Purpose
Rogo supports mathematical formulas in questions. These are available in the Scenario and Lead-In fields.
You click the button to insert a formula. The equation editor appears in a separate window:
The equation editor supports most formulas, including chemical notations. You can also type in LaTeX command codes such as \sum or \infty to get various symbols. Clicking Insert copies the equation to the field.
You edit existing formulas by simply double clicking on the formula in the field.
General Requirements
To display algebra on screen
Well formed Greek letters (e.g. Times New Roman).
Also well formed English letters, in particular "l" (twelfth letter of Latin alphabet) should look different to "1" (digit between 0 and 2). A looped l may be a necessary addition.
Include options for changing colour for those who need e.g. high contrast.
Font sizes should be suitable for browser commands that enlarge text.
To enter algebra from the button bar (a "palette")
The generally accepted full set of symbols and operations (as found in other equation editors) - see sub-pages.
Students can use equation editor to enter algebraic answers to questions.
Students can enter an algebraic answer AND have a separate box in which to enter "workings" (i.e. several equations showing how they reached the answer) [examiners will be able to see these and award partial marks].
Users can run from keyboard (e.g. via tab and arrow keys).
To enter algebra as LaTeX
LaTeX will allow authors use of all symbols including those not specified through the palette (we do not expect higher level mathematics to be entered through the palette).
For the equation editor to be part of the TinyMCE [the native WYSIWYG editor found in many applications]
