通过对比分析近年来的江苏高考化学试卷可以发现,不少创新题目正在以不同的形式及不同的比例进入到师生的视野之中,开放性实验就是其中的一种题目。因为它不仅贴近学生探究性学习方法的教学要求,同时也有利于培养学生的创新意识。这也提醒化学教师应当思考如何才能更加科学高效地开展高中化学的开放性实验教学。一、用创新来引领课堂不同于“封闭式”实验,开放性实验的“开放性”在于两点,其一是方式开放。实验一般只规定需要得出的结论或 Through comparative analysis of Jiangsu college entrance examination chemistry papers in recent years, it can be found that many innovative topics are entering the field of vision of teachers and students in different forms and in different proportions. Open experiment is one of the topics. Because it not only close to the students inquiry learning method of teaching requirements, but also conducive to cultivating students’ sense of innovation. This also reminds chemistry teachers should think about how to carry out high school chemistry open experimental teaching more scientifically and efficiently. First, using innovation to lead the classroom is different from “closed ” experiment, “open ” open experiment "lies in two points, one is the way open. Experiments usually only need to draw conclusions or conclusions
