近年来,由于“知识爆炸”,在化学教学中狠抓知识的基本结构,加强规律性知识的教学,培养学生自我捕获知识的能力,已经引起了各方面普遍的重视。这里提供一道摘译的试题及答案。笔者认为,加强这类训练,必将有利于开发学生智力,大大提高学生综合运用知识,进行创造性思维和抽象推理的能力。〔试题〕编制周期表用拉丁字母A,B,C,…Y,z表示元素周期表中前26种元素。(注:这些字母同各种元素的实际元素符号毫无关系。)试根据以下各项说明,把这些字母填写在周期表1中的适当位置,并将各元素的原子序数填写在表2中。
In recent years, due to the “knowledge explosion”, the basic structure of knowledge in chemistry teaching, the strengthening of the teaching of regular knowledge, and the ability to cultivate students’ self-acquisition knowledge have attracted widespread attention in all aspects. Here is an excerpt of the questions and answers. The author believes that strengthening such training will certainly help develop students’ intelligence and greatly increase their ability to use knowledge comprehensively to carry out creative thinking and abstract reasoning. [Test] The preparation of the periodic table with the Latin alphabet A, B, C, ... Y, z said the first 26 elements of the periodic table. (Note: These letters have nothing to do with the actual elemental notation of the various elements.) Try to fill these letters in the appropriate places in the periodic table 1 according to the following instructions, and fill in the atomic number of each element in Table 2. .
