Self-introduction
Jon conducts research on the assessment of vocabulary knowledge, second language (L2) productive vocabulary development, productive vocabulary knowledge and fluency, second language acquisition, word association studies, lexical processing, and second language assessment. He has analysed various methods for measuring productive vocabulary, focusing on isolating the specific aspect of productive vocabulary knowledge. His research has appeared in journals such as Bilingualism Language and Cognition, Tesol Quarterly, Language Testing, System, The International Journal of Bilingual Education and Bilingualism, and Language Teaching and Research. He is a co-author of First Language Influences on Multilingual Lexicons (Routledge, 2020)), Vocabulary and the Four skills (Routledge, 2021), and EAL Research for the Classroom, Practical and Pedagogical Implications (Routledge, 2023), ..................................................................................................

  2. 2022, Vocabulary and the Four Skills: Pedagogy, Practice, and Implications for Teaching Vocabulary, This edited volume provides a single coherent overview of vocabulary teaching and learning in relation to each of the four skills (reading, writing, listening, speaking). Each of the four sections presents a skill area with two chapters presented by two leading experts in the field, relating recent advances in the field to the extent that each skill area relates differently to vocabulary and how this informs pedagogy and policy. The book opens with a summary of recent advances in the field of vocabulary, and closes by drawing conclusions from the skill areas covered. The chapters respond to emerging vocabulary research trends that indicate that lexical acquisition needs to be treated differently according to the skill area.

  3. 2021, L1 backgrounds and multilingual lexicons, This collection brings together recent research on the influences between first and additional languages with a focus on the development of multilingual lexicons. Featuring work from an international group of scholars, the volume examines the complex dynamics underpinning vocabulary in second and third languages and the role first languages play within this process. The book is organized around three different facets of research in this area – lexical recognition, processing, and knowledge; the effects of first languages on second language reading and writing, collocations, and translation skills; and, vocabulary testing – drawing on examples from a variety of languages, including European languages, Arabic, and Japanese. Setting the stage for further research on the interplay between first languages and multilingual lexicons, this volume is key reading for students and researchers in applied linguistics, language learning and teaching, bilingualism, second language acquisition, and translation studies., This collection brings together recent research on the influences between first and additional languages with a focus on the development of multilingual lexicons.
