Research and Collaboration

We have worked with professor Gilda Palis from the Math Department of the Pontifical Catholic University of Rio de Janeiro. The objective is to build a set of interactive applets that explores optimization problems as a method to conduct the study of functions in calculus courses.

We also had started a collaboration with Instituto Anísio Teixeira. The objective is to build a set of interactive applets that will support the books produced for high school students of Bahia State (EMAção Project).
