Resumen en inglés

The inclusion of ICT in education transforms the way students interact with knowledge, allowing greater collaboration in the classroom and the development of new skills. However, this does not occur in all school contexts, as is the case of the educational institution INEM "Lorenzo María Lleras" in Monteria-Colombia where this research was carried out with the objective of implementing a didactic strategy of collaborative work that allows the development of computational thinking through the application of a collaborative work strategy mediated by the Micro:bit tool with Makecode in ninth grade students. For this purpose, a qualitative methodology was used with an action-research approach that allows the analysis of classroom practices and the application of techniques and resources aimed at improving the training process. The results indicate that the skills of computational thinking, problem solving, critical, logical and mathematical analysis presented improvements, this is attributed to the collaborative work strategy mediated by Micro:bit that proposed roles for the students. In conclusion, ICTmediated collaborative work strengthens computational thinking, participation and improves communication skills, which are necessary for solving complex problems. In addition, it fosters creativity and critical thinking, allowing team members to contribute different perspectives and skills to reach a joint solution.
