I believe the answer is:

teacher

I'm a little stuck... Click here to teach me more about this clue!

'schoolmaster' is the definition.
(I know that schoolmaster can be written as teacher)

'the race dispute' is the wordplay.
'dispute' is an anagram indicator (I've seen 'disputed' mean this).
'the'+'race'='therace'
'therace' is an anagram of 'TEACHER'.

'involved in' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for teacher that I've seen before include "Member of school staff" , "CARRY ON FILM" , "one of the staff" , "School educator" , "Schoolmaster" .)
