Chapter 2.1 - Introduction to ID Selection Method
Instructional design (ID) also known as Instructional System Design (ISD) is the art and science of creating an instructional environment and materials that will bring the learner from the state of not being able to accomplish certain tasks to the state of being able to accomplish those tasks.
The approach to instructional design is effective because it forces attention to what is going to be learned (learning objectives) and what must already be known prior to the learning transactions. Once the learning objectives have been identified, they are progressively sequenced from lower order to higher order learning. These elements are essential if learning is to be effective under all conditions. Therefore, when instruction is designed based on a system instructional design model, the end result is an effective instruction regardless of who is teaching.
Instructional systems design combines knowledge of educational theory and practice with appropriate technologies to enable learning. It involves choosing appropriate technologies and designing interactions that promote effective and efficient knowledge transfer. The effectiveness of any instructional material depends also upon an appropriate planning, hence the instruction has to be planned if it is to be effective and designed in some systematic way.
