Format: Fully Dressed

Fully Dressed

• Scope: Flash Card program
• Level: user-goal
• Primary Actor: Learner
• Stakeholders and Interests:
  • S01 — learns the Malay words and wants only unknown words to come up
  • S02 — wants to see the assignment's behaviour step by step
• Preconditions:
  • A word list exists.
  • A display is available.
• Postconditions (success guarantee):
  • The words the Learner marked as known are no longer in the words to learn.
  • The words to learn are kept, so that the next session starts from them.

Main Success Scenario

1. The Learner starts the program.
2. The system offers the levels: 100 words, 1000 words and all words.
3. The Learner chooses a level.
4. The system loads the words to learn: from the kept progress when it exists, otherwise from the word list.
5. The system shows a random card, with the word in Malay, from the first words of the word list that fit the level and are still to learn.
6. After three seconds the system turns the card over and shows the translation in Danish.
7. The Learner states that the word is known.
8. The system removes the word from the words to learn and keeps the words to learn.
9. The system shows a new random card of the level, and the Learner repeats from step 6 until no word is left at the level.

Extensions (Alternative / Exception Flows)

• 3a. The Learner has given the level when starting the program:
  1. The system skips steps 2 and 3 and goes on at step 4.
• 5a. Spoken words are available on the Learner's machine:
  1. The system speaks the Malay word. If speaking fails, the system logs it and goes on.
• 7a. The Learner states that the word is not known:
  1. The system keeps the word in the words to learn and shows a new random card of the level; the Learner goes on at step 6.
• 7b. The Learner answers before three seconds have passed:
  1. The system cancels the turn-over of the card being shown and starts a new one for the next card.
• 9a. No word is left at the level:
  1. The system tells the Learner that there is nothing left to learn at this level, and further answers change nothing.
• 4a. The kept progress or the word list is unreadable:
  1. The system reports the problem to the Learner and ends; it does not overwrite the kept progress.

Special Requirements / Business Rules

Step	Rule
2, 3	A level is a number of words (100 or 1000) or all words
5	The word list is ordered from the most to the least frequent word; a level of N words is its first N words; a list shorter than N is used whole
5, 9	The next card is chosen at random from the words of the level that are still to learn
6	The turn-over comes three seconds after the card appears
8	A word is identified by its Malay and Danish text; the first equal word is removed; known words stay known at every level and words outside the level are kept
4	The word list names its two languages and holds one word and one translation per card

Open Issues

• Starting again (resetting the kept progress) is not offered in the program; deleting the kept progress does it.
• Going back to the level choice without restarting the program is not offered.
