What Is Instructional Design?
"In short, instructional design is the systematic process by which instructional materials are designed, developed, and delivered. The terms instructional design, instructional technology, learning experience (LX) design, educational technology, curriculum design, and instructional systems design (ISD), are often used interchangeably" (Instructional Design Central).
Instructional Systems Design is the theoretical underpinning of the field, while cognition and learning theory also contribute to the theoretical base. IDT is a systematic field, focusing on product, process, and environment.
