Educational Technology is the development , application and evaluation of systems , techniques and aids to improve the process of human learning .

Educational Technology is the application of scientific knowledge about learning and the conditions of learning to improve the effectiveness and efficiency of the teaching and training .

Educational Technology is the systematic way of designing , implementing and evaluating the total process of learning and teaching in terms of specific objectives based on research in human learning and communication and employing a combination of human and non-human resources to bring about more effective instruction .

•Jerome Bruner, working from a different perspective, devised a descriptive scheme for labeling instructional activities parallel to that Edgar Dale’s in 1966.
