eXtremely simple scripting (XSS): a framework to speed up the development of computer-supported collaboration scripts

External computer-supported collaboration scripts may support learners in collaboratively using new technologies. This contribution introduces a framework that offers an object-oriented package of classes and methods that supports eXtremely Simple Scripting (XSS), i.e., the rapid implementation of CSCL scripts for the use with new technologies. We report two examples on how this framework has been used to implement computer-supported collaboration scripts in mobile learning with tablet-PCs and with an interactive table.
