John,
The reason I believe that jammers are acceptable in classrooms is
that classrooms should be dedicated to teaching and learning. Now
consider the implementation of your idea, and how it would/might affect
the learning environment.
1. Who is going to make the rack?
2. Why would a student put his cell phone there? And if he doesn't, do
we go back into punishment mode? If so, why bother with the rack?
3. What about phone stealing?
4. What if the phones in the rack are on and they ring during class?
5. What about students who leave their phones behind?
None of these will improve the learning environment. All of them take
attention away from teaching and learning. Your idea just places more
attention on the cell phones. And the fact that they are getting so
much attention is the problem in the first place. I think jammers are
appropriate in the classroom.
Obviously, as with some of your students, you are unable to learn about some
subjects. What you *think* about jammers is wrong, as their use is illegal.
You get a FAIL.
Thanks for the grade. If the need for cell phones is so great, why not
allow the teacher a cell phone, the number of which is given to all
students. They can then give this number to their emergency contacts.
Of course, most calls are not related to emergencies.
So, consider this, classrooms are painted with a special paint which
has metallic flakes. This, along with metal window screens, produces a
Faraday cage, and no signals can enter the room? Is this okay? It is
legal. And if it is okay and legal, and it clearly intended to block
cell phone usage, why is jammer illegal?
