Mobile learning involves using mobile technologies to enable learning anywhere. Examples of mobile learning projects include the MANOLO project in 2006 and the Ambient Wood project in 2004. The Ambient Wood project augmented a physical environment with digital elements to support children's playful learning and reflection. Mobile technologies can sustain student engagement and collaboration when used for instructional purposes in education. Many students and administrators believe that tablets are an essential part of schooling. Mobile learning supports teachers by offering flexible learning locations and encouraging learning outside the classroom with technologies like tablets and phones. The mobile technology is just one part of interactions that cross boundaries and involve both mobile and fixed devices, with the focus on weaving mobile interactions into pedagogical experiences.
