The Most Likely Machine prototype is a digital learning experience that introduces pre-teens to important ideas around digital literacy, starting with the foundation of so much of our digital world: algorithms. Designed for both individual exploration and to supplement classroom curriculum, the Most Likely Machine learning experience helps pre-teens understand algorithmic bias and recognize its impact, enabling them to grow into more conscious, savvy, and responsible consumers, creators, and digital citizens. Algorithmic literacy is an essential skill that sits at the intersection of math, social studies, civics, and media literacy. While many pre-teens are taught the concept of algorithms as foolproof mathematical or computer science tools, we saw an opportunity to develop an experience that examines the ethics and justice of algorithms.
