Ideally, instructors should have formal training on these strategies. Before teaching an ITV course class for the first time, it would be advantageous for instructors to have taught the course first in the traditional format. Instructors and facilitators are enthusiastic about the experience of teaching through ITV, and about its potential to enhance the educational experience of learners. Students at remote sites especially appreciate the availability of courses, instructors and specialists not normally available. This is a source of satisfaction for remote site students, even if little student interaction is employed.
Academic achievement is similar for host and remote site students.
Courses with a significant practical component can be taught through ITV if remote site students have timely access both to the relevant materials, and to any hands-on instruction that may be necessary. Audio clarity is critical to courses being well received, especially for classes that emphasize student interaction. This needs to continue to be a priority in terms of technical equipment and support. Meaningful student interaction in the ITV classroom is affected by class size. Courses with significant levels of student participation should have predetermined enrolment and sufficient numbers of microphones.
