Marked only by official IB examiners

If you're an HL student, Paper 3 is the last exam you'll face in your IB Design Technology assessments. In this post, we’ll provide a thorough breakdown of the paper, ensuring you are familiarised with the structure of the exam and know what type of questions to expect. 

 

IB Design Technology Paper 3

 

  • Paper 3 is an HL-only paper.
  • Paper 3 accounts for 20% of your final grade. 
  • Students have 1 hour 30 minutes to complete Paper 3.
  • Students can score up to 40 marks.
  • Paper 3 is made up of structured questions on HL extension material.
  • Students answer all questions.
  • Paper 3 is made up of two sections.
  • Section A focuses is made up of shorter questions. 
  • Section B is an unseen case study question.  
  • A calculator is required for this paper.

 

 

A typical Section A question may look the following way:

 

The authorities in Qinhuangdao, China are prototyping the Transit Elevated Bus (TEB). The TEB runs on rails and has 2.1 m of clearance over the road below. This allows the cars to share the road as shown in Figure 1.

 

The TEB can use the existing roads and transport 1400 passengers at up to 60km/h. 

 

(a) List two ways in which the Chinese user population influenced the TEB design concept. [2]

 

(b) Outline the importance of a multidisciplinary design team for the TEB. [2]

 

(c) Outline the role an ethnographer may play in the design team for the TEB. [2]

 

(d) Explain one benefit of enhanced usability of the TEB and how it would contribute to its success. [4]

 

 

A typical Section B question may look the following way:

 

The Vozz Helmet, see Figure 3, is a revolutionary motorcycle helmet with a hinged shell and no chin strap. It is marketed as a high-quality, comfortable and practical helmet.

 

The Vozz Helmet has a hinge at the top which allows the user to put it on while wearing glasses or with your gloves on. There are clips on each side of the chin piece and these can be clicked together. This removes the need for a chin strap. 

 

The main reason why the Vozz Helmet has been designed in this way is to make it easier and safer to remove the helmet from the wearer in the event of an accident. Figure 4 shows the special release system. The helmet also has a Vozz logo that the paramedic can scan enabling them to get instructions over their phone on removal procedures.

 

Once the paramedics have been able to operate the special release system they can remove the helmet by detaching the front part as shown in Figure 5.

 

(a) Outline why frequent contact with potential users is essential by the design team for the development of the Vozz Helmet. [2]

 

(b) List two promotion strategies that could be used to market the Vozz Helmet to motor cycle riders. [2]

 

(c) List two reasons why interviews would have been utilized as a user research strategy in the development of the Vozz Helmet. [2]

 

(d) The Vozz Helmet has gained acceptance for use in motorcycling and Vozz intends to extend its product range. Explain how the Vozz Helmet could be developed as a product family. [5]

 

(e) Explain the importance of quality management through quality control (QC), statistical process control (SPC) and quality assurance (QA) to ensure that the Vozz Helmet is produced to predetermined quality standards. [9]

 

 

How to succeed in Paper 2?

 

To succeed in IB Design Technology Paper 3, it is essential to understand that this paper is exclusively for Higher Level students and hence focuses solely on the HL topics. These include User-Centred Design (UCD), Sustainability, Innovation and Markets, and Commercial Production. Mastering these four areas is key, as Paper 3 does not test the core topics (although, of course, a foundation in the core is helpful).  

 

Paper 3 consists of two main parts: structured questions and an unseen case study. The structured questions target specific HL concepts. The second section – the case study – presents a new and unfamiliar scenario where you are expected to analyse the situation and apply your HL knowledge to offer well-reasoned responses. Success in this section depends heavily on your ability to think critically and apply concepts in real-time, not just recall information. You should also develop the ability to bring in relevant, real-world examples to support your arguments.

 

To prepare effectively, practising past Paper 3 questions is crucial. This will help you become familiar with the style of both structured and case study-based questions. Make a habit of reviewing mark schemes alongside your practice to understand how to frame answers clearly and logically.
