Researchers have shown that districts around the country dont use the same criteria when grouping students into higher or lower math classes. Thats in part because algebra is considered a critical point in the race to calculus. Critics also challenged the arguments and data used by the district to justify the policy.
That’s the argument of Peter Liljedahl, a professor of mathematics education at Simon Fraser University in Vancouver, who has spent years researching what works in teaching. These are the students who end up hitting a wall when math courses move from easier algebra to more advanced concepts in, say, calculus, he argues. “At
That left the family to decide whether to make him repeat the class in ninth grade — and potentially disadvantage him by preventing him from taking calculus later in high school — or to have him push through. For some researchers, California misstepped. It’s a phenomenon researchers are painfully aware of.
But while working with schools and colleges across the globe as we conducted research for our book , we realized that most interventions don’t address systemic issues causing mental health problems in the first place. Indeed, a meta-analysis of research on this issue found a correlation between homework and achievement.
For this week’s EdSurge Podcast, we talked with Khan to hear more about his vision of AI tutors and the arguments from his recent book. You note in your book that back when you were an undergraduate at MIT, you originally wanted to be an AI researcher. What would you say to that argument? Why were you drawn to that area?
too—delivering the latest from our long-term research and development pipeline. Across the 35 years since Version 1 we’ve been able to continue accelerating our research and development process, year by year building on the functionality and automation we’ve created. But while LLMs are “the biggest single story” in Version 13.3,
He starts off by saying about Carnot’s book: The idea which serves as a basis of his researches seems to me to be both fertile and beyond question; his demonstrations are founded on the absurdity of the possibility of creating motive power or heat out of nothing.
I’ve learned Python over the last three years along with some of its related systems like NumPy and SciPy , and I’ve successfully used Python as a tool in my research. Can anyone seriously imagine banning microscope technology from the biology major, on the argument that biology is a more pure discipline without the technology?
Researchers and policy makers have pushed to open that gate—providing more students access to algebra, focusing in particular on those students historically denied access to higher-level mathematics. In its current form, school algebra serves as a gatekeeper to higher-level mathematics. Boaler & Leavitt, 2019).
we’ve been steadily delivering the fruits of our research and development in.1 In a somewhat different direction, we’ve expanded our Wolfram Summer School to add a Wolfram Winter School , and we’ve greatly expanded our our Wolfram High School Summer Research Program , adding year-round programs , middle-school programs , etc.—including
Some involve alternate functional forms; others involve introducing additional functions, or allowing multiple arguments to our function f. But it turns out that the fact that this can happen depends critically on the Ackermann function having more than one argument—so that one can construct the “diagonal” f [ m , m , m ].
But if you were reading a research article and the author used a sample size of n = 1, how would you react? An argument for traditional grading goes like this: Sure, a single assessment might have a grade on it that doesn't accurately reflect student understanding. It makes sense as long as you don't think about it.
While all of this was going on, I was also energetically pursuing my “day job” as CEO of Wolfram Research. In the end—after all sorts of philosophical arguments, and an analysis of actual historical data —the answer was: “It’s Complicated”. And I’m happy to say that just three years later, we’ve already made a big dent in it.
It didn’t help that his knowledge of physics was at best spotty (and, for example, I don’t think he ever really learned calculus). In the mid-1990s, researching history for my book A New Kind of Science , (as I’ll discuss below) I had a detailed email exchange and long phone conversation with Ed about this. It’s just my nature.
Sometimes textbooks will gloss over everything; sometimes they’ll give some kind of “common-sense-but-outside-of-physics argument”. Once one has the idea of “equilibrium”, one can then start to think of its properties as purely being functions of certain parameters—and this opens up all sorts of calculus-based mathematical opportunities.
My argument is that computer science was originally invented to be taught to everyone, but not for economic advantage. Alan Perlis (first ACM Turing Award laureate) made a different argument in his chapter. He argued that you can’t think about integral calculus the same after you learn about computational iteration.
