Resumen: The increasing need to train bilingual students has brought about a shift in English teaching methodology, bringing students’ motivation to the forefront. This paper presents a multiple case study conducted with a group of students in year 6 of Primary Education in Spain, who have been identified as highly motivated towards learning a second language (L2 motivation). The purpose of this research is to examine which factors most significantly impact students’ L2 motivation, as well as how are those factors are cultivated in the classroom context. Despite the limitations of our study, it is noted that there are several factors in the classroom context that substantially influence some constituents of learners’ motivation. From the conclusions drawn, I make specific didactic suggestions may be useful for Primary Education English teachers and which may be applicable to similar contexts.
