All of these breakout sessions promise to engage participants actively and to leave you with ideas or resources that you can implement in your own teaching. These sessions address a wide range of topics from data science and multivariable thinking to undergraduate research and teacher preparation. We have scheduled four sets of breakout sessions, with eight sessions to choose from in each time slot. We hope that the breakout topics are so enticing that you will face tough decisions about which to attend in each time slot. In anticipation of this difficulty, eight of the breakout sessions (marked with * in the program) will be repeated in a second time slot.
