Tá an Dr T.J. Ó Ceallaigh mar Léachtóir Sinsearach/Ollamh Comhlach i Scoil an Oideachais, Coláiste na hOllscoile Corcaigh. An phríomhspéis taighde atá aige is ea díriú ar an oideolaíocht atá ag teastáil chun teagasc na teanga agus an ábhair agus an measúnú a chomhtháthú go rathúil, go háirithe i gcomhthéacsanna tumoideachais agus dátheangacha. I measc na bhfoilseachán is déanaí leis, cuimsítear ailt in International Journal of Bilingualism and Bilingual Education, Journal of Immersion and Content-Based Language Education, agus Educational Management, Administration and Leadership, agus bhí sé ar dhuine de na heagarthóirí freisin ar imleabhar maidir leis an bhforbairt múinteoirí le haghaidh an tumoideachais agus an teagaisc ábharbhunaithe (Benjamins, 2020). Glacann T.J. páirt ghníomhach i bpobail tumoideachais in Éirínn agus thar lear, bíonn sé ina chomhairleoir ar chláir thumoideachais, is minic é a bheith ina chainteoir ag comhdhálacha agus tá sé mar bhall freisin de roinnt comhfhiontair thaighde ar bhonn náisiúnta agus idirnáisiúnta. Ceapadh T.J. le déanaí ar Mheitheal an Choimisiúin Eorpaigh ar an Oideachas Digiteach: Foghlaim, Teagasc agus Measúnú (DELTA). I rith a théarma oifige cúig bliana, cabhróidh sé leis an gCoimisiún chun tacú le tíortha chun athchóirithe beartas a chur chun feidhme i gcomhréir leis an bPlean Gníomhaíochta don Oideachas Digiteach, 2021-2027. Díreoidh sé go háirithe ar oideachas digiteach ardchaighdeáin agus uilechuimsitheach a chothú san Eoraip, agus cuirfidh sé san áireamh freisin an claochlú digiteach agus impleachtaí ghéarchéim COVID‑19 agus na ceachtanna a foghlaimíodh ón ngéarchéim. Tá T.J. ina bhall den Chomhairle Riaracháin Thofa le Cumann Oideoirí Múinteoirí san Eoraip (ATEE) agus tá sé ina chomhchathaoirleach ar an bPobal Taighde agus Forbartha maidir le hOideachas Múinteoirí agus an Teicneolaíocht Dhigiteach, fóram dinimiciúil idirdhisciplíneach atá ann a bhfuil mar aidhm leis an léann criticiúil agus comhfhiontair thaighde a chothú chun an dioscúrsa poiblí agus an cleachtas i réimse an oideachais dhigitigh a mhúnlú. Ina theannta sin, tá sé mar Stiúrthóir Boird de Chomhtháthú Teanga agus Ábhair san Ardoideachas (ICLHE), cumann idirnáisiúnta scoláirí a bhfuil spéis acu i réimse ildisciplíneach an chomhtháthaithe ábhair agus teanga san ardoideachas agus a bhíonn ag cur leis an réimse sin ar bhealach gníomhach.

Leadership and teacher development for immersion education

As a former immersion teacher and principal, Dr Ó Ceallaigh 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

Dr Ó Ceallaigh 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 presenceLearning design
• Digital assessment and feedback design
• Quality assurance in digital higher education.
