Dr. Polat has taught both graduate and undergraduate courses on second/foreign language (L2) learning and teaching, L2 curriculum and assessment, integrated literacy in content areas, and helping minority students (e.g., English learners, Muslim children) in K-12 schools. He is the Program Director of the ESL and TESOL programs. He has published two books and over 20 peer-reviewed journal articles in addition to book chapters, conference proceedings, and critical reviews. He has two research tracks. The first area concerns applied linguistics, particularly L2 learning and teaching while the second area contributes to the field of L2 teacher education. His book entitled "L2 Learning, Teaching and Assessment: A Comprehensible Input Perspective" has been published in Multilingual Matters. His second book, co-authored with Laura Mahalingappa and Terri Rodriguez is entitled "Supporting Muslim Students: A Guide to Understanding the Diverse Issues of Today's Classrooms" and has just been published by Rowman & Littlefield. His work has appeared in numerous and top-tier journals, including Applied Linguistics, Language Learning and Technology, TESOL Quarterly, Modern Language Journal, Journal of Educational Research, Linguistics and Education, Foreign Language Annals, and System. He has been invited to join editorial boards of high impact journals (e.g.,TESOL Quarterly), served as the elected chair of national research groups (e.g., TESOL Applied Linguistics Intersection), and sat on national research and review panels (e.g., Fulbright National Screening Committee, Turkish National Science Foundation, Office of Second Language Acquisition), while also serving as the consulting editor of the Journal of Educational Research and reviewing for almost all major journals in his field.
