Sustainable Development Goal (SDG) 5 “Gender Equality” aims to achieve gender equality and empower all women and girls. Gender equality is not only a fundamental human right but also one of the essential foundations for building a peaceful, prosperous, and sustainable world. While some progress has been made in this regard in recent decades, many barriers still remain. This chapter presents an experience designed to give visibility to women professors and researchers at the University of Salamanca (USAL) through Wikipedia (the free encyclopedia). It has been proposed as Learning Situations for different subjects in the specialties of Technology and Physics and Chemistry through a thesis project for the master’s degree in Compulsory Secondary Education, Baccalaureate, Vocational Training and Language Teaching (MUPES, by its acronym in Spanish). It is clear that in order to change society’s view of women, the role of education is fundamental, and in this sense, we must start by training the future teachers such as MUPES students, who thus will become agents of change. One of the targets of SDG 5 is to “Ensure women’s full and effective participation and equal opportunities for leadership at all levels of decision-making in political, economic and public life”. To achieve this, it is essential that school-age girls are provided with role models of women who have developed their professional lives in the world of research. However, it is not only important for girls to have these references, but also for boys to normalize the fact that there are women carrying out cutting-edge research work, to eliminate the existing gender bias that exist in the fields of Science, Technology, Engineering, and Mathematics (STEM). This work presents the different developed phases of the Learning Situation: (1) the training of university students in the Wikipedia editing process, enabling them to act as editors; (2) the process of interviewing female research professors about whom they wanted to write a biography; and (3) the incorporation of the entries in Wikipedia once they have managed to become editors. The objective is to follow the initiative launched by Wikipedia in November 2021, focus on promoting entries dedicated to women scientists and technologists, thus contributing to reducing gender biases.
