Every year, thousands of educators come together at the ISTE Conference & Expo to discover new ways to learn with technology, and ISTE 2017 was no exception. In fact, it was a record-setting year for attendance.

The total number of attendees topped 15,000 for the first time. Throw in the expo hall staff, and you had more than 20,000 people immersed in learning, connecting and socializing at the Henry B. Gonzalez convention center.

Attendees came to San Antonio from every U.S. state and 72 countries. They enjoyed complimentary frozen treats, known as paletas, at registration and gobbled up plenty of tacos during meal breaks.

They sent 159,000 tweets, and many said on Twitter that the themes that resonated the most this year were digital equity, student — and teacher — voice and flexible and innovative learning environments.
