Debunking the Dunning-Kruger effect – the least skilled people know how much they don’t know, but everyone thinks they are better than average

The idea that the least skilled are the most unaware of their incompetency is pervasive in science and pop culture. But a new analysis of the data shows that the Dunning-Kruger effect may not be true.

Dobble: what is the psychology behind the game?

Dobble is a card game that originated in France in 2009. It involves observation, articulation and speed.

If 1% of COVID-19 cases result in death, does that mean you have a 1% chance of dying if you catch it? A mathematician explains the difference between a population statistic and your personal risk

It’s not entirely accurate to say that you’re more likely to die in a car accident than in a plane crash. Chances are, you’re not the average person.

Declines in math readiness underscore the urgency of math awareness

Nearly four decades after President Ronald Reagan proclaimed the first National Math Awareness Week, math readiness and enrollment in college math programs continue to decline.

Cancer evolution is mathematical – how random processes and epigenetics can explain why tumor cells shape-shift, metastasize and resist treatments

An epigenetic model of cancer that incorporates the concept of stochasticity could also explain why cancer risk increases with age and how biological development can be reversible.

‘Numberless math’ gets kids thinking about and visualizing algebra

Working with moveable pictures can help children learn an algebra rule: Whatever you do to one side of the equation, you need to do to the other. Here’s how teachers or caregivers can lead this.

Why teachers are letting students solve math problems in lots of different ways

Mathematics is not a “neutral” subject — cultural biases exist. A shift to more equitable teaching looks like teachers drawing on students’ knowledge, and students generating lots of solutions.
