E-learning systems have evolved moving from self-contained simple static contents, to the design and execution of learning scenarios described by educational modelling languages (EML) and the integration of Web services. But also carrying with implications such as dealing with long-lived learning activities and finishing activities without accomplishing their learning objectives. Advanced transactional...
Educational Modelling Languages such as IMS LD, LAMS and LPCEL can be used to describe a learning process, but they depict different degrees of expressiveness to represent learning flows. This paper presents an evaluation of the expressiveness of these languages based over the analysis of different workflow control patterns including basic control flow, advanced branching and synchronization, and...
Cyberworlds could be a platform for both research and e-learning particularly in research intensive disciplines such as biology, physical chemistry, molecular medicine, biophysics, structural biology, bioinformatics, etc. The computer simulation of assembling molecules has been studied intensively in the field of computer-aided rational drug design. The assembly of molecules in a three-dimensional...
Educational Modeling Languages (EML) are currently used to design and specify complex learning process that adapt the demands of a particular learning setting. LPCEL (Learning Process Composition and Execution Language) is a formal language used to specify complex learning scenarios. From a software architectural point-of-view, a service-oriented architecture (SOA) provide an important approach in...
It is not always possible to foresee all properties values of a learning design process at design-time. Sometimes, it is not until its proper execution when those values can be established. Besides, some of the original definitions must be modified to adapt the learning process to its current execution context. This is especially necessary with properties related to the synchronization and temporization...
Collaborative learning is attracting increase attention as a methodology to simultaneously improve motivation and interactivity. In order to fully enhance its potentialities, appropriate technological platforms and academic experimentation are needed. In this paper, a master course level experiment is presented based on the learning infrastructure defined
