在高中生物实验教学过程中,我们经常发现不少学生只重视实验结,不重视分析结果,仅仅是关注于实验成功,而实验失败的原因却不愿对其分析。造成这种现象的原因之一是学生对实验的根本目和认识缺乏深刻的理解,不懂去分析实验的结果、没有掌握实验分析的一般方法。生物学是实验性很强的一门学科,实验过程中,我们会发现有很多种因素影响实验结果,导致实验的失败。这时,分析实验就很重要了。一方面,找出影响因素并排除,使实验的再一次进行获得成功;另一方面,从中得到经验教训,还可能获得意外的收获、新的结果,这在科学史上是不乏其例的。
In the process of high school biology experiment teaching, we often find that many students only attach importance to the experimental conclusion, do not attach importance to the analysis result, just focus on the experimental success, and the reason of the experimental failure is unwilling to analyze it. One of the reasons for this phenomenon is that students lack a deep understanding of the fundamental purpose and understanding of the experiment, do not know how to analyze the experimental results, and do not master the general methods of experimental analysis. Biology is a highly experimental subject. During the experiment, we will find that there are many kinds of factors that affect the result of the experiment, leading to the failure of the experiment. At this point, it is important to analyze the experiment. On the one hand, identifying and eliminating the influencing factors will make the experiments succeed again. On the other hand, if we learn from them, we may get unexpected gains and new results. This is a case in the history of science.
