Technological training - for a small investment in people (one half to one full days training with the technology) a vast improvement in the use of the technology will be seen. It is critical to deliver such training in advance of course design and development so that the deliverers are aware of the strengths and weaknesses of the medium.
Ongoing training - lecturers can not continue with no teaching in teaching methods, communication skills, organisational and time management skills etc. The success of video conferencing will lie in the people communicating not the technology.
