It’s wrong, note, when one sees nothing in basic education (5)
I believe the answer is:
error
'it's wrong' is the definition.
(thesaurus)
'note when one sees nothing in basic education' is the wordplay.
'note' becomes 'e' (musical note).
'when one sees nothing' becomes 'o' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'basic education' becomes 'rrr' (the three R's - reading, writing and arithmetic).
'o' going inside 'rrr' is 'rror'.
'e'+'rror'='ERROR'
Can you help me to learn more?
(Other definitions for error that I've seen before include "Faulty judgment" , "Miscalculation" , "Bloomer, blunder" , "heresy" , "Solecism" .)
