Summary
Testing with and without users gave us a
feel for what we had done right and
what we had done wrong
Strengthened our positives
Corrected the negatives using feedback
from testing
Change #1
Problem: No user feedback on what they
answered correctly/incorrectly
Fix: Added “Summary” page at end of level
listing the number and types of problems
answered incorrectly/correctly
Design Principle: Help & Documentation
Change #2
Problem: Support lacking for students who want to
learn and not test themselves or students with
learning disabilities, who need longer time
between bomb drops
Fix: Provide an “untimed” option that lets the user
control the time at which the bomb drops
Design Principle(s): Universal usability, User
control & freedom
Change #3
Problem: Lack of color made it less lively and less
like a computer game
Fix: Added more color to the game and made the
characters more expressive, with emotions
Design Principle: Aesthetic and minimalist design
Change #4
Problem: Lack of documentation on what
the trash option meant
Fix: Added an instruction side before the
game play screen start that told the user
what it meant
Design Principle: Help and Documentation
Positives
- The users enjoyed the aesthetic style of the
-
game: characters, vehicles, layout, etc.
(Aesthetic and minimalist design)
They understood most aspects of the game
without going through the tutorial (Consistency
and Standards
They enjoyed the ability to choose their
characters and vehicle (User control and
freedom)
