基于主成份分析法的老年人信息素养体系建构

Construction of Information Literacy System for the Elderly Based on Principal Component Analysis

为了构建老年人的信息素养体系,帮助他们提高信息素养水平,选取60岁以上的老年群体作为研究对象,并采用自制量表对他们的信息素养进行调查.然后,运用主成份分析法将23个老年人信息素养指标降维为3个主成份因子.这3个主成份因子既相互独立,又能够包含原有的23个老年人信息素养指标的大部分信息,从而使老年人的信息素养问题变得简洁明了.再结合问卷内容逐一阐述3个主成份即信息意识、信息技能和信息道德的构成要素,最终成功构建老年人的信息素养体系,为老年人在社区接受信息技术教育提供科学的指导.

In order to construct an information literacy system for the elderly and help them improve their information literacy level,a group of elderly people over 60 years old was selected as the research object,and their information literacy was surveyed using a self-made scale.Then,principal component analysis was used to reduce the 23 information literacy indicators of the elderly to 3 principal component factors.These three principal component factors are independent of each other and can contain most of the information from the original 23elderly information literacy indicators,making the issue of elderly information literacy concise and clear.By combining the questionnaire content and elaborating on the constituent elements of the three main components,namely information awareness,information skills and information ethics,the information literacy system for the elderly was successfully constructed,providing scientific guidance for them to receive information technology education in the community.
