After teaching English to Korean missionaries and observing their struggles due to the language barrier in the Philippines, Chang Hoon dedicated his life to teaching English to prospective missionaries. He earned a Doctor of Education degree from Temple University in 2007, with a concentration in TESOL (Teaching English to Speakers of Other Languages). He has served as a “cultural mediator” creating a culturally sensitive classroom and culturally diverse curriculum, so that students can be prepared to competently participate in an increasingly intercultural society. Chang Hoon taught at Temple University, Arcadia University, and Geneva College at the Center for Urban Theological Studies before coming to Missio (then Biblical Theological Seminary) in 2010. He resides with his wife, Hee Young, who was a teacher in Korea, and a son, Min Hyoung, in North Wales, PA.
