This article is the result of an investigation into the implementation of role-playing in the classroom as a technique to improve oral production in a foreign language with 20 sixth-grade students from an educational institution in Nariño. A field diary and a SWOT matrix were used, following a qualitative paradigm with a socio-critical approach. The general objective was to strengthen oral production in a foreign language using the role-play technique. The data analysis was carried out by emptying the information and extracting the categories and subcategories. It was found that the sixth-grade students did not have the level of English required by the Ministry of Education. Therefore, the role-playing technique was used as a strategy to improve their ability to express themselves in English as a foreign language because it is a way to increase their vocabulary, organize sentences, imagine, and represent characters.
