New math for old
Michael Zwaagstra had a fascinating op-ed piece in Halifax's Chronicle Herald on Oct. 3. In reporting on Nova Scotia's plan to adopt the Alberta math curriculum. Unfortunately, a while back Alberta fell into the hands of mathematical snake oil peddlars, and the province's math scores are plummeting. Already very low, Nova Scotia's math scores figure to drop even further once the new curriculum has been adopted.
But this was not the most interesting part of Mr. Zwaagstra's piece, in which he described a talk given by one of the head snake oil peddlars, Marian Small. During the course of her presentation, Dr. Small emphasized that there were many ways to get the right answer and teachers should be open to many different techniques. But when Mr. Zwaagstra asked whether teachers should accept the standard algorithms, Dr. Small replied in the negative. And when other members of the audience followed up, Dr. Small shut down their questions and proceeded with her presentation. As Mr. Zwaagstra writes: "It was ironic that Dr. Small emphasized the importance of acknowledging the validity of other perspectives, but did exactly the opposite with her own presentation. She gave a one-sided lecture and refused to seriously dialogue with anyone who expressed an opposing view."
It is actually pretty hard for me to believe that educators are still suckering for these "new" approaches - after some 50 years of experience with their implementation and mountains of research validating standard algorithms. But apparently it is the case.
