AQA-7552-2-DESIGN AND TECHNOLOGY FINAL MARK SCHEME PAPER 2-DESIGNING AND MAKING PRINCIPLES-ALEVEL- JUN 2024. 01 Figures 1 and 2 show two chairs. Analyse and evaluate the suitability of each of the two chairs shown for large-scale production. Marks Description 9–12 marks Full use of the information concerning the chairs has been made to form justified analytical and evaluative statements. Detailed technical knowledge and understanding beyond the information provided is given and related to the suitability for large-scale production. There may be some minor irrelevant comments or lack of clarity in some comments but this will not detract from the overall quality of the response. 5–8 marks Most of the information concerning the chairs has been utilised to form analytical statements. Some technical detail beyond the information provided is given with some reference to the suitability for large scale-production. At the lower end of the mark band there may be limited expansion on some of the information given. The majority of comments will be relevant. 1–4 marks Basic use of the information has been made to compare the chairs shown with limited expansion of the information to show further knowledge and understanding. At the lower end of the mark band comments will be restricted to comparing information given with no further detail. 0 marks No response or nothing worthy of credit. Indicative content Figure 1 • Production methods require large capital investment suitable for large scale production only. • The chair is constructed from sub-assemblies ideal for assembly line production and also for customer assembly after purchase. • The use of colour pigments within injection moulding increases flexibility in large scale production. • The use of a single-piece seat and back reduces the number of components used making assembly quicker and reducing errors in assembly. • Use of temporary joining methods make the chair ideal for flatpacked furniture to reduce transport costs (manufacturers can transport more at one time). 12 marks AO31a and AO31b 000005 Page 5 of 22 DESIGN AND TECHNOLOGY MARK SCHEME – A-LEVEL DESIGN AND TECHNOLOGY: PRODUCT DESIGN – 7552/2 – JUNE 2024 6 • The use of self-finishing PP for the seat reduces risk of chipping and QC issues during production. • The plastic seat can be easily stacked during production and transport. • Powder coating can be performed on the production line. • Eames chair may require warehousing for parts/JIT production as the low carbon steel parts, beech legs and PP chair are unlikely to all be manufactured on the same site. Figure 2 • The use of adhesives make assembly longer and increases storage costs after production due to the physical size of the chair. • The application of paint increases the labour costs, time and increases the need for QC checks on quality of finish. • The use of wastage techniques to create the seat increase material costs and reduces the sustainability of the product. • The use of multiple joints may require complex clamping jigs during assembly. This list is not exhaustive. Accept any other valid responses.

MARK SCHEME – A-LEVEL DESIGN AND TECHNOLOGY: PRODUCT DESIGN – 7552/2 – JUNE 2024



Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant
questions, by a panel of subject teachers. This mark scheme includes any amendments made at the
standardisation events which all associates participate in and is the scheme which was used by them in
this examination. The standardisation process ensures that the mark scheme covers the students’
responses to questions and that every associate understands and applies it in the same correct way.
As preparation for standardisation each associate analyses a number of students’ scripts. Alternative
answers not already covered by the mark scheme are discussed and legislated for. If, after the
standardisation process, associates encounter unusual answers which have not been raised they are
required to refer these to the Lead Examiner.

It must be stressed that a mark scheme is a working document, in many cases further developed and




Y
expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark




G
schemes on the basis of one year’s document should be avoided; whilst the guiding principles of
assessment remain constant, details will change, depending on the content of a particular examination




LO
paper.

No student should be disadvantaged on the basis of their gender identity and/or how they refer to the
gender identity of others in their exam responses.




O
A consistent use of ‘they/them’ as a singular and pronouns beyond ‘she/her’ or ‘he/him’ will be credited in



N
exam responses in line with existing mark scheme criteria.

MARK SCHEME – A-LEVEL DESIGN AND TECHNOLOGY: PRODUCT DESIGN – 7552/2 – JUNE 2024



Level of response marking instructions
Level of response mark schemes are broken down into levels, each of which has a descriptor. The
descriptor for the level shows the average performance for the level. There are marks in each level.

Before you apply the mark scheme to a student’s answer read through the answer and annotate it (as
instructed) to show the qualities that are being looked for. You can then apply the mark scheme.

Step 1 Determine a level




Y
Start at the lowest level of the mark scheme and use it as a ladder to see whether the answer meets the
descriptor for that level. The descriptor for the level indicates the different qualities that might be seen in




G
the student’s answer for that level. If it meets the lowest level then go to the next one and decide if it
meets this level, and so on, until you have a match between the level descriptor and the answer. With




LO
practice and familiarity you will find that for better answers you will be able to quickly skip through the
lower levels of the mark scheme.




O
When assigning a level you should look at the overall quality of the answer and not look to pick holes in
small and specific parts of the answer where the student has not performed quite as well as the rest. If




N
the answer covers different aspects of different levels of the mark scheme you should use a best fit
approach for defining the level and then use the variability of the response to help decide the mark within
H
the level, ie if the response is predominantly level 3 with a small amount of level 4 material it would be
placed in level 3 but be awarded a mark near the top of the level because of the level 4 content.
C
Step 2 Determine a mark
TE

Once you have assigned a level you need to decide on the mark. The descriptors on how to allocate
marks can help with this. The exemplar materials used during standardisation will help. There will be an
D



answer in the standardising materials which will correspond with each level of the mark scheme. This
answer will have been awarded a mark by the Lead Examiner. You can compare the student’s answer
N




with the example to determine if it is the same standard, better or worse than the example. You can then
use this to allocate a mark for the answer based on the Lead Examiner’s mark on the example.
A




You may well need to read back through the answer as you apply the mark scheme to clarify points and
N




assure yourself that the level and the mark are appropriate.
IG




Indicative content in the mark scheme is provided as a guide for examiners. It is not intended to be
exhaustive and you must credit other valid points. Students do not have to cover all of the points
mentioned in the Indicative content to reach the highest level of the mark scheme.
ES




An answer which contains nothing of relevance to the question must be awarded no marks.
D
