Abstract

This chapter introduces a new visual Educational Modeling Language (EML) based on a separation-of-concerns approach, PoEML: Perspective-oriented EML. EMLs were proposed to support the modeling of educational units. These languages are related to ID, as they are intended to represent models of educational units. This chapter introduces the PoEML separation of concerns and its graphic constructs. The main idea underlying PoEML is to break down the modeling of educational units into separate parts that can be specified independently. PoEML is mainly focused on supporting the computational execution of educational unit models. In addition, the separation of concerns allows us to approach the modeling of educational units in an incremental way, offering advantages in expressiveness, formality, adaptability and flexibility.
