论文部分内容阅读
从现行化学教材看,出现的化学用语有:元素符号(33种);离子符号(5种);原子结构示意图(22种);离子结构示意图(5种);化学式(108种);化学方程式(62个);电离方程式(11个)。新编教材不仅删去了电子式,减少了元素符号,降低了对原子(或离子)结构示意图的学习要求,对单质、氧化物、酸、碱、盐之间相互联系与相互转变的反应规律的学习要求,而且对章节编排做了改进,分散了难点,选择了合理的知识梯度。
From the current chemistry teaching materials, the chemical terms that appear are: Elemental Symbols (33 species); Ion Symbols (5 species); Atomic Structure Schemes (22 Species); Ion Structure Schemes (5 Species); Chemical Formulas (108 Species) (62); ionization equation (11). The new textbook not only eliminates the electronic type, reduces the element symbols, reduces the learning requirements for atomic (or ionic) structure diagrams, and the reaction rules for the interrelation and mutual transformation of simple substance, oxide, acid, alkali and salt Learning requirements, but also made improvements to the chapter choreography, scattered difficulties, choose a reasonable knowledge gradient.
