Resumen
The aim of this study was to delve into social participation in early childhood education classrooms of centres that include students with ASD, considering social participation as a fundamental element to understand inclusion. To this end, we propose a Convergent Parallel Mixed Methods approach. A quantitative study was carried out with the participation of 85 Early Childhood Education students from centres that include students with ASD. Information was gathered through attitude and social support questionnaires. Six families and eight professionals of these centres participated in the qualitative study. In this case, interviews were conducted. The results show the need to attend to the social participation of all students already in the stage of Early Childhood Education as a fundamental part of what is understood as an inclusive classroom. Similarly, this study identifies both the factors that hinder and facilitate the response of teachers to this aspect in relation to the students, teachers, and families.
