You will definitely have been given the info, but you may not know what to look for. At uni, many teachers will lecture/deliver some content, but then students need to do independent learning on their own to find out more.
For every assessment there should be a clear explanation or brief in the course guide, and you should have been given that even before day 1, week 1. So it shouldn't come as a suprise to you that there is coursework due now - perhaps it requires some research on your part? Maybe it's contained in the readings?
In short, not everything you need to discuss for coursework or an exam comes from exactly what you have done in class - most comes from additional prep you do outside of class hours, following the course guide.
