I shall not be updating this blog regularly over the next few weeks, on account of pressing commitments that now require my undivided attention.
I hope to be able to post in response to topical stories, or share news that I find interesting, but I will not be able to do so in a regular, sustained way as I endeavoured to do over the past few months.
Looking forward to engaging with you all in a few weeks.

A new issue of the European Journal of Language Education & Language (2/1)
Why launch another journal in language education? In this editorial reflection, I explain the vision behind the European Journal of Education and Language Review and introduce Issue 2(1).
AI-Assisted Teacher Reflection: Thinking Before, During, and After the Lesson
Teaching has always required reflective practice. This post explores how artificial intelligence can support three types of teacher reflection (before, during, and after the lesson) drawing on Farrell’s framework and the AI Lang guidelines.
Being and Becoming a Plurilingual Academic: A new book in the making
Our upcoming book, Being and Becoming a Plurilingual Academic explores what it means to teach, research, publish, and build an academic identity in a higher education system where English has become the default language.

About me
Achilleas Kostoulas is an applied linguist and language teacher educator at the Department of Primary Education, University of Thessaly, Greece. He holds a PhD and an MA in Teaching English to Speakers of Other Languages from the University of Manchester, UK and a BA in English Studies from the National and Kapodistrian University of Athens, Greece.
His research explores a wide range of issues connected with language (teacher) education, including language contact and plurilingualism, linguistic identities and ideologies, language policy and didactics, often using a Complex Dynamic Systems Theory to tease out connections between them. Some of his work in the field includes the research monograph The Intentional Dynamics of TESOL (2021, De Gruyter; with Juup Stelma) and the edited volume Doctoral Study and Getting Published (2025, Emerald; with Richard Fay), as well as numerous other publications.
Achilleas currently contributes to several projects that bring together his long-standing interests in language education, teacher development, and the social dimensions of language learning. As the coordinator of the expert team of AI Lang (Artificial Intelligence in Language Education), an initiative of the European Centre for Modern Languages of the Council of Europe, he works on developing principles and resources to help educators make informed, pedagogically grounded use of AI in their teaching. He also leads the University of Thessaly team of ReaLiTea (Research Literacy of Teachers), a project that supports language teachers in developing the capacity to engage with, and contribute to, educational research. Alongside these, he contributes to LocalLing, a Horizon-funded initiative to preserve and strengthen heritage and minority languages globally.
In addition to the above, Achilleas is the (co)editor-in-chief of the newly established European Journal of Education and Language Review, and welcomes contributions that explore the dynamic intersections between language, education, and society.
