Recently, Pierre Tchounikine challenged (https://link.springer.com/article/10.1007/s11412-016-9240-8) the Script Theory of Guidance. He argued to consider appropriation of external collaboration scripts, i.e. how learners interpret externally provided collaboration scripts, in SToG.
Pierre’s paper as well as our (Karsten Stegmann, Ingo Kollar, Armin Weinberger, Frank Fischer) reply (https://link.springer.com/article/10.1007/s11412-016-9241-7) are now available at the ijCSCL’s homepage at Springer (http://link.springer.com/journal/11412).
