Educational technology is a field of study that investigates the process of analyzing, designing, developing, implementing, and evaluating the instructional environment and learning materials in order to improve teaching and learning. It is important to keep in mind that the purpose of educational technology (also referred to as instructional technology) is to improve education.

Instructional technology can also be seen as a process of solving educational problems and concerns, which might include motivation, discipline, the drop-out rate, school violence, basic skills, critical thinking, and the whole list of educational concerns. First, the problem is identified, an analysis of the factors of the problem is made, and possible solutions to the problem are presented. Then, the student population and the curriculum are analyzed. The next step is to select the most appropriate instructional strategies for the particular situation. Next, instructional materials and resources are selected that are suitable for the curriculum and the mode of instruction chosen. Finally, the program is implemented, evaluated, and revised as needed in order to meet the stated goals for school improvement.

The learning materials today have greatly expanded because of the various technological advances. Instructional materials include more conventional materials, such as the blackboard, overhead projectors, televisions, VCRs, overhead projectors, slide projectors, and opaque projectors, as well as newer materials, such as the computer, various software applications, LCD projectors, camcorders, digital cameras, scanners, the Internet, satellite, interactive TV, audio and video conferencing, artificial intelligence, and so on.
