Tremendous amount of information is being produced and is disappearing everyday in today's
information society, and for learners there is great difficulty in organizing and reproducing the
necessary information relying solely on the existing information-acquiring learning method that is
taught unilaterally in schools. There is a greater demand for learners, including elementary school
students, to be able to select the necessary information out of the numerous information available in
their surroundings, and be able to analyze and reorganize them in order to produce new information
suitable to their own needs.
Information literacy, or the ability to utilize new information after acquiring, synthesizing, and
analyzing existing information is increasingly becoming crucial - as much as the ability to read - for
learners in information society, and as one's proficiency in it increases, the opportunity to come in
contact with various data that information-orientated society can provide and the ability to optimally
select and apply the right information correspondingly increase.
There are various modes of thinking learners need to possess today, but among these, critical
thinking emphasizes reliability of evidence and validity of arguments as a rational and reflective
method of thinking used to determine what to believe and how to act.
An increase in critical thinking ability is possible by developing related elements and utilizing
various programs on scenes of learning, and this research examines the influence activities based on
Irving's info-literacy model has on critical thinking power (areas of function and tendency), and the
change in information literacy they bring to high, intermediate, and low group of critical thinking
ability.
