My Take
I like that this tool emphasizes collaboration; I think this is a great intrinsic motivator. The high reward possibility also achieves this. Any way to incorporate creative writing into a high school English classroom is a positive option for me that I will almost always be willing to incorporate.
How I Use It
I would use this as an in-person, full-class activity. I would do it around once a month in order to build the class’s hype around it, and as a break from the traditional expository writing we’re required to teach.
