The integration between service learning and professional courses is seemingly the major teaching objective particularly in techno-vocational based schools. In 2011, fifteen fresh-persons (nine reply the questions) from the English department at Wenzao Ursuline College of Languages went to Lao-lung elementary-and-junior-high-school for nine weeks' English remedial service. In terms of questionnaires, this paper attempts to investigate college fresh-persons' self-growth recognition on English language ability and English pedagogical ability after their service in the remedial classes.The result is twofold:1. Learners are mostly low-proficient in English. Half of the teachers (these fresh-persons) could not recognize the improvement of their English ability after the remedial classes;2. As to the pedagogical item, teachers understand how to use teaching materials and cognize the function of storey-telling. Most teachers feel frustrated in learners' in-class concentration.
