Science and Education Publishing American Journal of Educational Research 2327-6150 4 16 2016 10 31 Designing an Experimental Prototype to Support Geometric Optics Concepts Comprehension 1179 1183 EN Juan Carlos Ruiz Mendoza School of Physics and Mathematics, University of Nuevo Leon, Mexico EDUCATION20164169 10.12691/education-4-16-9 2016 6 20 2016 10 5 2016 10 29 An experimental prototype to support the comprehension of concepts of Geometrical Optics was designed and assembled. The prototype might help teachers to explain Geometrical Optics concepts 'for example, the behavior of light passing through converging and diverging lenses and optical instruments', it is an inexpensive and accessible device that can be transported to classrooms. The expectation is that the equipment, properly used by teachers, would lead the students to understand abstract concepts of Geometrical Optics and thus motivate them to study this science.
