I'm not good in doing presentations and I'm not sure if it is a common style or technique that to engage your audience, you need to ask a show of hands if they know about something..

I attended a "meeting/workshop" and the presenter just kept on asking who among us knows blah, have read blah, have seen blah, who doesn't know blah blah blah.

Why ask us to raise our hands? Are u conducting a survey? For those who raised their hands did u feel a sense of belongingness? For that one guy who raised his hand he was bullied.

I don't understand why ask ppl to raise their hands? For what?

If u want to share info then just deliver the message. Full stop. Don't make it embarrassing for the rest of us.
