1.
Record an Olympic diving event to whichever medium is convenient
for you e.g. video, dvd, perhaps Youtube
2.
Outline the scoring method to the students  i.e. discard
the highest and lowest scores  add the remaining numbers
together  multiply by the degree of difficulty. This will give
you the score for the dive.
E.g.
if the judges award 8.5, 8, 8.5, 9 & 9.5  discard the 8
& the 9.5  then add 8.5, 8.5 & 9 which gives 26. Next
multiply 26 by how had the dive is. If the Degree of Difficulty
(DD) is 3.4 then you multiply 26 by 3.4 meaning that the final
score for the dive would be 88.4
3.
Play a dive then stop it and write up the judge's scores. Have
the students calculate their scores in pairs with a calculator.
Then continue the video and have the students self confirm their
answers.


4.
Once the students get the hang of this part you can talk a little
about the marking criteria for the dive and see if they can get close
to the judge's initial scores

approach
 height above board
 how good the acrobatics were
 toes pointed = good
 feet touching = good
 no splash = high points
 ripples = lower points
 diver straight up and down on entry to water = good
You
might be surprised how good the students get at this.
5.
Discuss why the highest and lowest scores are discarded. Take not
of which judges have their scores disallowed. Are there any patterns
happening here? :)
6.
Extension  Is there a great deal of difference between taking an
average of all five scores and multiplying by the degree of difficulty
verses the Olympic scoring method? Devise an investigation that will
help us work out the answer to this problem. Present your findings
to an audience.
NB
In the Youtube video above the scoring is done differently as there
are seven judges. The highest and lowest scores are still eliminated
and the remaining numbers added but then this number is multiplied
by 3/5 and then multiplied by the degree of difficulty.
Hint
 label your media clearly so you can find it next year and then remember
to record a new video each Olympic year :)
