Design instruction
 
 
        The outcome of brainstorming is a long list of ideas that range in quality from very bad to very good.  You must eliminate the worst ideas and then begin ordering, detailing, and refining the ideas that are good.  This is done by performing concept and task analyses on the content.  Regardless of the nature of the content, such analyses bring to bear principles of learning to assemble a plan for an effective lesson. This includes preliminary choices about instructional methodologies and factors.

                It cannot be emphasized enough that good instructional development incorporates evaluation throughout the process, not just at the end.  This is reflected in the model by incorporating explicit evaluation and revision activities as part of several steps. After the design step, evaluation includes review and discussion by the content experts, instructional designers, and clients. Revision may require reassessment of goals, collecting more resources, learning more about the content. generating more ideas, correcting task analyses, changing the methodology, and so on.  After revision the evaluation should be repeated.  Evaluation and revision form a cycle which progresses until all concerned parties are agreed that the quality is sufficient to progress to the next step.
