In this episode, we discuss two new studies from the Journal of the American Medical Association that provide concrete evidence on the cognitive costs of screen exposure during childhood. One study tracks social media's impact on cognitive performance in adolescents, revealing measurable deficits even with moderate use. The second study follows early childhood screen time and its association with academic achievement up to grade six. The findings underscore the need for early intervention, protective educational environments, and a critical re-evaluation of how digital tools are integrated into learning. Learn how the Walled Garden approach can preserve cognitive capacities essential for deep learning and democratic participation.

In this episode, we delve into Marshall McLuhan’s tetrad framework to analyze Alpha School, an AI-powered private school that promises efficiency and measurable mastery in learning. The discussion explores the implications of relocating educational authority from human teachers to algorithms, and scrutinizes the broader impact on democratic education and civic capacities. We question whether the model’s focus on operational efficiency undermines the vital social and argumentative practices needed in communal learning environments. Join us as we investigate the potential structural shifts in education and their profound consequences on public pedagogical practices.

Two weeks ago, the US Senate held a critical hearing addressing the state of K-12 education. This episode uncovers evidence-backed insights revealing that our education crisis is a broad structural shift, not just a temporary issue. With testimony from academics and district leaders, and global parallels, this discussion highlights the decline in reading and math performance, the entanglement with absenteeism, disengagement, and adolescent mental health, and the reshaping impact of new technologies. We explore practical imperatives for designing educational environments that prioritize cognitive development, and the need for a family-community-policy partnership to combat learning losses exacerbated by COVID disruptions. Tune in for a deep dive into the proposed Pedagogy of Cultivated Attention and actionable strategies to restore focused, meaningful learning in our schools.

Reimagining Education: The Power of Walled Garden Schools

In this episode, I explore the concept of 'Walled Garden' schools, educational spaces designed to foster deep cognitive development by reintroducing deliberate friction into the learning process. Drawing comparisons to historical scholarly environments, this approach prioritizes cognitive depth over digital convenience and promotes capacities essential for innovation and complex problem-solving. Through practical examples, I examine how physical and digital architectures can be restructured to support sustained attention, independent thinking, and genuine expertise. Join me as I delve into how these principles can address current educational challenges and better prepare students for an AI-dominated future.

In this episode, we delve into the ethical dimensions of attention in education, inspired by Simone Weil's claim that 'Attention is the rarest and purest form of generosity.' We explore how the commodification of attention in the digital age undermines students' cognitive and moral capacities, and question the effectiveness of the Marketplace Mirror model in preparing students for the future. This episode challenges the current educational paradigm, advocating for a thoughtful integration of technology that fosters sustained attention, critical thinking, and moral reasoning. Join us as we examine the foundational skills necessary for both academic success and democratic citizenship.

Rewired Minds explores how digital technologies are reshaping our kids' habits of attention. Drawing on insights from neuroscience and education, I examine the crisis of embodiment - what it means when learning becomes increasingly detached from the physical, lived experience that once grounded it.

This episode asks: What do we lose when screens mediate our classroom experiences? And how might we reclaim depth, presence, and wholeness in an age of distraction?
