welcomes education writer and author Natalie Wexler to the podcast to discuss her latest work and the evolving conversation around explicit instruction and the "Science of Reading." While the movement has successfully brought phonics to the forefront, Wexler argues that too narrow of a focus ignores the lessons of the Science of Learning. Wexler notes that the "Science of Reading" is often misunderstood as being synonymous with phonics. While foundational skills are non-negotiable, she explains that the "Mississippi Miracle" and other literacy success stories are incomplete...

welcomes neuroscientist and acclaimed author Jared Cooney Horvath to dissect his new book, The Digital Delusion, which provides a rigorous, evidence-based critique of edtech. Horvath doesn’t mince words, arguing that the majority of student-facing, internet-connected devices should be removed from schools. He reveals that over 60 years of consistent data supports his claim that the integration of digital tools is fundamentally detrimental to effective learning. This isn’t a Luddite’s complaint; it’s a detailed exploration of the Neuroscience of Learning. The harm is...
info_outlineIs the core of teaching history about memorizing history facts, or is it about critical thinking? And what is the role of knowledge-rich inquiry in the history classroom?
Drew Perkins is joined by history educators Lauren Brown, Jonathan Dallimore (author of Teaching History: A Practical Guide for Secondary School Teachers), and Professor Aaron Astor for a frank, dialectic conversation on these essential questions. They discuss the necessity of foundational knowledge, how to promote historical thinking, and the biggest threats to historical understanding in the age of AI and social media.
Links & Resources Mentioned In This Episode
This deep dive into history pedagogy covers:
- Why college students are showing up “fact-deficient” and the need for better long-term memory retention through context.
- The difference between simple chronology and the power of periodization as a critical thinking tool.
- Why the fundamental historical critical question is “so what.”
- Bridging the gap between knowledge building and inquiry-based learning to equip students with “reality-based community practices.”
- The argument for why historiography (understanding different interpretations and debates) is a crucial form of shared cultural knowledge.
Key Themes & Time-Stamped Highlights
(00:14:18) The Problem of Forgetting: Professor Astor notes that college students often lack basic knowledge, not because they were never taught, but because they forgot previously learned information. He emphasizes the need for repetition and context to make facts “stick”.
(00:18:17) The Multiplication Analogy: The panel agrees that some foundational facts, like multiplication tables in math, must be fluent to prevent cognitive load when performing higher-level tasks, such as understanding complex military strategy or migration patterns in history.
(00:23:07) Efficiency of Explicit Instruction: Jonathan Dallimore explains that concrete, explicit instruction (such as teaching geography on a map) is necessary to efficiently inject context, preserving limited class time for richer, deeper historical conversations (inquiry).
(00:27:37) The Case for Foundational Facts: Lauren Brown supports teaching foundational facts (like the 50 states) at a young age to build knowledge systematically and improve overall literacy and comprehension of diverse texts.
(00:36:56) Context is Key to Memory: Drew Perkins points out that facts are more likely to be retained in long-term memory if they are put in context with other information (e.g., connecting a state’s location to regional dynamics or Civil War loyalties).
(00:45:08) Chronology vs. Periodization: Jonathan Dallimore champions periodization (breaking history into three or four manageable phases) as a more effective tool than simple chronology. He argues that periodization is not only concrete but also serves as a critical tool for later interpretation and debate.
(00:53:10) Knowledge Prevents “Post-Truth Nonsense”: The panel stresses that building a sufficient factual architecture is crucial to prevent historical discussions from devolving into unsupported, opinionated “post-truth nonsense”.
(00:56:48) The “So What” Question: Aaron Astor identifies the fundamental critical question in history as “so what” — encouraging students to understand why a particular piece of information matters and how it is connected to a bigger force or theme.
(01:07:09) Knowledge as an Indicator, Not the Aim: Drew Perkins introduces Grant Wiggins’s idea that “knowledge is an indicator of educational success, not the aim,” emphasizing the value of what a student can do with the knowledge (i.e., critical thinking and making connections).
(01:19:02) The Importance of Historiography: Jonathan Dallimore argues that rich cultural knowledge should include an understanding of the big historical debates and interpretations (historiography) to help students contextualize information encountered on social media.
(01:21:53) Navigating the Modern Information Landscape: Aaron Astor discusses how AI and social media (the “anarchy of takes”) have destabilized the architecture of information, making it imperative for history teachers to inculcate reality-based community practices to discern fact from fiction.
(01:34:01) The Goal: Think Historically: Aaron Astor concludes that the ultimate goal of history education is for students to “think historically” about their worlds and their times.
