Educational technology is the development, application, and evaluation of systems and aids to improve the process of human learning. It is a systematic way of designing, implementing, and evaluating the total learning and teaching process using human and non-human resources to make instruction more effective. Educational technology applies both the traditional aids that are the focus of the course as well as non-material results like theories, principles, methodologies, strategies, and techniques of teaching to improve teaching and learning. It must be viewed in relation to teaching and the learning process so teachers understand how to make intelligent use of technological aids.
