At Blackheath High School GDST, our ‘through school’ structure provides a unique longitudinal view of a designer’s journey. I am in the fortunate position to see how the foundations laid in the Junior school manifest in our A-Level students, allowing me to treat the curriculum as a living, breathing feedback loop. Recently, we identified a need for more precise measuring and joining techniques at the lower Key Stages. My solution was to introduce working from technical drawings: a move I usually avoid for fear of ‘cookie-cutter’ outcomes.
However, this is where things got interesting. Inspired by the sleek, minimalist aesthetic of Playforever toys, I challenged the students to build a motorised vehicle using a TTS Motorised Car Class kit. After I modelled a base template in Tinkercad, the students were tasked with designing an outer shell that wasn’t just decorative, but functional.
The process didn’t stop at the screen. Once the Tinkercad designs were complete, the girls moved directly into building with the wooden chassis, navigating the gap between what looks right on screen and what actually works on the bench. They had to create access points for batteries and switches, ensure clearance for moving mechanisms, and calculate mechanical tolerances so connections were secure but not seized. Far from being restricted, the girls found that having a fixed technical ‘anchor’ allowed their creative iterations to be more daring and purposeful.
In British industry, specifically within the high-performance engineering hubs of ‘Motorsport Valley’, the finished product is merely the final 5% of the story. In Formula 1, a car is never truly finished; it is a rolling prototype in a constant state of flux. If we prioritise the polished end-product over the rigorous, failed iterations that preceded it, we are fundamentally misrepresenting how world-class engineering works.
Lessons from the Paddock: Precision over Polishing
In our car project, I wasn’t concerned if the final design was a perfectly painted toy. The real work happened when a student realised her Tinkercad shell didn’t account for the switch’s swing-radius or the space required for the motor to spin freely.
By asking the pupils to work within specific margins in their digital designs, and then testing those margins against the physical wooden chassis, we moved away from a culture of “near enough is good enough.” We moved toward the precision of the British automotive sector. When the goal is solely a beautiful finished product for a display board, students become afraid to take the very risks (the bold cuts or the complex joints) that lead to technical breakthroughs.
Bridging the Industry Gap
If we want D&T to reflect how design actually works in industry, we need to move away from a craft-only mentality and toward Industrial Design. This means:
• Embracing Constraints: Using technical drawings not to stifle creativity, but to provide the constraints that make the students actually think.
• Prioritizing Systems Thinking: Understanding how a shell interacts with a chassis, a battery, and a user, just as a racing team has to account for every millimetre.
• Valuing the ‘Failed’ Iteration: Grading the journey of the prototype. A student who’s reworked her design three times because the switch won’t fit has learned far more than one who followed instructions to a tidy finish.
A Call for Boldness
What I found most energising about planning this project was that there was no fixed route through it, and it felt much more like genuine Design Thinking than a traditional scheme of work. And that, I think, is where the real value of Design and Technology lies: in its ability to teach students how to navigate uncertainty. We shouldn’t just be teaching them to follow a set of instructions to reach a predetermined destination; we should be equipping them with the confidence to question, test, and refine their own ideas. If we want a D&T curriculum that reflects the world-leading innovation of British industry, we must give our students the permission to take risks and, crucially, the permission to fail.
At Blackheath High, we are finding that when you give a student a technical drawing and a difficult constraint, you don’t get twenty identical cars. You get twenty unique designers who understand that in the real world, the “magic” happens in the margins. And who knows? If we keep encouraging this level of divergent thinking, I might finally get my wish and find myself commuting to work in a high-performance, aerodynamic baguette car by 2035. At the very least, the morning traffic would smell a lot better.
