This document provides feedback on essays and guidance for improvement. Key points include: 1) Students must thoroughly review comments and grading rubrics to understand where marks were lost. 2) Essays should be several pages long and include a variety of recent, global case studies from different sources to earn high marks. 3) Introductions need to clearly establish the purpose and include relevant context. Conclusions should thoroughly summarize case studies. 4) Analysis must discuss both positive and negative impacts on people and consider a range of perspectives, rather than simplistic statements.
