The first four books in a series of young adult science and adventure novels by Angela Posada Swafford (00-01) were published in summer of 2007. The series, Los Aventureros de la Ciencia (The Adventurers of Science), is designed to educate young adults about science. One of the four books within the series, Dinosaurios Sumergidos (Sunken Dinosaurs), was chosen by the Ministry of Education of Mexico to be included in the libraries of its public schools for 2007. See the series blog here.
Update 2/9/09: The Costa Rican government is using two of the books in the Los Aventureros de la Ciencia series as a science teaching tool for the public schools. They are designing a whole new pedagogic curriculum based on the two novels and Angela will be teaching a series of seminars to train the public school teachers in the use of those novels”
