Computer Adaptive Test Development To Assess Students’ Psychology

Abstract

Psychology stability plays great role in students’ learning, and stress becomes a
significantly serious issue among university students. An efficient tools is
needed to understand it more. The aim of present study is to develop a
Computerized Adaptive Testing (CAT) as pioneer project in South East Asia,
and starting in Vietnam. In this vein, an item bank of 68 items has been
constructed, which is based on Likert Polytomous Scales through five subdomains:

behavior, academic performance, family, lecturer and finance. It has
assessed 2,085 students (704 males and 1,381 females). Multidimensional
Random Coefficients Multinomial Logit (MRCML) Model is applied to
develop Multidimensional Stress Scales and Computerized Adaptive Testing
procedure. The result findings indicate that Multidimensional Random
Coefficients Multinomial Logit (MRCML) can be used to develop new scale
with psychometric properties. Indicated by various fit criteria MNSQ, standard
errors, Z (t-test) implemented in software ConQuest. The sub-domain has a
good reliability (from .857 to .798). As respect to CATs, a simulated experiment based on the empirical data is applied to evaluate the performance of the proposed computerized adaptive testing. The standard error of the estimated stress proficiencies are reported in this study. The 68 items stress data appropriate fit the Multidimensional model applied.
