Item banking with Rasch Measurement: An example for primary mathematics in Thailand

Chaowprapha Chuesathuchon; Russell Waugh

This study was conducted in Thailand to create a Mathematics item bank and a Computerized Adaptive Test (CAT) for the students to ‗interrogate‘ the bank. First, 290 multiple-choice test items on mathematical equations were created for an item bank. They consisted of nine aspects: (1) identifying an equation; (2) identifying the true equation; (3) identifying equations with an unknown; (4) finding the value of an unknown that satisfies the equation; (5) identifying a method to solve an equation; (6) finding the solutions to equations; (7) finding a solution to an equation related to a given condition; (8) selecting an equation converted from a verbal problem or a verbal problem related to an equation; and (9) solving an equation problem. Seven papers with 50 items each, containing 40 different items and 10 common items, were administered to 3,062 students of Year 6 (Prathom Suksa 6). Ther...
