In an article appearing in today’s issue of EOS, Zackary Johnson and Dave Johnston discuss how smartphones are changing the way geoscience is taught. Smartphones and other personal electronic devices are now allowing students and the public to measure ocean color, record species encountered, visualize environmental acoustics, document the distance between landforms, and more, all through a touch of a button. Similar to the “tricorder” from Star Trek—a fictitious hand-held device for scanning, recording observations, and analyzing the environment—mobile devices put data collection, visualization and learning literally in the palms of people’s hands.
