This research examines the impact of field experiences with English language learners on the conceptual and emotional development of preservice disciplinary students. For one semester, preservice university students worked with English language learners enrolled in middle and high school Newcomer Programs. During this time the university students wrote reflection papers and grand learnings/lingering questions essays linking the field experiences with course readings and in-class activities. A qualitative analysis of these reflections found four critical content-based learnings related to English Language Learners emerged from these field experiences: (1) the distinction between content, language, and activity challenges; (2) conversational versus academic language; (3) code switching with the use of the home language in the classroom; and (4) increased confidence, empathy, and advocacy of the preservice teachers for English language learners. Suggestions for those instructors wishing to provide similar experiences to their preservice students conclude the research.
