Complex learning scenarios are represented using Educational Modeling Languages (EMLs). Different people with specific skills usually design these scenarios. The IMS LD is a commonly used EML for which some visual editors are being created in order to assist the authoring process. However, these editors have a limited level of expressiveness and do not provide the facilities for designers to collaborate in the design process. The LPCEL Editor provides a broad level of expressiveness and facilitates the authoring process with an editor that includes: (1) Visual Elements, (2) Intermediate Representation, (3) Learning Patterns, (4) Collaboration tools and (5) Web Services. In order to verify that the components are sufficient, we conducted a user evaluation to analyze their perspective regarding the level of functionality of the tools.
