 The
interface was designed for English-speaking non-readers. Lessons are
presented in a suggested cumulative way, but the student is free to
jump around, skip or repeat lessons, just do the tests, never do the
tests. There are no time limits or negative reinforcement.
Navigation is
consistent: the forward arrow always advances one step, double forward
always skips a section. Visual clues show what is clickable: available
navigation buttons light up, suggested navigation buttons are highlighted,
and the arrow cursor changes to a hand over anything clickable.

We
made tests into games, like this slot machine word game, to measure students'
progress in a non-threatening way. |
|
For
spelling lessons, we put a point-and-click, alphabetical-order keyboard
on the screen so the student doesn't have to deal with a QWERTY keyboard.
As the student advances
into more complex interactions, the program provides progressive animated
help.

Contents
are on a lightboard: Each light represents one lesson. When a student
completes a lesson, its light turns off.
We put the contents
at the end of the program, so that every time a student quits the program,
they see how many lessons they have completed. It also lets them to
jump to any lesson by clicking its light.
