Pose multiple choice questions. Initiate opinion polls. Receive information on trainees who have indicated failure to understand the lesson. The control screen image can be presented to students during the broadcast if the trainer so wishes. Integration of the various media, the best trainer and the most advanced technology produces the best possible presentation, lesson or training session.
Participants can pose and answer questions, have discussions and make comments or observations.
The dialogue may be initiated either by the student asking to speak, or by the presenter calling on a specific student. Data communication allows for immediate feedback from all students regarding questions raised by the trainer. Such questions may either test the students' knowledge and understanding or request opinions and evaluations. Replies can be stored on a central database for susequent analysis. It is this interaction between the presenter and the students or trainees which turns the broadcast into a truly live session, just like a conventional classroom lesson and in certain ways even better.
