This project integrate geography and writing with technology. Individuals/students agree to take kids from a particular school (Patriot Kids) on field trips/vacations and upon return, e-mail a picture from the vacation and an article telling the school about the trip. These stories and pictures appear on their 'Traveling With the Patriot Kids' blog.

A Missouri teacher, Ms. Venosdale and her students bring the world -- virtually -- through a project called KnowGlobe. They regularly talk with students on other continents while at the same time learning about time zones, cultural differences, global weather patterns, and the state of education worldwide. If they come up with a project question that requires the expertise of an astronaut, space engineer, or Egyptologist, they ask their teacher to "tweet it out" and track down an expert for a Skype interview.

Matthew Stoltzfus, an OSU chemistry professor, teaches about 350 students in one lecture hall and uses social media helps him to track students' progress in "real time." Students bring cellphones or laptops to class to answer questions by messaging in to a number given to them, instead of using the traditional clicker in the class.

Twitter is also used in Stoltzfus' classes. He gives his students his personal Twitter handle, and they decide whether to follow him from their accounts.

Grade 1/2 students in Kristen Wideen's class study tadpoles and frogs. In her class, she incorporates video conferencing, blogging, creating videos and books, teaching and learning from other peers in the classroom. Her students have shared math stories with a class in Iowa and frog data with a class in Singapore. They engage in social media as part of their daily routine by checking their class Twitter account, blogging during literacy centers, and checking on their tadpoles via live web cam.
