Research has consistently shown that interactive and collaborative group learning, compared to traditional methods, produce greater learning and individual achievement. Learning can be fun, but for that, students need to be on scene and not just spectators. This paper presents a framework that handles the creation of georeferenced multisensory information, placing the content creation control in the hands of junior explorers-the children. Mobile sensors spread across the exploring area, provide georeferenced environment information such as air temperature and humidity. Using multimedia (video, image, sound and text) teachers can bring the outside world into their classroom and share it with other classrooms across the globe. Having schools' budgets in mind, when using this framework only content exploration-using Google Earth-requires Internet connection, that is, content creation can be made anywhere without any costs.

Mobile devices such as autonomous vehicles are equipped with sensors and actuators that provide means for computation to react upon spatial information and produce effects over the environment. The spatial behavior of these systems is commonly specified at the physical level, e.g., GPS coordinates. This puts the responsibility for the correct specification of spatial behaviors in the hands of the programmer. We propose a new paradigm named logical-space programming, where the programmer specifies the spatial behavior at a logical level while the runtime system is in charge of managing the physical behaviors. We provide a brief explanation of the logical-space computing semantics and describe a logical-space runtime system using bigraphs as logical models and bigActors as computing entities. The physical entities are modeled as polygons in a geometrical space. We demonstrate the use of logical-space programming for specifying and controlling the spatial behaviors of vehicles and sensors performing an environmental monitoring mission. The field test consisted of an Unmanned Aerial Vehicle and GPS drifters used to survey an area supposedly affected by illegal bilge dumping.
