论文部分内容阅读
现行高中《生物》课本中名词、简称、代号较多,学生在学习过程中极易一知半解(甚至生吞活剥)而死记硬背.为此,近几年来,我们作了一些探索,在讲述这些内容时,尽量注意介绍“由来”. 如在讲“细胞膜的结构”时,我们向学生介绍细胞膜结构的发现史:1895年,奥弗顿发现溶于脂肪的物质易透过细胞膜,首先提出了脂质膜的论点;1925年,戈特发现红细胞的全部脂类铺成单分子层时,恰好是红细胞的表面积的2倍,从而提出细胞膜是由两层磷脂分子组成的理论(红细胞中无其他膜成分).又如在讲“高尔基体”时,我们向学生介绍高尔基体的发现者是意大利的神经解剖学家高尔基(Golgi).1898年,他首先描述其为细胞器,因此叫做高
In the current high school “Biology” textbook, there are many nouns, abbreviations, and more code names, so students can learn very hard to understand even during their learning process. Therefore, in recent years, we have made some explorations to explain these contents , As much as possible to introduce the “origin.” As in the “cell membrane structure”, we introduce students to the discovery of the history of cell membrane structure: In 1895, Overton found that fat-soluble substances easily through the cell membrane, first proposed lipid Membrane 1925, Gott found that when all the lipids of erythrocytes were spread into a monolayer, they were exactly twice as much as the surface area of the erythrocytes, suggesting that the cell membrane was composed of two layers of phospholipid molecules (no other membrane components in the red blood cells In another example, when we talk about the Golgi we introduced Golgi to the discoverer of Golgi, the Italian neuroanatomist Golgi, who first described it as an organelle in 1898,
