• Why the Reading and Math Wars Keep Coming Back | Jon Star
    Nov 5 2026
    Education has seen it all before. A promising approach to teaching catches on, and then it becomes the center of a heated debate. That's happening with the science of reading, and increasingly, the science of math.But Harvard Professor Jon Star says these debates get at a bigger question in education: What counts as good research, and how should it guide decisions about teaching and learning?“Anyone with a megaphone or a social media platform or a lot of money can advocate for a particular way to teach. And they can claim that their way of teaching is supported by research evidence…,” Star says. “The debate is less about whether one method of teaching is better than another method of teaching. But it's really a debate about the type of research that supports each of those methods.”And it's something that education hasn't been able to get away from throughout its history.If you look back far enough, Star says, you can see some of the same debates we're having now about math as long ago as the 1800s, including debates over discovery-based learning and explicit instruction.In math education, what may appear to be one central argument is actually a collection of overlapping disagreements. This is partly why Star thinks it's valuable for educators to understand the history of education and the debates that go along with it.It's also the focus of his course, “Controversy in the Classroom: Debates on the Learning and Teaching of Math, Reading, and Science,” currently offered for both HGSE and Harvard College students.“I don't want to use the oft-repeated 'those who don't know the past are doomed to repeat it' kind of idea, but it does seem like there's a bit of that,” he says. “We need to know the ways this played out in the past in order to better understand and participate in the debate in the present.”Ultimately, Star says we need to focus on what's best for students, even though there's no single instructional approach that meets every student's needs.Research can offer important guidance about what approaches work better under particular conditions. But the challenge is balancing the evidence with an individual student's needs and the realities of classroom teaching.In this episode, Star shifts the focus away from simply defending one side of an education debate. Instead, he considers how educators, researchers, and policymakers can remain open to different approaches, ask better questions about the evidence, and work together to understand what helps children learn.In this episodeWhy the science of reading and science of math have become central to education debates.What people really mean when they talk about the science of education.Why disagreements over teaching methods are often disagreements about what counts as credible research.The history of the reading wars and math wars.Explicit instruction versus discovery-based learning in mathematics.What historical math textbooks and research studies reveal about how students learn.Why there is no one-size-fits-all approach to teaching.How educators balance research evidence with classroom experience.How education research influences media coverage, classrooms, and education policy.How educators and researchers can move beyond polarized debates and keep students at the center.Episode timestamps00:00 – Why the science of reading and science of math have become central to education debates.01:15 – What people really mean when they talk about the "science of" education—and why the definition of good research is so contentious.03:00 – Why disagreements over teaching methods are often really disagreements about what counts as credible research.05:45 – The history of the reading wars and math wars, and why today's education debates aren't as new as they might seem.07:30 – The central debate in math education: explicit instruction versus discovery-based learning.09:30 – What a 200-year-old math textbook and a 1934 research study reveal about today's debates over how students learn math.10:45 – Why there isn't a one-size-fits-all approach to teaching—and how educators can balance research-based guidance with individual student needs.13:30 – What happens when education research moves from academic journals into the media, classrooms, and education policy.16:00 – How teachers navigate competing research claims while drawing on their own classroom experience.19:00 – How educators and researchers can move beyond polarized debates and keep the focus on what's best for students.About Jon StarJon Star is a Harvard professor and educational psychologist whose work focuses on mathematics education, teaching, learning, and educational research.Listen to more conversations about education, research, and learning on the Harvard EdCast.

  • How Questions Can Transform Student-Centered Learning
    Mar 4 2026

    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.

  • Why Teachers Stay: What Research Reveals About Retention
    Feb 25 2026

    When Doug Larkin and Suzanne Poole Patzelt set out to study the relationship between teacher pay and retention, what they found surprised them.

    “Without fail, no matter what school we went to, what state we were in, that was always the number one response,” Poole Patzelt says. “We did nothing to put that at the top. That was far and beyond the number one reason why teachers stayed was because of who they were working with.”

    She adds, “We are relational organisms. We rely on relationships and other people.”

    Pay, Larkin explains, mattered but differently than we often assume. Teachers generally felt their compensation was adequate. What didn’t hold up was the idea that increasing pay would directly increase effort or retention. “It doesn’t fit that behavioral logic,” he says. “If we pay teachers 10% more, they’re going to work 10% harder. That’s not what was happening here at all.” Instead, what consistently surfaced were collegial cultures where teachers felt supported rather than scrutinized.

    In their new book, The Reasons Teachers Stay, they draw on a six-year longitudinal study of US schools, districts, and communities with high rates of teacher retention. In the districts they studied — spanning rural, suburban, and urban communities — a defining feature was a “real lack of teacher isolation.” Teachers shared resources. They kept doors open. Administrators fostered trust. Poole Patzelt notes that many of the top retention factors were intertwined: supportive leadership strengthened teacher relationships, and those relationships reinforced a broader culture of care.

    Each district operated within its own cultural and political context. Still, the strongest schools resembled what Larkin calls a “healthy ecosystem for teachers,” where induction went beyond onboarding and new teachers were not left in “sink or swim” environments.

    To make sense of these dynamics, Larkin introduces the “teacher embeddedness” framework, a way of understanding retention not as a single decision, but as the accumulation of many small connections. He shares a metaphor from elementary schools where principals are duct-taped to a wall as part of a reading challenge. One strip of tape does nothing. But layer enough pieces together, and they hold someone in place. “Each little thing you can identify,” he explains, “is another piece of tape that holds that teacher in place.”

    In this episode, they introduce the “teacher embeddedness” framework and gain better insight in why understanding what keeps teachers in the job might be the biggest shift a district can make.
