A new study finds a free 'massive, open, online course' (MOOC) led to students feeling more positive about math, more engaged during math class, and scoring significantly higher in mathematics assessments. This is the first of its kind to focus on changing students' mindsets and beliefs about their mathematics potential.
Teachers who antagonize their students by belittling them, showing favoritism, or criticizing their contributions can damage their learning potential, a new study warns.
An online study with 168,000 people shows large variation in typing speeds and styles. The dataset is the largest ever on everyday typing and exposed several factors that differentiate fast vs. slow typists. In addition to making less errors, the researchers found that fastest typists rely on so-called 'rollover' where a letter key is typed already before the previous one is released. The data is published and free to use for research purposes.
Research published in PLOS ONE shows that private landowners trust conservation agencies more and have better views of program outcomes when they accompany conservation biologists who are monitoring habitat management on their land.
Researchers at Carnegie Mellon University have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system.
Cows burp up more gas than you might think possible when they're digesting grass. Most of that gas is methane, a potent greenhouse gas, which is bad news for the planet. This video from Reactions explains why the chemistry of cow guts is such a busy area of study.
Students classed as less able are being hindered by being grouped into ability-based sets, according to new research published today in the Cambridge Journal of Education.
Century eggs, or pidan, are a preserved food made by fermenting duck eggs in alkali. The green and black color of these eggs is not very appealing at first blush, and the smell is even worse. However, this Ming dynasty innovation effectively extended the shelf life of eggs and has been adopted as a beloved comfort food in China and throughout the world. Reactions explains the chemistry behind this unusual culinary offering.
