A Prototype of Online Adaptive Testing System Using Sequential Probability Ratio Test Model Case Study: Basic English

Abstract

Computerized adaptive testing (CAT) system is a method of assessment which the computer selects and presents test items to examinees according to the estimated examinee’s ability levels. The objective of this research aims to develop the CAT system with Sequential Probability Ratio Test (SPRT) model that has ability to generate the customize test items from a small-scale item bank. This proposed system was developed by PHP, JavaScript, CSS and MySQL. The Basic English item bank in this prototype is constructed from O-Net examination for system performance testing based on software engineering principles and system requirement specifications. This system was assessed using a questionnaire examining user interface, ease of use, validation and functional requirement. The result of the questionnaires showed that
the efficiency of this system is satisfied and it is possible to deploy this system for our students practically.
