The Australian Curriculum appears to have the same major flaw as State Curricula.
Some years ago I was teaching in a New South Wales Government School which had a significant aboriginal population. I was given the "bottom" year eight class and directed to teach them mathematics. Accordingly the Head Teacher gave me a copy of the common year eight syllabus and program.
My first lesson was centred around diagnostic testing. There were seven students in the class with three support persons present. For the next ten weeks I, the seven students, and three support persons made great progress which resulted in all students increasing their mathematical abilities and more importantly broadening their social skills.
With the end of term one now upon us the Head Teacher asked me for my program register. I stated that I had not quite finished writing my program and that I would have it written and signed off by the beginning of term two. He reminded me that he had given me a copy of the year eight common program at the beginning of the term. I told him that the material he had given me was unsuitable and was not teachable to those students. I also pointed out that it is impossible to teach the unteachable.
He was not happy! For the remainder of the year my class continued to make very good progress. The Head Teacher did not speak with me again regarding that class. In fact, he hardly spoke to me for the rest of the year.
The following year another teacher took the "bottom" year eight class. I later found out that he also threw out the common curriculum and taught a more suitable course of study. Apparently he and his class had a very fruitful year.
Having entire year groupings in mathematics and science follow the same curriculum in each of those subjects is fundamentally floored.

DRUGS IN SCHOOLS
It is commonly thought that the major drug problems in some schools are related to substances such as "ice", cocaine, marijuana, etc or alcohol.
This is far from the truth. The biggest single drug problem in virtually all primary and secondary schools is smoking.
There are numerous reasons as to why students start smoking. It is my experience that the majority of students over 15 years of age want to give up their addiction.
In the past I have, "unofficially", helped students to give up their addictive habit. I point out to them that as I see it there are only three reasons why they continue to smoke. One they are stupid, or two the are addicted, or three they are both stupid and addicted. None of the students which I have helped to quit were stupid.
I would suggest that most schools do not want to admit that they have a smoking problem. It's an "image of the school" thing. I would also suggest that the so called educational programs related to smoking which are implemented in schools are generally a waste of time and money. They almost certainly do nothing for the many students who are addicted. It is completely understandable that the vast majority of addicted students cannot get through a school day without having a puff or two.
Many of the punishments which teachers dish out to students who are caught smoking are quite pathetic and do nothing to alter the students addiction.
If we want a society where a lot less people smoke then we need to properly address the problem of smoking in our schools.

Images and Institutions
It is important for institutions such as churches and schools to maintain a positive image. Hence, leaders of these organisations are hand picked for this purpose.
I remember attending a staff meeting where a child protection issue was raised. A member of staff strongly suggested that every thing be kept "in house". That staff member was later promoted to the position of Deputy Principal and then Principal.
I suggest that this sort of action sends a clear message to staff members in both churches and schools.

VIOLENCE IN SCHOOLS
It seems that violence in schools throughout Australia is on the increase. Most Principals, and their executive staff, are committed to maintaining a positive image for their school. Hence, it is not too difficult to imagine that some classroom teachers and some students who have been subjected to violence are "sacrificed" for the sake of maintaining school image.
The Federal Government publishes certain statistics regarding schools. I always suggest to parents that the first set of data to view is school attendance rates. I further suggest to the same parents that if attendance rates are below 95% then it is quite possible that there is a significant problem with violence at the related school.
It is my experience that school attendance rates are over estimated and hence absenteeism is underestimated.

Zero
Numerous teachers of mathematics will tell you that x/x = 1, (x+1)/(x+1) = 1, (x-7)/(x-7) = 1, etc.
This is not quite correct. If x = 0, then x/x does not equal one. There is no inverse for zero and hence 0/0 has no answer.
In the second example above if x = -1 we again have 0/0. In the third example if
x = +7 we again have 0/0.
Hence, (x +9)/(x+9) = 1, but x cannot equal -9 is the complete answer.
Suppose you graph y = (sine x)/x. When x = 0 we have y= (sine x)/x = 0/0. Hence at x = 0, y = 0 on the number plane we put in a discontinuous point.

RECYCLED WATER
Some communities in Australia refuse to drink recycled water. Some people say that they will never drink recycled water.
About 2000 years ago a Roman soldier dies in a secluded part of the North African desert. His body slowly decomposes and his water molecules evaporate into the atmosphere. From there his molecules become part of the world's water cycle. After 2000 years his molecules could be in the Indian Ocean, the Pacific Ocean, your local lake, your local water supply, etc.
One day you decide to drink a litre of water from your kitchen tap (this tap could be "anywhere" in the world). What is the most probable minimum number of water molecules that you will drink which were once in this soldiers body?
Most of my students usual guess between zero and one hundred. Onto the whiteboard I put up 0, 10,100,1000,...................1,000,000,000,000. I put the numbers up in powers of ten with the last number being ten to the power of 12. My students are asked to guess the closest number to the estimated answer.
The most probable minimum number is about 20,000,000 (20M). Hence, ten to the power of seven is the closest number which they can guess.
We ALL drink recycled water. The next time you drink a can of coke (which is mainly water) try estimating the minimum number of molecules which came from that Roman soldiers body!
