This paper examines classroom interactions and their impact on English as a Second Language (ESL) students' motivation in a 6th-grade class in Galicia, Spain. Using linguistic ethnography and intercultural contact theory, the analysis explores how teacher-student interactions, home influence, and access to ESL resources affect language learning outcomes. Findings suggest that intercultural experiences and motivational factors foster successful ESL acquisition, while limited opportunities for such exchanges may hinder progress. Recommendations for improving ESL environments through increased resources and intercultural engagement are provided.
