Chinese Researchers Are Outperforming Americans in Science

Posted on by

For decades, China’s growth was driven by shifting workers from agriculture to manufacturing. As the country started to approach the so-called Lewis turning point, when such shifts no longer raise overall productivity, the government made an increasingly concerted effort to build the scientific base to provide another vector for growth. The results of those efforts are showing up in both the rankings of Chinese universities (11 of the top 100 globally) and in scholarly output.

The unbelievable benefits of the USG CIO’s bottomless bucket of bandwidth

Posted on by

Our private cloud configuration allows our CIOs the luxury of not focusing on bandwidth because it always works. We’ve been able to layer value-added services on top of it — more traditional services like bandwidth as a service, software as a service, backup as a service, and virtual data centers as a service. Our institutions now can focus on students and the value they add to our schools, not on IT as a standalone commodity.

Adjusting GPAs: A Statistician’s Effort to Tackle Grade Inflation

Posted on by

A recent analysis of 200 colleges and universities published in the Teachers College Record found that 43 percent of all letter grades awarded in 2008 were A’s, compared to 16 percent in 1960. And Harvard’s student paper recently reported that the median grade awarded to undergraduates at the elite school is now an A-.

“That allowed me to look directly at the influence of course grades on student evaluations,” Johnson said. “As you might expect, the effect of either expected course grade or received course grade is very powerful in student evaluations of teaching. If a student was getting a C in a course, he or she was very unlikely to rate the instructor highly. If they were getting an A in the course, they’re more likely to rate the instructor highly. I think this provides quantitative evidence for something most instructors know: If they grade easier, they will tend to get better course evaluations.”

10% of Amplify Tablets Broke in Their First Month, One North Carolina School District Reports

Posted on by

This tablet was always intended to go into schools, and that is why it was supposed to have been built with a layer of Gorilla Glass over the screen. This was in the contract that GCS signed, and it was also mentioned prominently in the early news coverage of this tablet. According to the school district, none of the Amplify tablets that they bought had that protective layer, which might help explain why so many tablets broke.

Or to put it another way, the absence of Gorilla Glass is a sign that someone cut corners on the build quality for this production run. Given that there were also complaints about misfitted cases and defective power supplies,  I am not terribly surprised.

“It suggests, falsely, that ideas are property and that building on others’ ideas always requires permission,” Stoltz says. “The overriding message of this curriculum is that students’ time should be consumed not in creating but in worrying about their impact on corporate profits.”

The Post-Lecture Classroom: How Will Students Fare?

Posted on by

A three-year study examining student performance in a “flipped classroom” — a class in which students watch short lecture videos at home and work on activities during class time — has found statistically significant gains in student performance in “flipped” settings and significant student preference for “flipped” methods.

The STEM Crisis Is a Myth

Posted on by

To parse the simultaneous claims of both a shortage and a surplus of STEM workers, we’ll need to delve into the data behind the debate, how it got going more than a half century ago, and the societal, economic, and nationalistic biases that have perpetuated it. And what that dissection reveals is that there is indeed a STEM crisis—just not the one everyone’s been talking about. The real STEM crisis is one of literacy: the fact that today’s students are not receiving a solid grounding in science, math, and engineering.

Providers of Free MOOC’s Now Charge Employers for Access to Student Data

Posted on by

On Tuesday, Coursera, which works with high-profile colleges to provide massive open online courses, or MOOC’s, announced its employee-matching service, called Coursera Career Services. Some high-profile tech companies have already signed up—including Facebook and Twitter, according to a post on Coursera’s blog, though officials would not disclose how much employers pay for the service. Only students who opt into the service will be included in the system that participating employers see, a detail stressed in an e-mail message that Coursera sent to its nearly two million past or present students on Tuesday.
