It provides the flexibility in content, time, duration, pace, place of study and also strategy for study. The computers and communications offers unprecedented opportunities to the technical and vocational education system with its capacity to integrate and interact with each other over a wide geographic distance in a meaningful way to achieve the instructional objectives. The growth of these communication and computer system, their ease of use, the power diversity of information transfer allow teachers and students to have access to a world beyond the classroom and have the potential to change the nature and process of the learning environment. But most of the network based learning package currently available confined themselves to the domain of information transfer. Little interactive course ware is available except for hyper media jumps.
Much enthusiasm tends to confuse learning with access to information.
To make the learning more individualized, more active and enjoyable there is an urgent necessity to develop highly interactive multimedia based software under the change environment of Network Based Learning. It should be always kept in mind that no matter how sophisticated the technology is, it is the individual who decides when, how why they learn. While these methodologies have received general acceptance, the learning theory pendulum have swung from automatic and machine like to ultra dynamic process and the researchers are yet to find a theoretical common ground. From a neurophysiolocal perspective, the acquisition of knowledge is preordained and takes place by selection from existing neuronal circuitry i.e., the brain development proceeds according to the genetic plan. An empiricist ensues that environmental interactions lead to irreversible changes in dendritic branching and synaptic formation in the brain.
