Social Cognitive Network for Learners' Knowledge Building
作者 徐劉傑陳世燈
英文摘要
Knowledge building has become an evaluation factor for assessing the effect of learning, levels of cognitive development , and comprehension ability of students in online learning environment. Learners ' participation and interaction could influence the learning effect and the knowledge building level. Learners construct their social network by participating learning activities and interacting with learning peers , teachers , and experts. Learners peiformed participation behavior and interaction behavior in the process of knowledge communication, knowledge sharing, and knowledge creation. Using a case study, the development of social cognitive network within the process of knowledge building was discussed from the perspective of social network and knowledge network of the learners in online learning environment. Data collection included the learners ' demographic information , the contents of each learner' s posts , the interaction of each learner and the number of interactions between every two learners. The paper then used social network analysis method to analyze the interaction structure and to draw learners ' social network. In the aspect of content analysis , the paper extracted high-frequency keywords , and found co-keywords between learners , utilizing visualization technique to study the co-keyword network of 22 learners. It used the social network analysis to classify the co-word network and extracted six factors as six knowledge subjects. According to the co-keyword network and learners ' interactions, the paper constructed the learners ' knowledge network. Then the paper analyzed the learners ' social cognitive network by polymerizing learners ' social network and knowledge network in order to discuss learner knowledge building in online learning environment. The results showed that the social network presented the relationship of learners within online learning environment, and presented knowledge communication paths , scale , and speed. The knowledge network presented hot issues and important topics that the learners concerned. The research showed that participation and interaction of learners made an intensive social network and the knowledge network was then derived and developed in online learning environment. And learners ' social network scale and knowledge network scale were consistent with knowledge building level. In order to improve learners ' knowledge building level, it is important to reinforce learners ' interaction and participation in online learning environment. This requires teachers to change their traditional role in knowledge transfer. First, the teacher should be educational resources designer, developer, and should integrate the fragmented resources and knowledge. Second, the teacher should be cooperator, supporter and server. Third, the teacher should be the facilitators , promoters and motivators for students ' learning. Forth , the teacher should be the connectors to help learners construct social cognitive networks.
