Not related to education or not intended to teach.
The movie was entertaining but completely noneducational.
Noneducational → It is formed from "non-" (meaning not) and "educational" (from Latin "educare", meaning to bring up or rear). The word "noneducational" means not related to or not providing education.
Think of 'not' ('non-') related to 'bringing up' or 'rearing' ('educare') — that's why noneducational means something that does not provide education.
