化学基础知识一般都是比较高度的抽象理论知识,无从直观,学生难以理解和掌握,在讲授时,最好能采取一些切实有效的措施。现谈谈个人的一些作法,以供商榷。一、应用比较法讲授化学基础知识比较法就是因两个或两类物质某些属性相同,由一个推知另一个属性相同物质的思维方法。我们要善于把难懂的抽象的理论知识通过与浅显易懂的知识作比较,来达到掌握我们所要学习的知识的目的。例如,在有机化学教学中讲授炔烃的化学性质时,把炔
Chemical basic knowledge is generally a high degree of abstract theoretical knowledge, can not be intuitive, difficult for students to understand and grasp, in teaching, it is best to take some practical and effective measures. Now let's talk about some personal practices for discussion. First, the application of comparative law to teach the basic knowledge of chemistry Comparative method is due to two or two substances of some of the same attributes, by inferring another attribute of the same material thinking method. We should be good at using abstract theoretical knowledge that is difficult to understand to comprehend what we want to learn by comparing it with plain knowledge. For example, when teaching the chemistry of alkynes in organic chemistry teaching, alkyne
