Here we present the main findings of a study conducted at the Department of Teaching and School Organization of the University of Santiago de Compostela to explore the perceptions of teachers regarding didactic and music materials used and produced to facilitate teaching in early childhood education. This descriptive and interpretative study involved questionnaires sent to a sample of 560 early childhood teachers in public, private, private subsidized, and unitary schools in Galicia. In addition, interviews were conducted to better understand the questionnaire findings. A number of recommendations are included regarding measures to be taken by institutions and professionals involved in the process of design, selection, and use of didactic materials reflecting the analyses and opinions of the teachers in our study. Attention has been given to the comparative analysis of our findings with those in other studies carried out in Galicia and Spain over the past 10 years.
