"[Beverly] Cleary frowned on the moralizing, didactic themes that dominated children's literature in the first half of the 20th century. She set out not to impart wisdom but instead to portray children at play, and to capture their dialogue and the ways they sometimes venture into an adult world beyond their full comprehension."

Did You Know?
Didaktikós is a Greek word that means "apt at teaching."
It comes from didáskein, meaning "to teach." Something didactic does just that: it teaches or instructs.
Didactic conveyed that neutral meaning when it was first borrowed in the 17th century, and still does; a didactic piece of writing is one that is meant to be instructive as well as artistic.
Parables are generally didactic because they aim to teach a moral lesson.
Didactic now sometimes has negative connotations, too, however.
Something described as "didactic" is often overburdened with instruction to the point of being dull.
Or it might be pompously instructive or moralistic.
