Abstract

This study discusses the role of mathematical literacy as the main competency that cadets need to have in the field of maritime education. Through a systematic literature review (SLR), the mathematical literacy competencies needed by cadets in the maritime field are navigation, problem solving, use of modern technology, operational management, critical and logical thinking, and accurate data-based decision making. This systematic review provides an illustration of literacy mastery Mathematics not only supports cadets' understanding of basic maritime concepts, but also improves cadets' abilities in dealing with challenges or unexpected situations on board ships and while at anchor. Therefore, developing mathematical literacy must be a priority in cadet education and training programs to produce graduates who are competent and ready to face the complexity of the global maritime industry.

Abstract

Mathematical literacy is a crucial competence in maritime education, supporting navigation accuracy, operational efficiency, and safety-related decision-making. However, empirical studies assessing mathematical literacy within authentic maritime vocational contexts remain limited. This study investigates the contextual mathematical literacy of nautical cadets using the PISA proficiency framework embedded in authentic maritime work-related scenarios. A quantitative descriptive design was employed with 23 cadets from a maritime vocational institution. Data were collected through a Contextual Mathematical Literacy Test (CMLT) developed using authentic maritime operational tasks. Descriptive and non-parametric analyses examined proficiency distributions and group differences. The findings indicate that most cadets perform at low to medium proficiency levels, highlighting the need for context-based and PISA-oriented mathematics instruction aligned with professional maritime demands.

Abstract

Shipboard operational decision making requires seafarers to interpret numerical information, identify operational risks, apply procedures, use onboard technology, and coordinate actions under changing conditions. This study evaluated predictive mathematical models of shipboard operational decision-making performance using scenario-based assessment. Data were obtained from 78 experienced seafarers enrolled in Recognition of Prior Learning programs in Nautical Studies and Marine Engineering. Five self-reported constructs were examined: operational data understanding, seafaring experience, SOP and checklist use, shipboard technology utilization, and communication and coordination. The outcome was the mean of four discipline-specific scenario scores. During manuscript revision, all scenario responses were re-evaluated with the predefined 1–5 rubric by discipline-specific subject-matter lecturers, and all analyses were repeated using these expert-assessed scores. OLS with HC3 robust standard errors was used as the inferential baseline, while Ridge regression was assessed using repeated nested stratified five-fold cross-validation. The OLS model yielded R² = 0.198 and adjusted R² = 0.130; X1–X5 were not jointly significant after program adjustment (p = 0.231). The best predictive model, Ridge with X1–X5 and program, achieved mean cross-validated R² = 0.075 (SD = 0.030), RMSE = 1.099, and MAE = 0.950. These findings indicate modest out-of-sample prediction and support cautious use of self-reported operational constructs as predictors of scenario-demonstrated performance.
