Research literacy is, put simply, the readiness to find, read and evaluate research, to carry insights from it into your practice, and to ask (and answer) your own questions about that practice in ways that are systematic and ethical. Over the years, quite a few posts on this blog have dealt with one or more of these aspects, and this page brings them together. I have written it mainly with language teachers in mind, both in service and in training, as well as the teacher educators who work with them.
I have grouped the posts according to these dimensions of research literacy, rather than by date (dates refer to the year when a post was created, although many of them have been updated since then). Each entry comes with a short note on when it might be useful. If you are looking for more technical advice on questionnaire design, statistics or multilingual research, you will find it on the companion page, Resources for Research Methods.

If you only have time for three posts, these are the ones I would suggest:
Empowering Language Teachers: The Research Literacy Framework
What is language teacher research literacy? In this post, we present an article that defines research literacy and talks about a framework that can designed to support teachers’ professional growth.
Making Research Work for Language Teachers
This post discusses the importance of teacher research in language education, arguing that teachers actively engage in research-like activities, even if they don’t label it as such.
The Knowledge Infrastructure Language Education Never Built
Language teachers generate potentially useful knowledge every day, but much of it never travels beyond the classroom. What might language education learn from other professions about transforming individual experience into shared professional knowledge?
1. Why research literacy matters
- Empowering Language Teachers: The Research Literacy Framework (2025). Useful when you want a working definition of research literacy and a framework for developing it.
- Thinking about the teaching-research gap (2023). Useful when you want to think about why research and classroom practice so often seem to talk past each other.
- Developing research literacy skills for language teachers: The ReaLiTea project (2023). Useful when you want to understand why research literacy matters now, and how one international project set out to address it.
- The Knowledge Infrastructure Language Education Never Built (2026). Useful when you wonder why so much of what teachers learn never travels beyond the classroom, and what other professions do differently.
- Research Engagement Among Language Teachers for Refugees and Migrants in Greece (2026). Useful when you want to see how teachers in one demanding setting actually engage with research.
2. Reading research critically
Being research literate starts with knowing what to trust.
- Writing a Literature Review: Three Tasks, Not One (2026). Useful when you are reading your way into a topic and want to organise what you find.
- Becoming Research Literate: Supporting Teacher Research in ELT (2018). Useful when you want a free, book-length introduction to research literacy in ELT.
- How to spot a predatory journal (and why to avoid them!) (2018) and What do predatory journals look like? (2015). Useful when you need to judge whether a journal, and what it publishes, can be trusted.
- Can You Take the Mean of Likert Scale Data? Ordinal vs Interval Explained (2013). Useful when you want to recognise a common statistical error in published research on language education.
3. Bringing research into practice
- Making Research Work for Language Teachers (2025). Useful when you suspect you already do research-like work in your teaching, and want to see it that way.
- Writing as Theorising for Language Education (2025). Useful when you want to use reflective writing to connect classroom experience with theory.
- Inclusion beyond translation: A conversation with Maria Cioé-Peña (2026). Useful when you want to see how research on inclusive, multilingual pedagogy meets classroom decisions, and where the gap remains.
The ReaLiTea project

Many of the more recent posts on this page grew out of Research Literacy for Language Teachers (ReaLiTea), an Erasmus+ project that brings together seven universities across the European Education Area, and in which I lead the University of Thessaly team.
The project treats research literacy as part of reflective practice for inclusive language teaching. Among other things, it is developing ways of describing and assessing research literacy, open educational resources for student teachers and practising teachers, plain-language summaries of published research, and an online community of practice where teachers can exchange ideas.
If you would like to know more about the project, or how you or your school might take part, the links below are a good place to start.
4. Researching your own practice
Getting started
- Doing Classroom-Based Research (2015). Useful when you want to start exploring your own practice systematically.
- Understanding the dynamics of a language classroom (2012). Useful when you need to map the context you are studying: physical, institutional, methodological and human.
- How not to do a research project (2014). Useful when you are planning research in a school and want to avoid problems that could compromise it.
- Doing research without a control group (2013). Useful when your design cannot include a control group and you want to know whether that matters.
Observing lessons
- A classroom observation framework (2020). Useful when you are about to observe a lesson and need to decide what to look for.
- Classroom Observation for language teachers: A how-to guide (2023). Useful when you want step-by-step guidance on planning, conducting and reflecting on an observation.
Research ethics
- On obtaining consent: can information manipulation be morally justified? (2012). Useful when you are writing participant information and want to think about how framing shapes consent.
- Breaching confidentiality in research (2014). Useful when you want to understand how far your duty to protect participants extends.
- Reporting data inaccurately: why, when and how to confidentialise data? (2013). Useful when you need to disguise details to protect participants.
- Do I need permission to evaluate language teaching textbooks? (2014). Useful when your project reproduces published teaching materials.
5. Joining the conversation
- Five benefits of attending conferences (2015). Useful when you are deciding whether a conference is worth your time.
- How to present a conference paper (2014). Useful when you are preparing to share classroom research with colleagues.
- Empowering language teachers through AI and research literacies workshop (2025). Useful when you want to see what a research-literacy workshop for teachers looks like in practice.

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 perspective to tease out connections between them. Some of his work 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 AI Lang (Artificial Intelligence in Language Education) expert team at the European Centre for Modern Languages of the Council of Europe, he is active in 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 to engage with, and contribute to, educational research. Alongside these, he contributes to LocalLing (Revitalisation of Linguistic Diversity and Cultural Heritage), a Horizon-funded initiative for the preservation of heritage and minority languages globally.
In addition to the above, Achilleas is the (co)editor-in-chief of the European Journal of Education and Language Review, and welcomes contributions that explore the dynamic intersections between language, education, and society.
