Cabrillo is a tool for the creation of environments for exploration. From the student-designer's point of view, Cabrillo allows cards to be linked together intelligently without any programming. All branching is defined by pointing and clicking. The HyperTalk language is never visible. From the player's point of view, Cabrillo allows the development of games that are easy to move around in, and which are tied to curriculum by their being grounded in historical reality.
Navigation is accomplished by clicking on a compass.
Maps and a reference manual are available at the click of an icon. Results Students in the first year of the project produced extensive microworlds in all of the five scenarios. When the project began, six weeks had been allocated in the calendar to its completion. As week six approached, it became clear that more time was needed, and the project was extended through the next six week term. Teachers were somewhat tired of the microworlds project in this last phase, but doggedly brought it to completion.
