强化知识内化能力培养的教学模式研究——以“聚合动力学”教学为例

知识"内化"是个体对接收到的知识进行消化吸收、重构为学科思维的过程,可以通过梳理相关知识的研究主线、明确其基本研究方法、理清知识模块间的相互联系,构筑立体交叉知识网络体系等途径加强学生知识内化、运用能力的培养。本文以"聚合动力学"教学为例,介绍了针对上述理念的具体教学设计:以等活性假定作为贯穿聚合动力学知识体系的研究和学习主线,利用微分处理、积分处理分别作为链式聚合、逐步聚合相关计算的基本方法;将动力学链长作为关联聚合度与聚合速率的桥梁,将竞聚率作为关联共聚物组成、序列结构与单体消耗速率的桥梁。

Teaching Mode Reform to Strengthen the Cultivation of Knowledge Internalization Ability

The internalization of knowledge is a process in which an individual digests and absorbs the received knowledge and convert it to discipline thought.The students’knowledge internalization and application ability can be trained by sorting out the main line of research,finding out the basic research methods and the interconnection of knowledge modules,building interchange knowledge system.Taking the teaching of"Polymerization Dynamics"as an example,the specific teaching design of the above ideas is introduced:The equal reactivity hypothesis as research principal line runs through the knowledge system of polymerization kinetics.Differential and integral are used as the basic methods of related calculation for chain polymerization and stepwise polymerization,respectively.Dynamic chain length is regarded as the bridge between the degree of polymerization and the rate of polymerization,and the reactivity ratio as the bridge of the composition,segment sequence of copolymers between copolymerization rate.
