(Press-News.org) A group of researchers representing four countries summed up the results of the Supertest, a large-scale study of the academic performance of engineering students in Russia, China, India, and the United States. It is the first study to track the progress of students in computer science and electrical engineering over the course of their studies with regard to their abilities in physics, mathematics, and critical thinking and compare the results among four countries. The article about study in Nature Human Behavior.
The HSE Institute of Education played a key role not only in collecting and analyzing data from Russia, but also in developing uniform assessment tools in mathematics and physics for all countries. The Institute conducted a full range of psychometric studies in addition to substantiating the quality of the measurements and the comparability of results across different countries.
The Supertest was initiated by Stanford University, HSE University Moscow, the Educational Testing Service (ETS), and partner universities in China and India. The study authors include Prashant Loyalka, an Associate Professor at Stanford University and a leading researcher at the HSE International Laboratory for Evaluating Practices and Innovations in Education; Igor Chirikov a senior researcher at the Center for Studies in Higher Education at UC Berkeley and an affiliated researcher of the HSE Institute of Education; and Elena Kardanova and Denis Federyakin , leading researchers at the Centre for Psychometrics and Measurements in Education at the HSE.
More than 30,000 undergraduate students participated in the study. The researchers collected a sample of students from elite and large universities, roughly equal in number for each country. In Russia, the sample included students from six Project 5-100 universities and 28 other universities. Their skill development was measured three times: upon entering university, at the end of their second year, and at the end of their studies.
The task of the specialists of the HSE Centre for Psychometrics and Measurements in Education was to develop tests that had questions that would be neutral for students of different countries and would yield adequately comparable results across different countries. 'Over the course of analyzing the test results, we have proven that we were able to achieve both tasks,' said Centre Director Elena Kardanova. 'Testing in different countries was conducted in accordance with the same rules, with the assistance of specially trained examiners. All students were offered the same incentives to participate. We additionally tested the sensitivity of the results to possible differences in student motivation.'
The Supertest showed that at the start of their studies, Russian students perform lower than Chinese students in mathematics and physics, but higher than students from India in mathematics. After two years of study, the gap between Russian and Chinese students narrows, while Indian students catch up with Russian students in mathematics.
One finding of the study that is cause for concern relates to engineering students' critical thinking skills. Initially, upon entering university, Russian engineering students outperform Indian students while performing lower than Chinese students. In terms of developing these skills over the course of their studies, students of all three countries perform lower than students in the United States. 'We found that, as the students progress in their studies, their critical thinking skills remain approximately the same in Russia and India, but significantly decrease in China. On the contrary, American students show improvement,' said Igor Chirikov. This is a serious problem, the researchers note, because technologies change rapidly, and in order to be able to master new ones, you need not only a firm grasp of the subject area, but, above all, skills of the 21st century.
Another unexpected result was the gradual decline of academic skills among engineering students in China. 'Students at Chinese universities have an extremely high level of skills upon enrollment, but over the course of their university studies this level decreases: this applies to physics, mathematics, and critical thinking. We observe this at both elite and large universities, albeit to different extents,' said Igor Chirikov. 'A possible explanation lies in the way undergraduate education is organized in China, where institutions put emphasis on lectures, and instructors are not as demanding as in Russia and India. As a result, students have less motivation to learn and are not held accountable for developing skills.'
The results of the Supertest provide insight into how graduates perform in the globally competitive market of future computer science and electronic engineering professionals. Each represented country is renowned for its engineering expertise, and it is the Chinese, American, Russian and Indian specialists who migrate to different countries that largely determine the technological progress around the world. The balance of power in this sphere of education can play a decisive role in who will win the technology race tomorrow.
March 1, 2021 - Benign bone tumors may be present in nearly 20 percent of healthy children, based on a review of historical radiographs in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
Although that may sound frightening, non-ossifying fibromas and other common benign bone tumors in symptom-free children are harmless and may resolve over time, reports the new study by Christopher D. Collier, MD, of Indiana University School of Medicine and colleagues. "These findings provide unique evidence to answer many commonly encountered questions when counseling patients and their families on benign bone tumors," the researchers write.
Study offers reassurance that benign ...
Blocking cell receptors for glucagon, the counter-hormone to insulin, cured mouse models of diabetes by converting glucagon-producing cells into insulin producers instead, a team led by UT Southwestern reports in a new study. The END ...
Boston, MA--Most pregnant women and mothers of children younger than 18 years old say they would receive a COVID-19 vaccine and vaccinate their children, according to a survey conducted by researchers at Harvard T.H. Chan School of Public Health. The research indicated that vaccine acceptance was highest in India, the Philippines, and all sampled countries in Latin America, and it was lowest in Russia, the U.S., and Australia.
The results will be published online on March 1, 2021 in the European Journal of Epidemiology.
Vaccines for COVID-19 are being distributed around the world, but until ...
SILVER SPRING, Md. - A recent preclinical study by U.S. Military HIV Research Program (MHRP) researchers showed that an experimental therapy combining a TLR7 agonist and two broadly neutralizing antibodies delayed viral rebound in SHIV-infected macaques after antiretroviral therapy (ART) interruption.
The experimental combination therapy consisted of TLR7 agonist GS-986 and two broadly neutralizing antibodies (bnAbs), N6-LS and PGT121, targeting different regions of the HIV envelope. The rhesus macaques were initiated on viral suppressive antiretroviral therapy 14 days post infection, a timespan from infection to treatment which mirrors what is feasible in acute HIV infection. Researchers then administered the experimental combination ...
NEW YORK, NY (March 1, 2021)--By harnessing the immune system against cancer, immunotherapies have revolutionized the way some types of cancer are treated. But most patients--across cancer types--do not respond, and in most cases, scientists are at a loss as to why.
Researchers at Columbia and MIT have created a new technique that can uncover nearly all of the tricks cancer cells use to evade immunotherapies, which could lead to the development of more effective treatments.
The researchers tested their new technique with cancer cells and matching immune cells from melanoma patients and identified previously unknown resistance mechanisms to immune checkpoint ...
Black Americans have a high level of vaccine hesitancy and mistrust of COVID-19 vaccines, including among Black health care workers, according to a new RAND Corporation survey.
Those who expressed vaccine hesitancy also showed high levels of overall mistrust in the vaccine, concerns about potential harm and side effects, and lack of confidence in vaccine effectiveness and safety.
Participants in the RAND survey reported higher trust in COVID-19 information from health care providers and public health officials than from elected local and federal officials.
The findings are based on a survey ...
Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs. The scaffolding material -- usually a biodegradable polymer structure -- is supplied with cells and the cells, if supplied with the right nutrients, then develop into tissue as the underlying scaffold biodegrades. But this model ignores the extraordinarily dynamic morphological processes that underlie the natural development of tissues.
Now, researchers at the END ...
A team of international researchers led by a Florida State University assistant professor has analyzed reams of data from the Neolithic to Late Roman period looking at migration patterns across the Mediterranean and found that despite evidence of cultural connections, there's little evidence of massive migration across the region.
"Because of the prevailing scholarly attitude of the 'connected' Mediterranean -- one with high degrees of mobility and migration that drive the archaeological patterns we see -- we'd imagined we'd see comparatively high levels of migration reflected in the strontium isotope data," said Thomas Leppard, assistant professor of anthropology at Florida State. "That instead ...
Invasive alien species, defined as animals and plants that breed and disperse in a landscape beyond their native range, have negative environmental, social, and economic impacts. One example among many is the forage grass genus Brachiaria, originally African and introduced to Brazil to form cattle pasture. It has become a major threat to the survival of native species and biodiversity at several spatial scales.
Complete eradication of invasive species is often impracticable. Attempts to do so have had undesirable consequences and even been damaging because merely withdrawing an invasive ...
Too much activity in the hippocampus may cause navigation impairments seen in aging adults, according to new research published in JNeurosci.
Spatial navigation is one of the cognitive abilities that declines sharply in old age. Older adults often have difficulty navigating new environments and will choose to stick with familiar ones. Plus, key regions in the brain's navigation circuit are some of the first affected by Alzheimer's disease. In a recent study, Diersch et al. examined the neural mechanism behind this decline in spatial learning.
In the study, younger ...
