Ideas came free in places of learning (9)

I believe the answer is:

academies

'places of learning' is the definition.

'ideas came free' is the wordplay.
'free' is an anagram indicator.
'ideas'+'came'='ideascame'
'ideascame' is an anagram of 'ACADEMIES'.

'in' acts as a link.

(Other definitions for academies that I've seen before include "specialised schools" , "Places of study" .)

I've seen this clue in The Telegraph.
