This article examines the teaching of English as a Second Language (ESL) to medical personnel (nurses and doctors) in a hospital in Northern Thailand. The study shows that using technological devices like listening and comprehension CDs, tape recorders and the Internet to teach informational texts can help ESL learners overcome some of their learning difficulties. Evidence from the study suggests that such a pedagogical approach not only improves the comprehension of informational texts but also students' mastery levels of spoken and written English. The findings also reveal that such a pedagogical approach exposes students to the various nuances and differences associated with Global English awareness and understanding.
