Abstract
GeoBlock is a micro-world software tool for learning and teaching geometry, and has been prototyped on personal computers. It was designed according to the concept of direct manipulation of geometric figures under geometric constraints. A block is constructed to correspond to each complicated figure that is under geometric constraints, and it can be changed, re-used, and observed interactively on the computer's display. From practical use in classrooms, we are convinced that GeoBlock is effective in two phases of geometry lessons. One is the phase of discovering rules among geometric webs that the students have not yet studied. The other is the phase of assimilating geometrical facts that they have already studied. GeoBlock shows one way in which a computer can help students to learn geometry, and can help teachers to give persuasive geometry lessons.
