About Maritime Academy
The app teaches maritime flag signalling (generally flaghoist signalling), which is the principal means other than radio by which ships communicate to each other or to shore.
Virtually all signalling by non-naval vessels is now organized under the International Code of Signals (whether by flaghoist, semaphore, signal lamp, or other means), which specifies a standard set of flags and codes and is the most recent evolution of a wide variety of maritime flag signalling systems. Naval vessels generally use an extended set of flags and their own codes.
--------
Teaching method
The two key teaching and training concepts are progressive introduction and focused repetition. The learning material is categorized into chapters and then broken down into manageable units (levels) to ensure efficient learning and training.
--------
Learning material
In general, the learning progresses from single-flag content to multi-flag content. That is to say, from letters & numbers to words & substitutes, and then to single flag meanings & abbreviations. The content is arranged for optimal efficiency and we strongly recommend you to go through the levels in this order.
- Letters (8 levels + 4 challenges)
- Numbers (3 levels + 1 challenge)
- Words (30 levels)
- Substitutes (1 level)
- Single Flag Meanings (8 levels + 4 challenges)
- Abbreviations (54 levels + 26 challenges)
--------
Levels and challenges
In short, a level focuses on introducing and training new letters/numbers/abbreviations, while a challenge tests what you’ve learnt. In the learning screen, the knowledge you should focus on is highlighted and in the training screen, you will practice by answering a few questions (like a quiz game). In a challenge, you must make less than 3 mistakes to pass it.
--------
Training types
There are three training types, that is to say, key, typing and button.
