“Instructional Design is the systematic development of instructional specifications using learning and instructional theory to ensure the quality of instruction. It is the entire process of analysis of learning needs and goals and the development of a delivery system to meet those needs. It includes development of instructional materials and activities; and tryout and evaluation of all instruction and learner activities” (Definition: University of Michigan).
“It is strategic planning of a course. It is a blueprint that you design and follow. It helps us connect all the dots to form a clear picture of teaching and learning events” (Instructional Design: Raleighway).
