Development of Information Technology Word Bank System for Undergraduate Students: A Differential Item Functioning

Abstract

The purposes of this research were to develop the criteria for selecting words from information technology context, and to develop the information technology word bank system for undergraduate students. The research process was divided into two phases: 1) the development of the criteria for selecting words from information technology context by synthesizing the research on word selection criteria, and 2) the development of the information technology word bank system in the form of web application, the evaluation by experts and the satisfaction of the trial users. The web application could be reached at www.thai-nbw.com. It was found that: 1. the selection criteria for information technology words was composed of four aspects: 1) unambiguous words, 2) non-jargon words, 3) common words, and 4) non-vague words; and 2. the information technology word bank system in the form of web application collected 203 information technology words that passed the content validity check as follows: 1) 59 unambiguous words had content validity index of 0.96, 2) 40 non-jargon words had content validity index of 0.91, 3) 60 common words had content validity index of 0.97, and 4) 44 non-vague words had content validity index of 0.91. The information technology word bank system is highly appropriate (Mean = 4.76). The system was recognized by the experts, and the satisfaction of the trial users was at a good level (Mean = 4.54).
