This document introduces an "HRL Cheat Sheet" which provides research-based recommendations for two areas: supporting youth interest-driven learning pathways, and strengthening the Hive as an infrastructure for innovation. The cheat sheet focuses on "pop-ups, hack jams, and maker parties" and provides 4 recommendations in each of 4 categories for participating organizations and those facilitating/hosting events. An activity is suggested for testing and providing feedback on the cheat sheet.
