Assignments and case studies: brief, rubric and marking

Putting learners in a situation proves they can do the job. How to write the brief and rubric, and use automatic marking without losing control.

A quiz tells you that Chloe knows the client follow-up method. It does not tell you what she will write to an unhappy client, on a Tuesday morning, when the supplier is late. The assignment shows you that. That is where you see whether the person can do it, and not only whether they can repeat it.

Why put the learner in a situation

A case study describes a real or plausible situation, sometimes with incomplete information, and asks for a decision. The Harvard Business School case method rests on this principle: the reader takes the role of the manager and must decide, then defend the choice in front of others.

Why does this work? Because working life does not look like a list of questions. It looks like an angry client, a tight budget, missing data. Practising in a risk-free setting prepares you for those moments.

Writing a brief that is understood first time

Most failed assignments come from a vague brief. A clear brief answers five questions, in this order.

QuestionExample
What is the situation?A client reports two late deliveries
What is your role?You are the customer service manager
What must you produce?A reply email of 10 lines at most
With what material?The client file and the delivery schedule
Against which criteria?See the rubric below

Always finish with the last point: the learner must know the criteria before writing, not after. An exercise whose rules stay hidden is a lottery.

Building a rubric of three to five criteria

A rubric, also called a marking grid, lists the aspects to judge, describes what each one means, and provides levels of mastery. The Eberly Center at Carnegie Mellon University describes it this way: criteria, descriptors and performance levels.

Do not turn it into a monster. Three to five criteria are enough. For the follow-up email:

CriterionInsufficientAchievedVery good
ToneCurt or aggressivePolite and neutralPolite and reassuring
SolutionNo proposalA vague solutionA dated, precise solution
ClarityHard to followUnderstandableDirectly usable

The same resource centre notes that these rubrics also help the learner, who understands what is expected and tracks their progress, and the trainer, who gains consistency from one script to the next.

What automatic marking brings

Marking forty case studies by hand takes whole evenings, and the feedback arrives when the learner has already moved on. With automatic marking, they receive a first piece of feedback immediately, while the subject is still fresh. You gain time for what matters: reading the difficult cases and talking with people who are struggling.

In Kognisia, case studies with automatic marking are added to assignments and quizzes in a single learning path. You then see in progress tracking who has submitted what, and where the group hesitates.

The limits: keep a human review

Automatic marking is not a panel. It can miss an original but valid answer, or misjudge a nuance. It does not know the particular context of a learner, for example an employee who works in an unusual sector.

My view: never leave to the machine alone a decision that matters for the validation of a path or a certificate. Keep three habits:

  • review a sample of the marked scripts, each session;
  • review all scripts that are contested or close to the threshold;
  • adjust the rubric when you see a repeated error.

The assignment goes very well with a well-built quiz: the quiz fixes the basics, the assignment checks they are put to use.

Frequently asked questions

What is the difference between an assignment and a case study?

An assignment asks for a piece of work on a given subject, such as a summary or an action plan. A case study places the learner in a specific situation with materials, and asks them to decide and justify.

How long should I allow for a case study?

Between 20 and 45 minutes for most short learning paths. Beyond that, split the case into two stages with feedback between them.

Should the rubric be given to learners?

Yes, before the work. It serves them as a guide and spares you discussions about the mark afterwards.

Does automatic marking replace the trainer?

No. It gives quick feedback and lightens the load, but human review remains necessary for borderline cases and for decisions that commit the validation.

In summary

A good assignment puts the learner in a situation, announces its criteria and gives quick feedback. Automatic marking saves time, provided you keep human review for the cases that matter. Next step: choose a real situation from your trade and write its rubric in three criteria.
