12 Mathematics B – Investigating how OPs are calculated

In 12 Mathematics B this term, students have been learning how to calculate the probability of events that follow a normal distribution, or bell curve.
This week, students used this knowledge to investigate how normal distributions are used to calculate OPs. As a class, we were also able to discuss how student marks, class results and QCS test results are all used to calculate OPs.

At the end of the lesson, we gleaned a few insights and important things to remember as they get closer to finishing 12 years of school. They included:
• The best way to improve your end of year result is to try your hardest and do the best you can. That is all you can control. That is all God expects of any of us.
• It is impossible for one number (whether that be an OP, or an ATAR in a few years under the new system) to completely describe a person. Sure, it gives some indication of how you achieved at school. It does not tell us about what someone is capable of doing in the future. It does not tell us about the passions and gifts a person has. It does not necessarily tell us how hard someone worked. It does not tell us about how each person is made in God’s image and the inherent value that truth gives each of us as people.
• School is important. But there’s a reason why our school motto is ‘Educating for Eternity’. OPs, or ATARs, may help students in the immediate future at university, TAFE and further work. But there is so much more to who we are, including the plans that God has for each of us, and the hope of eternity that God has given us through Jesus Christ.
