Visibility of system status

Real time score update

Match between system and the real world

Use user’s language, design cards like real index cards

Correct = green, incorrect = red

Consistency and standards

Standard windows format and color, consistent buttons.

Flexibility and efficiency of use

Can be used for any subject (languages, math, science, music, etc).

Aesthetic and minimalist design

Avoid clutter. Fewest buttons. Big panels.
