The usage of three dimensional (3D) virtual worlds in Mathematics Education not only eliminates the dependence of education on K-12 schools but also enables the subjects to be more concrete. The objective of this study is to create a mathematics laboratory by using the virtual classroom qualities of 3D worlds. In this lab, abstract mathematics…

This study was designed to investigate the impact of using computer-simulated (virtual ) manipulatives and hands-on (concrete) manipulatives on elementary students' learning skills and concepts in equivalent fractions. The researcher's primary interest was whether or not students who used virtual manipulatives would out-perform students who used…

Meaningful educational activities and cognitive tools might improve students' active involvements in the teaching-learning process and encourage their reflections on the concepts and relations to be investigated. It is claimed that usage of manipulatives not only increase students' conceptual understanding and problem solving skills but also…
