This issue completes the third part of volume 51, entirely dedicated to research articles in our Miscellaneous section. As in the two previous issues, technology, and its role as a resource and engine of education, continues to have a presence in the published articles. There are also several quantitative and qualitative investigations dedicated to the initial teacher training (either elementary or secondary school) and teachers' professional development. The issue is completed with various works on gender and cultural diversity, as well as democratic and civic education. As it obeys the spirit of Aula Abierta, educational research in any field and of any type, with the sole filter of quality and rigor, is well represented in this issue.
