A. To develop the initial cases we used the following format.

1. To begin, the authors are asked to write down a topic they would like to teach, and one big “take home” message on this topic.
   
   
2. Next, individuals are asked to think of two or three realistic settings or scenarios useful for leading students to explore that topic.  Avoid sci-fi scenarios, or having animals or plants talking.  It's very confusing and not usually appreciated by learners.
   
   
3. Working in pairs, each member explains their topic and possible scenarios, with the intent of convincing the partner of the utility of at least one of the scenarios. 
   
   
4. Next, each individual drafts a brief paragraph or two describing the scenario/situation as though writing to a nonscientist friend. 
   
   
5. In the last step, new partnerships form, and each author reads his or her case aloud with the partner responding by telling what he or she thinks the case is about.

B.  We used the following case review process for further case development: 

1. Without preamble or explanation of any kind, the case author reads the case out loud to a small group of willing listeners whose job is to tell the author what the case is about.
   
   
2. The other members of the group offer suggestions (preferably in the form of questions that the case stimulates for them) as to what the case is about.  The author writes these down.  The author does not respond to the feedback from the listeners. 3.   After all the listeners have had their say, then the author shares what he or she intended the case to be about.  Sometimes there is great congruence between what the listeners think and what the author intended, often there is some incongruity.
   
   
3. When there is much incongruity, it’s time to think about recasting the case, perhaps in a new scenario. 

   Note:  It's best to delay the discussions of teaching strategies, assessment strategies, and the like, until steps 1-3 are complete

 C.  Structuring the Case for Learning

Once the story clearly leads to the intended objectives, it is time to start structuring the case for teaching.

1. Go through the case and decide which terms or phrases are the "hooks" -- those that stimulate questions, learning, etc. Write down for each part of the case the issues that are stimulated by that part of the case. (See the short illustration of this process on the case "Fleaing Louisiana.") This step allows the author to decide if any paragraph has too much or too little content.
   
   

2. Decide where the story should be split up into parts for the students to work on a bit at a time.  Keep the parts short.  They will contain much more learning material than you anticipate.  This is called "splitting up the case" for teaching/learning.  Of course, if you choose to have a case with only one part this step will be unnecessary.
   

3. In addition to the story (the narrative) the case might also have as components:

•      A list of resources - you may wish to supply a starting list of readings, web sites, etc.  You can make this longer or shorter, depending on your goals for student learning.  If you want students to learn to find resources, the list will be shorter, of course. 
  

•      List of learning goals (these may or may not be given to the students).  It is helpful in some circumstances to provide students with a list of the learning objectives you had for the case.  It is important, however, to delay giving this to them until after they have worked on the case for some time.  Otherwise, the learning becomes too teacher-directed and the power of student-centered learning is lost.
  

•      Instructor’s guide - this is important if you are teaching a course with multiple instructors or if you are planning to publish the case.  The instructor’s guide lists the objectives and the main anticipated learning issues.  It may also have information about resources, related learning activities, possible student projects, suggested products students could create related to this case, and the like.
  

•     Visuals, simulations, web sites - these are all possible components of cases that can be an integral part of the case or resources to support learning with the case.
  

D.  What else goes with the case in your course?

You might want to think about the larger picture of which the case is one part.  How will you assess student learning?  What learning activities might you link to the case to enhance learning?  What products or artifacts might students produce as a result of working on this case? 

See the case modules produced by workshop participants in the 2000 LifeLines OnLine, BioQUEST and HHMI workshops for samples of the ways cases are linked to activities and assessed.
