“原子量”在初中化学教材中,比較难以理解。因为一般的重量單位,像斤、兩、吨、克等,都是具体的实际重量,而原子量的單位,“氧單位”学生往往感到糢糊抽象,难以理解。在“化学通报”1955年9月号,琴仿同志所写“初中化学‘化学反应、原子、元素符号及分子式’的教学”一文中,所談到的,原子量的教学,文中一方面講物質有重量,物質由分子組成,所以分子必有重量,分子由原子組成,原子必然都有重量,原子的重量虽然微小,但是用科学方法、可以测定。但在另一方 “Atomic weight” in junior high school chemistry textbooks, more difficult to understand. Because the general weight units, such as jin, two, t, g and so on, are all concrete actual weight, the unit of atomic weight, “oxygen unit” students tend to feel fuzzy and abstract, difficult to understand. In “Chemistry Bulletin” September 1955, written by Comrade Qin imitated “junior high school chemistry” chemical reaction, atomic, elemental symbols and molecular formula ’teaching, "talked about the teaching of atomic weight, on the one hand, the substance There are weights and substances made up of molecules, so the molecules must have weight. The molecules are made up of atoms. The atoms must all have the weight. Although atomic weight is small, it can be measured by scientific method. But on the other side
