2. Technology in education is most simply and
comfortably defined as an array of tools that might prove helpful in
advancing student learning and may be measured in how and why
individuals behave. Educational Technology relies on a broad
definition of the word "technology." Technology can refer to
material objects of use to humanity, such as machines or hardware,
but it can also encompass broader themes, including systems,
methods of organization, and techniques. Some modern tools
include but are not limited to overhead projectors, laptop
computers, and calculators. Newer tools such as smartphones and
games (both online and offline) are beginning to draw serious
attention for their learning potential. Media psychology is the field of
study that applies theories of human behavior to educational
technology.
