    Happiness economics and emerging tech, Kiera Peltz on building access at scale

    In this episode of Chalk and Code, host Jill Foley sits down with Kiera Peltz, Founder and CEO of The Coding School, to explore how happiness economics, equity, and emerging technology education are deeply connected. Kiera shares her journey from studying happiness at Brown to launching The Coding School from her college dorm room at 19, driven by a belief that access to technical skills is foundational to agency and wellbeing. She reflects on global perspectives gained in China, early validation from school leaders, and the urgency she felt to rethink how and when students are introduced to computer science. Throughout the conversation, Kiera unpacks what equity looks like in practice, from high-touch retention strategies to designing programs that work for students learning on mobile devices. She also shares how bold experimentation led to scaling quantum computing and AI education, partnerships with IBM, and earning a $3M Department of Defense grant. The episode closes with a forward-looking view of why depth, not just awareness, is essential in preparing students for a rapidly evolving future. Key Moments 01:08 What happiness economics is and why it matters 04:29 Education, skill-building, and control over one’s future 06:13 Global perspectives and the urgency to act early 09:16 Early validation from a school principal 10:11 The Coding School’s access-focused program model 13:38 Equity at scale, funding, and retention through human connection 19:06 Dropout patterns and shifting from in-person to online learning 24:27 Introducing quantum computing and pushing past skepticism 26:57 Scaling during the pandemic with IBM 30:32 Turning outcomes into a $3M Department of Defense grant 32:17 Designing for mobile learners and listening with humility 37:35 What’s next for The Coding School and emerging tech education 42:58 Why tech literacy matters for every future path 44:57 “It’s not on the students, it’s on us.” Why You’ll Love This Episode This episode reframes emerging technology education as a human-centered endeavor. Kiera makes a compelling case that rigorous STEM learning can and should be accessible to every student, and that retention, personalization, and humility are essential parts of equity.

    AI, open source, and the new entry-level: Tyler Menezes on preparing students for tech careers

    In this episode of Chalk and Code, host Theron Davis sits down with Tyler Menezes, CEO of CodeDay, a nonprofit that creates welcoming, project-based experiences for underserved students to explore a future in technology through 24-hour coding events and open source–focused internships. Tyler shares his journey from Y Combinator–backed startup founder to nonprofit leader, and why CodeDay is obsessed with helping students build real things, not just pass tests. He breaks down how experiential learning, mentorship, and open source contributions can close the gap between “I have a degree” and “I can actually do the work” in an AI-saturated job market. From rethinking hackathons as creative entry points for beginners, to using open source as a verifiable micro-credential, to confronting how AI is eroding traditional entry-level roles, this conversation looks squarely at what students really need to become workforce-ready in computer science and beyond. Key Moments 01:09 Tyler’s journey from college dropout and YC-backed founder to nonprofit CEO 02:32 Why CodeDay started with students who had little or no prior interest in coding 03:44 Using creativity, games, art, and music to make coding feel fun and accessible 04:25 Where CodeDay sits on the “systems vs. individual learner” continuum 10:19 How teachers find CodeDay and why there is a learning curve on both sides 26:14 New grads hiring is down, mid/senior hiring is up: what that means for CS programs 27:55 Rethinking the value of a CS degree in an AI-driven labor market 28:32 AI as the new “junior engineer” and the shrinking space for entry-level roles 38:47 The Open Source Fellowship and supporting students over multiple years 40:00 How CodeDay measures engagement, readiness, and long-term impact 41:04 Using application, interview, and offer data as a near-term signal of employability 42:07 Classifying student standups with AI to find who is stuck and intervene early Why You’ll Love This Episode If you care about how to actually get students from “I took the class” to “I can get hired and contribute on day one,” this episode is a must-listen. Tyler challenges the assumption that more content or more credentials automatically lead to opportunity, and instead argues for experiences that build independence, curiosity, and real-world problem solving.

    Human-in-the-loop AI tutoring: Raj Valli on guaranteed learning outcomes

    In this episode of Chalk and Code, host Theron Davis sits down with Raj Valli, Founder and CEO of Thinkster Math, an AI-driven tutoring company that blends patented AI with human coaches to deliver measurable outcomes in math learning.Drawing on experience across 12 industries and decades of nonprofit work in education, Raj unpacks why so many students still struggle with foundational math and what it really takes to design systems that reliably close learning gaps instead of just delivering content. From AI-powered diagnostics that probe “wells of knowledge” to deep analytics that surface patterns like “this student struggles with two-digit multiplication when numbers end in 9,” Raj explains how Thinkster uses data, instructional design, and human tutors together to guarantee outcomes rather than hope for them. He also explores the limits of today’s AI, arguing that most models still rely on crystallized intelligence, while truly transformative learning and innovation depend on human fluid intelligence. If you care about how AI, behavior science, and human relationships can be combined to help learners “learn better, faster, sooner,” this conversation offers a practical, grounded look at what high-accountability edtech can be Key Moments 00:00 Welcome to Chalk and Code and introduction to the episode 01:22 Raj’s journey across 12 industries and nonprofit education work in India 02:21 The “airlines” analogy and the shocking reality that 40–50% of students are failing in math basics 04:14 Why “passionately curious” is the mindset behind Thinkster’s constant iteration 07:08 Positioning Thinkster as a learner-centric, “cradle to grave” solution rather than just a K–12 tool 09:55 The five key nodes: AI, data and analytics, curriculum design, human-in-the-loop tutoring, and behavior 13:48 Why behavior, discipline, and intrinsic motivation are as critical as content and technology 16:10 Rethinking diagnostics: using AI “dipsticks” to find where a learner’s true starting point should be 19:12 How probabilistic assessment works and why diagnostics must feel confidence-building, not punitive 23:24 Designing for emotion as well as intelligence so learners feel more confident as they progress 27:08 Giving tutors real insight, not just data: “this student struggles with numbers ending in 9” 29:44 AI as “actual intelligence”: why human judgment is still essential for context and bias 31:49 Crystallized vs. fluid intelligence and why Raj is skeptical of claims that AI will fully replace humans 35:31 Shifting from delivery of knowledge to adaptive use of knowledge as the core goal of education 36:40 Why adaptive knowledge and real-world application matter more than memorization Why You’ll Love This Episode This episode challenges the default assumptions behind most learning technology. Instead of starting with “What can AI do?”, Raj starts with “What does the learner need, right now, to move forward?” and builds from there. You’ll hear how Thinkster: Uses AI diagnostics and behavioral data to find each learner’s true starting point and close gaps with precision.Combines human tutors, curriculum design, analytics, and behavior science into a single, outcome-focused model. Gives tutors actionable insights instead of dashboards for their own sake, so every session is targeted and high impact.Frames AI as a powerful tool for crystallized intelligence while insisting that fluid intelligence, context, and values remain deeply human responsibilities.Re-centers education around adaptive knowledge: not just what students can recall, but what they can do with what they know.Connect with Raj ValliLinkedIn: https://www.linkedin.com/in/rajvalliThinkster Math: https://hellothinkster.com/ Connect with UsCompany’s LinkedIn: https://www.linkedin.com/company/flexion-incCompany Website: https://flexion.us/ If this conversation sparked a new idea or challenged your assumptions, share this episode with a colleague and subscribe for more thoughtful discussions at the intersection of learning, leadership, and educational technology.
