Cheating
There are two kinds of unauthorised
use or access which may give problems: expert hacking,
and casual attempts by students to cheat.
Casual Cheating and Unsubmitted
Exercises
There are some obvious ways in which
students can cheat. For example, they might download
an exercise, so that they have an opportunity to see
the questions, then avoid actually doing the exercise
on screen at that time. They could take as long as they
wish to find the answers, then download the exercise
again, and complete it perfectly.
It is impossible to prevent this type
of behaviour, but hotpotatoes.net does record every
occasion on which an exercise is downloaded by a registered
student, and records the student name and download time.
Whenever a teacher sees a list of exercise results,
they will also see a list of the occasions on which
the exercise was downloaded but not submitted, and this
should allow the teacher to see when students are cheating
in this way. The results are displayed like this:

This shows that Fred Smith scored
99 when he completed the "Too Many Cooks"
exercise on the 30th October, but also that he had previously
downloaded the exercise on 28th and 29th. He did not
complete the exercise on either of these occasions,
but he may have had an opportunity to see the questions.
The hotpotatoes.net system does not
try prevent this kind of behaviour - it simply informs
the teacher knows that it is happening, so that the
teacher can act on it if s/he wants to do so. The existence
of unsubmitted exercises does not prove that a student
has been cheating, or deliberately misusing the system
- for example, a few unsubmitted exercises may simply
indicate that the student is using an unreliable internet
connection. It is for the teacher to decide what response,
if any, is appropriate.
Extra Information - Host Names
and IP Addresses
As well as the score, and an optional
student comment, the results system also stores the
host-name (computer name) and IP address (internet number)
of the computer from which the exercise was submitted.
Those who understand this information may find it useful,
especially for tracking and monitoring students who
are suspected of collaborating unfairly, or cheating.
Expert Hacking
hotpotatoes.net is as website, and
as such, it may be possible for expert users to gain
unauthorised access to it, and to alter the records
and results stored here. We have put in place every
security measure available to us, within the technological
restrictions under which the system works, but we cannot
guarantee that cheating is impossible, or that the system
cannot be "hacked".
It is therefore important to remember
that the results scoring system is not designed for
use in testing for statutory examinations or formal
qualifications. hotpotatoes.net is only as secure as
any other online environment, and is inherently less
secure than a supervised examination room.
If you know of or suspect that some
unauthorised access has been made to your account, or
to any of the information or results stored there, please
let us know urgently. In the UK, unauthorised use of
computer systems is a criminal offence.
