化学计算是中学生应具有的综合性基本技能。这一综合性基本技能,是在学生熟练地掌握化学用语,透彻地理解化学概念和灵活地运用化学知识的基础上,经过长期训练逐渐熟练的。而随着这一综合性基本技能的逐渐熟练,又能在计算化学学科的“量”的基础上,进一步强化学生对化学知识的记忆,理解和运用。因此,培养学生具有良好的计算技能,是中学生化学教学的一项重要任务。在完成这一教学任务的过程中,笔者认为,教师在培养学生注意解题程序和解题结构的前题下,应在“多解”、“精解”、“巧解”方而下功夫。
Chemical calculation is a comprehensive basic skills that middle school students should have. This comprehensive basic skill is based on students’ proficiency in the use of chemical terms, a thorough understanding of chemical concepts, and the flexible use of chemical knowledge. With the gradual mastery of this comprehensive basic skill, we can further strengthen students’ memory, understanding and application of chemistry knowledge on the basis of the “quantity” of computational chemistry. Therefore, training students with good computing skills is an important task for middle school students in chemistry teaching. In the process of accomplishing this teaching task, the author believes that teachers should be able to “multiple solutions,” “explicit solutions,” and “smart solutions” in order to develop students’ attention-solving procedures and problem-solving structures. "We’ve worked hard.
