《化学习题精选》是英国中学化学教师为学生提供复习和提高作业质量而编的。它的特点有:1.围绕题目编成一系列短小的问题。这些问题系按照英国现用的教材结构编写的;由浅入深,由易到难,逐步引导学生的学习兴趣;可在课内外用作讨论或练习之用。2.作者将各小题划分为三种类型:(1)知识性(以K表示),理解性(以C表示)及综合性(以H表示)。每小题都注明评分标准,用以了解学生的知识水平和分析问题、解决问题的能力。本书共有一百题,我们根据我国中学化学教学大纲的内容选译部分习题,供教师们参考、选用。选译习题中也略有超我国教材水平的,可作因材施教之用。习题的后面,附有用数字回答问题的答案。
The “Selected Questions for Chemistry” is compiled by the British High School Chemistry Teacher to provide students with review and improve the quality of their work. Its features are: 1. A series of short questions centered around the topic. These questions are based on the current structure of the UK’s teaching materials; they are shallow, deep, and easy to guide, and gradually guide students’ interest in learning; they can be used for discussion or practice inside and outside class. 2. The author divides the sub-topics into three types: (1) knowledge (in K), comprehension (in C), and comprehensiveness (in H). Each question is marked with a score criterion to understand the student’s knowledge level and ability to analyze problems and solve problems. There are a total of 100 questions in this book. We select and translate some exercises according to the contents of the Chinese middle school chemistry syllabus for teachers’ reference and selection. In the translation exercises, there are also slightly higher levels of Chinese teaching materials, which can be used for teaching students in accordance with their aptitude. Behind the problem, there are helpful numbers to answer the questions.
