Profile
Sean Mahoney taught at high school and university levels in Canada before coming to Japan in 1995 with an MA in English from the University of Victoria. He is Professor of English at Fukushima University, where he has enjoyed teaching for over 25 years. Along with two university textbooks, he has published articles and book chapters in several countries on foreign language acquisition, including error gravity, mutual intelligibility, team-teaching issues, speech rate, and Japan's English language education policy. He has recently completed a chapter in
Team Teachers in Japan: Beliefs, Identities, and Emotions
, which was published by Routledge in summer 2023, and is currently working on two textbooks.
User Research Outline
I have recently published on a 5-year, MEXT-sponsored inquiry into the teaching of English at Japan's primary schools, particularly the contributions from so-called non-native English speaking assistant teachers. I had conducted a nationwide survey of 277 members of this increasingly important group of educators, both Japanese and non-Japanese, as the parameters on language use and ownership issues continue to expand.
For my next research project, I'd like to reconsider a project from 2006-09, in which I focused on comparing the weight of different types of written errors in English (a research field called Error Gravity or 誤りの重み, 誤りの深刻度). This time, however, I would like to focus on the ranking of specific phoneme-related (or spoken) errors. Since mutual intelligibility is paramount in English Lingua Franca communication, it is necessary to determine which consonant and vowel distinctions have the greatest impact on comprehensibility and intelligibility. I have thus been studying the concept of Functional Load (機能負担量, 機能的負荷) and suprasegmental variance, and am training myself in how to use the PRAAT Spectrogram, which analyses acoustic sound waves. I would like to see whether the notion of Functional Load, if combined with key findings from Error Gravity studies, may contribute to improving English pronunciation teaching in Japan.
