This study examines the outcomes of a two-part service learning project in a summer practicum for English as Second Language (ESL) teacher endorsement candidates. First, 10 mainstream K12 teachers with 2 to 30 years' experience needed practice teaching students with linguistic and cultural differences. Their own service learning was to implement a summer family literacy program for ESL students. Second, these teachers had planned a service learning component for the ESL students. Teachers, feeling obliged to correct all the perceived linguistic deficits in students, went into a panic that they described as "emergency room mode." Regarding service learning and any other non-classroom activity as distraction, they chose to have ESL students abandon such activities. Teachers did gain significantly in understanding and implementing concepts studied in university classes, but their conclusions about service learning varied.
