MARKING SCHEMES
SUMMER 2007
DESIGN AND TECHNOLOGY
INTRODUCTION
The marking schemes which follow were those used by the WJEC for the 2007 examination in GCSE Design and Technology. They were finalised after detailed discussion at examiners' conferences by all the examiners involved in the assessment. The conferences were held shortly after the papers were taken so that reference could be made to the full range of candidates' responses, with photocopied scripts forming the basis of discussion. The aim of the conferences was to ensure that the marking schemes were interpreted and applied in the same way by all examiners.
It is hoped that this information will be of assistance to centres but it is recognised at the same time that, without the benefit of participation in the examiners' conferences, teachers may have different views on certain matters of detail or interpretation.
The WJEC regrets that it cannot enter into any discussion or correspondence about these marking schemes.

You could use pro-desktop or any similar software to try out different finishes 2 marks.
Designs could be emailed to others for evaluating 2 marks.
Look for activity or verb E.g. Consider, test, research, model, look at, add, experiment etc.
AND the qualification.
Activity (1 mark) qualification or explanation (second mark).
(c) For a product of your choice, describe two benefits of using CAM (aided manufacturing) to make the product. 3 x [1]
Award a mark for the product as answers must be related to the product.
For a clock 1 mark.

CAM can be more accurate at mass producing clocks than by hand 1 mark.
Example (1 mark) qualification (second mark).
Faster no marks.
