化学计算习题可以帮助学生巩固和加深一些重要的概念,能应用它们来检查学生掌握知识的情况。更重要的是能使学生具体地运用已得的知识来解决运算的题目,既能培养学生推理能力又能训练学生独立计算能力。通过知识的运用和思维的活动,帮助他们自觉地掌握教材和激发他们学习化学的兴趣。此外通过计算还能使学生了解生产上的使用原料和实际产量的关系等等。中学有机化学部分的计算习题的类型是比较少 Stochastic Calculations can help students consolidate and deepen some important concepts that can be used to check students’ knowledge of the situation. More importantly, students can use the knowledge they have to solve the problem of computing, not only to cultivate students ’reasoning ability but also to train students’ independent computing ability. Through the use of knowledge and thinking activities, to help them consciously grasp the teaching materials and stimulate their interest in learning chemistry. In addition, through the calculation can also enable students to understand the use of raw materials on the production and the actual relationship between yield and so on. The type of computational exercises in the organic chemistry section of secondary school is relatively small
