On August 4, Scientific American hosted its third annual STEM Executive Summit at the New York Academy of Sciences in collaboration with Macmillan Education and Nature. This year's theme was "Building the 21st Century Learner." The meeting brought together members of the research and education communities with policy and business leaders to help advance a bold new vision for using science to transform how we teach our children and nurture scientific talent. Participants shared insights from the event throughout the day on social media. Below is a Storify collection of some of the posts on Twitter. We hope you will enjoy them and add your own thoughts about how to moderinze our educational systems.
