Objective | Reason Why | Action required | |
Cadet Training & Modernisation Working Group | Include Human Element Factors throughout the syllabus | To provide seafarers with a contextualised understanding of the Human Element in the maritime industry, showing how they can put theory into practice in the work they carry out at sea. | Raise awareness throughout the Cadet’s training of the areas in which human element factors will have an impact. Recommendations on where this can be included have been noted throughout the entire syllabus. Not every template has Human Element Factor recommendations but please do add any you feel may have been missed. |
Cadet Training & Modernisation Working Group | Include Data Science skills throughout the syllabus | Data Science Skills (Comprehension, Analysis, Presentation, etc…) are already required within much of the syllabus. A further, specific focus on these skills needs to be taught where relevant. | A specific topic will need to be introduced to improve Cadets’ Data Science skills. Practical application of data science skills should be highlighted throughout the syllabus. Not every template has Data Science recommendations but please do add any you feel may have been missed. |
Cadet Training & Modernisation Working Group | Ensure all outcomes are contextualised to help Cadets understand what they are learning in relation to what they will experience at sea. | While some outcomes are intrinsically linked to work carried out at sea, some need to be contextualised to show how they apply to work on board. Where this is the case, it is important to make sure Cadets clearly understand how the outcome relates to work at sea and it is essential to make sure that this context is given with reference to current and future seagoing technologies and practices. | Where outcomes do not specifically cover a topic which relates to work carried out at sea, more must be done to contextualise the outcome and make it relevant to the maritime industry, giving specific shipping examples of how the outcome may be applied in a modern shipping context. Not every template has contextualisation recommendations but please do add any you feel may have been missed. |
