Innovative strategies on teaching plane geometry using Geogebra software in secondary schools in Delta state

The article actualizes the problem of studying the transformations of geometric shapes in plane geometry and an effective, economical time visual representation of students of pedagogical universities (students of secondary schools - in classes with profound study of mathematics) on modern PC displays screens algorithms step by step tasks on the construction of the "circular" by inversion . Previously developed educational software (partially, the software GeoGebra) guarantees optimal quality rendering problems in the theory transformation "Inversion" and simulation of different visual situations and their dynamics and the structural features - precision, visibly clear visual-figurative of steps "analysis" and "building" in problems.

Perfect Continuity

The high-school subjects in mathematics are algebra and plane geometry. Changes in content or in method, if any, should be made for purposes that may be enumerated as follows: first, to secure more perfect continuity with the elementary school work; second, to prepare more perfectly for comprehension of mathematical science in general; third, to secure the pupil’s spontaneous interest by giving him as wide command as possible of such utilitarian problems as are likely to enlist his ambition.

Three Space

Geometry in secondary schools has evolved during the last few years so that the use of coordinates has become respectable and the use of vectors is beginning to gain acceptance. There still remains the basic problem of finding sufficient time to consider the topics from the traditional full year of plane geometry, an introduction to the geometry of three space, an introduction to coordinate methods of proof, and an introduction to vector methods of proof. There are also suggestions that many traditional topics of geometry be jettisoned and that other new approaches to geometry be included.
