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. Proprietary conversions of resources from education-related centres such as, zoos, science centres, museums and art galleries, can be created specifically for special needs students and placed online. Small collaborative projects between such organizations, teachers and distance education administrators can target resources that are lacking in the field.
