MariaBegoñaRuizCordero We both, María Begoña Ruiz Cordero and Aníbal Rodríguez Morales, are primary and secondary teachers, as well as university professors. We have completed two degrees at the University of Castilla-La Mancha where we currently work: Teacher Trainning and English Studies. Also, María has a doctorate on Bilingual Education and Aníbal is working on it. Since 2003 till now we have been teaching in different academic levels. Furthermore, we have worked in primary education in a bilingual school in the state of Texas, USA. These facts have given us information to investigate about the development of bilingual programmes in Spain.
