Educational technology involves the use of various technological tools in learning, covering media, machines and network hardware. It goes beyond high-tech, incorporating e-learning, educational technology, ICT in education and other labels. The field draws on theoretical perspectives such as instructional theory, learning theory, and educational psychology. Media types such as text, audio, images, animation, and streaming video, along with technologies such as CD-ROM and computer-based learning, contribute to educational technology. It applies to a variety of settings, including homes, schools, and businesses, and supports synchronous or asynchronous, self-paced or instructor-led learning, often in blended formats.

Educational technology, per Richey, focuses on ethically studying and applying methods to enhance learning and performance through appropriate technological processes and resources. Instructional technology, as defined by AECT, involves the theory and practice of designing, developing, utilizing, managing, and evaluating processes and resources for learning. This encompasses valid and reliable applied education science, including equipment, procedures, and processes derived from scientific research, without exclusively implying physical technology.
