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.\nIf 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\nKey Moments\n\n00:00 Welcome to Chalk and Code and introduction to the episode\n01:22 Raj’s journey across 12 industries and nonprofit education work in India\n02:21 The “airlines” analogy and the shocking reality that 40–50% of students are failing in math basics\n04:14 Why “passionately curious” is the mindset behind Thinkster’s constant iteration\n07:08 Positioning Thinkster as a learner-centric, “cradle to grave” solution rather than just a K–12 tool\n09:55 The five key nodes: AI, data and analytics, curriculum design, human-in-the-loop tutoring, and behavior\n13:48 Why behavior, discipline, and intrinsic motivation are as critical as content and technology\n16:10 Rethinking diagnostics: using AI “dipsticks” to find where a learner’s true...","thumbnail_url":"https://img.transistorcdn.com/3axgf2SSmiMFxyolDWwFFSNcakWI6mxP4Mv3QdmXP4A/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS80Zjhk/Y2I1ODg2MjlhZTQx/OWYyM2Q2NzFlYjBl/ZGE1ZS5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
