Eccentrics pursuing Zoom as a learning aid (5,5)

'learning aid' is the definition.
Although both the answer and 'aid' are nouns, they are not in the same form of the noun. However, I know that 'learning' relates to this answer.

'eccentrics pursuing zoom as a' is the wordplay.
I cannot really see how this works, but
'as' is present in the answer.
'a' is within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
