Instructional Simulation

An instructional simulation, also called an educational simulation, is a simulation of some type of reality (system or environment) but which also includes instructional elements that help a learner explore, navigate or obtain more information about that system or environment that cannot generally be acquired from mere experimentation. Instructional simulations are typically goal oriented and focus learners on specific facts, concepts, or applications of the system or environment. Today, most universities make lifelong learning possible by offering a virtual learning environment (VLE). Not only can users access learning at different times in their lives, but they can also immerse themselves in learning without physically moving to a learning facility, or interact face to face with an instructor in real time. Such VLEs vary widely in interactivity and scope. For example, there are virtual classes, virtual labs, virtual programs, virtual library, virtual training, etc. Researchers have classified VLE in 4 types:

• 1st generation VLE: They originated in 1992, and provided the first on line course opportunities. They consisted in a collection of learning materials, discussion forums, testing and e-mail systems all accessible on line. This type of virtual environment was static, and did not allow for interaction among the different components of the system.
• 2nd generation VLE: Originated in 1996, these VLE are more powerful, both in data base integration and functions - planning and administrating, creating and supporting teaching materials, testing and analyzing results. Over 80 forms exist, including Learning Space, WebCT, Top Class, COSE, Blackboard, etc.
• 3rd generation VLE: The novelty of 3rd generation VLE is that they incorporate the newest technologies, accessible in real and non real time (synchronous and synchronous communications), such as audio and video conferences through the internet -‘one to one’ and ‘one to many’, collaboration features for work in groups, seminars, labs, forums, and of course the learning, development, planning, library and administrative functions. Stanford On-line, InterLabs, Classroom 2000 and the system "Virtual University" (VU) are examples of this VLE.
• 4th generation VLE: These are the environments of the future, and represent new learning paradigms, at the center of which are the user and the ‘global resources,’ as opposed to the teacher and the ‘local resources.’ Their main advantage is that learning materials can be created, adapted and personalized to the specific needs and function of each user. Few 4th generations VLE exist, most of them still being in the planning and developing phases. One example of supportive technology is called the ‘multi-agent technology,’ which allows the interface of data among different systems.
