Hi everybody, 
My name is Jade. My major is education. I am doing a portfolio about the impact of local and international events on curriculum. I got some question. Hope you can help me to answer it: 
- What is the role of artifact? Is it simply an evidence of the topic, events which are collected in portfolio or I need to count what other authors wrote in that artifact on my analysis? 
- What does "Discussion of editorial differences between the sources" mean? What do I need to do to meet that requirement? 
Thank you so much.
