Working toward an international assessment of ocean literacy: Validating instrument with Rasch measurement model

• This study is part of a larger multinational effort to construct an international assessment of ocean literacy. This work examines the psychometric properties of the English version of the most recently developed International Ocean Literacy Survey (Version 4) using the Rasch measurement framework. The goal is to establish that the set of items that have passed expert review on item design and alignment with the ocean literacy principles also meet the strict standards of psychometric analysis. Psychometric studies including, reliability and unidimensionality, item analysis, and differential item functioning (DIF) are performed to evaluate the measurement quality.
