                       Advice to teachers / students:
• Choose the two Optional areas of study as early as possible
  and focus on these in parallel with the Core options.
• Focus time and energy on doing your chosen questions as
  well as you can. Attempt the required number of questions and
  the required number of parts within each question.
         (OL - Ensure you answer two Options).
• A possible approach may be to answer the option questions
  before the long core questions.
•Answer in point form and be as specific as possible.
• Where possible, annotate sketches – practice sketching.
• Calculations: Show formula and calculation as well as
  final answer and remember to convert units where appropriate
• Familiarise yourself with marking schemes and sample answers to
  previous examinations (www.examinations.ie)

 Thematic Brief 2010 (H L)
Entertainment events are enhanced by the settings in which they
occur. Of particular importance is the performance area which
enriches the audience experience through the creative use of
structures and of factors such as movement, light and sound. With the
evolution of personalised technology, opportunities now arise for
individual members of the audience to interact with, and create an
effect on, the performance area.

Within the context of contemporary design and with a focus on
enhancing the audience experience, design and make a working model
of a dynamic performance area for an event of your choice. Individual
audience members should have the opportunity to enhance their
experience through interacting with the performance area.
This model should incorporate electronic and / or mechanical systems
and should also be well presented.
Note: The maximum dimension of the artefact you present for
assessment should not exceed 500mm

    Thematic Brief 2010 (OL)
Road safety is an important issue for all road users. The importance
of seat belts, helmets, high visibility clothing and road signage is often
communicated through radio, television, poster campaigns and other
media. However, some road users have not yet understood the
importance of the road safety message.
Dioramas are colourful animated displays which often incorporate
structures, mechanisms and electronics. These dynamic visual
displays are used to increase the impact of important messages.

Design and make an animated diorama to communicate an aspect of
road safety which you consider to be important. The diorama should
be attractive, incorporate a mechanical and / or electronic system and
should be well presented.

Note: The maximum dimension of the artefact you present for
assessment must not exceed 500 mm.

  Feedback - General
• Some excellent folios and artefacts submitted
• Majority of candidates submitted an artefact and folio
  OL folios should follow the format provided with
  coursework briefs

• If sitting an Ordinary Level paper then it is highly recommended that
  an ordinary level project is submitted.

• Attention to ‘completeness’ is vital;

    Important to complete each subsection in folio
    Finish and presentation of artefact is important
    Keep a photographic record of important processes as they are complete
    Drawings for manufacture should be clear and detailed.

• Attention to the subsystem component – (electronics and/or mechanisms)
  throughout folio and artefact is significant
 Design folio - HL

  Important to note that the HL
design folio provides the essential
context in which the coursework is
             examined.



   Important to maintain high
standard as folio provides 50% of
       coursework marks
       Folio overall comments
Analysis: Research detail excellent in many cases. Weaker candidates
           provided general research on tools/equipment etc. All research
           must focus on thematic brief provided. Specification of chosen
           parameters still not included in some folios.
Environmental impact: Well answered. Candidates could also consider
         energies used in tools, equipment, circuits & soldering requirements

Research, investigation and specification of brief: It is important for
candidates to state clearly as a final brief, what exactly they are going to do.

Design ideas and selection of solution: Quality of sketching/drawing varied
greatly. Optimum solution should be clearly identified and effectively justified

Testing, evaluation and critical reflection: Further scope for development i.e.
Artefact evaluated through:
     • initial stated brief & objectives,
     • projected manufacturing objectives,
     • possible modifications to improve/develop the product.
                 Artefact

          Higher Level
Significant rise in overall grades for 2010 due to
candidate performance in the production of the
artefact
          Average mark for HL artefact: 80.1
    Artefact - Higher Level
Most common solutions:
    • Concert stage, audience control of lights, sound & movement
    • Judging control of auditioning competitions
    • Model of quiz shows
    • Sports arenas with audience control
    • Fashion shows with participant control of lights etc.
    • Boxing rings with voting interactivity
Excellent range of solutions were presented with very effective and innovative
designs attempted.

Use of new materials, new equipment such as CNC routers, PIC control are
starting to help improve the quality and working of products.
Quality and finish of presented artefacts is improving, however, issues such as:
    •   Edge finishing of parts
    •   Use of adhesive
    •   Polishing                           Still need particular
    •   Loose wiring                               attention
    •   Assembly techniques
   Artefact

Ordinary Level
  Artefact - OL

Most Common solutions:

             • Rotating road signs,

            • Warning messages,

            • Flashing LED highlighting hazards,



    80% of OL candidates submitted a folder for
                   assessment
 Cousework Summary


• Complete all sections of folio

• Identify research parameters and artefact
       specifications

• The circuit and mechanism is an integral part of project
  from start to finish

• A high level of finish is important

• Remember to Test and Evaluate the finished artefact
