Dr. Marta R. Ariza obtained her European Doctoral Degree in 2002 after carrying out some of her PhD work abroad and presenting her thesis on Organic Chemistry, both in Spanish and in English. She spent several years researching on the chemical properties of natural products with biological activity, but in 2005 changed her interests, focussing on science education. Currently, she is a lecturer at the Department of Didactics of Sciences in the University of Jaén. She has worked on the development of innovative pedagogical materials and methodologies for science education. Currently, she is especially interested in the potential of technological resources (simulations, modelling software, virtual laboratories, discussion tools, etc) to facilitate meaningful learning and the understanding of scientific concepts and procedures.
