Measurement of Critical Viewing Skills in Web Browsing using Correspondence Analysis

摘要

The purpose of this study is to develop a measure of Critical Viewing Skills (CVS) in web browsing using correspondence analysis. To assess their CVS, children were asked to write comments about how to identify the reliability of web pages, by considering a commercial site related to dieting. Using a category system for analysis, children's and students' comments were converted to categorical data. To identify the structure of CVS categories, we used category plotting based on multiple correspondence analysis. As a result of analysis, it was found out that structure of CVS was explained with three dimensions. First dimension shows whether an attempt is being made to view information from various perspectives. Second dimension shows appropriateness of information point. Third dimension shows content and media Using correspondence analysis, the possibility was shown of being able to use correspondence analysis in evaluations without damaging CVS data obtained from students. The author would wish to develop the use of correspondence analysis in pre and post tests and an evaluation system using correspondence analysis for evaluating and improving critical viewing training programs.
