The Trouble with Discovery Learning
GUEST BLOG BY SARAH WARRY-POLJANSKI, SQE DIRECTOR
In a recent news article, the majority of math professors from across the country stated that discovery- based learning is not working. The statistics are clear, math scores are plummeting and it coincides with the discovery- based model.
With the Ontario government's commitment to 60 million dollars to be spent on math programs and the introduction of a mandatory one hour of math a day, it is wise to first examine whether this will solve the problem or make it worse?
My opinion is that it will only make it worse and will cost taxpayers another $60 million plus in the long run. This is money that could be going towards other much-needed educational, social, and health services for children across the province.
Others share this opinion as well (see the 1,219 comments to the linked-to article), and a call for a curriculum change is what most of the math experts are recommending in order to bring about a reversal of the downward trend.
The issue with discovery- based learning is that too much emphasis is focused on how to find the answer, and not the answer itself. It leaves children feeling as if they are constantly trying to solve a puzzle, but they never get a clear view of what the finished product is, nor the ability to retain the image for future use.
When you use discovery-based learning, the frontal lobe of the brain where our "working memory" is located, becomes overworked and tired as it's constantly processing information. Traditional methods, like rote learning which emphasizes the memorization of the formula and the final product (like the times table), allow the information to be transmitted to and stored in the limbic system - the area of the brain responsible for learning and long-term memory. China and other Eastern countries are top rote-style teachers.
If we compare ourselves to modern day computers, it would resemble having 50 windows open and running simultaneously, overworking our computer, slowing the system down, and ultimately crashing it. Whereas if we "saved" the information, we could recall it when needed and close it when finished.
Another red flag with discovery-based learning and the overuse of our working memory is that students with learning disabilities, due to a poor working memory, are at an even higher risk of being unsuccessful with this model.
With all of this information available to us, and the majority of professional opinions pointing to a change in curriculum being the answer, it leaves one wondering why the government is hesitant to make the proper changes and do what's logical and reasonable.
