元素周期表(律)知识体系教学策略的思考

Reflection on the Teaching Strategies of Periodic Table (Laws) Knowledge System

元素周期表(律)是物质结构知识体系非常重要和最具代表性的组成部分,具有非常丰富的科学内涵,蕴含复杂严密的逻辑关系。教学中引导学生深刻分析周期表中各种或显或隐的逻辑关系和事物矛盾,有助于提高学生的思维推理和问题解决能力,有助于提升学生的化学学科思想和哲学辩证理念,有助于提振学生学习的信心和兴趣。从大学教师的视角对元素周期表和元素性质周期性知识体系的教学策略进行了探索和讨论。

The periodic table(law) is a very important and most representative part of the knowledge system of material structure, which has very rich scientific connotation and contains complex and strict logical relations. In teaching, students are guided to deeply analyze various logical relations and contradictions of things in the periodic table, which is helpful to improve students’ thinking, reasoning and problem solving ability, to cultivate students’ chemical subject thought and philosophical dialectical concept, and to enhance students’ confidence and interest in learning. The teaching strategies of periodic table knowledge system and periodicity of elemental properties are explored and discussed from the perspective of university teachers in this paper.
