耗散系统理论下信息化教学生态的演变与诊断

Research on ecological of informatization instruction under the theory of dissipative system

信息技术的快速发展,使得教学生态产生了多元化变化,系统呈现出更高的无序性.如何识别教学生态的发展阶段,以何种建设策略来促进生态的进一步发展,论文从耗散系统理论视角分析信息化教学生态的变革过程.基于技术的非线性影响、系统的远离平衡态以及保持系统负熵流的自组织原则,提出信息化教学生态重塑的三阶段,即结构变革、动力变革和开放发展,在此发展规律上构建信息化教学生态模型,并进一步结合国内外教育信息化评价指标与国家政策要求,构建信息化教学生态的熵值计算模型,并验证计算模型的可行性,评价教学信息化生态的发展状况.论文提出从变革组织结构、营造创新氛围、加快对外合作三方面来优化教师共同体的供养机制,以实现信息化教学生态发展为更高的自组织状态.

The rapid development of information technology has been promoting a diversified change in the instruction ecology which has led to a higher degree of disorder at the same time.It remains a question that how to identify the development stage of the instruction ecology and what kind of construction strategy is used to promote the further development of ecology.This paper analyzes the transformation process of informational instruction ecology based on the theory of dissipative system.Technology-based nonlinear effects,system’unbalance,and the self-organizing principle for maintaining negative entropy flow,correspond to the three stages of structural transformation,dynamic transformation and development of education ecological system.Thus,an information-based teaching ecological model under the guidance of the ecological characteristics is constructed,and an information-based teaching ecological entropy calculation model is established in the light of historical research and national policy documents.Then,it is implemented to test the calculation model and evaluate the development status of teaching information ecology.Finally,proposes to optimize the support mechanism of the teacher community are put forward from three aspects of changing the organizational structure,creating an innovative atmosphere,and accelerating foreign cooperation,so as to realize the development of information-based teaching ecology into a higher self-organizing state.
