Poverty ‘ages’ genes of young children, study shows

aljazeeraamerica:

The stress of growing up in a poor and unstable household affects children as young as 9 years old on a genetic level, shortening a portion of their chromosomes that scientists say is a key indicator of aging and illness, according to a study released Monday. The researchers say their findings are the first that document this type of genetic change among minority children, and make a strong case for the importance of early-childhood intervention in vulnerable communities.

Researchers examined the DNA of a small group of 9-year-old African-American boys who had experienced chronic stress as a result of growing up in families with poor socioeconomic status. They found that the boys’ telomeres were shorter than those of boys the same age and ethnicity who came from advantaged families.

Reading is Not Formulaic: Why Equations Can’t Be Sole Determinants of Student Texts

There’s more to reading than simple properties of words and sentences. There’s building meaning across sentences, and connecting meaning of whole paragraphs into arguments, and into themes. Readability formulas represent a gamble. The gamble is that the word- and sentence-level metrics will be highly correlated with the other, more important characteristics. 
It’s not a crazy gamble, but a new study (Begeny & Greene, 2014) offers discouraging data to those who have been banking on it.

Study Links Teacher ‘Grit’ with Effectiveness, Retention

In recent years, we’ve heard a lot about gritty students.  Now grit researchers are turning their attention to teachers. In a study published in the current issue of the peer-reviewed journal Teachers College Record, University of Pennsylvania researchers Claire Robertson-Kraft and Angela Duckworth found that, for novice teachers in high-poverty school districts, higher levels of  ”perseverance and passion for long-term goals”  (aka “grit”)  were associated with higher rates of effectiveness and retention.

Your memory is no video camera: It edits the past with present experiences

Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new study. In terms of accuracy, it’s no video camera. Rather, memory rewrites the past with current information, updating your recollections with new experiences to aid survival. Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.

Study: Shy Kids Know the Answer—They Just Won’t Say It Out Loud

This is a good moment to be an introvert. A host of books and articles have been published in recent years extolling the virtues of being reserved, and defending inhibited personalities from the longstanding cultural belief that being outgoing and gregarious is the key to success. 
A new study from researchers at the University of Colorado and the University of Connecticut is the latest good news for quieter people. Researchers have long found that socially inhibited kids appear to have weaker language skills than their more outgoing peers. This new study complicates that picture slightly. After examining 408 same-sex twin pairs at the ages of 14, 20, and 24 months, the researchers found that inhibited kids didn’t actually know less—they were simply less eager to express their knowledge out loud.

Personalized Computer Review Improves Student Performance

A new study discovered computer-mediated personalized review helped students remember significantly more material on a tests given at the end of the semester and a month later. 
“Our research shows that data collected from a population of learners can be leveraged to personalize review for individual students, yielding significant benefits over one-size-fits-all review,” said researcher Robert Lindsey, a doctoral student at the University of Colorado, Boulder.
