Forget about the “.” Read “Period. Full Stop. Point. Whatever It’s Called, It’s Going Out of Style” at http://www.nytimes.com/2016/06/10/world/europe/period-full-stop-point-whatever-its-called-millennials-arent-using-it.html?mwrsm=Facebook&_r=0
From one of my graduate students:
ReadWriteThink had a great lesson on semicolon use. While not specific to the way they are used in lists, I think this would be an excellent way to explore semicolons with students in authentic text. The lesson suggests using powerful writing by Dr. Martin Luther King and first going through and just circling the semicolons, then going back and exploring how and why he used them and how they made his message more powerful in different places. I liked that this lesson idea focuses on semicolons in context and is an exploration activity. Definitely for secondary students.
