随着在线学习普及与应用，知识创造从特有现象变成了一般性活动，领域概念被视为重要“人造物”。现有研究虽然尝试解析在线学习知识创造的内涵与轨迹，但是缺乏从系统视角开展深度分析。为此，研究首先基于社会资本理论，全面剖析了在线学习知识创造的过程与特点；其次，采用数据挖掘、滞后序列等方法，基于领域概念分析了在线学习知识创造的影响。结果发现：在线学习中存在结合型社会资本与桥接型社会资本；结合型社会资本比桥接型社会资本知识创造更加高效；两类社会资本在不同教学周期下呈现多样化知识创造路径。
【英文摘要】：
With the popularization and application of online learning, knowledge creation has changed from a unique phenomenon to a general activity, and the domain concept is viewed as an important "artifact". Although existing researches have attempted to analyze the connotation and trajectory of knowledge creation in online learning, they lack in-depth analysis from a systematic perspective. Therefore, based on the social capital theory, this paper firstly analyzes the process and characteristics of knowledge creation in online learning. Secondly, based on the domain concept, this paper uses data mining technology and lag sequential analysis to analyze the influence of knowledge creation in online learning. It is found that there are bonding social capital and bridging social capital in online learning; Bonding social capital is more efficient than bridging social capital in knowledge creation; The two types of social capital present diversified paths for knowledge creation under different teaching cycles.
