Smartphones may be detrimental to learning process

2015-07-07
(Press-News.org) A yearlong study of first-time smartphone users by researchers at Rice University and the U.S. Air Force found that users felt smartphones were actually detrimental to their ability to learn.

The research paper "You Can Lead a Horse to Water But You Cannot Make Him Learn: Smartphone Use in Higher Education" appeared in a recent edition of the British Journal of Educational Technology. The research reveals the self-rated impact of smartphones among the users.

"Smartphone technology is penetrating world markets and becoming abundant in most college settings," said Philip Kortum, assistant professor of psychology at Rice and the study's co-author. "We were interested to see how students with no prior experience using smartphones thought they impacted their education."

The research revealed that while users initially believed the mobile devices would improve their ability to perform well with homework and tests and ultimately get better grades, the opposite was reported at the end of the study.

The longitudinal study from 2010 to 2011 focused on 24 first-time smartphone users at a major research university in Texas. Prior to the study, the participants were given no training on smartphone use and were asked to answer several questions about how they thought a smartphone would impact their school-related tasks. The students then received iPhones, and their phone use was monitored during the following year. At the end of the study, the students answered the same questions.

When participants were asked to rate their feelings on the following statements specifically related to learning outcomes, such as homework, test-taking and grades, they provided the following answers (one represents "strongly disagree" and five represents "strongly agree"):

My iPhone will help/helped me get better grades - In 2010 the average answer was 3.71; in 2011 the average answer was 1.54. My iPhone will distract/distracted me from school-related tasks - In 2010 the average answer was 1.91; in 2011 the average answer was 4.03. The iPhone will help/helped me do well on academic tests - In 2010 the average answer was 3.88; in 2011 the average answer was 1.68. The iPhone will help/helped me do well with my homework - In 2010 the average answer was 3.14; in 2011 the average answer was 1.49. Kortum noted that the study did not address the structured use of smartphones in an educational setting. He said that the study's findings have important implications for the use of technology in education.

"Previous studies have provided ample evidence that when smartphones are used with specific learning objects in mind, they can significantly enhance the learning experience," Kortum said. "However, our research clearly demonstrates that simply providing access to a smartphone, without specific directed learning activities, may actually be detrimental to the overall learning process."

A key role for CEP63 in brain development and fertility discovered
2015-07-07
Today in Nature Communications, scientists at the Institute for Research in Biomedicine (IRB Barcelona) provide molecular details about Seckel Syndrome, a rare disease that causes microcephaly, or small brain, and growth delays. A joint study conducted by Travis Stracker and Jens Lüders indicates that the protein CEP63 plays a key role during brain development as it is involved in the correct division of stem cells in this organ. Furthermore, the researchers have discovered that CEP63 is associated with sperm production--an unknown function until now. Rescuing microcephaly ...

Timber and construction, a well-matched couple

2015-07-07
This news release is available in Spanish. Mikel Zubizarreta, a member of the UPV/EHU's IT 781-13 group, highlights the advantages of timber in building works: "Although it is not as tough as other materials used in structures, it is a better insulator, in other words, it is more energy-efficient and less dense so the structure weighs less. On the other hand, timber is a renewable material -trees are planted and grown and forests are a CO2 sink- and is abundant in the Basque Country (nearly 55% of its surface area consists of forests)." Yet timber is used much less ...

Serious adverse events rare in healthy volunteers participating in Phase I drug trials

2015-07-07
PHILADELPHIA - Many people believe that phase I trials with healthy volunteers are very risky and because they pose risks with no benefits, unethical. But how risky are such trials? Less than 1% of 11,000 healthy volunteers who participated in 394 phase I trials for new drugs experienced serious complications, according to a new meta-analysis of participants in non-cancer, phase I medication trials. In addition, none of the volunteers died or suffered persistent disabilities linked to the experimental drugs. In the largest study of its kind, researchers found only 34 (0.31%) ...

C. difficile needs iron, but not too much: Insights into maintaining it 'just right'

2015-07-07
Washington, D.C. - July 6, 2015 - Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron within a range that is healthy for them. Now Theresa D. Ho, PhD, and Craig D. Ellermeier, PhD shed new light on how the pathogen, Clostridium difficile, which is the most common cause of hospital-acquired infectious diarrhea, regulates iron. The research is published online ahead of print July 6 in the Journal of Bacteriology, ...

Study identifies characteristic EEG pattern of high-dose nitrous oxide anesthesia

2015-07-07
While nitrous oxide gas has been used recreationally and medically for more than 200 years - originally for its euphoric and then for its pain relieving and anesthetic properties - the mechanism behind its effects on the brain has been poorly understood. A report from investigators at Massachusetts General Hospital (MGH) finds that the EEG patterns of patients receiving high doses of nitrous oxide differ significantly from those of the same patients when they had received ether-based inhaled anesthetics earlier in the procedures, findings that - along with suggesting how ...

Aspirin may delay growth of asbestos-related cancer

2015-07-07
HONOLULU - Aspirin may inhibit the growth of mesothelioma, an aggressive and deadly asbestos-related cancer, University of Hawai'i Cancer Center researchers have found. The finding could eventually give doctors and patients a potential new tool to fight against this devastating disease, which kills about 3,200 people a year nationwide, and advance knowledge of how to fight other cancers. The study published in Cell Death and Disease showed that aspirin slows down the growth of mesothelioma by blocking the carcinogenic effects of the inflammatory molecule, High-Mobility ...

Engineers give invisibility cloaks a slimmer design

Engineers give invisibility cloaks a slimmer design
2015-07-07
Researchers have developed a new design for a cloaking device that overcomes some of the limitations of existing "invisibility cloaks." In a new study, electrical engineers at the University of California, San Diego have designed a cloaking device that is both thin and does not alter the brightness of light around a hidden object. The technology behind this cloak will have more applications than invisibility, such as concentrating solar energy and increasing signal speed in optical communications. "Invisibility may seem like magic at first, but its underlying concepts ...

Optical 'dog's nose' may hold key to breath analysis

2015-07-07
University of Adelaide researchers are developing a laser system for fast, non-invasive, onsite breath analysis for disease, potentially enabling screening for a range of diseases including diabetes, infections and various cancers in the future. The researchers have developed an instrument they equate to an "optical dog's nose" which uses a special laser to measure the molecular content of a sample of gas. "Rather than sniffing out a variety of smells as a dog would, the laser system uses light to "sense" the range of molecules that are present in the sample," says ...

KUNMING, 7 July 2015 - Increasing amounts of environmentally valuable and protected land are being cleared for rubber plantations that are economically unsustainable, new research suggests. More widespread monitoring is vital to design policy that protects livelihoods and environments. The research was recently published in Global Environmental Change and constitutes a joint effort by scientists at the World Agroforestry Centre (ICRAF) East and Central Asia office, the Chinese Academy of Sciences, the Royal Botanic Garden Edinburgh, the University of Singapore and the ...
