Gender perspective is still a sensitive issue in the society of the 21st century. Education seems to be the best way of making people realise that we are all equal, no matter what our gender, sex or beliefs are. The aim of this research paper is to carry out a case study to uncover the reality of this topic in a high school in Lleida, and more specifically, in the English classroom. My hypothesis is that there is a lack of gender perspective in English classrooms and that gender awareness can be enhanced while learning English. An online survey to all the teachers of English and to all 2nd Batxillerat students in the high school, together with an interview to their English teacher and an analysis of a unit in their textbook were used to collect data about how gender perspective is dealt with in a public secondary school in the city of Lleida. The results of the analysis indicated that even if participants were aware of the importance of gender diversity, materials and language show a bias towards stereotypes which, in my opinion, should be avoided. A gamification unit to be implemented in the English class was also designed to deal with the topic and, ultimately, to be used as a model for further learning experiences.
