“…Previously, only the real equipment had been used in the laboratory. Some years ago, the courses were only implemented with hypertext tools [11] and in recent years, the universities have been developing some simulation software [7,12,13].…”

Abstract-This paper introduces a new set of compact interactive simulations developed for the constructive learning of computer networks concepts. These simulations, which compose a virtual laboratory implemented as portable Java applets, have been created by combining EJS (Easy Java Simulations) with the KivaNS API. Furthermore, in this work, the skills and motivation level acquired by the students are evaluated and measured when these simulations are combined with Moodle and SCORM (Sharable Content Object Reference Model) documents. This study has been developed to improve and stimulate the autonomous constructive learning in addition to provide timetable flexibility for a Computer Networks subject.

“…• Virtual Labs provide computer based simulations which offer similar views and ways of work to their traditional counterparts (Wannous and Nakano, 2010). Nowadays, simulations have evolved into interactive graphical user interfaces where students can manipulate the experiment parameters and explore its evolution.…”

Traditionally, online control education labs are designed and implemented with the purpose of teaching on a specific topic: controller tuning, stability, etc. These tools usually have a monolithic design: there is a strong binding between the model and the control. Usually, there is a built-in controller that may have a set of modifiable parameters, but the controller itself cannot be changed. Also, it cannot be easily translated to other system, for example to compare the performance. In other words, the system subject of study is not very configurable, which unnecessarily constrains the possibilities of these tools. Though this approach may be adequate for some situations, it would be interesting to have more flexible and versatile online laboratories, for instance, in Master courses, where students are expected to design and test advanced control laws. This paper proposes a new paradigm to develop such tools. An element has been deployed and allows the dynamic execution of scripts written in different programming languages, such as Java, Javascript, or Matlab. The final aim is to provide students with a tool to promote an active participation in the practice, writing their own controller code and freely experimenting with the system. The paradigm is illustrated with some examples of these new generation online laboratories.

“…Virtualization technology has been successfully used to build web-based laboratories for a wide range of online and oncampus ICT courses, Internet Security [1] and Computer Networks [2] for example. In such facilities, the common practice is that learners are served Virtual Machines to work on while completing the practical activities associated with the course.…”

“…In such facilities, the common practice is that learners are served Virtual Machines to work on while completing the practical activities associated with the course. Depending on the approach, either a number of these machines are shared among all learners, or every learner gets a number of them on one host [2]. The size of the laboratory (expressed by the number of the hosts or Virtual Machines) is adjusted according to the requirements of the various activities and the number of participating learners.…”

Web-based laboratories have become so popular in educational institutions for the great benefits these labs bring and ease of use. They have been successfully implemented in a wide range of subjects, but we still need to build training facilities for the uncovered/new branches of learning. In general, the structure of the laboratory varies depending on the subject area; however, in many cases, especially in the case of ICT subjects, it is possible to use the same configurations for more than one course-topic, Networking and Internet Security for example. This means that we only need to create a "prototype" then we can have as many labs as we wish by making "copies" of it. This is not possible with all laboratory-types, but certain technologies make it doable. In this paper, we describe how we used Virtualization Technology (normal and nested) to achieve this successfully. In our system the laboratory components are constructed using Virtual Machines, and then packaged to make one prototype from which we could create a number of labs for different ICT courses.
