Abstract

Computer adaptive testing is an important research field in educational
measurement, and simulation studies play a critically important role in CAT
development and evaluation. Both Monte Carlo and Post Hoc simulations are
frequently used in CAT studies in order to investigate the effects of different
factors on test efficiency and to compare different test designs. Although
there are several softwares for CAT simulations, R is preferred since it
includes many free packages and gives researchers opportunity to write their
own functions according to their own requirements besides being free. The
purpose of this study is to make an introduction and demonstration of how to
use catR package in CAT simulations. Different examples were provided in the
context of this study and R codes were presented with explanations. Then, the
output files were briefly explained. It is thought that this paper is helpful
for the researchers who are interested in CAT simulations.
