2. Identify and list all dimensions of divergence (equivalence classes) for the procedure. Make sure the generality deals with all of them. 

3. Assess the difficulty level of the procedure for the target learners (on, say, a scale of 1-5). 

4. Create an instance pool that contains x items per dimension of divergence, where x is about twice the difficulty level. 

5. Create a test, using at least one item randomly selected from each dimension of divergence. If the procedure is a difficult one, increase the number of items per dimension.* 

6 Create practice items, using at least two items randomly selected from each dimension of divergence. If the procedure is a difficult one, increase the number of items per dimension.* 

7. Create examples, using at least one item randomly selected from each dimension of divergence. If the procedure is a difficult one, increase the number of items per dimension.* Include appropriate power components, depending on the difficulty level of the procedure. 

8. Create the feedback for the practice items so as to be virtually identical to the enhanced examples. 

9. Think about motivational needs and media selection, and modify the instruction as appropriate to each. (This should be done throughout the process, not just after all else is done. 

* Note: In general, the number of examples and test items should be about the same, and there should be at least twice as many practice items as examples.
