基于词频分析的社会化软件教育应用特点

Characteristics of Social Software in Education

Web2. 0 时代的到来、互联网的升级给人类学习提供了新技术支撑。近年来，在教育技术领域广泛开展了社会化软件的教育应用研究。本文采用词频分析法对已有研究文献进行内容分析，结果显示，社会化软件虽有共同之处，但又各具特点，例如，博客适合学习反思，维基适合知识管理，播客适合学习者自学，RSS 适合信息推送和聚合。这些特点对于教学的某一环节或某一学习活动具有独特的优势，但不存在适合任何教学内容和所有学习者的万能媒体，关键是将社会化软件教育应用特点与学习活动创设两者之间建立起联系，根据教学需要恰当选择社会化软件，实现技术在教学中的消融，从而促进最优化学习的发生。
