Developing a marine engineering centre of excellence for competency-based training

Institutes imparting training in marine engineering require replication of shipboard ambience for strengthening the competencies. For building an engineering centre for training, five options at different physical levels were considered based on a model of a new liquefied natural gas tanker ship build. A mock-up facility, simulator, full-scale engine room, scaled down version and a combination arrangement with live and dummy equipment were the options. Analytic hierarchy process was applied for selecting a suitable option based on criteria of cost, effectiveness in attaining competencies, practicability and environmental conduciveness. Analyses were carried out on the eigenvalues based on eight subselection criteria. The combination of live equipment (boilers and turbo alternator) and non-live shipboard equipment (auxiliaries) was chosen based on the global weightages obtained from the pairwise comparison matrix computations. The reliability was ascertained from the consistency index which was less than 0.1. For selection of the learning modes and the equipment, a constructivist approach of learners reflecting and choosing the learning mode was adopted. Industry practitioners were made into learner groups composed of trainers, shipboard personnel and company personnel. Established competencies were assigned as scores to the different learning modes. ANOVA application and statistical methods were used to analyse the scores to verify if there were too much variation in the choices. The calculated F ratio values were low (0.14 to 0.40) compared to the reference values indicating that the choices were even. The chi-squared test indicated that the group composition did have an influence on choosing the learning mode and equipment for training. The objective of identifying the learning mode and equipment for the training centre was achieved.     

Improving the validity and reliability of authentic assessment in seafarer education and training: a conceptual and practical framework to enhance resulting assessment outcomes

Past literature on authentic assessment suggests that it provides a far more reliable and valid indicator of outcomes such as higher student engagement, ability to transfer skills to different contexts, multiple evidence of competence, and student performance. This has appeal in seafarer education and training where both students and employers increasingly perceive traditional assessment methods as failing to consistently generate these outcomes. However, this paper argues that improving different aspects of assessment validity and reliability is essentially required to enhance the outcomes identified above. The paper builds on and extends previous work to investigate and develop a conceptual and practical framework that promotes a holistic approach to authentic assessment that provides greater assurances of validity and reliability throughout all stages of assessment within seafarer programs. It also lays the path to future research directions by establishing the agenda to test the practicality of the framework in the authentic assessment of seafarer students and also investigate the impact of students’ perception of increasing authenticity on performance scores in assessment tasks.

Why do marine pollution conventions take so long to enter into force?

A concern of many environmentalists is that marine pollution conventions are usually slow in coming into force. The reasons for this vary with each convention. Instead of exhaustively examining each convention, this paper suggests a general framework of inquiry which may be used in seeking to ascertain the speed and degree of ratification of any particular convention.     

Simulators in bridge operations training and assessment: a systematic review and qualitative synthesis

This article presents a systematic review and qualitative synthesis of the use of simulators in maritime education and training (MET), with a focus on bridge operations during navigation training and assessment. The review found 34 articles published in a wide range of academic journals, displaying a global field of research consisting of three main disciplines: Maritime professionals (n = 15), Human factors (n = 13) and Education (n = 6). An important conclusion made after synthesising the results of the studies is that while the potential of using simulators in training and assessment are clear, little is known about which instructional practices would ensure valid and reliable results of simulator-based education. Since MET institutions train their students for one of the most safety-critical industries in the world, there is a need for empirical studies that explore the use of simulator-based training and assessment further to lay the foundation for an evidence-based educational practice.
