摘要：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。
Abstract: Teachers' knowledge sharing plays an important role in promoting teachers' online training. In order to reveal the micro-mechanism of how the influencing factors of teachers' knowledge sharing strategy selection in the online training space change over time, this research explored the structure of teachers' knowledge sharing network, constructed an evolutionary game model by combining the complex network theory, and used simulation techniques to dynamically deduce the diffusion phenomenon of teachers' knowledge sharing behaviors with the scale-free network as the carrier. The research found that teachers' knowledge collaboration ability, knowledge sharing benefits, and knowledge sharing costs have significant impacts on teachers' adoption of knowledge sharing strategies. Compared with large-scale knowledge sharing networks, small-scale knowledge sharing networks are more sensitive to teachers' choice of sharing strategies. When the knowledge sharing network evolves for a certain number of times, the degree of network central nodes has no significant impact on teachers' choice of knowledge sharing strategies. Based on this, the research put forward relevant suggestions for teachers' knowledge sharing in the online training space.
