The students will be able to identify situations in which either maps or GPS are the most appropriate tool for navigation guidance. This is important because online guidance systems are so prevalent that some children might deem paper maps as outdated or unnecessary. The IDM builds capacity by starting with identifying situations in which guidance is required. It then has students explore times when either electronic maps or paper maps are the most appropriate guidance tool. The formative tasks were chosen to give students the opportunity to interact with the various methods of guidance. The sources were chosen with the developmental level of the students in mind. This IDM will take 4-5 days to complete.
