In the Diagnostic Stage the researcher collected data on actors’ interests, needs and expectations to validate the pertinence of the project with that population. In the Action stage she designed and implemented a Task-Based English language program to develop language and communicative activities through the use of some specific drama techniques. During the process, she also collected other data by using field notes and a checklist to analyze videos and surveys. After the analysis, the results showed that by following Task Based Learning components and principles, it is possible to build a methodology in which actors gain knowledge of the language while they improve in their acting skills to produce and perform a play for intermediate students and English teachers.
