粘土结构和粘土-水系统辩证解析及其教学实施

Dialectical Analysis of Clay Structure and Water Based Clay System and Its Teaching Practice

对粘土结构和粘土-水系统性能进行了辩证解析。基于电荷平衡的性质,结合库仑定律,从科学角度和辩证角度对粘土荷电性质进行了分析。在此基础上对粘土结构和粘土-水系统相关性质,即粘性、可塑性、悬浮性的辩证内涵进行了分析。对课程教学中引导学生进行辩证思维以帮助学生提高学习效率的教学方法进行了探索。

The characteristics of clay structure and properties of water based clay system were dialectically introduced.Based on the electrical charge equilibrium and the Law of Kulun,the electricity carrying feature of clay is analyzed both in scientific and dialectical way.The dialectical aspect of the related performances of water based clay system,namely,viscosity,plasticity and stability of suspension were also systematically revealed.A new way to lead the students to reshape their knowledge system by introducing dialectical thinking was tried,in order to help them to study more effectively.
