我们根据教学大纲和教科书体会本章的教学目的有下列几点:(1)使学生了解碳的各种同素异性体及碳在自然界的存在,并认识碳对国民经济的重大意义。(2)使学生了解碳的氢化物—甲烷的制法与性质,知道甲烷是最简单的一种有机化合物,同时初步认识有机化合物的意义,为下一章学习有机化合物准备条件。(3)使学生了解碳的氧化物的制法、性质与用途,并认识碳酸盐的性质、存在与应用。(4)通过碳与卤族元素、氧族元素及氮族元素的非金属性质和化合价的比较,打好学习门捷列夫周期表的基础。
The following are some of the teaching objectives we have come to realize from this syllabus and textbook: (1) To enable students to understand the various types of carbon allotropes and the existence of carbon in nature and to recognize the great significance of carbon to the national economy. (2) To enable students to understand the preparation and nature of carbon hydride, methane, knowing that methane is the simplest organic compound and meanwhile understanding the meaning of organic compounds and preparing conditions for the next chapter on organic compounds. (3) to enable students to understand the system of carbon oxides of law, nature and use, and recognize the nature of carbonates, existence and application. (4) Make a good study of Mendeleev’s periodic table by comparing the nonmetal properties and valences of carbon, halogen, oxygen and nitrogen groups.
