IMS Learning Design (LD) is a specification that aims at computationally representing any learning process. However, the possibilities of LD to represent collaborative learning scenarios are being questioned by the Computer-Supported Collaborative Learning (CSCL) community. In this paper we analyze the LD support to realize CSCL macro-scripts, which describe flows of coarse-grained activities. We first identify the requirements of the scripts for their representation using LD and, then, study the possibilities of LD to support each of these needs by means of two significant scripts that representatively feature the requirements. The paper indicates the conclusions from this analysis showing the capacity of LD notation to express CSCL macroscripts but also considering the support of related specifications and tools.
