The transfer and sharing of successful educational methods across countries is viewed as both an opportunity and a challenge. The opportunity is to benefit from the successful experiences of other educational systems. The challenge is how to transfer and adapt such educational methods. This paper proposes open source software a concrete transfer method of educational experiences. This approach is illustrated with an example learning management system originally built in Finland and recently made open source for Tunisian universities as a primary target.

The abstract syntax of a graphical modeling language is often defined by a metamodel. Typically, a metamodel is given as a class diagram, serving as the grammar of the modeling language. Especially in the case of complex metamodels, there is a need for tool support for assisting the creation ofmodels. In this paper, we propose a method for taskdriven creation of models, assuming that the metamodel has been given as a UML class diagram.

We introduce a specification technique that uses a combination of statechart templates and structural models for deriving spoken command languages for the domains specified by the structural models. We apply the technique for the domain of UML editing.

The Unified Modeling Language (UML) provides several diagram types, viewing a system from different perspectives. In this research, we exploit the logical relationships between different UML models. We propose operations to compare, merge, slice and synthesize UML diagrams based on these relationships. In a formal demonstration, we show how statechart diagrams can be synthesized semi-automatically from a set of sequence diagrams using an interactive algorithm called MAS. We also demonstrate how a class diagram, annotated with pseudocode presentations of key operations, can be synthesized from sequence diagrams, and how class diagrams and sequence diagrams can be sliced against each other.
