Tinker to adopt new practices

Harvard Graduate School of Education ProfessorKaren Brennan sees classrooms as magical spaces when we begin with curiosity, not just content.

“When I think about design process, from the initial moments of young people working on projects, all the way to the end where they've gone through the highs, the lows, the emotional vicissitudes of bringing their ideas into the world, the messy middle through to the end, there is a role for questions in every moment,” she says. “Start with questions, for me, is really about an attitude of leading with student interests.”

Drawing on a yearlong study of 25 teachers across elementary, middle, and high school classrooms, Brennan describes how powerful learning begins by asking genuine questions, or really questions teachers don’t already know the answers to. She is the co-author ofStarting with Questions: The Classroom as Design Studio, which explores what happens when educators take students’ ideas seriously.

Rather than treating questions as a closing ritual at the end of a lesson, Brennan argues for an orientation shift: start with what learners are thinking about, what they care about, and what feels hard or exciting to them. Grounded in traditions of progressive education, this approach does not reject content knowledge. Instead, it reframes the role of teachers as expert guides, offering domain expertise, metacognitive scaffolding, affirmation, and structure within a classroom culture that values intellectual humility.

Brennan comes to the classroom from a design studio background, a space that embraces tinkering and where self-directed learning happens in community. In studio-based environments, students pursue projects that matter to them while learning alongside peers and with the support of teachers. Self-direction, she explains, is not scriptless chaos but more structured, scaffolded, and deeply relational.

That mindset also shapes her optimism about artificial intelligence. Brennan argues that AI is not about offloading thinking, but about expanding what learners can imagine and build. “I feel like we don’t give learners enough credit,” she says. “When there’s all this handwringing around AI stealing assignments, maybe we were asking students to do things that weren’t that important to begin with. If AI can do it, maybe we need to be looking for new opportunities for interestingness for learners.

In this episode, Brennan pushes beyond traditional classroom approaches toward a powerful idea: how classrooms become transformative when we make space for students’ questions and trust their capacity to pursue them.
