做实验时 ,操作的熟练程度固然重要 ,但更重要的是实验的设计 ,即如何正确地安排实验的问题。生物科学史上一些著名的实验 ,如希尔的光反应实验、摩尔根的果蝇实验等 ,它们巧妙的设计思想 ,闪耀着智慧的光辉 ,令人赞叹不已。在中学阶段 ,实验设计既是学生进行研究性学习的一个 When doing experiments, the proficiency of the operation is important, but more important is the design of the experiment, that is, how to correctly arrange the experiment.
