“…Sistematic observation allows studying interactive behaviors in an objective way and in its natural context (Anguera, 1990;Sánchez-Algarra & Anguera, 2013) and it has been widely used in the educational context (Borges & Rodríguez-Dorta, 2015;Díaz, Borges, Valadez, & Zambrano, 2015;Rodríguez-Naverias & Borges, 2015).
