The problem
Most non-trivial mathematical problems cannot be answered using the conventional QWERTY keyboard. Other programs that offer computer based tasks simply avoid the issue
by making the questions multiple choice, true/false, yes/no etc. Worse, some of them compromise pedagogy by simply not expecting complete answers from students, ignoring issues such as units, indices etc.
Arithmetika neatly solves the problem by giving students pop-up short-cuts to menus full of the necessary characters and symbols. There is one pop-up for each of
- units of measurement
- Rates
- Indices
- Mathematical symbols
- Greek letters
How they work
Students click on an icon to bring up a list of the pop-ups, select the one they want and then click on the required characters. They are automatically added to the answer at the point of insertion and that's that.
