This is the time of year when we craft exam questions and grading grids in anticipation of exams.
Aside from Teaching Law by Design (a fabulous resource that I recommend for all new teachers as a great continuing resource for even those grizzled from years in the trenches), I have used few formal resources to guide my exam writing and grading process. Fortunately, I work with creative, collaborative and generous colleagues who all shared lots of samples and tips when I first started writing exams. Before committing myself to my Corporations exam this year, I decided to see what is out there to guide exam construction and grading. Finding little that was useful on SSRN or Westlaw, I turned to a broader search, which brought me to a general test instruction guideline produced by Indiana University, aptly titled: How to Write Better Tests. It had the following information regarding essay exams that serve as a useful reminder about why we are so meticulous in constructing our grading rubrics and creating grading schemes that, to the greatest extent possible, reduce our individual biases.
Consider the limitations of the limitations of essay questions:
1. Because of the time required to answer each question, essay items sample less of the content.
2. They require a long time to read and score.
3. They are difficult to score objectively and reliably. Research shows that a number of factors can bias the scoring:
A) Different scores may be assigned by different readers or by the same reader at different times
B) A context effect may operate; an essay preceded by a top quality essay receives lower marks than when preceded by a poor quality essay.
C) The higher the essay is in the stack of papers, the higher the score assigned.
D) Papers that have strong answers to items appearing early in the test and weaker answers later will fare better than papers with the weaker answers appearing first.
To combat these common issues the guidelines recommend:
- anonymous grading (check)
- grading all responses to question 1 before moving on to question 2, and so on (check)
- reorganizing the order of exams between questions (check)
- deciding in advance how to handle ambiguous issues (check, thanks to my grading rubric)
- be on the alert for bluffing (CHECK!)
If anyone has found a particularly useful resource regarding exam construction and grading, please share in the comments. I am sure everyone would benefit.
Happy Thanksgiving BLPB readers!
