“…Research shows that visualizations and simulations are a powerful and effective way for students to learn science concepts in learning environments with the suitable technology equipment (Gras, Cañadas & Ginovart, 2013;Zucker & Hug, 2008;Méndez, Lorenzo, Acosta, Torres & González, 2006;Heuer & Blaschke, 2001), and interactive applets provide powerful and flexible simulation tools (Canesin, Gonçalves & Sampaio, 2010). Today there are software tools available which allow lecturers, teachers and even students with very limited Java programming knowledge to create their own independent, high quality applets as an effective teaching and learning tool if used in an appropriate pedagogical setting, including virtual laboratories (Esquembre, 2004;Sánchez et al, 2005).…”
