The document summarizes a special session at the EDUCON 2020 conference on lessons learned from the eMadrid Network in simplifying educational technology. The eMadrid Network is a collaboration between six universities in Madrid, Spain that has organized seminars, workshops, and other events on educational technologies since 2010. The special session featured four presentations on making educational technology invisible through conversational agents, stealth assessment using sensors, and augmented reality. The key is using technologies like voice recognition, student data collection, Internet of Things sensors, and AR to enhance learning without requiring direct use of devices or explicit student awareness.
