In developing SCORE materials we rely on JSXGraph . It is a cross-browser library from Bayreuth University which is implemented completely in JavaScript. JSXGraph supports multi-touch devices running iOS, Android, firefoxOS, Windows 8 (at least). One of the main aims of SCORE project is to use it to create hands-on animations with a “didactical” view and including feedback.
JSXGraph Examples:Drag the points to show that the liquid is more dense than water.
