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.

  1. 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.
     
  2. 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.]
     
  3. 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.
     
  4. 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.
     
  5. 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 returning later to check up complete sets of solutions are placed in the School Library.
     
  6. 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.
     
  7. If you find a student you feel is struggling and having difficulty coping let class co-ordinator have their name.
