A crucial challenge for improving EMLs is to provide an intuitive notation to support educational practitioners to not only understand, but also describe a large number of flexible scenarios themselves. We present here the general outline of a graphical modeling language based on the concept of Learning Activity Space (LAS) and its related editor so-called SCY-SE. The design stage of learning computersupported scenarios can be facilitated by the use of LAS arrangements as improved in the context of an interdisciplinary European project named SCY (Science Created by You).
