Herron (1994, pp. 775-795) studied American university students of French and compared video and text-based materials. An experiment was conducted in which the control group was taught with a text while “semi-authentic” videos were used to teach the experimental group. These videos were an “on-going drama in which native speakers interact in authentic situations”. The “drama” was created specifically for language learners but the videos also included clips from French films and television advertisements which added a measure of authenticity. The experimental group’s scores in listening comprehension showed significant improvement over those of the control group.
