化学实验中异常现象的分析研究

Analysis and Research on Abnormal Phenomena in Chemical Experiments

在学生分组实验过程中,时常出现一些异常现象,指导教师若不及时引导,必然会使误导学生形成错误的认知,教学效果偏离教学目标。深入分析实验过程中异常现象产生的根源,运用科学的方法加以修整和引导,能够帮助学生养成求真务实、细致入微的学习习惯,提高教学质量,同时对于教师的教学能力和专业精神也是一种锻炼。为此,本文首先重点分析实现现象异常情况及其成因,继而介绍合理利用化学实验中的异常现象在化学试验教学中对于提升学生的化学学科的素养以及进一步完善也化学学科的知识架构和教学体系的重要作用。旨在通过有益的探讨不断深化化学实验教学模式,切实提高教学质量。

During the process of grouping students,some abnormal phenomena often occur.If the tutor is not timely guided,it is bound to mislead the students to form a wrong cognition,and the teaching effect deviates from the teaching goal.In-depth analysis of the root causes of abnormal phenomena in the process of experiment and using scientific methods can help students develop a realistic and meticulous study habits,improve teaching quality,and it is also a find of exercise for teaching ability and professionalism of teachers.To this end,this article focuses on the analysis of the anomaly of the phenomenon and its causes,and then introduces the important role of the rational use of the anomaly phenomenon in chemical experiments in enhancing students'knowledge of chemical discipline and further improving the knowledge structure and teaching system.It aims to continuously deepen the teaching mode of chemistry experiment and improve the teaching quality through beneficial discussion.
