Professor Jeanine Treffers-Daller
Job Title:
Professor of Second Language Education
  • Director of the Centre for Literacy and Multilingualism
  • Convenor of the Second Language Acquisition Research Group


Second Language Teaching and Learning, Assessment and Measurement, English and Language: Study Skills and Research Methods (MA in Education)

Areas of Interest:

Areas of Expertise and Research Interests:

  • Bilingualism and Language Contact
  • Code-switching, borrowing, transfer and contact-induced change
  • Measuring bilingual language proficiency
  • Second Language Acquisition
  • The expression of movement in different languages
  • Vocabulary learning and teaching
  • Lexical richness
  • Native-like selection of lexical items in bilinguals and L2 learners

Examples of projects I have supervised at M-level:

  • Effects of reading tasks on incidental vocabulary acquisition
  • English vocabulary knowledge of asylum seekers: an analysis of picture stories
  • Using category fluency tests and semantic fluency tests to measure language ability in bilinguals
  • The effect of processing instruction on Chinese learners' acquisition of English counterfactual sentences
  • Forward transfer in L2 writing: The case of Chinese ESL learners in a secondary school

I welcome proposals in any area that is related to my research. I am particularly interested in M-level projects which aim to test how vocabulary or grammar points are best taught, either in English as a Foreign Language, or teaching of MFL in mainstream schools or teaching of community languages in complementary schools.

Research supervision:

Currently I am first supervisor for two PhD students:

  • Arjen de Korte: Should English grammar be taught explicitly to secondary school students in the Netherlands?
  • Zdislava Šiškova: lexical richness and cohesion in essays of Czech EFL learners

Completed PhD supervisions:

  • Majid Fatahipour: Lexical richness in essays of EFL students in Iran
  • Çiler Hatipoğlu: Cultural and gender differences in the use of apologies in English and Turkish in 2003 (within three years). Çiler now works as Associate Professor at Middle Eastern Technical University in Ankara.
  • Tomasz Korybski: Polish - English code-switching and other language contact phenomena in the speech of Polish migrants in the United Kingdom
  • Xu Ziyan: Motion event construal among Chinese and French EFL learners. She works as a teacher of English at Bejing Institute for Technology.
  • I have also been second supervisor of other PhD students who work on formulaic sequences in essays of Chinese EFL students, and on modality markers in the ambassadorial speeches of American and British ambassadors in Vietnam.

I welcome further applications from PhD students in areas related to my own research specialisms.

Current and recent research projects:

Most of my research focuses on Bilingualism and Language Contact, in particular on code-switching, borrowing and contact-induced language change.

More recently I have worked on conceptual transfer and the relationship between language and thought in bilinguals and L2 learners, in particular in relation to motion event construal (manner and path of motion). Recently I obtained funding from the European Science Foundation for an Exploratory Workshop on Thinking, Speaking and Gesturing in Two Languages (12-15 September 2012), together with Panos Athanasopoulos from the University of Newcastle. I have also studied vocabulary richness, native-like selection and syntactic complexity in Turkish-German bilinguals.

Work on vocabulary forms my second main area of interest. Currently I am working on the automated assessment of n-grams and lexical diversity in essays written for the Pearson Test of English Academic (funded by Pearson).

Together with other members of the M4 Applied Linguistics Network ( I organised an ESRC seminar series entitled Models and measures of vocabulary acquisition, knowledge and use: the interface between theory and applications from 2006-2007, which resulted in a range of publications: a jointly edited special issue of the Journal of French Language Studies (CUP), entitled Knowledge and use of the lexicon in French as a second language, of which I was the lead editor, as well as special issue of the International Journal of Bilingualism and a book with Palgrave.

Finally I co-ordinated the Learner Language Project at UWE Bristol which focuses on the development of oral proficiency of learners of English, French, German and Spanish. The data will be donated to the CHILDES database.
