Last week there was no episode; this week we begin the final module in the course, 'Communicating'.  There are lots of different contexts in which we share archaeological data, and lots of different ways to achieve that. Lots of different 'publics', too! In this week's materials, we're looking at the ways archaeologists inform each other about their work, share their data, and the 'open science' movement, which aims for both reproducibility and replicability. We're joined by Dr. Ethan Watrall, of Michigan State University, who, along with his colleague Lynne Goldstein, has pioneered new ways for archaeologists to communicate with each other and the broader public.
