At the 2012 TESOL International Convention & English Language Expo in Philadelphia, Keith Folse was presented with the National Geographic Learning 2012 Heinle Outstanding Achievement Award. This award is given at the annual TESOL (Teaching English to Speakers of Other Languages) conference to a National Geographic author who has made a major contribution to the field.
As the largest organization focused exclusively on English language teaching for speakers of other languages, TESOL annually hosts more than 6,500 people from across the United States and around the world at the international convention.
Folse is the author of 56 monographs and textbooks and is a frequently invited plenary speaker at TESOL conferences worldwide, most recently at TESOL Arabia and Korea TESOL. In May, he will be speaking in Mexico and Peru.
