This article defines the origin of an internet-centered language assessment (ICLA), how ICLAs are different from the other traditional computer-oriented tests, and what uses and functions ICLAs have in different taxonomies of language testing. After a very short review of computer- oriented testing, ICLAs are defined and categorized in low-tech or high tech categories. Since low-tech tests are ...

This article focuses on the use of computers in Language Testing. The first part of the article gives a general introduction to three different kinds of tests administered with a computer: (1) computer-based tests (CBTs), (2) computer-adaptive tests (CATs), and finally (3) web-based tests (WBTs). On the other hand, the second part of the article focuses on self-assessment and web-based tests, p...

Testlet response theory (TRT) is a measurement model that can capture local dependency in testlet-based tests. One of the purported advantages of TRT over the more commonly-used polytomous IRT approach to modeling testlet-based tests is that it allows for ad hoc testlet construction in a testlet-based computer adaptive test (CAT). The goal of this study was to investigate the merits of such a C...

The process of constructing a fixed-length conventional test frequently focuses on maximizing internal consistency reliability by selecting test items that are of average difficulty and high discrimination (a “peaked” test). The effect of constructing such a test, when viewed from the perspective of item response theory, is test scores that are precise for examinees whose trait levels are near ...

BACKGROUND Quality of life (QoL) questionnaires are desirable for clinical practice but can be time-consuming to administer and interpret, making their widespread adoption difficult. OBJECTIVE Our aim was to assess the performance of the World Health Organization Quality of Life (WHOQOL)-100 questionnaire as four item banks to facilitate adaptive testing using simulated computer adaptive test...

The assessment of a person’s traits is a fundamental problem in human sciences. Compared to traditional paper & pencil tests, computer based assessments not only facilitate data acquisition and processing but also allow for adaptive and personalized tests so that competency levels are assessed with fewer items. We focus on speeded tests and propose a mathematically sound framework in which late...

The spacecraft simulator robust control through H∞-based linear matrix inequality (LMI) and robust adaptive method is  implemented. The spacecraft attitude control subsystem simulator consists of  a  platform, an air-bearing and a set of four reaction wheels. This set up provides a free real-time three degree of freedom rotation. Spacecraft simulators are applied in upgrading and checking the c...
