Math anxiety causes trouble for students as early as first grade

ScienceDaily (Sep. 12, 2012) ? Many high-achieving students experience math anxiety at a young age -- a problem that can follow them throughout their lives, new research at the University of Chicago shows.

In a study of first- and second-graders, Sian Beilock, professor in psychology, found that students report worry and fear about doing math as early as first grade. Most surprisingly math anxiety harmed the highest-achieving students, who typically have the most working memory, Beilock and her colleagues found.

"You can think of working memory as a kind of 'mental scratchpad' that allows us to 'work' with whatever information is temporarily flowing through consciousness," Beilock said. "It's especially important when we have to do a math problem and juggle numbers in our head. Working memory is one of the major building blocks of IQ."

Worries about math can disrupt working memory, which students could otherwise use to succeed. Beilock and other scholars have studied this impact of anxiety on working memory on older students, but her current work is the first to explore the impact on students as they begin school.

The findings are published on the website of the Journal of Cognition and Development. The lead author is UChicago PhD candidate Gerardo Ramirez. Joining he and Beilock in the work are UChicago postdoctoral scholar Elizabeth Gunderson and Susan Levine, the Stella M. Rowley Professor in Psychology.

The team showed that a high degree of math anxiety undermined performance of otherwise successful students, placing them almost half a school year behind their less anxious peers, in terms of math achievement.

Less talented students with lower working memory were not impacted by anxiety, because they developed simpler ways of dealing with mathematics problems, such as counting on their fingers. Ironically, because these lower-performing students didn't use working memory much to solve math problems, their performance didn't suffer when worried.

"Early math anxiety may lead to a snowball effect that exerts an increasing cost on math achievement by changing students' attitudes and motivational approaches towards math, increasing math avoidance, and ultimately reducing math competence," Beilock writes in the article.

For the study, the researchers tested 88 first-graders and 66 second-graders from a large urban school system. The students were tested to measure their academic abilities, their working memory and their fear of mathematics. They were asked, on a sliding scale, how nervous they felt to go to the front of the room and work on a mathematics problem on the board.

The study found that among the highest-achieving students, about half had medium to high math anxiety. Math anxiety was also common among low-achieving students, but it did not impact their performance.

Fortunately, there is hope for alleviating the negative impact of math anxiety on math achievement. "When anxiety is regulated or reframed, students often see a marked increase in their math performance," the researchers write. One way to reframe anxiety is to have students write about their worries regarding math ahead of time.

A procedure termed "expressive writing" helps students to download worries and minimizes anxiety's effects on working memory. The researchers speculate that, for younger students, expressive picture drawing, rather than writing, may also help lessen the burden of math anxiety. Teachers can also help students reframe their approach by helping them to see exams as a challenge rather than as a threat, the researchers write.

Beilock is also an author of "Math Anxiety, Who Has it, Why it Develops and How to Guard Against it," published in the current issue of Trends in Cognitive Science (Tics). The article, co-written with UChicago postdoctoral scholar Erin Maloney, points out that math anxiety has a variety of sources.

"Its development is probably tied to both social factors, such as a teachers' and parents' anxiety about their own math ability and a student's own numerical and spatial competencies," they write.

The research for the paper in the Journal of Cognition and Development was supported by the National Science Foundation Science of Learning Center Grant; a grant from the Spatial Intelligence and Learning Center to Beilock and Levine; by a NSF CAREER grant to Beilock; and by a National Center for Education Research Grant.

The research in the paper published in Trends in Cognitive Science (Tics) was supported by a U.S. Department of Education, Institute of Education Sciences Grant and a NSF CAREER Award to Beilock.

Beilock, the author of Choke, What the Secrets of the Brain Reveal about Getting it Right When you Have To, is one of the nation's leading experts on the power of anxiety to undermine performance across a wide variety of fields from test taking, to public speaking, to your golf score.

She's not chubby, she workout routines a number of instances a week and was truly a vegetarian for properly about a ten years. Everyone, such as her medical professionals, was a little bit baffled. She shares my fairly fierce sweet tooth, so we sat down collectively very last week to brainstorm a several recipes that would help her start to rethink the way she prepares her favorite system of the day: dessert.

We made a decision not to go way too drastic for anxiety that she'd turn into discouraged, so we appeared at recipes that lower out egg yolks. We were the two similarly delighted to find a decadent treasure trove of incredible treats.

From sorbets and frozen yogurts to truffles, macarons, and pavlovas, you can find a full huge, broad entire world of yolk- free of charge, egg- cost-free, and vegan desserts out there that I began bookmarking. All of the recipes underneath don't claim to be body fat - cost-free or cholesterol cost-free necessarily. Some consist of quite a bit of cream even though others are practically unwanted fat - totally free. The place was to do some first discovering, and to get actually fired up about pudding, cake, fondue and sorbet. We succeeded.

Norway 2013 Oil Investments Adjusted Up To NOK204 Billion

The expected record investments in Norway's oil and gas sector in 2013 were adjusted up in the third quarter survey, official data showed Thursday.

The oil and gas investments in the country's lucrative offshore sector are expected to be 204 billion Norwegian kroner ($35 billion) in 2013, according to the third quarter survey, Statistics Norway said, the highest estimate since the agency started measuring oil investments in 1985.

The 2013 estimate was NOK9.8 billion higher than in the second quarter survey, the agency said.

Oil and gas investments in 2012 were adjusted slightly down to NOK184.9 billion.

The quarterly petroleum investment statistics are based on estimates submitted from oil and gas companies operating offshore Norway.

The biggest part of the investments is spent on maintaining output in currently producing fields, and is estimated at NOK96.9 billion, up from an estimate of NOK93.5 billion in the previous quarter.

The biggest investments are expected in giants such as the Statoil ASA (STO)-operated Troll and Oseberg, and the ConocoPhilips (COP)-operated Ekofisk, Statistics Norway said.

Investments in new fields are expected to total NOK62.1 billion in 2013, up from an estimate of NOK61 billion in the second quarter survey.

The most expensive new fields are the Eni SpA (E)-operated Barents Sea field Goliat, the ConocoPhilips-operated Eldfisk II, and the Lundin Petroleum AB (LUPE.SK)-operated Edvard Grieg field, the statistics agency said.

Investments in exploration in 2013 are estimated at NOK40.7 billion, up from the second quarter estimate of NOK35.4 billion.

Oil and gas companies plan a huge increase in the drilling of new production wells and exploration wells in 2013, expecting to spend NOK101.6 billion. This is a significant upward adjustment from the second quarter estimate of NOK93.6 billion.

"There is reason to believe that some wells planned to be drilled in 2013 will be postponed to 2014," Statistics Norway said, due to capacity constraints such as the lack of rigs.

Four new rigs have been added on the Norwegian continental shelf so far in 2012, and two new rigs are expected in early 2013, the agency said.

Several additional projects are expected to be approved by the summer of 2013, including Aasta Hansteen, Draupne and Dagny/Eirin. This will likely increase the 2013 investments even further from today's record levels, according to Statistics Norway.

South Africa: Small Farmers Can Spur Economic Growth

Cape Town ? Smallholder agriculture has potential not only to alleviate poverty in South Africa, but to spur general economic growth, a major conference on combating poverty and inequality has heard.

Given that South Africa's growth is lagging behind that of many smaller African economies, the potential of small farmers to help turn the country around has been a recurring theme in most sessions of the conference.

"While the place of agriculture and its contribution to the gross domestic product has declined over time, it remains an important sector of industry," said Mazibuko Jarra of the University of Cape Town's Law, Race and Gender Unit.

Independent researcher, Stephen Greenberg, added that agriculture and land reform are closely linked and that the lack of access to land has "decimated" small-scale agriculture in South Africa. This impacts on food security as people in rural areas rely on subsistence farming in the absence of economic alternatives.

Land reform, aimed at achieving the transfer of land from white to black farmers, has been a slow and expensive process in South Africa.

Ruth Hall of the Institute for Poverty, Land and Agrarian Studies (PLAAS), noted that the government's land reform policy was based on a "willing buyer, willing seller" principle, because it was perceived to be quicker and relatively cost effective.

Jarra said that while many commercial farmers are now willing to sell due to the economic climate, prices determined by the market are unreasonable. He argued for a re-examination of land expropriation within the context of the country's Constitution.

Greenberg echoed Ben Cousins, also of PLAAS, when drawing a distinction between ownership of and access to land by leasing for example.

Access to credit is a major stumbling block to small-scale farmers.

Greenberg noted that only three percent of the government-backed Land Bank's loan book goes to small farming operations, since policy and support focuses on large scale and corporate agriculture.

"Small scale and decentralised agro-processing is needed in South Africa but this is not possible without state intervention and a break with big industrial agriculture." Jarra added.

The large number of sessions addressing the interlinked issues of access to land, farming and agrarian reform is indicative of the complex and emotive nature of the debates at the conference.

The conference is entitled "Carnegie III: Strategies to Overcome Poverty and Inequality". Two earlier conferences and research programmes, looking at similar issues in the 1930 and 1980s, were funded by the Carnegie Corporation of New York.

DIY News - Power Tools Becoming More Popular Over Hand Tools

Tweet This Recent research and statistics in the field of do-it-yourself construction, repair and home improvement shows that power tools are miles ahead of manual hand tools when it comes to sales and usage by the general public. In the United States alone, the sales of power trade tools is rising consistently at an average of 4.8 percent, and the peak trend is expected to continue until 2016. In other countires where DIY enthusiasts abound even more, such as Australia, the rise of automated tools is evidently more widespread.

More and more people decide to use automated discount tools partly because of the rise of demand in independent construction projects. For example, if a person or family wants to have their house undergo a major reconstruction, they feel they would save more on construction costs if they do the process themselves instead of hiring a third party contractor. Instead of hiring many people to do the task, the family can team up together and use air tools instead to make the workload easier.

By 2016, the power tools industry is expected to become a $13.1 billion dollar industry, the highest it will ever be since 2006, when the tool industry experienced some slight drawbacks. In the United States, many tool suppliers are offering more power equipment because a lot of the clients who left their homes during the recession are now rebounding and embarking into housing projects again.

In Australia, however, the rising costs of house construction expenses in Sydney are forcing residents to choose power tools. This would enable them to remodel their homes without spending too much on hiring a construction team. As one of the most expensive places in the world when it comes to living expenses, families in Sydney are benefitting from do-it-yourself construction and repair.

Meanwhile, hand tools are seen to continue lagging behind hand tools for the upcoming years.It is obvious that people nowadays are choosing more convenience and efficiency when working with tools. Price is only a secondary factor in these kinds of situations.
