素质教育的核心是培养学生的创造力。为了培养学生的创造力,就要激发学生的学习兴趣和动手欲望,清除那些干扰和抑制学生学习兴趣和动手欲望的不利因素。就化学实验而言,认识和解决学生在分组实验中所暴露出的问题很有必要,因为这对培养和提高学生学习化学的兴趣和动手能力很有帮助。下面笔者将根据自己工作的实际情况粗浅地谈一下这个问题。一、预习问题预习实验主要是将实验的内容和要求简要地罗列出来,起到事前心中有数的作用,这既有利于对理论知识的再认识,又有利于激发学生的动手欲望。尽管教师会在分组实验前要求学生预习实验内容,但很 The core of quality education is to cultivate students’ creativity. In order to cultivate students’ creativity, it is necessary to inspire students’ interest in learning and their desire to act, and to eliminate those unfavorable factors that interfere with and inhibit students’ interest in learning and their desire for action. As far as chemistry experiments are concerned, it is necessary to understand and solve students’ problems exposed in the grouping experiment because it is very helpful for cultivating and improving students’ interest in learning chemistry and hands-on ability. The author will talk about this issue according to the actual situation of his work. First, prepare for the problem The pre-requisite experiment is mainly to briefly list the content and requirements of the experiment and play a role in it. This will not only help to recognise the theoretical knowledge, but also help stimulate students’ desire for action. Although teachers will ask students to preview the experiment content before grouping experiments, it is very
