A Comparison of Kernel Equating and Item Response Theory Equating Methods

Abstract

In grading, one of the most common errors is made in combining two or more different test scores. This study aimed to investigate the agreement of grades calculated by weighting raw scores and standard scores. Research Methods: In this simulation study, data were simulated for midterm and final measurements. Nine conditions [3 (class level: poor, average, good) x 3 (standard deviation (SD) difference (0, 10, and 20 units)] were considered. The sample size for each measurement was taken as 60 and the replication number set to 100.

Equating of standardized science subjects tests using various methods: which is the most profitable?

“…It is necessary to equalize the test devices used in implementing an evaluation that uses several different test sets and measures the same thing because this equalization ensures justice for test takers. Equalizing scores can be used as a score equalization technique to distinguish bright students from less intelligent students (Akin-Arikan & Gelbal, 2021). Score equalization enables using different test sets for groups based on their ability level.…”
