Educational technology is defined by the Association for Educational Communications and Technology as “the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources”.[1]

Educational technology refers to the use of both physical hardware and educational theoretics. It encompasses several domains, including learning theory, computer-based training, online learning, and, where mobile technologies are used, m-learning.[2] Accordingly, there are several discrete aspects to describing the intellectual and technical development of educational technology:

• educational technology as the theory and practice of educational approaches to learning
• educational technology as technological tools and media that assist in the communication of knowledge, and its development and exchange
• educational technology for learning management systems (LMS), such as tools for student and curriculum management, and education management information systems (EMIS)
• educational technology itself as an educational subject; such courses may be called “Computer Studies” or “Information and communications technology (ICT)”.

Technology in education and education technology are two different concepts which deal with the use of technological tools and innovative educational strategies respectively.

Richey defined educational technology as “the study and ethical practice of facilitating learning and improving performance by creating, using and managing appropriate technological processes and resources.”[3] The Association for Educational Communications and Technology (AECT) denoted instructional technology as “the theory and practice of design, development, utilization, management, and evaluation of processes and resources for learning.”[4][5][6] As such, educational technology refers to all valid and reliable applied education sciences, such as equipment, as well as processes and procedures that are derived from scientific research, and in a given context may refer to theoretical, algorithmic or heuristic processes: it does not necessarily imply physical technology. Educational technology is the process of integrating technology into education in a positive manner that promotes a more diverse learning environment and a way for students to learn how to use technology as well as their common assignments.
