I’ve come across several requests for new projects to support a revision of current KS3 schemes of work. My usual response has been don’t start with projects, start with what you want the pupils to learn. But I’m beginning to wonder if it’s possible to start with an existing and somewhat limited project and revitalise it by considering what might be learned if it was extended in various ways. This led me to consider the designing and making of clock faces. Many schools get pupils at KS3 (or even KS4) to design and make clock faces, providing a bought in mechanism to move the hands. My impression is that they use this as an opportunity to explore the aesthetics of particular design movements. So we get Mackintosh or Memphis or Bauhaus derive clock faces. I’m not sure that this is the best use of precious design & technology time. Surely the interesting idea behind such work is that we can devise machines that can record the passage of time. Being able to tell the time has had a large impact on the way we live our lives. Before this was possible sun rise and sun set provided the boundaries on our days with inadequate and often poisonous lighting (oil and kerosene lamps) giving some respite from darkness. So understanding the impact of measuring time on our lives and how this can be achieved would seem to have great potential in a design & technology course that was concerned with both perspective – understanding the interaction of technology and society, and capability – designing and making things that work. So some questions to consider:
- Why might we need clocks?
- What do various people use clocks for?
- Who wins and who loses when people have clocks?
- What sorts of clocks are there?
- When and where were different sorts of clocks invented?
- How do they work?
The history of clocks goes back a long time, starting with sundials and water clocks. The use of pendulums and springs then allow the invention of mechanical clocks which include some very delicate and accurate components moving on jewelled bearings. Such clocks needed winding up using a hand turned key but this function was overtaken by the electric motor. And then we reach the quartz clock that uses an electronic oscillator regulated by a quartz crystal to keep time. Most modern clocks (and watches) now operate this way.
It seems to me that there has got to be some good design & technology in a consideration of clocks that goes way beyond what their faces look like. It will be no mean feat to derive a unit of work that looks at the insides as opposed to the out sides of timepieces but I think the rewards in terms of learning would be great. All the BIG ideas will be represented to some extent – materials, manufacture, functionality, design and critique. And such a unit of work could embrace making without designing, designing without making, design and making and considering consequences. I expect other areas of the curriculum would be interested – mathematics, science and history. So as we prepare for the new GCSE and start to revise our KS3/4 offerings consider what we might teach if we seriously revamped ‘the clock face’ project.
As always comments welcome.
