Likewise, Roth and Dr. Teresa X. Nguyen co-authored Compelling Conversations- Vietnam: Speaking Exercises for Vietnamese Learners of English (2017), turning a previous EFL textbook into a niche ESL textbook. Further supporting busy educators, Roth and Nguyen also wrote Creating Compelling Conversations: Reproducible Search and Share Activities for English Teachers (2019), offering quality supplement materials for highly-motivated students.
Roth’s professional path demonstrates a deep commitment to curriculum leadership and international education. He taught writing to University of Southern California (USC) engineering students in Madrid, Spain in 2007 and Paris, France in 2008. The following summer, Roth directed the APU International High School program in Ho Chi Minh City, Vietnam. USC promoted him to Master Lecturer in 2013, recognizing his sustained contributions to English language education and intercultural communication. From 2015 to 2017, he served on the Fulbright English Teaching Assistant national selection committee. Roth has served as a faculty advisor to USC Fulbright ETA applicants since 2012.
As an ELT speaker, Roth has become a frequent and grounded voice at CATESOL conferences, TESOL conventions, and ELTSummits. He offers candid, classroom-based insights, as demonstrated by his plenary keynote for the Defense Language Institute (DLI) in 2023. Titled “Chalkboards to Chatbots: Exploring Edtech Tools for English Teachers and Sharing Some Emerging Best Practices”, the address reviewed the profound changes in teaching English over the last 25 years. It also offered the audience of 200 experienced DLI English teachers some practical strategies for using generative AI while working with international military officers and pilots from American allies.
During the COVID crisis, Roth was a plenary speaker at the 2020 Virtual ELT Summit. Roth gave the opening presentation at the 2021 ELT Summit on hedging and boosting language in academic writing. Roth encouraged anxious English teachers to consider the positive possibilities of generative AI in a December 2023 DIESOL podcast. “Let’s not rush to worst case assumptions and apocalyptic conclusions,” said Roth. “We don’t know what happens next, and our choices do matter.”
Working with students to develop and deepen their academic writing and public speaking skills in English, Roth has taught numerous courses at the University of Southern California (USC) since 2003. His educational foundation – a B.A. in philosophy from Wabash College and an M.A. in Media Studies from The New School University – helps explain his approach, which integrates ideas, language, persuasion, and communication studies. He has also served as an educational consultant and led numerous teacher training workshops, sharing his practical expertise with educators.
Before focusing on English language education, his work as an education reporter, political journalist, and a Congressional aide, sharpened his awareness of how language can shape perceptions, experiences, and public policies. This real-world experience informs his teaching, making him an effective and popular teacher for international students, adult learners, and ambitious professionals who need English to be a precise tool for academic achievement and professional success. His career also includes directing the CES Adult Education Center (1996 to 1999), where he helped thousands of adult learners, primarily refugees from the former Soviet Union and the Islamic Republic of Iran, build their new lives and become American citizens.
Roth’s teaching career reaches back to 1992, with classroom experiences across high school, community college, adult education, and university classrooms. This large range – in levels, incomes, and interests – gives his work a practical, classroom-tested quality focusing on clear communication and explicit expectations. Another life lesson? Audience, context, and purpose always matter.
Today Roth continues to champion English teaching that is communicative, humane, and useful. His work emphasizes that fluency in English opens many doors and creates new possibilities. Authentic speaking skills mean creating better conversations, asking sharper questions, and moving more comfortably in a wider circle of social situations. So far, Roth has traveled to over 40 countries and his books have inspired English learners in over 60 countries.
