    Detailed Course Calendar

    Each paper appears in the calendar below on the day when it will be covered in lecture. Students will find they get the most out of lecture by far when they read papers before they are covered, and are strongly encouraged to do so. Papers marked Pre-Reading: must be read before the day on which they appear in the calendar.

    N.B. that all assigned readings (including those presented by students at the end of the course) are examinable.

  • Z25/4C38 Presentations Guidelines

    Groups

    Your coursework assignment will be a group exercise to prepare and deliver a presentation as timetable above

    All groups are listed here

    Presentation schedule

    The presentations will all take place in a 1 hour lecture slot of Z25/4C38 during the last week of this half-term (06 Feb 2005 - 10 Feb 2006, inclusive). You will have 30mins for your presentation and then 20 minutes for questions from students and staff. So please show be prompt in getting to the lecture room.

    The paper allocation for each group and the schedule for presentations is given above.

    Submission of presentations material

    A single electronic version of your slides (PDF or gzip'd PostScript) should be sent as an email attachment no later than:

         10am on Monday 6th February 2006

    to all the lecturers:

         S.Hailes@cs.ucl.ac.uk           C dot Mascolo at cs dot ucl dot ac dot uk

    What you send us is what we expect you to use during your presentation timeslot.

    Presentation format

    You can use OHP slides and/or laptop presentation with any other appropriate materials or aids.

    All group members should take a turn to speak, and should speak for about the same amount of time.

    Your presentation should include:

    1. a summary of the work/experiments in the paper
    2. the main conclusions drawn and why the work is important
    3. a critical appraisal of the work
    4. a summary and appraisal of some relevant/similar work in the area

    Assessment

    At least 2 members of staff will be present for your presentations. You will be assesed on [% of marks]:

    1. presentation structure and delivery [10%]
    2. a summary of the work in the paper and the main conclusions (a and b) [10%]
    3. a critical appraisal of work in the paper (c) [15%]
    4. a summary and appriasal of some relevant/similar work (d) [15%]
    5. responses to questions [10%]
    6. a short individual report (3 pages of A4 maximum, plus references) discussing the main issues with respect to future development and application of the particular technology/system you have presented. This should be a personal viewpoint backed-up by references to literature in support of the statements in your discussion. [40%]

    The marksheet that the assessors will be using for the presentations can be found here.

    Note that:

    The submission date for the individual report will be:

         Friday 17 February 2006

    You will be required to submit the individual report electronically as well as on paper and you will be sent further instructions by email on how/when this should be done.
