Educational technology refers to the use of scientific methods and technological tools to improve the learning process. It involves developing, using, and evaluating systems, techniques, and aids to enhance teaching practices and improve learning outcomes. Educational technology aims to optimize learning by systematically arranging instructional content and applying technical tools. It allows analysis of both teaching and learning to enhance educational goals and keep pace with a changing world.
