DEVELOPMENT OF AN ITEM BANK OF BASIC KNOWLEDGE TEACHER SPIRIT FOR EARLY CHILDHOOD EDUCATION TEACHERS USING 4-PARAMETER ITEM RESPONSE THEORY

Abstract

The purpose of this research was to develop of an item bank basic knowledge of being a teacher for early childhood teachers using 4 parameter item response theory. The samples consisted of 200 early childhood education students in faculty of Education, Roi Et Rajabhat University, academic year 2020. The samples were obtained by simple random sampling. The instrument used in the research was a test consisting of 4 types of multiple-choice tests. Tests parameters were analyzed by the R packages including mirt, lavaann, Psych, and GPArotation packages. Results showed that 90 test items which was conducted at first qualified totally 60 items from the experts, and index of congruence (IOC)​ was between 0.60-1.00, and criteria for item selection requires item discriminatio between 0.800 to 5.000, item difficulty (d)​ between -​3.000 to 3.000, and 3.009, guessing probability (g)​ not over 3.000, and mistake ability less than 0.800. There were 29 items qualified for the item bank as 48.33% which included item discrimination at 0.853 to 3.009 and their mean score at 1.786 indicating that the exam has relatively high classification power. Item difficulty was between -2.674 and 2.807 which showed mean score at 0.312, indicating that the exam has a moderate level of difficulty, relatively easy. Guessing probability was between 0.041 to 0.286 average at 0.183, and mistake ability was between 0.848 and 0.989 with mean score at 0.948. The item bank was conducted by PhpMyAdmin database program which could store images and texts for developing program of computer adaptive testing.
