The move-up-down-left-right tutorials promoted by schools came from tech-backed nonprofit Code.org and its tech giant partners and have been taught over the years by the likes of Bill Gates, Mark Zuckerberg, and President Obama, as well as characters from Star Wars, Disney Princess movies, and Microsoft Minecraft.
