多年来,我多半是从事《无机化学》等课程的教学工作。但无机化学教学,特别是元素部分,均面临着一些普遍性的问题:即学生经常反映“理论难懂,性质难记,方程式太多……”,82级李××说:“唐老师,我一打开无机化学书,似乎也看得懂,但一合上书,就什么也记不得了,……。”83级周×说:“电子云、原子轨道等太抽象了……”。83级王××说:“如H_2O_2既有氧化、还原性,又有不稳定性等多种性质,那么它同氯气能否发生反应?如能反应,H_2O_2显示什么性质?那反应产物是什么?化学方程式该如何写?……。”84级王××说:“几百页书,怎么记得了?!我看了几个钟头书后,不知不觉就睡觉了……。”诸如此类的说法,不再赘述。认为结构理论抽象难学,感到无机知识杂乱无章,枯燥
Over the years, I mostly engaged in teaching “inorganic chemistry” and other courses. However, the teaching of inorganic chemistry, especially the elemental part, all face some common problems: students often reflect “the theory is difficult to understand, the nature is hard to remember, the equation is too much ...”, Grade 82 Lee said: “Teacher Tang, As soon as I opened the book of inorganic chemistry, I seemed to understand it, but when I closed the book, I could not remember anything ... .... ”Week 83 said:“ The electron cloud and atomic orbit are too abstract ... ”. 83 Wang XX said: “If H_2O_2 both oxidation, reduction, and instability and other properties, it can react with chlorine? If it can react, H_2O_2 show what nature? What is the reaction product How to write a chemical formula ... .... ”84 Wang XX said:“ Hundreds of pages of books, how do you remember ?! I read a few hours after the book, unconsciously went to bed ... ... ”And so on ,No longer. It is difficult to learn the abstract of structure theory, and the inorganic knowledge is disorganized and boring
