DEVELOPMENT OF A NEW EDUCATIONAL DRAWING SOFTWARE FOR GEOMETRY INSTRUCTION

This project presents a new educational geometry drawing software called RISKO (Realistic Interface for Simulating a Kit of Objects). Following the direct manipulation, concrete, real world metaphor style, its interface features five drawing tools (triangle set, compass, pencil/eraser and a magnifying glass), which behave almost like their real counterparts. Due to its characteristics, RISKO is intended to be very intuitive, not requiring any operating instructions and being capable of implementing all compass-and-ruler geometric constructions, while training the apprentice in the correct ways of using real drawing instruments.
