Tá T.J. Ó Ceallaigh, B.Oid., M.Oid., Dioplóma Iarchéime (Ceannaireacht agus Bainistíocht Scoile), PhD, MA (Dearadh agus Forbairt na Ríomhfhoghlama) ina Léachtóir Sinsearach i Scoil an Oideachais, Coláiste na hOllscoile, Corcaigh. Is céimí é de Choláiste Mhuire gan Smál; Coláiste na hOllscoile, Corcaigh; Ollscoil na hÉireann, Gaillimh; agus Institiúid Teicneolaíochta Chorcaí, agus tá taithí an-fhairsing aige ar an gceannaireacht san ardoideachas agus ar an gceannaireacht scoile araon. Ina theannta sin, tá taithí den chéad scoth aige ar róil éagsúla ar an leibhéal náisiúnta san oideachas múinteoirí, san fhorbairt curaclaim, agus sa bheartas oideachais. Tá sé ina Leas-Cheann Scoile ar Scoil an Oideachais in UCC faoi láthair, agus sa ról sin cuireann sé le forbairt agus seachadadh na straitéise acadúla sa teagasc, sa taighde, agus i staidéir iarchéime.

Tá obair T.J. dírithe ar oideachas, forbairt, agus ceannaireacht múinteoirí, go háirithe i gcomhthéacsanna tumoideachais agus dátheangacha. Bíonn sé i mbun taighde freisin ar oideolaíochtaí digiteacha bunathraitheacha, comhtháthú na hintleachta saorga giniúnaí (IS giniúnach), agus cuir chuige nuálacha i leith an dearaidh foghlama. Is iar-phríomhoide é i scoil lán-Ghaeilge, agus bhí róil ceannaireachta sinsearaí éagsúla aige, mar shampla Stiúrthóir na Staidéar Iarchéime Múinte i gColáiste Mhuire gan Smál. Chaith T.J. tréimhse leis an tSeirbhís um Fhorbairt Ghairmiúil do Mhúinteoirí chomh maith agus é gníomhach ar an leibhéal náisiúnta i dtionscnaimh chun tacú leis an gcuraclam. Ar an leibhéal idirnáisiúnta, bíonn sé gníomhach ó thaobh beartais agus taighde de, agus is ball é de Thascfhórsa Idirnáisiúnta UNESCO maidir le Múinteoirí le haghaidh an Oideachais, 2030, agus Meitheal DELTA an Choimisiúin Eorpaigh ar an Oideachas Digiteach. Tá ról ceannaireachta aige i bpríomheagraíochtaí gairmiúla idirnáisiúnta freisin. Mar shampla, tá sé ina Chisteoir de Chumann na nOideoirí Múinteoirí san Eoraip, agus tá sé ina Chomh-Chathaoirleach ar an bPobal Taighde agus Forbartha um an Oideachas Múinteoirí agus um an Teicneolaíocht Dhigiteach ann. Tá sé ar an mBord Stiúrthóirí den Chumann um Chomhtháthú Ábhair agus Teanga san Ardoideachas (ICLHE) chomh maith.

Tá meas mór ar T.J. mar scoláire, agus tá réimse an-leathan páipéar agus ábhar eile foilsithe aige. Tá maoiniú os cionn €3.7 milliún bronnta ar a chuid taighde go dtí seo. Baineann an taighde sin le réimsí éagsúla, mar shampla oideolaíocht an tumoideachais, an cheannaireacht oideachais, foghlaim ghairmiúil múinteoirí, an t‑oideachas digiteach agus an t‑oideachas le cuidiú IS, agus an t‑ilteangachas. Tá an-tóir ar T.J. mar chomhoibrí, agus rinne sé cuid mhór tionscadail taighde ar an leibhéal náisiúnta agus Eorpach a stiúradh nó bhí sé ina chomhpháirtí iontu. Bhí sé ina stiúrthóir freisin ar réimse leathan tionscnamh taighde ar leibhéal dochtúireachta agus tacaíonn sé le mórchuid tionscnamh den sórt sin chomh maith. Bíonn sé díograiseach agus tiomanta i gcónaí ina chuid oibre ar fad do thabhairt le chéile an taighde, an bheartais agus an chleachtais, do chur chun cinn an oideachais lán-Ghaeilge agus ilteangaigh, agus do chur chun cinn na nuálaíochta san fhoghlaim dhigiteach agus san fhoghlaim le cuidiú IS.

Leadership and teacher development for immersion education

As a former immersion teacher and principal, T.J. has always been convinced that teaching language through content is the most effective approach to teaching second language, and there is ample research evidence to support that conviction. His primary research interest focuses on the role of the instructional leader and on the pedagogy required for the successful integration of language and content instruction, particularly in immersion contexts, where an indigenous language (e.g., Irish) is used as the vehicle for teaching academic subject matter. Particular topics of research interest include:

• Teacher education and development for immersion, bi- and multilingual contexts
• Form-focused instruction in immersion
• Context-appropriate crosslinguistic pedagogy
• Teacher language awareness in immersion
• Content and language integrated instruction.

Transformative digital pedagogies 

T.J. has a particular expertise in the integration of digital technologies within teaching and learning to allow pedagogy and technology to support each other in a blended learning design. He continues to explore and research highly innovative and complex digital technologies to develop novel pedagogical approaches in blended learning design, more recently by the integration of Common European Framework of Reference for Languages (CERFL) practices in hyflex postgraduate programmes in education. Particular topics of research interest include:

• HyFlex, digital and blended learning models
• Online teaching presence
• Learning design
• Digital assessment and feedback design
• Quality assurance in digital higher education.

T.J. demonstrates an internationally recognised, research-intensive teaching profile, underpinned by sustained leadership in the design, delivery, and strategic development of teaching and learning across undergraduate, postgraduate, and teacher professional learning contexts. His teaching spans large-scale undergraduate programmes, specialist postgraduate cohorts, doctoral supervision, and executive-level professional learning, evidencing both breadth of reach and depth of expertise. He has led and transformed curricula in teacher education, particularly in the domains of immersion education, language pedagogy, digital learning, and teacher professional development, embedding cutting-edge, evidence-informed and future-oriented pedagogies. His approach is characterised by the integration of HyFlex and multimodal learning architectures, research-led teaching, and high-impact assessment design that foregrounds learner agency, criticality, and professional identity formation. He has a strong track record of cultivating intellectually demanding and inclusive learning environments that support diverse student populations while maintaining excellence at scale. His teaching is further distinguished by its close alignment with his research and policy engagement, ensuring that programmes remain at the forefront of international developments in education and that graduates are equipped as intellectually agile, critically reflexive, research-engaged professionals capable of leading transformation across diverse educational settings.
