化学计算在整个化学教学过程中占着重要的位置。全日制十年制学校《中学化学教学大纲(试行草案)》指出,“进行化学计算能使学生从量的方面来理解物质及其变化的规律,并获得化学计算的基本技能技巧”。在统编化学教材中共选编了711道习题,其中就有205道计算题,占总数的27.7％。因此,在教学中教师要有目的、有计划地经常不断地对学生进行化学计算的技能和技巧的训练,培养化学计算的能力。
Chemical calculations occupy an important position in the entire chemistry teaching process. The full-time 10-year school “Chemistry Syllabus for Middle Schools (Trial Draft)” pointed out that “to carry out chemical calculations enables students to understand the laws of matter and its changes from the quantitative aspect, and acquire the basic skills of chemical calculation techniques.” A total of 711 exercises were compiled and compiled in the textbook of textbook compilation. Of these, 205 were calculated, accounting for 27.7% of the total. Therefore, in teaching, teachers should regularly and systematically train students in the skills and techniques of chemical calculations and develop the ability of chemical calculations.
