After watching a movie one time, replay that movie with the closed captioning (CC) on, and the volume set on mute. Pick a student and ask them to read the closed captions aloud as the movie plays. Be sure to pick a different student after every few lines of dialogue. In addition to reinforcing the lesson of the movie, reading aloud helps you to check students’ pronunciation, and the students themselves will be made more aware of  errors they might have been making.
