(i) Know the best films available in your field. | (ii) Know film catalogues and other film sources.
(iii) Observe an effective class room use of films.
(iv) Familiarize yourself with teaching guides.
(v) Learn how to ensure proper physical arrangements in the class-room.
(vi) Learn how to operate a projector.
