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.

CanningBacteria are deprived of air [1] so they cannot multiply and cause decay or poisoning [1];Bacteria are destroyed / killed if the food is heated to a very high temperature [1] so they cannot multiply and cause decay or poisoning[1];Bacteria cannot multiply [1] in high acid, salt or sugar liquids [1] and cause decay or poisoning[1]. Micro organisms require an optimum pH [1] to sufficiently reproduce / multiply to cause food poisoning [1].

Too acidic. Too salty / sugary. No air.

FreezingBacteria cannot multiply [1] and cause decay or poisoning because the freezing temperature -18/ 32C [1] makes them dormant / inactive [1].

Too cold.

Vacuum PackingBacteria are deprived of air [1] so they cannot multiply [1] and cause decay or poisoning[1].

Parts inside the chicken that are still frozen when in the oven will be slower to reach the maximum cooking temperature [1] and could allow bacteria to multiply [1].Cooking: Use a temperature probe [1] to check that the internal temperature is correct for ensuring complete cooking to destroy bacteria [1].Check oven tempHot holding: Monitor the temperature [1] that the chickens are displayed at to make sure no bacteria develop if the temperature falls [1]. Check temperature every 20 minutes [2].

(a) For a product which is not savoury, mark communication not interesting or materials.For a product which is not a single portion, mark communication and materials not interesting.For a product which does not have an interesting pastry case, mark communication and materials not interesting.For a product that does not have a good source of protein and fibre, mark communication and interesting not materials.

Note: If design 2 is only slightly different award up to half marks.

(i) InterestingAn interesting single portion product based on a flan, tartlet, pie or pastie made from filo, cheese or flavoured pastry. The shape may be an alternative to a round flan/tartlet or a semi-circular pastie. The pastry contains additional ingredients e.g. olive oil, olives, sun dried tomatoes or cheese. A pastry case may have surface decoration. The filling is an exciting selection of food materials showing imagination. The pastry may be named as flaky, puff, filo, choux, cheese. It may contain herbs, seasonings, spices, garlic, sundried tomatoes, and olive oil for flavour.

A variation of two of the above features which attempt to create an interesting, savoury, pastry product.

A product based on an existing type with basic S.C.Pastry and a limited suggestion for an interesting filling.
