1. dunce 傻瓜、差生
The followers of Scottish theologian and scholar Duns were considered enemies of learning by 16th-century humanists and reformers, who referred to them as 『dunces』. So if classroom or scholarly foolishness is the sticking point, then dunce is the right word for you.

2. ignoramus 無知者
『Ignoramus』was the endorsement given by a grand jury when they considered the prosecution’s evidence for an indictment not sufficient to warrant the case going forward.
