Model recalled art teacher's education (5,3)
I believe the answer is:
train set
'model' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'recalled art teacher's education' is the wordplay.
'recalled' says the letters should be written in reverse (to recall can mean to bring something back).
'teacher's education' becomes 'inset' (I can't explain this - if you can you should believe this answer much more).
'art' back-to-front is 'tra'.
'tra'+'inset'='TRAIN-SET'
Can you help me to learn more?
(Other definitions for train set that I've seen before include "Nitrates (anag) - Hornby product?" , "Model tracking" , "little loco with this?" , "A child might play with this" , "Toy for dads?" .)
