Build Better Lessons with a 3-Part Context Brief

Renata Salas

One teaching method you can use tomorrow morning. It-it-it's called the Context Brief, and it comes from Wendy Turner in Edutopia, back in June of 2026, in her article "Turning Lesson Ideas Into Usable Resources With AI." And, okay, here's the thing. Most of us, when we sit down with ChatGPT or whatever, we do this thing where we just type in, um, "Write me a lesson on possessive nouns." Right? It's the default. But it is completely the wrong starting point.

Colin Whitfield

Right, because you're-you're essentially treating the AI like an entry-level supply teacher who has just walked through the door five minutes before the bell rings. It has zero idea who is actually sitting in those desks.

Renata Salas

Yes! Exactly! If a human colleague came up to me and said, "Hey, Renata, I need a lesson on possessive nouns," my first three questions aren't going to be about possessive nouns. They're going to be: Who are your students? What have they already done this week? And, like, what does your room actually need right now? And yet, we expect the machine to just, what, guess all of that?

Colin Whitfield

Well, it's quite interesting because if you look at the research on cognitive load and instruction--Rosenshine, for instance. One of his key principles is that expert teachers don't just teach content in a vacuum. They have these incredibly rich, almost instinctive mental models of their specific classroom. They know the sequence. They know that, ah, last Tuesday Bobby struggled with singular versus plural, so we can't just jump straight into possessive apostrophes. The AI, bless it, has none of that context unless you literally hand it to them on a silver platter.

Renata Salas

Exactly. So, if you want a usable plan, don't start with the topic. Start with the classroom. Because when we don't, we get these incredibly generic, beautiful-looking lesson plans that-that look polished on paper, but they completely fail on the one thing that actually matters in third period--fit. They miss on the reading level, they miss on the timing, the pacing, and honestly, they just don't sound like us.

Colin Whitfield

So, how do we actually fix this? What is Turner's actual workflow for this Sunday night or prep-period planning session?

Renata Salas

Okay, so it's a three-part Context Brief, and you do it in one single chat thread. You don't scatter it. First, you feed it your student context. And I mean real, specific details. Not just "second grade." You tell it: "I have twenty-two second graders. Six of them are reading below grade level. We have two English language learners who need visual scaffolds, and, um, we just finished singular versus plural nouns yesterday." That is your step one.

Colin Whitfield

Right, so you're establishing the baseline first. What's the second input?

Renata Salas

Second is a sample. You upload or paste in a lesson you've already taught that actually went well. Something where you're like, "This is my style. This is how I structure my warm-ups, this is how I talk to my kids." You're giving it your voice.

Colin Whitfield

Ah, that's brilliant. So you're training it on your own pedagogical DNA, rather than letting it generate some dry, standard textbook template. And then the third part?

Renata Salas

The third part is the destination. What are you actually trying to build? For Turner, she used this exact setup for her second-grade apostrophe unit. Instead of getting a generic, boring worksheet, she told the AI she wanted a four-day slide deck with fifteen-to-twenty-minute daily lessons, and a super low-stakes five-question quiz at the end to see who got it. And because she gave it those three inputs first, the AI actually built exactly that. It matched her exact pacing.

Colin Whitfield

I love the metaphor Turner uses for this. She says, "I now often use AI to build that bridge." It really is a bridge, isn't it? The brief is the bridge between the chaotic, brilliant idea you have in your head and the actual, structured resource your students need tomorrow morning.

Renata Salas

Yes! But-but we have to be real here. Turner is super explicit about this. The AI gets you to about eighty percent. You still have to do that last twenty percent of the heavy lifting. That's the quality control, the final revisions, the tweaking of the language. It-it requires patience and a little bit of finesse. It's not a magic "easy" button, and if you expect it to be, you're going to be disappointed.

Colin Whitfield

Quite right. It's a partner, not a replacement. So, if a teacher is sitting at their laptop tomorrow, what does this prompt actually look like when they paste it into ChatGPT, or Claude, or MagicSchool?

Renata Salas

Okay, so write this down or picture this in your head. You paste this: "I am planning a lesson on [insert your topic, like possessive nouns] for my class. Here is our context: . Here is a sample of a lesson my students loved: . Please design a [insert format, like a 4-day slide deck] with a daily learning target of that fits into a [insert duration, like 20 minutes] time block. And--this is key--please flag any prerequisite skills my students might struggle with based on this plan."

Colin Whitfield

That's the golden ticket right there. It forces the machine to think like a teacher.

Renata Salas

It really does. Alright, that's our quick take for today. Go try it out on your prep period tomorrow, and we'll talk soon.
