网络研修空间中教师知识共享网络策略演化研究

Research on the Evolution of Knowledge Sharing Strategies in Online Teacher Professional Development

教师知识共享对促进教师网络研修具有重要作用。为揭示网络研修空间中教师知识共享策略选择的影响因素随时间变化的微观机制,研究探索了教师知识共享网络的结构,结合复杂网络理论构建演化博弈模型,利用仿真技术,动态演绎了以无标度网络为载体的教师知识共享行为的扩散现象。研究发现,教师知识协同能力、知识共享收益和知识共享成本对教师采取知识共享策略有显著影响;相较于大规模知识共享网络,小规模知识共享网络对教师共享策略的选择更敏感;当知识共享网络演化一定次数后,网络中心节点度对教师知识共享策略的选择无显著影响。据此,研究为网络研修空间中教师知识的共享提出了相关建议。

Teacher knowledge sharing is crucial in promoting online professional development. This study explores the structure of teacher knowledge-sharing networks to reveal the evolving micro-mechanisms influencing teacher knowledge-sharing strategies in online spaces. Combining the complex network theory, an evolutionary game model is constructed and simulation techniques are employed to dynamically deduce the diffusion of knowledge-sharing behaviour among teachers within a scale-free network environment. The findings indicate that teacher knowledge collaboration ability, knowledge-sharing benefits, and costs significantly impact their sharing strategies. The smaller knowledge-sharing networks are more sensitive to teachers' strategy choices than the larger networks. After a certain number of evolutions within the knowledge-sharing network, the centrality of network nodes does not significantly affect teachers' knowledge-sharing strategy choices. Based on these findings, recommendations are made to enhance knowledge sharing among teachers in online teacher professional development.
