Educational technology (ET) is abbreviated as EduTech or EdTech for a layman. Explicitly, ET is the instructional science amalgamating learning and technology.
Wikipedia define ET as Educational technology is “the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources”.
Learning is the perpetual and default attribute of human being, may be even Gods. Even God Thor learned that he will kill the serpent during Rangarök from his adventures and his lessons of life. Learning was verbal and experienced-based which later evolved into whiteboards via designated professionals called as teachers or educators. Contemporary world gets direction of technology in learning; computer is the mediator between learners and instructors. ET is the science facilitating learning encompassing e-learning, instructional technology, information and communication technology (ICT) in education, EdTech, learning technology, multimedia learning, technology-enhanced learning (TEL), computer-based instruction (CBI), computer managed instruction, computer-based training (CBT), computer-assisted instruction or computer-aided instruction (CAI. (again wikepedia said so).
In English proficiency test, every test is Computer-based including IELTS too now. Literally, proficiency tests have turned their faces from papers to computer screens as it must be cost effective for them (to conduct exam) and may be its ecologically-responsible initiative. We were in need of it; computer-mediated/assisted learning is the need of instructor more than a learner. From eternity, instructors were dependent on verbal resources more which has hampered the efficiency of instructors only. Provided, computer instructions using videos,images,speech to-text,screen readers increase the efficiency and efficacy of Instructors. We were dependent on teachers for the cognitive, emotional and professional development of our children and trainers/teachers single-handedly worked for it. ET is science for instructors, mostly.
