Summary/Abstract: This article discusses the advantages of teaching-learning Geometry with the help of the new educational technologies to motivate students and undergraduates, which may lead to building focus, interactivity and feedback during lessons.The 3rd-year students from the Department of Mathematics, “Vasile Alecsandri” University of Bacău, also attending the courses of the Pre- and In-Service Teacher Training Department, have experimented the relevance of the new technologies in teaching and learning Geometry, by applying a new approach to the design and conduct of a lesson of Geometry.The teaching practice conducted at “Octavian Voicu” Middle School has shown that the use of AEL laboratories and dynamic mathematical software in teaching and learning generates improved results for students in Geometry lessons, as well as in the National Evaluation test.The research tests, applied to two 8th-grade classes, demonstrated the efficiency of teaching Geometry by using computers in solving problems and promoting Geometry knowledge, building active thinking and competences, as well as skills in representing plane and space geometrical figures.
