Instructional Systems Design
Instructional Systems Design involves is the practice of creating “instructional experiences which make the acquisition of knowledge and skill more efficient, effective, and appealing”. The process consists broadly of determining the state and needs of the learner, defining the end goal of instruction, and creating some “intervention” to assist in the transition. The outcome of this instruction may be directly observable and scientifically measured or completely hidden and assumed. There are many instructional design models but many are based on the ADDIE model with the five phases: analysis, design, development, implementation, and evaluation.
