Abstract
We examined the evaluation process for Internet information resources in searching the
web using the time-sampling technique. We gave undergraduates prior instruction,
emphasizing the importance of evaluation of information resources, and then posed
questions that would require qualitative judgment.
As a result, many of the test subjects acquired some degree of skill in search technique,
but they had some problems in critical and qualitative evaluation of the information
resources. However, the behavior of the test subject who achieved the highest score in this
experiment demonstrated particular characteristics such as a high level of information
literacy and an aptitude for critical thinking. From these findings, we construct a process
model of cognition and evaluation during information retrieval.
When we examined the movements of the mouse during web searches, (1) the most
common movement during their web page searches was scrolling and (2) the
undergraduates tended to use mouse pointers to mark information they noticed.
