Developing Two Equivalent Spatial Ability Tests for Myanmar Middle School Students

Abstract

Nowadays, interest in spatial ability has been increasing in education because it can predict education and professional success. However, in Myanmar, there was no wide awareness of the importance of spatial ability, and there were no typical spatial ability tests. Therefore, in this paper, two new equivalent multiple-task spatial ability tests were developed. These tests were designed as multiple-task spatial ability tests to measure more aspects of spatial ability than single-task tests. To develop the tests, a two-parameter logistic model (2PLM) of item response theory (IRT) was utilized. Consequently, two equivalent tests composed of 40 items were developed.
