Before
the test started, a student asked me whether or not he could use the
calculator in his cell phone. I said: "No." The students were reminded
more than once to bring their calculator. I didn’t change my decision even
after I was told that there was no signal in the classroom. I just wanted to be
on the “safe side,” since I am no tech savage. (The student then went out to
get a calculator, I think.)
Then, I noticed six people sat next to each other. I knew they were
"friends." So, I asked the whole class to spread out, since there were many seats. No one moved. At that point, I asked the male student in the middle of the six to move, and he did. (I thanked him after the exam was over.)
Toward the end of the exam, a female student tried to use her calculator, and
then “indicated” the battery was low. She "borrowed" the calculator
from a student a seat over, and used it. I walked over to "exam" the
calculator (but really had no idea how to “exam” it. She realized I was not happy, and came to talk to me after the class was over. She asked me not to
"punish" the other student. I looked over their tests later, and didn't found there was any "similarity" in terms of the calculated result.
