Problem posing as a way to mathematical literacy

In our work we search for ways of development of students' mathematical literacy. We aim at students' ability to utilize mathematics as a suitable tool for understanding of the world. Our aim is that students will be able to develop their knowledge. We stress not only solving of various problems.
