The Matriculation Examination Board in Finland has created an usb stick based exam system (Abitti) where all exams are done digitally
Basicly it is an offline exam system but teachers can create and grade "course exams" online and most of the GPL tools can be practised online.
I would like to test adding some of these tools to moodle for two reasons:
1) to make testing and practising our national exam tools easier for students with help of tools of moodle - especially the "math tools"
2) to give some new tools for Mathematics, Physics and Chemistry teachers in moodle
The first step might be to test adding the abitti math editor to moodle. You might be able to use it in the future
a) to create editable svg images to moodle with normal editor buttons of Atto or TinyMCE (or CKEditor)
b) to use it as an optional editor like Atto
c) to use it in some new question types similar to Wiris question types
Source of the GPL editor is here https://github.com/digabi/rich-text-editor ,
example code in https://github.com/digabi/rich-text-editor/blob/master/index.html and a working online demo in http://digabi.github.io/rich-text-editor/
or https://math-demo.abitti.fi/ In this demo editor "Lisää kaava" means "Add a formula".
Because the editor is using two "math engines" - MathJax and MathQuill - it is not fully cross browser compatible (MathQuill has some problems in mobiles)
What do you think? Is this worth testing in moodle or a too big challenge?
