Perception is how we interpret sensation based on our experiences, intent, and expectations.   Perception is an important concept to consider in instructional design as learners can either view your curriculum in a positive or negative manner.  Negative perception can interfere with the learner’s ability to comprehend and absorb the information presented.   

It is important for the instructional designer to consider perception when designing their course of instructional.
