Real time web based videoconferencing, audio conferencing, collaborative work areas, chat rooms or IRC, messaging boards and email can all be used for creating interactive learning environments. New web technologies are constantly being introduced into the market. However, each technology should be justified in terms of cost, target audience and accessibility before implementing them within a distance education program. For example, a teacher discussion forum about an article on ADHD can occur either through web-based videoconferencing or email. The former requires tight scheduling as well as a video capture card, a camera, and adequate Internet bandwidth for each participant.
Issues involving moderation, time zone discrepancies and access can arise with video conferencing.
E-mail discussions however have no special hardware requirements, have few or no access problems and can occur asynchronously. Participants can compose their thoughts and replies with as much time as required. Each method has its advantages and disadvantages, but both allow interactivity among peers. Generally, there is a need for enticing, current curriculum for special needs students and teachers. It is essential that curriculum is motivational so that student will want to learn.
