Sustainable script and scaffold development for collaboration on varying web content: the S-COL technological approach

We present a single solution for the following two problems: (1) to provide just-in-time support for collaborative learning tasks on top of arbitrary web pages (e. g. in order to foster online search competence) and (2) to transfer collaboration scripts implemented on a particular platform to other platforms. S-COL solves both by using fixed browser-side scripts and scaffolds and triggering them by recognizing types of functionally equivalent web pages, and combines this with collaborative web-browsing.
