The name and the practice are Christopher Emdin's. *Cogen* is short for cogenerative dialogue, and he wrote them up in *For White Folks Who Teach in the Hood... and the Rest of Y'all Too*: > Cogens are simple conversations between the teacher and their students with a goal of co-creating/generating plans of action for improving the classroom. > > — Christopher Emdin, *For White Folks Who Teach in the Hood*, p. 65 They fit a Cavendish Space closely. In a cogen, people take part as "experts on their own unique relationship to the social field that is the classroom" (p. 66). The people in a room are the experts on it. And the conversation ends in a plan for the room. This page is how to hold one with the deck. Why the two fit, and where they part, is on stimpunks.org: [Cogens and Cavendish Space: A Crosswalk](https://stimpunks.org/space/cogens/). ## What this is, and what it refuses to do - **A cogen is about the room.** Every change it plans is a change to the room, the kit, the permissions, or the pace. - **It is not a behavior meeting.** No line of the plan takes a person or a group as its subject. - **Nobody has to speak.** A card turned up is a turn. So is a typed line, a message on an AAC device, or a pass. - **Nothing is counted.** A need named once is a need. Access is not a vote. - **Sharing stays with the person.** Cards go down face-down. The turn is the consent. ## Three rules, with the mic made wider Emdin keeps a cogen to three rules. Here they are in his words: > The rules should be given to students in the most succinct version possible: > > - No voice is privileged over another, or, “Everybody eats, everybody speaks.” > - One person speaks at a time; or “one mic.” > - The cogen results in a plan of action for improving the classroom. > > — Christopher Emdin, *For White Folks Who Teach in the Hood*, p. 73 We keep all three, and widen the first two. 1. **Everybody eats.** No voice counts for more than another — and a spoken voice does not count for more than a laid card. Everybody gets the mic. Nobody has to take it. 2. **One mic.** One turn at a time. A turn can be words, a card turned up, a typed line, or a pass. The quiet while someone finds their words is part of their turn. 3. **It ends in a plan.** A short list of changes to the room. Not to the people in it. ## Before - **Say what it is for, out loud, before anyone lays a card.** "We're working out what to change about this room." If spreads will go through an AI later, say that too. [Group access needs](group-needs.html) says why. - **Post the question first.** *tell me first* is the card that most often helps. Try: *What makes this room hard to be in? What would help?* - **Keep it small.** A cogen is a campfire — a few people, not the whole class. Change who comes, so it is never the same few. - **Pick the place.** A campfire, with a cave and a way out close by. [Zone a room](rooms.html) works out whether the room can hold them. ## During - **Open with the deck, not with talk.** Everyone lays a spread face-down: a place, a weather, a couple of what-helps. Turn up what you choose to share. - **Go round once.** One mic. Each turn is a card turned up, a few words, or a pass. *you don't have to talk* is in the deck for this. - **Watching is taking part.** Someone can sit out a round and come in on the next. *watch first* and *not yet* are lily pads, not refusals. - **Leaving is not leaving the cogen.** *let me come and go*, *i need a minute*, *coming back*. The circle holds a place. - **Mirror it back. Reach for the room, not the person.** The same three moves as the [facilitator sheet](facilitator.html). - **Take the turns that come late.** Leave the question open for written answers until the end of the day. ## The plan - **The room is the subject of every line.** Not "students will stop calling out." Instead: "this room needs a written way to join the discussion." If a line has a person or a group as its subject, rewrite it or cut it. - **Use the room's own words.** The seventeen room conditions in [Group access needs](group-needs.html) — quiet, a way out, come and go, written down, another way to take part — go straight into [Zone a room](rooms.html). - **Do not vote. Do not tally.** If two changes compete for one afternoon, ask the people who will be in the room. That is what the cogen is for. - **Start with the permissions.** *sit my way*, *let me stim*, *let me come and go*. They cost nothing. ## After - **Carry the plan back.** The people from the circle carry the room's changes back to everyone else. They do not carry rules. - **Keep it in the library.** Post the plan where the room can see it — the library is where we keep what we've figured out. - **Open the next cogen with what changed.** And with what didn't. ## When a cogen stops working Emdin puts the choice plainly: "It essentially boils down to whether one chooses to do damage to the system or to the student" (p. 206). A cogen chooses the system. - **If a cogen keeps producing rules for people, it has stopped being a cogen.** Go back to the room. If it's not working, it's not the person. - **If the same voices fill every round, widen the mic.** More cards. More time to write. A smaller circle. ## Where this goes next - [Lay a spread](deck.html) before the cogen, or during it. - [Group access needs](group-needs.html) turns a pile of spreads into one brief for the room. - [Zone a room](rooms.html) sets the brief beside what the room already has. - [The facilitator sheet](facilitator.html) covers the deck's other ways to play. - [Cogens and Cavendish Space: A Crosswalk](https://stimpunks.org/space/cogens/) — the argument at length, on stimpunks.org. ## License This page is dedicated to the public domain under [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/), **except the quotations.** Quoted material belongs to whoever wrote it.
