1 理解和掌握反应历程的作用虽然小中专对反应历程没有教学要求,但事实上对反应历程理解得愈好,有机化学的学习就能愈深入,学生亦愈有兴趣。心理学认为,理解了的材料,在数日内可保持记忆的60%,而未理解的只能保持30%。显然,没有理解的记忆是无法堆积起知识的。 2 加强对结构、电子效应等基础知识的教学结构方面,要求学生熟悉价键理论、杂化理论,用模型展示杂化轨道空间配置,并在甲烷、乙烯、乙炔、苯的结构中反复应用。电子效应,无论是诱导效应还是共轭效应,δ_和δ+符号经常出现,其意义只是带有部分电荷(小于1个电
1 understand and master the role of the reaction process Although the school has no teaching requirements for the reaction process, but in fact the better understanding of the reaction process, organic chemistry learning will be more in-depth, students are also more interested. Psychology that understanding of the material, in a matter of days to maintain 60% of memory, but did not understand can only maintain 30%. Obviously, unknowing memories can not accumulate knowledge. 2 To strengthen the teaching structure of the basic knowledge of structure and electronic effect, students should be familiar with bond theory and hybrid theory, and to model the hybrid orbital space configuration with models. They should be repeatedly used in the structures of methane, ethylene, acetylene and benzene. The electronic effects, both inductive and conjugative, often occur with the sign of δ_ and δ +, meaning only with partial charge (less than 1 power
