Professional Development of Mathematics Teachers in the Age of I4.0
The 21st century has witnessed the development of the fourth industrial revolution that means cutting-edge technologies including artificial intelligence and the internet of things. The special quality of this epochal revolution lies in a rapid acceleration of the speed of change, never seen before. This is happening at the most challenging time ever faced by our species, due to existential threats. This scenario begs big questions to professionals in the field of mathematics education. Can mathematics education contribute to build a better world? The chapter reports on a participatory research conducted by a researcher in mathematics education together with 11 mathematics teachers. Therefore, the research benefits from a double point of view, coming from different cultures so gaining a double verisimilitude, which makes the results acceptable for all the professionals involved.
