熵理论指导下的化学开放性教学模式探究

Open Chemistry Teaching Model Under the Guidance of Entropy Theory

熵定律这一自然界的重要定律也被认为是“一种新的世界观”.熵是一个不断被深化与泛化的概念.教学过程也是不断从低级有序向高级有序转化的过程,即是从“高熵”走向“低熵”.用熵理论指导开放性教学模式,以“化学能转化为电能”为例进行课堂教学,从低级有序状态到非平衡态,输入新的教学手段、教学方式——涨落,通过非线性作用达到新的高级有序阶段.为学生的学习创造了一个广阔的思维空间和全方位、多层次、多渠道的学习环境.

The entropy theory is such an important law of nature that has been also regarded as "a novel worldview". Entropy is a being deepened and generalized conception. The teaching process should be a transformation process from low level to senior level order, that as from"high entropy" to "low entropy". Chemistry classroom teaching under the guidance of entropy theory requires teachers to use teaching system as an opening mode, requires the transition from lower orderly to non-equilibrium status, input new teaching tools and modes: "Fluctuation",and reach a new higher orderly phase through the non-linear effect, which has been illustrated by "the transfer of chemical energy to electrical energy" in the class. This kind of teaching mode will create a wide thinking space and an all-round, multi-level and multi-channel environment for students’ study.
