Maths Problems Classes - Demonstrator Guidelines
The problems classes associated with mathematics modules delivered by Physics:
are co-ordinated by the module instructors, normally assisted by a PDRA.
- Problem sheets will be distributed a week in advance of the class and at that
time markers will get a set of solutions and a mark scheme. Please contact the
appropriate module leader if you have any
queries about the solutions or scheme.
- Students have to hand solutions in before the problems class.
The names of those submitting work will be recorded, the
scripts divided and circulated without delay to markers who must
return the marked scripts at least one hour before the class starts. [Markers will
be advised of the precise deadlines which vary from year to year depending on the timetable.]
- Students are encouraged to work together as part of the learning process and
what you get may be a "collective" solution. It is made clear to the students that we want
their version of the solutions, so please bring an evidence of identical
solutions to the attention of the class co-ordinator.
- We have attempted to indicate on the model solution the steps and stages that
gain marks. Of course, students will not always solve the problem in an
identical way and if so try to follow the spirit of the scheme avoiding simply
awarding zero or maximum for serious attempts to the questions. If you are in
doubt discuss it with the appropriate module leader. Remember that students may
cross-compare marks, and query apparent inconsistencies. Indicate on the script
the point at which the solution went astray and follow it up in the class.
- During the class help the students to understand where they went wrong and to
appreciate what they needed to do to make progress. Try to be as clear as
possible and as helpful as possible but also avoid getting committed to one or
two people for the whole of the class - suggest ways in which they make progress
themselves while you move on.
- Once the feedback from the problem paper has been completed then students are
expected to work on the new topic which they started in the preceeding lecture. Be
proactive and if they say they have no problems ask them what they are doing and
get them to explain to you what they comprehend. If they are stuck establish
where they are held up and make a suggestion of how they might best progress -
don't simply solve the problem for them completely.
- If you find a student you feel is struggling and having difficulty coping let
class co-ordinator have their name.
