Here they are: 15 formats for structuring a class discussion to make it more engaging, more organized, more equitable, and more academically challenging. [...] Every time I saw it in a lesson plan, I would add a note: “What format will you use? What questions will you ask? How will you ensure that all students participate?” I was pretty sure that We will discuss actually meant the teacher would do most of the talking; He would throw out a couple of questions like “So what did you think about the video?” or “What was the theme of the story?” and a few students would respond, resulting in something that looked like a discussion, but was ultimately just a conversation between the teacher and a handful of extroverted students; a classic case of Fisheye Teaching. The problem wasn’t them; in most of the classrooms where they’d sat as students, that’s exactly what a class discussion looked like. They didn’t know any other “formats.” I have only ever been familiar with a few myself. But when teachers began contacting me recently asking for a more comprehensive list, I knew it was time to do some serious research.
