Educational technology is defined as a systematic process of applying scientific knowledge to improve learning and instruction. It can be applied in both formal and non-formal education. In formal education, technologies like visual aids, computers, and the internet are used. These include projectors, smart boards, and classroom computers. In non-formal settings, computer-assisted learning, digital learning resources on the web, computer-mediated communication tools, and computer-aided assessment are applied using technologies like email and videoconferencing. The most effective approach integrates these various educational technologies to enhance the learning process.
