不同学科知识间的联系对比,比如苏教版化学必修一第一单元学习的是物质的分类方法,此时就可以引导学生思考,其他学科中有没有学过分类这个知识呢?比如生物学中有没有分类呢?学生经过思考,有的,生物分为植物和动物,动物又分为脊椎动物和无脊椎动物,脊椎动物还可以再细分.语文中的分类也很常见,可以将词分为名词、动词、形容词、数词、量词等.数学中可以将数分为正数、负数,整数、分数等.看来一切学科都要涉及到分类这个知识,这也是认识世界的最基本的方法.在讲化学反应与能量变化的时候,可以联系物理中的知识,自然界多数的反应都是向着能量减
Comparison of different disciplines of knowledge, such as the Soviet version of chemistry compulsory first unit to learn the material classification method, this time you can guide students to think about other subjects have not learned the classification of this knowledge? Such as biology There is no classification? Students after thinking, and some, biological is divided into plants and animals, animals are divided into vertebrates and invertebrates, vertebrates can also be subdivided. Classification of the language is also very common, you can word As nouns, verbs, adjectives, nouns, quantifiers, etc. Mathematics can be divided into positive numbers, negative numbers, integers, fractions, etc. It seems that all disciplines involved in the classification of this knowledge, which is the most basic understanding of the world Method. Speaking of chemical reactions and energy changes, you can contact the knowledge of physics, nature, most of the reactions are toward energy reduction
