This “Rules” notice was seen in one of our Faith Formation classrooms. This used to be the discipline in Catholic Schools and why Catholic Schools generally and regularly through the decades were fully two grades (at least) ahead of all other public schools.
But, of course, discipline means nothing without the interior wherewithal to be disciplined, that is, by way of friendship with God, which we are provided with the Sacraments.
Faith Formation is great, but…. what we really need are Catholic Schools with teaching orders of religious Sisters.
Hey, there’s an idea!
ARISE! LET US BE GOING! 
I was just lamenting to a friend that our Parochial school no longer had any professed religious for teachers. I blamed it on a bad principal, (who I charitably thought to be a nominal Catholic) who refused to renew any of the contracts of our nuns. Of course other Catholic schools snapped them up!
Great “rules”, they still are part of the class constitution in any classes that I teach. They make for happer students no matter the age.
Catholic schools were usually two years / grades ahead of State (government / public) schools in Australia as well. This is no longer the case and hasn’t been for decades. However the Faith and its practice, although severely weakened, is not yet dead and the rules of respectful interaction linger. Consequently, our Catholic school students are generally considered better behaved than their public school counterparts and to have a greater chance than most students of doing well academically.
Re: “… what we really need are Catholic Schools with teaching orders of religious Sisters.” Yes! … Sisters of sound Faith and in their religious habits.
Happily for our diocese we have a small but growing religious order of Sisters that teach – the Conventual Sisters of St Dominic. As it says on their website, “This is not a ‘new’ community with a ‘new’ charism. It has continuity of spirit and tradition with the long history of Dominican women in Ireland and Australia, yet incorporates the vital elements of true renewal and reform desired by the Church in our times”.http://www.conventualsistersofstdominic.org/p/history.html
From what I have read elsewhere the US has more new or reformed religious orders than we have here in Australia. These developments around the world give hope that the restoration of the Church is underway.
