Abstract

3D visualization is an innovative tool for teaching abstract concepts in Chemistry, such as chemical bonds and molecular geometry. Misconceptions, such as misinterpretation of polarity, negatively affect learning. In this paper, through tools such as Tinkercad, we will present how students explore 3D models that facilitate the understanding of electron density. Data from the questionnaires completed by students show an improvement in their interest and knowledge for the subject , the construction of knowledge by the student was supported (Μικρόπουλος, 2006˙ Μικρόπουλος & Μπέλλου, 2010) while visualization seems to connect macroscopic, microscopic and symbolic levels, enhancing the learning experience.
