Can people learn in the AI era? Ashley and Cat think so. We talk about Ashley's experiences teaching programming and co-designing WITH students (not against them) to create shared classroom norms around AI, and about the metacognitive skills that Cat is sharing with the software teams and developers she works with to bring a "dynamic textbook" approach to using AI to build understanding, not degrade it. Cat's Learning Opportunities Claude Skill, with a scientific reference list to the effects we also talk about in this episode, can be found here:https://github.com/DrCatHicks/learning-opportunitiesCat also wrote a recent piece about the complexity of measuring the impact of AI in Software Organizations: https://www.fightforthehuman.com/how-not-to-measure-the-roi-from-ai-in-your-software-organization/Learn more about Ashley:https://ashleyjuavinett.com/https://mastodon.social/@analog_ashleyashleyjuavinett.bsky.socialLearn more about Cat:https://www.drcathicks.com/https://mastodon.social/@grimalkinagrimalkina.bsky.social

First of all, in this episode you'll learn why Ashley has shipped ONE THOUSAND COCKROACHES through the mail. Second of all, Ashley shares about getting scientists to tell stories, taking risks to share knowledge, and doing science communication in places that don't look like a university campus. We talk about work with the following amazing organizations:Guerilla ScienceSASSY San DiegoCaveat NYCIf you want more science storytelling in your life, please check out The Story Collider. The recording kits we sent to students were made by Backyard Brains.If you're curious about Ashley's neurobiology lab class, you can learn more about it here.Ashley also wants to give a shout out to the amazing UC San Diego staff who made shipping cockroaches during a global pandemic possible, and who still maintain the ongoing roach colony, occasionally even feeding them donuts.Learn more about Ashley:https://ashleyjuavinett.com/https://mastodon.social/@analog_ashleyashleyjuavinett.bsky.socialLearn more about Cat:https://www.drcathicks.com/https://mastodon.social/@grimalkinagrimalkina.bsky.social
