R.A.F.T. is a really unique idea to get students to think about things from many different perspectives. You can use R.A.F.T. activities for any subject area. How it works is you assign your students to write something (Format) such as a letter, a speech, a map, an interview, etc. and they write it from a specific point of view. The topic is also specified by the teacher as well as who the writing is directed to. You can differentiate it for interest, readiness, and learning profiles. For interest, you can change the type of format to be something the student would be more interested in. If you have a student who is more argumentative, you can gear the format, role, and audience to fit their personality. As well as if you have a student who is more passive and compromising, you can gear R.A.F.T. toward them. To vary it for readiness, you can assign different formats and have different requirements for your students who need their assignment lessened.
I love the idea of them being usable for each subject area. You can have them write a letter about being a semicolon to the students about how to use it correctly. For math, students could write a speech about being an equal sign to an inequality sign about how equal signs are better. The options are endless! I would love to use this to assess student understanding of different subjects. I think that this will be helpful to get students to think deeper and in different ways.
