Do Turtle type educational robots have a role to play in High School? In general the use of these robots is in early years and primary schools. In High Schools the use of Lego and Vex construction type robots predominate. According to the Educational Robotic Application (ERA) Principles Turtle type robots can support the development of older students. This poster reports on a pilot project exploring this principle using the Roamer® robot. The project showed how robots can make a positive contribution to enriching a student’s mathematical experience and provided important insights on how to improve the organisation of robotic activities.
