Online learning, also referred to as Web-based learning, is learning that takes place via a computer connected to the Internet. Typically the learner logs into a system and accesses information from an instructor or tutorial. The learner then follows an established sequence. At each step the learner interacts with the computer to access more information or supporting resources from the Internet. In the web environment lessons can require readings (posted on web pages, downloadable files) or interacting with web-based software applications that may allow viewing of demonstrations, assessments, and simulated cases. Asynchronous or live chat can also be incorporated providing interaction with the instructor or other learners. These interactions giving the learner the feeling of belonging to a class or cohort. Audio, video (compressed), text, and graphics can all be used to display the information, training, or lessons. Since web-based learning can incorporate the vast resources of the Internet, there is almost limitless potential for enhancement. Some of the resources that can be incorporated are access to journals or their abstracts, links to related web sites or blogs, downloading of files and information, and participating or observing listsev discussions or forums. Depending on the resources available, the initial design and objectives, and how the instruction is structured, web-based learning may be highly interactive. In fact, from my personal experience, interaction improves the course as learners are social being and need an affective dimension to their learning experience. The cohesion and the kinds of relationships that form in this kind of enviroment are remarkable and worth of more study.
