The Effectiveness of an Enrichment Program Using Dynamic Geometry Software in Developing Mathematically Gifted Students' Geometric Creativity in High Schools

Impact d'un programme d'enseignement enrichi utilisant un logiciel de géométrie dynamique, pour développer la créativité géométrique des élèves à haut potentiel dans le secondaire

Résumé

In this study, we 1. identify the principles of preparing a suggested enrichment program in Euclidean geometry using dynamic geometry software (Cinderella) to develop the mathematically gifted students' geometric creativity in high schools; 2. develop an enrichment program based on the identified principles; 3. investigate the effectiveness of this program by testing it with high school students. A geometric creativity test (GCT), was developed and a grading method for assessing the mathematically gifted students geometric creativity was established. The material was tested with a group of 7 mathematically gifted students in the Landesgymnasium fur Hochbegabte (LGH), a public high school for highly gifted and talented students in Schwabisch Gmund (Baden-Wurttemberg, Germany). The students came from 11th (5), 10th (1) and 9th (1) grade, two of them were male, fi ve female. In the study, the researcher used a one-group pretest design. In this context the GCT was administered to students as a pretest at the beginning of the study; then the suggested enrichment program was introduced to them in 12 weekly 90-minutes sessions during the first semester of the academic year 2008/09. The students retook the GCT as a post-test at the end of the study. The results indicated there were statistically signi cant di erences between the mean ranks of the subjects' scores on the pre-post measurements of the geometric creativity test and its subscales in favor of the post measurement. The results also revealed that the suggested enrichment program was signi cantly e ective in developing geometric creativity as a whole ability and its four sub-components { uency, exibility, originality, and elaboration.

Impact d'un programme d'enseignement enrichi utilisant un logiciel de géométrie dynamique appelé Cinderella, afin de développer la créativité géométrique. Un test de créativité géométrique a été développé et permet de valider un impact positif d'un programme spécifique utilisant le logiciel Cinderella auprès de 7 élèves à haut potentiel dans le secondaire.
