Data collected were analyzed using mean, percentage, standard deviation and t-test for paired observations. Results revealed that junior high school students' attitude towards mathematics and technology gained a relative increase as influenced by the usage of the Geometer's Sketchpad. Furthermore, the Geometer's Sketchpad showed a positive impact on students' achievement in Geometry as indicated in the increase of their posttest scores. The researcher then recommends that mathematics teachers may consider utilizing technological tools like the Geometer's Sketchpad in discussing lessons in Geometry and other mathematics subjects to improve not only their students' mathematics achievement but also for students' attitude towards mathematics and technology.
