Yuko Goto Butler is Associate Professor of Language and Literacy in Education at the
Graduate School of Education at the University of Pennsylvania. Her research interests
are primarily associated with the improvement of second and foreign language education
among young learners in the U.S. as well as in Asia in response to the diverse needs of
an increasingly global world. Dr. Butler has been interested in identifying effective
ESL/EFL teaching and learning methods and strategies that take into account the relevant
linguistic and cultural contexts in which instruction takes place. She is also interested
in how we can effectively assess children’s second/foreign language proficiency and how
best to evaluate the effectiveness of various programs and policies for language
education. Her most recent project examines various issues that have arisen in
conjunction with the introduction of English language instruction at the elementary
school level in select Asian countries.
