The IDL instructor's job is a difficult one. They have a tremendous responsibility if a successful class is to result. They must create the illusion of personal interaction with each student even though they might have hundreds in each class. Because no students are allowed in the studio, the instructor has an overwhelming feeling of isolation. To overcome the differences from the classroom, they must utilize the technology that is available to them to create a much more robust learning experience.
Eye contact is critical.
The instructor must remember that all students are in the camera and speak directly to it. The camera exaggerates movement. IDL instructors are required to minimize any movement and usually remain seated during a class. It should only be used to augment the example. Patience - the instructor must be willing to let go control of the class.
