Study: US College Students Advance Little Intellectually After two years, 45 percent show no significant improvement

This is the time of year when millions of American high-school seniors and their parents scramble to complete the process of finding, and getting accepted by, a college to begin the higher education process in September.

But there’s some doubt about how high that level of learning will be.

The title of a new book tells the story. Based on a recent study by sociologists Richard Arum of New York University and Josipa Roska of the University of Virginia, the title is: “Academically Adrift: Limited Learning on College Campuses.”
The professors interviewed 2,300 U.S. college undergraduates and reviewed their academic records.
They concluded that after two years in college, 45 percent of the students showed no significant improvement in key intellectual and creative skills such as critical thinking, complex reasoning, and writing.

University of Virginia professors interviewed 2,300 US college undergraduates and reviewed their academic records. The results of their study appear in, “Academically Adrift: Limited Learning on College Campuses.”
These results come at a time when President Barack Obama, his education department and outside reformers are all saying that the United States had better start producing smarter college graduates if it wants to remain competitive globally.

The study of students’ behavior during those first two years in college may provide a clue as to what’s breaking down.
The researchers found that freshmen and sophomores are more concerned with socializing and communicating with friends than with what used to be called “cracking the books.”
Their “critical thinking” would appear to involve choosing the right pizza joint or bar at which to meet those friends.

“It’s good to lead a monk’s existence [in college],” says Eric Gorski, an Associated Press writer who reported on the study. “Students who study alone and have heavier reading and writing loads do well.”

Unfortunately for U.S. educational achievement, not many monastic types appear to be applying to college these days.

Save our nature, keep our culture

INDONESIA, The incredible nature by magnificent Creator

 

Nature and Adventure Tours

Indonesia is the LAND of ADVENTURE .The archipelago is dotted with volcanoes, covered with thick tropical rainforest and bright green rice fields, and surrounded by coral reefs. All these make the Indonesian archipelago one of the world’s most beautiful places. Four-fifths of the area is occupied by the sea; the major islands are Sumatra, Java, Bali, Lombok, Flores, Sumba, Borneo, Sulawesi, and Papua.

Culture

Indonesia is rich with culture with almost 300 ethnic groups. The diverse ethnic groups, scattered around the islands, offer a wide range of traditional arts including textiles, primitive art, antiques, woodcarving, stonecarving, metalcrafts, and traditional festival. Explore the unique Dayak culture in the heart of Borneo and the Asmat in Papua.

Volcanoes

Most of Indonesia’s highest mountains are volcanoes, except the Mount Carstensz Pyramid 4884 M & Mount Trikora 4.740M in Papua. Some of the world’s most famous volcanoes are : Mt. Kerinci 3.805 M, the highest volcano in South East Asia; Mt. Semeru 3.676 M with its sister peak Mt. Bromo; Mt. Rinjani 3.726 M on Lombok Island.

Wildlife

The archipelago is amazingly rich in animal and plant life: orangutan, sumatran tigers, one horned rhinos, wild ox, elephants, anoa, babi rusa, dugong, Tarsius spectrum – the smallest monkey in the world, Komodo dragon, and the Giant “Leatherback” sea turtle. The spectacular Wilson’s Bird of Paradise can be seen on Batanta Island, Papua.

National Parks

The most expedient way to view plant and animal life is to visit one of Indonesia’s nature reserves. In Ujung Kulon National Park, you may see wild cattle, rusa, leopard, gibbon, and one of the last remaining Javan rhinos. Other national parks which preserve the diversity of the flora and fauna are : Kerinci Seblat National Park (Sumatra), Gede Pangrango National Park (West Java), Bromo Semeru Tengger National Park (East Java), Betung Kerihun National Park (Kalimantan).

Genome Shows Humans More Gorilla like than Thought

Humans and chimps separated from a common ancestor six million years ago, while gorillas split off from that common ancestor four million years before that, confirms a new study, published in Nature.
Sixty scientists worked over five years to sequence the genome of a single female lowland gorilla, the last of the great apes to have its DNA mapped.

According to lead author Aylwyn Scally, of the Trust Genome Campus of the Wellcome Trust Sanger Institute in England, even with that evolutionary distance, humans and gorillas have a lot more in common, genetically, than previously thought.

Kamilah, a 34-year old female lowland gorilla who lives in the San Diego Zoo, is the first gorilla to have her genome sequenced.

Kamilah, a 34-year old female lowland gorilla who lives in the San Diego Zoo, is the first gorilla to have her genome sequenced.

 

“The passage of ancestry across the three genomes changes from position to position,”  Scally says. “Although most of the human genome is indeed closer to chimpanzee on average, there’s a sizable minority, 15 percent is in fact closer to gorilla. And another 15 percent is where chimpanzee and gorilla are closest.”

Ninety-eight percent of human and gorilla genes are identical; humans and chimps share 99 percent of their DNA. Co-author Chris Tyler-Smith, also with the Wellcome Trust Sanger Institute, says it’s those relatively few genes that differ between the species that are of special interest.

Genes tell a story

For example, the study finds that a single gorilla gene associated with enhanced production of keratin – a protein that toughens the apes’ fingernails, skin and especially their knuckle pads – is absent from the human genome.

A group of genes, associated with hearing, tells another story.

“It’s been known for some time that hearing genes in humans have shown accelerated evolution,” Tyler-Smith says, “but what we could see by sequencing the gorilla genome was that this acceleration goes back millions of years. So the implication of that is that this is not because of human language ability, it must be for some broader role that these play.”

The gorilla genome sequencing also identified several genes that cause disease in humans, but not in gorillas. One gene leads to a form of human dementia, a second is associated with heart failure in people.

“If we could understand more about why those variants are so harmful in humans, but not in gorillas, that would have important or useful medical implications,” says Tyler-Smith, who intends to explore the ancestral family tree further, to learn what happened as humans and apes evolved on their separate paths.

He says the gorilla sequence is a template that will help to explain many of those evolutionary mysteries.

Michigan’s Nithin Tumma, 17, wins Intel Science Talent Search

A 17 year old from Fort Gratiot, Michigan, won this year’s Intel Science Talent Search, the oldest and most prestigious science competition for high school students in the United States

“It’s a great honor and it pushes me to do the things I’ve been doing, that I love to do in my research work in science, my passion for science,” Nithin Tumma said.

Tumma won the $100,000 prize for research that could lead to more direct, targeted, effective and less debilitating breast cancer treatments.

During the week-long competition in Washington, D.C., he and his peers defended their work before judges and shared it with the public. President Obama applauded their achievements during a special meeting at the White House.

The president was not their only audience in Washington.

Wendy Hawkins, executive director of the Intel Foundation, which sponsors the event, said it puts a spotlight on science, technology, engineering and mathematics (STEM) education for legislators in Congress.

“We want to influence the influencers, the decision-makers, the people who decide where the money flows to make sure that they understand how critical STEM education is for our future and for these students’ future,” Hawkins said.

The projects entered in the Intel competition contribute serious new scientific data and analysis. Jack Li, 18, from El Segundo, California, developed a new way to deliver an enzyme therapy for phenylketonuria (PKU), a genetic disease that causes mental retardation and seizures.

With the help of mentors at the University of California, Los Angeles, Li designed a microscopic capsule that seals and protects the therapeutic enzyme as it passes through the digestive system.

Jack Li poses with his poster board, which explains his research on a therapy for a rare genetic disease.

“The results were really wonderful,” Li said. “The encapsulated version of the enzyme passed through the stomach and the small intestine unscathed, while the unencapsulated version was completely deactivated.”

A drug company has expressed interest in possibly taking Li’s project toward commercial development.

Another finalist, Marian Bechtel, 17, from Lancaster, Pennsylvania, engineered a new system for detecting buried landmines, an urgent problem in war zones worldwide.

 

“They actually kill or injure someone every 22 minutes.” That’s why, she said, “I looked into seismo-acoustics, which is just a fancy word for using sound waves and ground vibrations at the same time.”

Bechtel’s device is able to scan a field until it finds a resonating sound wave that identifies an object as a likely buried mine and not a rock or other debris.

Finalist Marian Bechtel, from Lancaster, Pennsylvania, demonstrates her prototype landmine detector for judges and the public.

“My statistical tests showed some really impressive results. It turns out that the method is actually very effective,” Bechtel said. “I have yet to do blind testing and there are still a lot of improvements I want to make before I send it out somewhere. So far it’s showing a lot of potential.”

Bechtel hopes to publish her work before she heads off to college in a few months.

While neither Bechtel nor Li won the $100,000 top Intel prize, both were awarded $7,500.

But Li said it’s not about the money, it’s about the science.

“I think the role for us as the next generation of America’s leaders is we need to provoke interest in science among our peers. We need to go out and say, ‘Science is cool. Science is something that is awesome and you should get interested in it.’”

Bechtel agreed, calling science her addiction. “Once you get through it and have those breakthroughs. It’s so amazing. It’s such an amazing feeling. You just keep going back to it. I don’t think that I’ll ever be able to break that addiction to science.”

The Intel Science Talent Search confirmed that an “addiction to science” can be a good thing – and that it is driving a new generation of innovators who are helping to address some of the world’s most pressing challenges.
