The Welsh teenager, who missed his A-level exams to take part in the reality TV show, told producers he wanted to become a teacher after helping fellow housemates learn Welsh.
Glyn, 18, who was head boy at Ysgol Duffryn Conway in north Wales, said:
"It's shown me that I want a career in teaching once I get out."
UCAC, the Welsh teachers' union, said it would be proud to have Glyn in the profession.
Eryl Owain, its north Wales field officer, was Glyn's form tutor and AS-level history teacher.
He said: "We need more young people, especially men, in the profession in Wales and Glyn would fit the bill very well."
Mr Owain said that despite the teenager's antics, Glyn was still a good role model.
"Getting drunk and being sick and a bit silly is normal behaviour for most young people," he said. "Unfortunately for Glyn, it's all been shown on live TV.
"He has so many positive aspects though. He is very popular with young people in Wales and has strengthened their affinity to the language. It doesn't surprise me that he wants to teach."
Glyn, one of the final contestants in the show, was due to sit A-levels in art, English and Welsh this summer, but missed them because of the Channel 4 programme. Mr Owain said he could still go to university in the autumn with UCAS points accrued from AS-levels, coursework and modular exams.
A spokesman from the Department for Education and Skills acknowledged Big Brother reached a wide audience of young people who could be inspired to follow Glyn's example.
He said: "Teaching is a rewarding profession and a very attractive option for young people."
