Recently a teacher friend of mine asked me for some files related to a class I used to teach. I responded with an ebullient “Yes!” As a teacher, I am often reminded that I stand on the shoulders of giants and that it makes no sense to re-invent the wheel when so many talented teachers are willing to give you what amounts to their life’s work…for free. I decided to make my work I gave her a Creative Commons License. It allowed her to use the work but could not sell it.
I am firm believer that knowledge should be free and accessible, however I am not naive, and should you give stuff away you should provide a license. This protects you and the recipient from any future misunderstanding regarding your works.
Among many facts learned was this (and it probably goes without saying but who knew?):
Not all olive oil is the same and the lack of a regulatory body (in the US OR Europe) for olive oil means that labels such as 100% Extra Virgin in the US don’t carry much meaning. Suggesting the olive oil you are buying may have been “cut” with anything but to make it cheaper.
On his website Truth in Olive Oil, Tom gives a couple suggestions of quality “real olive oil” brands and that real olive oil when drunk (yes, as in a shot-glass just like you might whiskey) should give you a slight burning sensation in the back of the throat.
Taking his advice, my wife and I have found a good brand that, while costs about 2x more (10 dollars a bottle), is pretty good stuff. You can find it at Wal-Mart, Harris-Teeter and other fine grocery purveyors.
Having now sufficiently seen and considered the achievements of all those who count themselves masters and artificers of instruments of war, and having noted that the invention and performance of the said instruments is in no way different from that in common usage, I shall endeavour, while intending no discredit to anyone else, to make myself understood to Your Excellency for the purpose of unfolding to you my secrets, and thereafter offering them at your complete disposal, and when the time is right bringing into effective operation all those things which are in part briefly listed below:
I have plans for very light, strong and easily portable bridges with which to pursue and, on some occasions, flee the enemy, and others, sturdy and indestructible either by fire or in battle, easy and convenient to lift and place in position. Also means of burning and destroying those of the enemy.
I know how, in the course of the siege of a terrain, to remove water from the moats and how to make an infinite number of bridges, mantlets and scaling ladders and other instruments necessary to such an enterprise.
Also, if one cannot, when besieging a terrain, proceed by bombardment either because of the height of the glacis or the strength of its situation and location, I have methods for destroying every fortress or other stranglehold unless it has been founded upon a rock or so forth.
I have also types of cannon, most convenient and easily portable, with which to hurl small stones almost like a hail-storm; and the smoke from the cannon will instil a great fear in the enemy on account of the grave damage and confusion.
Also, I have means of arriving at a designated spot through mines and secret winding passages constructed completely without noise, even if it should be necessary to pass underneath moats or any river.
Also, I will make covered vehicles, safe and unassailable, which will penetrate the enemy and their artillery, and there is no host of armed men so great that they would not break through it. And behind these the infantry will be able to follow, quite uninjured and unimpeded.
Also, should the need arise, I will make cannon, mortar and light ordnance of very beautiful and functional design that are quite out of the ordinary.
Where the use of cannon is impracticable, I will assemble catapults, mangonels, trebuckets and other instruments of wonderful efficiency not in general use. In short, as the variety of circumstances dictate, I will make an infinite number of items for attack and defence.
And should a sea battle be occasioned, I have examples of many instruments which are highly suitable either in attack or defence, and craft which will resist the fire of all the heaviest cannon and powder and smoke.
In time of peace I believe I can give as complete satisfaction as any other in the field of architecture, and the construction of both public and private buildings, and in conducting water from one place to another.
Also I can execute sculpture in marble, bronze and clay. Likewise in painting, I can do everything possible as well as any other, whosoever he may be.
Moreover, work could be undertaken on the bronze horse which will be to the immortal glory and eternal honour of the auspicious memory of His Lordship your father, and of the illustrious house of Sforza.
And if any of the above-mentioned things seem impossible or impracticable to anyone, I am most readily disposed to demonstrate them in your park or in whatsoever place shall please Your Excellency, to whom I commend myself with all possible humility.”
New research from the Alliance for Excellent Education on the teaching profession has recently come out. Pretty much says the same stuff that every survey or analysis of the teaching profession says, namely teachers quit for one of three reasons: low Pay, lack of collaboration, lack of administrative support. One interesting conclusion does jump-out:
“Since the mid-1980s the significant expansion of the teaching workforce has been accompanied by increased turnover among beginning teachers.”
This implies a revolving-door for the teaching profession: more first-year teachers come in, teach for a couple-years, leave, only to be replaced by more first-year teaches. While this may come as a shock, it simply mimics economic conditions: a decline of middle-class professions (of which teaching is rapidly becoming neither) and an emphasis on short-term gains at the expense of long-term investment.
I was fortunate that I had a solid first-three years with some great mentors. However, the fault-lines of a decade of teaching are getting wider and wider each year with no end in sight.
