Carried out work in charge of teaching (8)
I believe the answer is:
didactic
'of teaching' is the definition.
(I've seen this before)
'carried out work in charge' is the wordplay.
'carried out' becomes 'did' (I've seen this before).
'work' becomes 'act' ('act' can be a synonym of 'work').
'in charge' becomes 'ic'.
'did'+'act'+'ic'='DIDACTIC'
(Other definitions for didactic that I've seen before include "Intended to teach or instruct" , "Informative" , "Teaching morally" , "Imparting a lesson" , "Edifying" .)
