A 30-item pre- and post-test (15 open questions and 15 multiple-choice) was designed in order to exploit the colloquial and informal expressions and words from the episodes. The 15 multiple-choice questions exploited the informal and colloquial words and expressions that appeared in the viewing sessions, containing one correct option and two distracters. The multiple-choice questions were meant to make students recognize and identify the correct item present in a specific scene and context in the episode. A fourth option ‘I don’t know’ was not considered to be included in the test, because students were told explicitly not to choose any option available if they did not know the answer. An example of a multiple-choiceq uestion is the following: The expression ‘to have a blast’ means: a. to be busy; b. to have a great time; c. to have memories about someone
