Assembly: marginal gains and resolutions

CRH Marginal Gains Assembly

In this week’s assembly, I’ve been talking about marginal gains and resolutions. I started with the picture above: many students had a go at guessing what these objects were! The answer is that these are ‘bum warmers’, used to warm the muscles of Olympic cyclists before a race. The extra warmth means the cyclists can start one hundredth of a second faster than their opponents.

These curious devices are one example of the British cycling team’s approach to the “aggregation of marginal gains.” This approach means making tiny improvements in lots of different areas, adding up to a big overall effect. Other examples include the the cyclists always taking their own pillows and bedding with them when they travel, to reduce the chance of picking up an infection which might interfere with their training. The team tweak every aspect of the bikes, the cyclists’ equipment and clothing, their diet, sleep, schedule and training regime to try and eke out an extra 1% of performance.

It’s an approach which seems to have worked. In the four Olympic Games between 1992 and 2004, the cycling team managed to win eight medals; following the adoption of the marginal gains approach, the team won 41 medals across Beijing 2008, London 2012 and Rio 2016.

Marginal gains in school

I want us all to think about what marginal gains we could make in school. What small changes could we make to our approach which, sustained and added up over time, could result in a big improvement?

One change could be in making the most of the time we have. Spending five minutes of a lesson off task – daydreaming, chatting to a friend, looking out of the window – doesn’t seem like too much of a problem. But adding it up over a year can result in a lot of lost time…

  • We have five lessons every day for 190 school days in a year
  • That’s 5 x 190 = 950 lessons per year
  • Five minutes wasted in every lesson is 5 x 950 = 4,750 minutes
  • 4,750 minutes is just over 79 hours
  • That’s over THREE WHOLE DAYS of learning lost per year, just from five minutes in each lesson (three days, seven hours and ten minutes, for precision fans).

Ensuring we attend every lesson punctually, and staying focused when we are there, is a marginal gain we can all make that could add up to a big overall effect over time.

Making a resolution

New Year’s resolutions are notoriously hard to keep. This can be because they are too ambitious. But the advantage of resolving to make a marginal gain is that it involves a small change – or perhaps a number of them! Making resolutions to stay focused, to ensure that all equipment for school is prepared the night before, to avoid distractions, or to be more punctual to every lesson…these are not impossible goals to set ourselves, but added up they could make a significant difference.

What will your New Year’s resolution be?
