Tsai Pei Jin, a teacher at Chien-Long Elementary School in Taoyuan County, is one of the winners of a competition for non-native English-speaking teachers, the organizer, Cambridge University in Britain, announced Wednesday. Tsai, along with four teachers from Argentina, Vietnam, Kazakhstan and Poland, respectively, won this year's English for Speakers of Other Languages (ESOL) competition, the university's ESOL office in Taipei said. Some 2,000 teachers entered this year's competition, which required each contestant to submit a 150-word essay describing how Cambridge courses would benefit them and their students in English learning. The five winners will be invited to attend a teacher development program at Cambridge University's Homerton College in July.
