THE DEVELOPMENT OF EXAMINATION ITEMS BANK: A CASE STUDY OF GENERAL EDUCATION AT SUAN SUNANDHA RAJABHAT UNIVERSITY

Abstract

Study on the Development of a General Education Exam Question Bank. The objective of this study is to enhance the General Education exam question bank through the following steps: 1) Content Validity Analysis: Conducting a content validity analysis by determining the Item-Objective Congruence (IOC) through the perspectives of three experts, consisting of 160 items. 2) Difficulty and Discrimination Analysis: Analyzing the difficulty (p) and discrimination (r) values for each item and 3) Reliability Analysis: Determining the reliability of the exam by calculating the Kuder-Richardson Formula 20 (KR-20) and selecting questions that meet the established standards for inclusion in the question bank. The study involved testing the developed question bank on a sample group of 2,003 students using an 80-item test. The analysis revealed that the reliability of the exam, as measured by KR-20, was 0.829. This indicates that the test has a high level of reliability in assessing learning outcomes. Furthermore, the difficulty values (p) ranged from 0.04 to 0.98, signifying a diverse range of difficulty levels from challenging to relatively easy. The discrimination values (r) ranged from -0.13 to 0.49, suggesting acceptable discriminative power. The study identified a subgroup of high-scoring (H) and low-scoring (L) students, comprising approximately 27% each, totaling around 540 individuals in each group. The overall findings suggest that this exam is highly reliable and effective in assessing learning outcomes.
