Prensky's theory is interesting and his points are sometimes seems close to reality. He suggested that students today have changed significantly and that the school system is not suitable for new learners. Prensky describes the arrival of ICT as a discontinuity, an event so important that it created a gap between my parents' generation and my generation.
