Teaching based on active methodologies emphasizes the importance of giving students a leading role in the learning process. With the implementation of the European Higher Education Area, universities have undergone a reform that significantly increased student involvement in the teaching-learning process. The University of the Basque Country (UPV/EHU) responded to this change by introducing its own educational model: IKD i[superscript 3]. The general objective of this research is to explore the effect of the IKD i[superscript 3] strategy on the teaching staff of the UPV/EHU. The study aims to identify the active methodologies adopted by the teaching staff and the reasons behind the use (or not) of these methodologies. A total of 403 teachers participated in the study, and their opinions were gathered freely to accurately represent their viewpoints. The results reveal that teaching staff at the UPV/EHU utilize active methodologies, with the most frequent being problem-based learning, cooperative learning, and the case study method. The reasons for incorporating these methodologies vary and include both benefits for students and advantages related to teaching, while the rationale for not using active methodologies is based on the lack of training, time constraints, and having a large number of students. Interestingly, the teachers who expressed these arguments were primarily those who were not familiar with or actively participating in the IKD i[superscript 3] educational model. We believe that while our findings validate the UPV/EHU's IKD i[superscript 3] educational model, they also highlight the importance of universities not only having an educational model but also fostering a culture that encourages the active engagement of teaching staff. This commitment is essential to effectively develop and implement such a model.
