Educational technology

Educational technology is the effective use of technological tools in learning. As a concept, it concerns an array of tools, such as media, machines and networking hardware, as well as considering underlying theoretical perspectives for their effective application.

Educational technology is not restricted to high technology. Also called e-learning, it includes an array of approaches, components, and delivery methods. For example, m-learning emphasizes mobility, but is otherwise indistinguishable in principle from educational technology.

Educational technology includes numerous types of media that deliver text, audio, images, animation, and streaming video, and includes technology applications and processes such as audio or video tape, satellite TV, CD-ROM, and computer-based learning, as well as local intranet/extranet and web-based learning. Information and communication systems, whether free-standing or based on either local networks or the Internet in networked learning, underlie many e-learning processes.

21st century

The 21st century is the current century of the Anno Domini era or the Common Era, in accordance with the Gregorian calendar. It began on January 1, 2001, and will end on December 31, 2100. It is the first century of the 3rd millennium. It is distinct from the century known as the 2000s, which began on January 1, 2000 and will end on December 31, 2099.

Transitions and changes

The first years of the 21st century have thus far been marked by the rise of a global economy and Third World consumerism, mistrust in government, deepening global concern over terrorism and an increase in the power of private enterprise. The longterm effects of increased globalization are not known, but there are many who are concerned about its implications. The Arab Spring of the early 2010s led to mixed outcomes in the Arab world. The Digital Revolution which began around the 1980s also continues into the present. The Millennials (born c. 1981-2000) having been born before the turn of the century give way to the rise of Generation Y & Generation Z in Western countries.
