The following report shows the internship experiences that took place in the Bilingualism for Peace Program at the moment of teaching 28 students from Pre-intermediate level aging 11 to 13 years old in a public school in Monteria, Cordoba. The goal of this internship was to implement collaborative learning work as well as strategies for English classes in order to promote a positive and inclusive classroom environment. This was done integrating Problem-Based-Learning (PBL) and Team-Based-Learning (TBL) as pedagogical strategies. The results showed improvements in student’s attitude towards collaborative work, leading into a more active and participative classroom space where all students’ voices were heard and accepted.
