论基于模型建构的概念转变教学模式

模型是对目标系统的简化的表征.模型建构是一种基于模型的建构性学习活动.根据认知心理学的观点,概念转变是学生朴素模型向科学模型转变与建构的过程.模型建构过程包括四个阶段的循环:激活原有朴素模型中的错误概念;对模型中的元素产生不满(产生认知冲突);建构新模型;使用新模型.基于模型建构的教学模式能促进概念转变,这一模式包括聚焦学生朴素模型中的错误概念;引发学生的认知冲突;通过类比推理,建构新模型;使用新模型,进行科学推理.

On Conceptual Change Teaching Model Besed on Modeling

The model is a simplified representation of the target system.mental.The modeling is a of model-based constructive learning.According to the view of cognitive psychology,conceptual change is the process of the change and construction from student's naive models to scientific models.Modeling include four stage circulations: activating on misconception of original naive models,producing dissatisfaction in the model element(producing cognitive conflict),construcing new model,and using new model.Model-based mod...
