摘要:

提出并纠正了“聚合反应能够自发进行的判据是△G < 0”“理想共聚中两种活性中心活性相同”“丙烯酸二茂铁甲酯(FMA)比丙烯酸-2-二茂铁乙酯(FEA)有更高的均聚速率常数”“3-对甲苯丙烯酸甲酯(4-甲基肉桂酸甲酯)可以聚合得到高聚物”以及“α-氰基丙烯酸甲酯不能进行自由基聚合”等高分子化学教学中长期存在的5个似是而非的典型问题,并且通过这些问题的提出与解决,启发、引导、鼓励学生由学而思,由思而疑,由疑而问,由问而究,由究而得,由得而知。使其在正确获取知识的同时,批判性思维、问题转换能力及查阅文献的意识得到培养,也使其发现问题、提出问题、分析问题、解决问题的意识及能力得到提高。

Abstract:

Five typical specious questions in polymer chemistry were discussed, including "the criterion of the spontaneity of a polymerization is △G < 0", "the activities of the two kind of active centers in an ideal copolymerization are the same", "ferrocenylmethyl acrylate (FMA) has a higher propagation rate constant of homopolymerization than 2-ferrocenylethyl acrylate (FEA)", "Methyl 3-(4-methylphenyl)-2-propenoate, or Methyl 4-methylcinnamate, can be homopolymerized into high polymer" and "α-cyanoacrylate cannot be free radically homopolymerized". Through raising and answering these questions, the students were encouraged to think, to doubt, to question, to explore, to acquire, and to understand under the teacher's inspiration and guidance. This helps to train the critical thinking skills, the problem conversion ability and the literature consulting awareness, to build the awareness and abilities of problem finding and problem raising, and to develop the ability to analyze and solve problems, in addition to acquire the right knowledge.

Key words: Polymer chemistry, Teaching, Critical thinking, Problem conversion ability, Literature retrieving, Awareness development
