Educational technology in the 21st century should focus on student-centered learning, collaboration, and contextual learning. It can support this new approach in three key ways: by developing 21st century skills through comprehensive technology use, innovating teaching and learning through technology, and creating robust education support systems. Important functions of educational technology include improving teaching and learning, analyzing the teaching-learning process, enhancing educational goals, training teachers, developing curricula and teaching materials, and identifying ways to improve communication and help disadvantaged students.
