中学化学实验多注重实验功能的验证性,而忽略其探索性,即按有关条件及步骤“照方抓药”来验证某种物质的性质、制法及某个化学原理,而忽略了科学家们当初发现这些性质、制法及原理的探索过程。这样的实验教学最多只能将前人的经验传授给学生,而不能很好地培养学生的创造性思维,而培养创造性思维是培养创新能力的关键,因此,我们很有必要将验证性实验变为探索性实验,从而有意识地在实验教学过程中培养和发展学生的创造性思维。
Chemistry experiments in middle schools pay more attention to the verifiability of experimental functions while ignoring their exploratory nature, that is, to verify the nature, preparation method and certain chemical principle of a substance according to the relevant conditions and steps We had discovered the exploration process of these nature, system of law and principle. Such experimental teaching at most can only pass on the experience of previous students to students, and can not cultivate students’ creative thinking very well. Developing creative thinking is the key to cultivating innovative capabilities. Therefore, it is necessary for us to turn confirmatory experiments into Exploratory experiments, so consciously in the process of experimental teaching to develop and develop students’ creative thinking.
