In my Japanese book it gives the following examples:

Nihongo o hanashite mo iidesuka? Renshuu o shitai desu. = Do you mind if we speak Japanese, I would like to practice it.

ohanashi suru =  have a talk

Ohanashi dekite yokatta desu. = It was nice talking with you.

Motto oshiete kudasai! = tell me more

Anata no kazoku ni tsuite oshiete kudasai. = Tell me about your family

What's the difference between ohanashi and oshiete? They both seem to relate to talking/speaking, but I can't tell the difference.
