Article for number one educationalist to review critically (6)
I believe the answer is:
bedpan
'review critically' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'article for number one educationalist' is the wordplay.
I cannot really understand how this works, but
'article' could be 'an' (indefinite article) and 'an' is found within the answer.
'number' could be 'e' (e is a kind of number) and 'e' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Another definition for bedpan that I've seen is " Hospital receptacle".)
