In other words, get the learner into a task quickly, and then provide content instruction through the feedback.

So, to me, the most important skill an instructional designer can have is being able to apply instructional strategies. To know when to use a mnemonic and when to use an analogy. When to model the behavior to be learned and when to provide a check list. When <a href="http://en.wikipedia.org/wiki/Constructivism_%28learning_theory%29" target="blank">Constructivism </a>is a good theorietical underpinning for a topic and when a <a href="http://en.wikipedia.org/wiki/Cognitivism_%28psychology%29" target="blank">Cognitivism</a>-based approach is necessary. <br> <br> Instructional designers add value by serving as catalyst who accelerate the process of learning for individuals.

The most commonly discussed disabilities affecting website accessibility are sight and hearing impairments. These specific impairments encompass 6.8 percent of the population age 15 years and older – and climb to encompass 21.3 percent of the population when you look specifically at the population over 65, according to the 2005 report. Eight-point-two percent of this same population is listed as having difficulty grasping objects– which affects the use of a mouse.

Numerous contradictions of cognitive load theory’s predictions have been found, but with germane cognitive load, they can still be explained away.&nbsp; de Jong does not use this term (unfalsifiable) but instead states that germane cognitive load is a <em>post-hoc</em> explanation with no theoretical basis: “there seems to be no grounds for asserting that processes that lead to (correct) schema acquisition will impose a higher cognitive load than learning processes that do not lead to (correct) schemas” (2009).

2. <span style="text-decoration: underline;">Poor external validity of lab-based studies</span>.&nbsp; Moreno doesn’t touch on something in the de Jong article – the fact that most cognitive load (and multimedia learning) studies are conducted in labs that “includes participants who have no specific interest in learning the domain involved and who are also given a very short study time” (de Jong, 2009), often only a few minutes.&nbsp; Quite a number of findings from these studies have not held up as strongly when tested in classrooms or real-world scenarios, or have even reversed (<a href="http://www.txwes.edu/professionaldevelopment/materials/Multimedia%20Instructions.pdf">such as the modality effect</a>, but see <a href="http://dx.doi.org/10.1016/j.learninstruc.2007.09.010">this refutation</a> and this <a href="http://cat.inist.fr/?aModele=afficheN&amp;cpsidt=5135499">other example of a reverse effect</a>).
