Mathematics Wed, 27 Jan 2021 09:20:23 ESTnews530961617Researchers find value in comparison of multiple strategies for mathematics teaching and learningHow can cognitive science principles support the deepening of mathematics education? A team of researchers from Vanderbilt University's Peabody College of education and human development and Harvard University's graduate school of education explored how using a basic learning process—comparison—could lead to stronger outcomes for K-12 students in mathematics, and analyzed different approaches for incorporating comparison into curriculum. A summary of the research findings from Peabody College researchers Bethany Rittle-Johnson and Kelley Durkin, in collaboration with Jon Star from Harvard University, was recently published in the December 2020 edition of Current Directions in Psychological Sciences.

While the color or size of an object can be easily described, the description of a shape is more complicated. In a study now published in Nature Communications, Jacqueline Nowak of the Max Planck Institute of Molecular Plant Physiology and her colleagues have outlined a new and improved way to describe shapes based on a network representation that can also be used to reassemble and compare shapes.

However, reliable data is often expensive and difficult to obtain, or too sparse to allow for accurate predictions.

When modeling these processes, it is difficult to capture this complex transition, making the conditions that affect the tipping point a challenge to uncover.

In some contexts, the connections are symmetric, but in many they are directed, for example, indicating flows from one unit to another or which units affect which other units.

Radboud mathematician Walter van Suijlekom explains in a new publication in the journal Communications in Mathematical Physics on 14 July. "We can compare this to MP3s: with a limited range of sound waves, we easily get the impression we are listening to an analogue recording of music." This finding eventually means that we should be able to calculate the shape of our universe.

Minecraft is a sandbox video game released in 2011, where the gamer can build almost anything, from simple houses to complex calculators, using only cubes and fluids. These countless possibilities are what lured David Strütt into Minecraft's universe: "the game might be first intended for kids but I was studying for my Bachelor's degree in mathematics when I discovered it. I fell in love with the game when I realized there is all the necessary blocks to build a Turing machine inside the game. It was a long time ago, so I have since forgotten what a Turing machine is. But the gist of it is: anything is possible inside the game."
