The far side of Educational Reform


Teachers are at the far end of educational reform. 

Great start of the 


Apart from students and parents, they are often the very last to be consulted about and connected to agendas of what changes are needed in education, and of how those changes should be managed. Educational change is something that government departments, venture philanthropists, performance-driven economists and election-minded legislators increasingly arrogate to themselves. Even when these policy-setting and policy-transporting bodies speak on behalf of teachers, teachers often have little or no voice. Teachers are rarely asked to speak on their own account.

Not surprisingly, therefore, teachers are also often at the far end with educational reform. They are at the end of their tether. Targets and testing, capricious and contradictory changes, political climates that feed on failure and foment professional fear, insecurity and instability, cut-throat competition and rampant privatization – these are the enemies of teaching that erode confidence and betray trust throughout the teaching profession, although they are more prominent south of the border than within Canada itself. However, less obvious adversaries in Canada and elsewhere can still make teachers feel at their wits end today. Hackneyed harangues against whole-class teaching that equate it with factory-style schooling; excessive exaltation of technologically-driven instruction; reduc-tion of deep
personalization to slick customization; data warehouses that drive teachers to distraction; and exploitation of international performance comparisons to the domestic disadvantage of public school teachers in almost every devel- oped country – these are the gimmicky
Goliaths of educational change today. They are the surreal Far Side of school reform.
If it is indeed the case, as is now commonly claimed, that the teacher is the most important within-school influence on a child’s educational achievement, then it is time to stop insulting teachers, excluding teachers and inflicting change after change upon them. It is time to bring teachers back in: to make them part of the solution and not just part of the problem.
THREE WAYS OF CHANGE The First Way of Change
How did we get to this position where teachers are always the objects and never the subjects of change, where leaders say they esteem teachers on the one hand and then on the other hand assume that teachers know little about how to improve teaching and learning?
When international delegations visit
high performing jurisdictions, including
those in Canada, it is not teachers
they typically get to meet but
rather ministers, administrators and
advisors – those who command
and commandeer a view from the top, along with an
official version of what everyone else is supposed to see. This is not only a bias of judgment, but it leads to a bias of evidence and perception. Diane Wood’s research (2007) has shown that professional learning communities, like many reforms, are often viewed more favourably by people at the top than by those at the bottom. Quantitative survey research on leadership and trust, reveals that “site and district administrators view themselves...and each other...as exhibiting trust behaviors consistently higher 

Teachers; more than "teach"ers

Julie changes one student every day as he is mentally unable to change himself.  She has to wipe, clean, undress and dress this student every single day.

Jason, after school, coaches 15 boys basketball.  He has to plan drills, prepare his students both mentally and physically for the next game, book hotels and busses, and ensure each player is caught up in all classes.

Lindsey listened in silence as her student confessed that one night she drank too much and danced naked in front of other students.  After calling a counselor and organizing a third party psychologist to come in, Lindsey watched for days as this student dealt with turmoil, bullying, and public ridicule.  Through various supports, which Lindsey organized, this student over came this incidence and regained her mental health.

Chris wakes up every morning at 5 am to ensure he is at school to drive the cross-country running team on the bus.  Being one of the few teachers who have a bus license, he is called to drive the team to and from the track every morning.  While they train, Chris sits, enjoys a book, listens, and waits for the coach, whom is another teacher, to finish the daily training so he can drive the students back.

Brenda spent her Saturday on the phone with local RCMP discussing the mental health of a suicidal student.  She then drove to the hospital to sit with the student, as his family abandoned him and Brenda was the closest person he had left.  Only knowing the student for 3 months, she had very little information to give to the RCMP however the time she spent with him on Saturday may be the only reason he is alive today.

Carol has students who arrive to school starving.  Knowing that it is hard to focus when your stomach is louder than the people around you, she cooks a simple breakfast in her classroom every morning.  Usually coming out of her own pocket, she shops once a week to buy bagels, bread, eggs, fruit, and other simple breakfast items. 


The root word of teacher may be “teach” however this word represents only a part of the day of a teacher.   Teachers do teach, as well as act as parents, friends, shoulders, counselors, emergency contacts, cooks, bus drivers, coaches, and most importantly non-judgmental people.

TV around a corner

What is the largest TV that could fit around a corner in your house?

This was the question we answered in my calculus class.

First I showed this applet and had students play with it




Next I asked what do we need to know?

Students asked for the width of the hallways which are 0.8 m and 0.9 m wide.

Next we realized that actually to determine the largest TV we actually need to MINIMIZE the length of the line.  As the smallest line will be the line that can fit around the entire corner.

Calling the, angle between the TV and the 0.8 m wall, theta you get the equation of the TV length at any angle to be



Next taking the derivative, and solving for when it equals 0, gives us


Substituting this back into the equation gives us a TV (or any rigid object) with a length of 2.4 m or 94.45 in across.  

We then did have a discussion around what assumptions are we making?  Some are...
  • The TV has no depth at all
  • The TV will scrap across the wall
  • The TV is out of the box
