Speaker: Agnieszka Leńko-Szymańska, Assistant Professor, Institute of Applied Linguistics, University of Warsaw.

Agnieszka's research interests are primarily in second language acquisition and corpus linguistics, especially in the issues related to lexis and phraseology in these fields. She authored a number of papers on the acquisition of second language vocabulary and formulaic language and on explorations of learner corpora. Her recent book Assessing and Defining Lexical Proficiency was published by Routledge in 2020. She teaches courses on applied linguistics, foreign language teaching methodology and second language acquisition as well as the applications of corpora in language instruction and learning.  

Title: Corpora in L2 vocabulary assessment

Abstract: This presentation will demonstrate how native and learner corpora can assist researchers, exam administrators and teachers in the development and use of valid, reliable and practical methods and tools for the measurement and evaluation of L2 lexis. Two approaches to vocabulary assessment will be discussed: discrete-point tests and performance-based assessment. First, these approaches will be briefly reviewed in the context of a model of lexical knowledge and proficiency, with the focus on the type of information captured by each approach. Next, the application of corpora for the selection of appropriate lexis for discrete-point assessment will be presented together with a selection of available lexical inventories (e.g. English Vocabulary Profile or Academic Word List) and tests (e.g. Vocabulary Levels Tests). In addition, a range of simple and more advanced text- and corpus-based vocabulary measures such as Type/Token Ratio or Lexical Frequency Profile will be discussed along with the tools that implement them (e.g. Text Profiler or Test Inspector). Finally, the talk will present the results of my own study in which lexical ability of advanced L2 learners and native speakers was evaluated using the two methods. Special attention will given to the comparisons of automatic lexical measures with human raters’ scores. It will be argued that different approaches to vocabulary assessment should not be treated as alternative but complementary ways of measuring lexical ability, each contributing its unique information to the comprehensive picture.

About International Perspectives on Corpus Technology for Language Learning - Seminar Series

Given the challenges to language education posed by COVID-19, increasing collaborative development in online pedagogies and resources ensures continuity of language education throughout the pandemic, while preparing students to succeed in an uncertain post-COVID-19 world. This seminar series is a global initiative spanning multiple time zones, with participants from Brazil, the UK, the USA, France, Poland and Australia, discussing the latest applications of language corpora for (language) learning. Topics include the use of corpora for language education, corpus pragmatics, text analytics for classroom use, data-driven learning, and much more, with a range of famous international speakers.
