This dissertation was carried out following an investigative model of an applied and qualitative nature in which it was observed, intervened and analyzed a real context, Sinapsis Foundation. This investigation has as its main objective to design an inclusive intervention proposal for teaching English at Sinapsis Foundation. Moreover, it seeks to contribute to the development of teaching strategies in order to encourage other language teachers to research and teach in inclusive contexts, bearing in mind six criteria that facilitate inclusive education: context and culture of the center, relations with families, educational project of the center, curriculum proposal, classroom work and teaching staff. Furthermore, the case study was chosen to analyze the implications of teaching English in a context such as Sinapsis Foundation. All the participants involved belong to the Foundation’s community, including board of directors, team of teachers, students and students’ relatives. The case study was divided into three phases: call, the students were invited to participate in the classes; conformation of the group, it was determined which and how many students would participate and planning, the contents and activities to work in class were planned. Field notes were used to record all the data obtained and to demonstrate the results of the inclusive intervention proposal and its implications. Finally, three members of the Foundation were interviewed for the purpose of knowing their point of view about the work done there; for this, the semi-structured interview was used. Among the results, three of them stand out. First, a specific method and/or approach cannot be followed since the necessities of these students are different; in addition, elaborating lesson plans turns out to be one of the foundations of teaching. Secondly, a person with disabilities can learn basic aspects of English by means of the correct direction of the activities and the use of adapted material which promotes multisensorial aspects that ease learning. Lastly, gamification played an important role in the development of each class as an element that motivated students to continue learning.
