Educationalist provoking storm and noise (10)

I believe the answer is:

montessori

'educationalist' is the definition.
(Maria Montessori, 1870-1952)

'provoking storm and noise' is the wordplay.
'provoking' indicates anagramming the letters (letters provoked into a new form).
'and' says to put letters next to each other.
'storm' after 'noise' is 'noisestorm'.
'noisestorm' anagrammed gives 'MONTESSORI'.

(Another definition for montessori that I've seen is " education expert".)

I've seen this clue in The Times.
