I am the course leader for an undergraduate course.
We have two quizzes each semester:
one around the middle of the semester, and one at the end.

For the first quiz,
students were allowed to bring a one-page "cheat sheet"
which could be either handwritten or printed.

Our original intention for the "cheat sheet"
was to encourage students to process the course material
and to summarize it for their own learning.
Unfortunately, I noticed that some of the students
had instead merely printed the lecture slides in really small font.
Instead of actively working through the material,
trying to understand it, select what was important, and write it down,
these students took the easy way out
by copy-and-pasting everything onto their "cheat sheet".

As I began planning for the second quiz,
I decided that students would gain more
from the process of preparing their "cheat sheets"
if they were forced to handwrite their "cheat sheet".
There seems to be some research that backs this up,
for example, this [article](https://www.npr.org/2016/04/17/474525392/attention-students-put-your-laptops-away) says:

> In [the study published in Psychological Science](http://pss.sagepub.com/content/25/6/1159.full?keytype=ref&siteid=sppss&ijkey=CjRAwmrlURGNw), Pam A. Mueller of Princeton University and Daniel M. Oppenheimer of the University of California, Los Angeles sought to test how note-taking by hand or by computer affects learning.
>
> "When people type their notes, they have this tendency to try to take verbatim notes and write down as much of the lecture as they can," Mueller tells NPR's Rachel Martin. "The students who were taking longhand notes in our studies were forced to be more selective — because you can't write as fast as you can type. And that extra processing of the material that they were doing benefited them."

Today, 10 days before the date of the quiz,
I made an announcement in class that for the second quiz,
only handwritten "cheat sheets" are allowed.
One of the students was extremely upset about this policy change.
He felt that:

 1. Making such a change 10 days before the quiz/exam
    is unfair and unprofessional
 2. He had already spent hours preparing his digital "cheat sheet",
    so changing the policy penalizes students like him
    who prepared for their quizzes early.

The student was so annoyed that
he sent an e-mail to the department general office
to complain about this policy change.
I was quite surprised that the student feels so upset,
and I feel that the student is making a mountain out of a molehill.
However, this is my perspective as a course leader,
so I wanted to ask for an impartial and unbiased opinion.

**Questions:**

 1. Am I being unreasonable/unprofessional
by changing the requirements for the quiz "cheat sheet" 10 days in advance?
 2. Is the student overreacting?
 3. Or are both of us in the wrong?

### Response to comments

> If the exam was in the middle of the semester,
> why didn't you bring up the change earlier?

This is a fair question.

The reason why I didn't think about this earlier
is because I was busy with research,
and I only work on what I need to do for the course in the next 1-2 weeks.
This incident has shown me that
there are teaching-related problems that I could avoid in the future
if I were to plan ahead work with a longer time horizon.
However, because I am an assistant professor who is not yet tenured,
to be brutally honest, teaching is not my highest priority.

Although it would be **ideal**
to announce the "cheat sheet" policy 6 weeks in advance,
I feel that announcing the policy 10 days in advance
gives the students enough time to prepare.
I do feel that if I only gave the students 1-2 days of notice,
that would be unfair because I am giving them very short notice.
