【中文摘要】:
以观点为中心的知识建构理论强调学习者像科学家一样探究真实问题,多个观点持续交互使得社区逐渐演变成一个复杂系统,非叠加态的观点呈现出不能被还原的涌现现象。然而目前对于观点涌现的研究止步于理念上对其系统属性的认识,仍然惯性地沿袭还原论的研究视角及范式,将复杂的涌现现象切割为单个观点甚至是片段化的关键词进行挖掘与分析,未能真正触及观点涌现的实质。基于此,本研究采用自下而上的多主体建模来探索观点涌现的规律和特征。研究发现,观点涌现层级越高需要的时间越长,难度也越大;高层级的观点会限制低层级观点的交互域;观点涌现过程中的能量值呈现从正态分布到指数分布的不均衡态势,从而为观点涌现研究提供了全新的视角和方法,对知识建构社区的教学实践具有多层次的解释力。
【英文摘要】:
Idea-centered knowledge construction theory emphasizes that learners explore real problems like scientists. The continuous interaction of multiple ideas makes the community gradually evolve into a complex system, and the non-superpositional ideas present an emergent phenomenon that cannot be reduced. However, the current research on emergence of ideas stops at the conceptual understanding of its systematic properties, and still follows the research perspective and paradigm of reductionism, cutting the complex emergence phenomenon into a single idea or even fragmented keywords for mining and analyzing, which fails to truly touch the essence of idea emergence.
