Not allowed? I think the verse refers to teaching on spiritual matters, in the context of proper position in the Church. My father just took an on-line class taught by a female for the physically disabled to make basic meals. Given the topic, it seemed perfectly natural for a woman to teach.
Yeah I think the verse refers to teaching in a way like the Church teaches, i.e with authority. Letting a woman show you how to do something, or tell you about a topic, isn't teaching in this context. It's women having authority over adult men that's the issue, which lines up with how secondary schools were traditionally split by gender and no young man would've had female teachers anymore after that.
