本文提出了一种基于元胞自动机的模型,用于模拟建构主义理论在教学中的应用.模型中对意义建构起作用的因素主要有情景设置、协作对话、邻居元胞作用和自身知识背景,并对它们进行了定义.试验通过模拟常见的和极端的教学设置,讨论了情景设置、协作对话两个因素对学习者意义建构的影响,得出了这两个因素的改善皆能提高学习者意义建构质量、且情景设置的影响效果稍大于协作对话因素的结论,模拟结果符合实践中观测到的学习者意义建构的变化规律.
A model of constructivism based on Cellular Automata was proposed,which was used to simu- late its application in teaching process. The major factors affecting the knowledge formation,such as situational design, cooperation and dialogue, influence of neighboring learners and self knowledge background were defined in the model. The teaching design at normal and extreme levels was simulated and the impact of situational design and cooperation and dialogue on the knowledge formation was discussed. Then ,the results are obtained ,which shows that the improvement of both the two factors can enhance the quality of knowledge formation and the positive effect of situational design is better than that of the cooperation and dialogue. The conclusions agree with the changing pattern of knowledge formation of learners observed in practice.
