Hi,
I read this blog from Edutopia that I wanted to share with the community. It highlighted a lesson for middle schoolers, but I believe would be perfect for adult learners. In the lesson, students were given the opportunity to analyze the text from two or more authors. The iPad was used as a reference tool for the class. The blog was titled Common Core in Action: Examining 2 Texts in the Social Studies Classroom. I hope that you get some ideas from it.
