaching of chemistry in middle school, experimental teaching has always been a weak link, as evidenced by the low score of college entrance examination for many years. In this regard, the majority of secondary chemistry teaching
