ABSTRACT
A graduate course on visual formalisms for reactive systems emphasized using such languages for not only specification and requirements but also (and predominantly) actual execution. The course presented two programming approaches: an intra-object approach using statecharts and an interobject approach using live sequence charts. Using each approach, students built a small system of their choice and then combined the two systems.
INDEX TERMS
visual formalisms, statecharts, reactive systems, live sequence charts
