  • UNED, the Spanish University for Distance Education, is the only

state-run Spanish distance-learning university and it is the largest university in Spain.

  • One of the largest European Universities with around 220,000

students, most of them adult students, and near 1,500 teachers. – Central organization: Madrid – 65 study centers: All over Spain – 13 study centers in Europe & America

  • UNED focuses mainly on distance learning and continuous education.
  • It delivers degrees in most disciplines

including Industrial Engineering, Computer Science, Physics, Chemistry, Mathematics, Economis, Social and Political studies, Humanities, Arts ….

  • UNED’s teaching methodology incorporates intensive and extensive

use of e-learning resources including interactive video lectures, remote and virtual labs, e-learning platforms, learning objects, augmented reality, mobile devices, and biometrics.

  • EjsS

is a free open-source tool developed in Java/Javascript designed for the creation

  • f

computer simulations.

  • EJsS has grown to help in creating web-accessible

(virtual and remote) laboratories:

– Connections with external applications. – New features for 3D modeling. – New libraries and plug-ins to improve the development of VRLs – New experiment languages. – Etc,…

Easy Java/Javascript Simulations (EjsS)

EjsS provides a simplified implementation of the Model-Control-View paradigm.

  • 1. The model, which describes the phenomenon under study
  • 2. The control, which defines certain actions that a user

can perform on the simulation

  • 3. The view, which shows a graphical representation of the

different states that the phenomenon can have. Control Model View

  • Virtual/remote

experimentation is a mature technology.

  • Yet, it is not easy to transform a traditional lab

into a web-based lab.

  • More research has to be done in providing new

tools and new facilities.

  • We have presented our approach using:

– Easy Java Simulations to develop the interactive GUIs. – LabView and Matlab to develop the real-time control loop at the server-side. – Moodle to deploy the web-based/remote labs.

  • Last

course was the fourteenth year
