The problems of Merit Pay

The problems of Merit Pay:

If you have been following any of the Wild Rose Alliance Educational polices in Alberta, you will find that they are a supporter of Merit Pay in Education.

What is Merit Pay?
Teachers, and others in education, will be paid based on the results their students attain on standardized exams. At first glance, this sounds great. If a business is rewarded, with more profit, as their sales increase, why shouldn’t teachers get paid more if their results increase?

The problem…
Without getting into truth behind standardized exams, I am going to address the real issues, but first let’s take a look into history..

We start in 1887 in Denver Colorado where the government tested students to determine how much a teacher was worth. David Berliner and Sharon Nichols’ wrote about this experience in Collateral Damage, here is an excerpt:

Another warning about the dangerous side effects of high-stakes testing surfaced, when a plan to pay teachers on the basis of their students' scores was offered, making student test scores very high stakes for teachers. A schoolmaster noted that under these conditions, "a teacher knows that his whole professional status depends on the results he produces and he is really turned into a machine for producing these results; that is, I think unaccompanied by any substantial gain to the whole cause of education."


We then travel to mid 19th-Century England, where a “payment by results” plan was implemented into the Education act. Wade Nelson, a professor at Winona State University, summarized the evaluation saying “Schools became impoverished learning environments in which nearly total emphasis on performance on the examination left little opportunity of learning”.

In The Public Interest, a right-wing policy journal, two researchers concluded with apparent disappointment in 1985 that no evidence supported the idea that merit pay "had an appreciable or consistent positive effect on teachers' classroom work." Moreover, they reported that few administrators expected such an effect "even though they had the strongest reason to make such claims."

Educational historians David Tyack and Larry Cuban have clearly stated that "The history of performance-based salary plans has been a merry-go-round. In the main, districts that initially embraced merit pay dropped it after a brief trial." But even "repeated experiences" of failure haven't prevented officials "from proposing merit pay again and again."

Lastly, the Alberta Teachers Association opposes Merit pay on the following grounds:
• no agreement exists on what constitutes “good” teaching;
• no reliable measure of teacher efficiency exists;
• merit pay undermines teacher morale;
• merit pay is not a quick-fix scheme for any ills that might affect a particular jurisdiction;
• it doesn’t save money;
• it is not a “magic bullet” for increasing student performance; and
• individual merit pay works for few organizations today because most emphasize teamwork and collegiality.

If we start basing salaries on the results of achievement in schools, then achievement, not learning, will be the focus.

The power of Twitter

Recently, a student of mine needed some help. Instead of giving up, she picked up her phone, logged onto Twitter, and her and I had the following conversation:






She was able to explain her thought process in under 144 characters. What happened next, made me smile even more!! I asked her if she understood the first concept of the class, when she expressed that she has not had a chance to look at it yet, something amazing occurred. Check below:




Liam, graduated from Notre Dame last year, and because of the power of the virtual world, is able to assist students who are now enrolled in the course he excelled at!!
Lastly, Twitter is free and the possibilities are limitless!

Cut the Rope in math class.

I provided my students with a laptop, which had Geogabra on it, and the following picture:

I then showed, on my iPad, how the rockets travels around the point.  When the rope is cut, the rocket will fly tangent to the curve.

I used this in my calculus class and asked "Determine the exact location the rocket should be when the rope is cut"

Students determined the equation of the circle, found the derivative and made it equal to the slope between any point (x,y) on the circle and the co-ordinates of the mouth of the monster (or goblin).
**WARNING, this is a hard question**

After, I was thinking this could be used in lower classes, by changing to one the questions below:

  •  allow students to use the tangent button on geogabra, and ask for the reference angle.
  • Determine the amount of time which should pass before cutting the rope.
  • There are always two tangent lines on a circle through an exterior point, are there two times you could cut the rope in the picture?
There are more I could think of.

My students enjoyed the activity, and feel free to change and adapt as you see necessary.

Angry Birds and calculus:

First provide the students with a laptop with Geogebra, and the following photo.


Introduce the meaning of Piecewise functions, and how the yellow bird, when clicked, shoots off at a tangent to the curve.

Ask the students to describe what are the two functions that create this curve (Parabola and a line).

Using prior knowledge have students graph the maximum point on the parabola, and use the dot where the yellow bird took off at a tangent (B), to create the equation of the parabola.  Have students graph the parabola in geogabra, overtop the picture, to ensure all calculations have been done correctly.

Next, ask students how to determine the equation of line.

We will need either a) two points or b) a slope and a point.  Both of which is impossible, without the use of the tangent button in Geogabra.  I explained, we can calculate this without that button!

Have students pick another “point on” the parabola (c), and to calculate the slope between B and C.  Ask how do we make this slope more accurate to the slope of the tangent…

Move C closer to B..

Have students move C closer to B, while still staying on the parabola and calculate the new slope.  Eventually move C as close as possible to B.  The slope should be -0.5  Below is a picture of one of the students’ work


Next using the point B and the slope you can create the equation of line.

From here your choice for extensions: I had students graph the piecewise functions on their calculator and got the following image

Lastly, here is a video on how to determine the slope at a point:
