Your report is the culmination of a semester's worth of careful research, reading, note-taking, and consultation with your faculty mentor.
That said, some work in the field will be necessary before you deliver your report. Please observe the following guidelines to maximize your chances for success.
PREPARATION. Visit your site(s) in Rome as soon as you are able and walk around the space(s). Identify the details you hope to present and think about the logistics of presenting them. Where will you stand with respect to the site and your peers? How will you ensure that they see what you want them to see?
Some physical movement, whether on your part and/or on the group's part, is inevitable — and probably desirable — during your report. If your site covers a lot of ground in the literal sense, you should plan out the movements from point to point. Do note that such migrations, however instructive they prove to be, will not count toward your talking time of 15–20 minutes.
PRACTICE. Along with your logistical preparation, you should rehearse your report(s) at the site(s) out loud, as many times as you can. Rehearsal will re-familiarize you with your own narrative and make your talking points easier to negotiate. In addition, on-site rehearsal will help you tailor your talking points to the space.
Remember that an engaging presentation has a consistent and lively delivery. Consistency means that you have a sense of where your presentation is going and that you are delivering the material with confidence throughout. Liveliness comes from speaking with expression, making eye contact, asking questions, but not reading your talking points verbatim.
