化学计算属于智力活动的技能范畴。所以在化学计算中,应该注意启发学生积极思维,发展学生智力。为此,我们进行如下几方面的尝试: 一、在解综合题的教学过程中培养学生分析综合能力所谓综合题就是若干基本问题的综合。学生感到困难:一方面是由于基础不牢,另一方面是由于不会分析问题。所以,教师要特别注意分析题意,帮助学生学会分析的方法,抓住训练的时机,在做法上可将题由大变小。即把综合题按层次变为若干基本题,教给学生分析过程。二、在化学计算教学中培养学生推理能力化学计算可以反映宏观规律,而宏观现象恰恰是认识微观规律的向导。利用宏观计算的结果来推断微观结论,可以很好地培养学生的逻辑推理和合乎逻辑的想象力。
Stoichiometry belongs to the category of intellectual activity skills. So in stoichiometry, we should pay attention to inspire students to actively think and develop students' intelligence. To this end, we try to do the following aspects: First, students in the process of teaching comprehensive analysis of comprehensive ability to analyze the so-called comprehensive questions is the synthesis of a number of basic issues. Students find it difficult: on the one hand, the foundation is not strong and, on the other hand, the problem is not analyzed. Therefore, teachers should pay special attention to the analysis of questions, to help students learn how to analyze, to seize the training time, the practice can be problems from big to small. That is, the comprehensive questions into a number of basic questions by level, to teach students the process of analysis. Second, in the calculation of chemistry education students reasoning ability to calculate chemical calculations can reflect the macro laws, and macroscopic phenomenon is precisely the understanding of the laws of the micro-wizard. Using the results of macroscopic calculation to infer the micro-conclusions can well cultivate students' logical reasoning and logical imagination.
