The Guam Daily Post recently highlighted a STEM professional development program organized by McREL that gave teachers the opportunity to learn firsthand about marine robotics. During the three-day training, teacher teams constructed underwater remotely operated vehicles (ROVs) and used them in a competition to retrieve objects from the water, similar to a competition that their high school students participate in. The training was provided by Anne Tweed, a STEM consultant at McREL, and Jim McDonnel, a retired engineer who coaches school teams to compete in regional and international marine advanced technology education (MATE) ROV competitions.
