Preparing Computer Science Students for Jobs

in, Preparing Students for Jobs, Michael Mitzenmacher, a computer science professor at Harvard asks past students to comment on how well school prepared them for work.

In a recent “discussion” on another blog, I repeatedly heard the refrain that we ivory-tower pie-in-the-sky university computer science professor types just aren’t preparing students suitably for “real-world” employment. Personally, I think that’s just BS. However, I realize I may have a fairly biased viewpoint. I teach at Harvard, and, if I may say so, our students are generally quite good and do well in the job market. Having spent some time in industry, and, if I may so so, being perhaps more interested than the average theorist about practical issues, I attempt to add “real-world” aspects to my classes, like programming assignments in my undergraduate theory course.

Please tell me, in your experience, did your education prepare you for your life after in the real world.

50 Species of Diatoms

Photo of diatoms by Randolph Femmer (sadly the government deleted the site, breaking the link, so I removed it).

A photomicrograph depicting the siliceous frustules of fifty species of diatoms arranged within a circular shape. The image has been inverted to white on black to bring out details. Diatoms form the base of many marine and aquatic foodchains and upon death, their glassy frustules form sediments known as diatomaceous earth.

$500,000 for Innovation in Engineering Education

The 2008 Bernard M. Gordon Prize, recognizing innovation in engineering and technology education goes to Lawrence Carlson and Jacquelyn Sullivan, University of Colorado at Boulder. CU-Boulder Faculty To Receive $500,000 Prize For Innovation In Engineering Education

The $500,000 award honors them as founders of the Integrated Teaching and Learning Program at CU-Boulder, which infuses hands-on learning throughout K-16 engineering education to motivate and prepare tomorrow’s engineering leaders.
…
The laboratory is essential to the ITL Program’s undergraduate curriculum in which engineering students from all departments, beginning in their first year, can take design courses in which small teams develop products to solve real problems. Leadership qualities emerge as teams call upon each member’s strengths to create and manage an engineering project from start to finish, and all teams showcase their creations in the semi-annual Design Expo. The first-year design course has contributed to significantly higher retention for all students across the engineering college.

A second element of the program’s curriculum is the extensive development and implementation of K-12 engineering education. About 1,700 students in grades three through 12 experience the excitement of hands-on engineering in weekly classes taught by engineering graduate students — helping them realize that engineering is about making a difference in the world. The classes are a partnership between the ITL Program and six neighborhood public schools in Lafayette as well as the Denver School of Science and Technology.

5 Dangerous Things You Should Let Your Kids do

5 dangerous things you should let your kids do

Gever Tulley, founder of the Tinkering School, talks about our new wave of overprotected kids — and spells out 5 (and really, he’s got 6) dangerous things you should let your kids do. Allowing kids the freedom to explore, he says, will make them stronger and smarter and actually safer.

It is not necessarily the safest thing to try and eliminate all risks. Kids can learn to be safer when they work on not entirely safe things with parents or others that can teach them how to do so safely. And they learn to interact with the world around them and think like a scientist.

Science and Engineering Education Collaboration in Virginia

Two new schools to focus on technology

Two new schools focused on career, technology and engineering for high school and college students will open in Newport News and Suffolk. But while the Suffolk school will have a home in the Pruden Center for Industry, the other will look more like a network, reaching out from a base at the New Horizons Regional Education Center into six school districts, two colleges, at least one government agency and several area businesses.
…
The Newport News academy is aimed at high school students and will focus on electrical and mechanical engineering, Johnson said. Students will follow the curriculum requirements for an associate of arts degree available at academy partner Thomas Nelson Community College, which can lead to a bachelor’s degree at another partner, Old Dominion University. Russo said emphasis will include robotics, modeling and simulation technology and engineering.

Instead of housing the school at New Horizons or Thomas Nelson, the academy’s classes will be taught in public high schools in Gloucester County, Newport News, Hampton, York County, Poquoson and Williamsburg-James City County, at New Horizons and at Thomas Nelson. Additional courses will be available online.

Mapping Where Brains Store Similar Information

CMU finds human brains similarly organized

Based on how one person thinks about a hammer, a computer can identify when another person also is thinking about a hammer. It also can differentiate between items in the same category of tools, be it a hammer or screwdriver.
…
The study makes two important scientific advances: “[T]here is an identifiable neural pattern associated with perception and contemplation of individual objects, and that part of the pattern is shared” by people.

The study reveals that patterns of thought extend into different regions of the brain, reflecting its complexity. It proves that a simple image can invoke thoughts in various regions of the brain, including how to use the object and experiences one has had with the object.

The study also helps to explain how the brain organizes thoughts, and the commonality of that process. “I want a complete mapping of brain states and thoughts,” Dr. Just said. “We’re taking tiny baby steps, but anything we can think about is represented in the brain.”

Lemon Tree in Japan Bears Eleven Kinds of Fruit!

A 71-year-old farmer has found a unique solution to Japan’s chronic shortage of space: grow 11 different kinds of fruit on a single tree! Manabu Fukushima of Onga, Fukuoka prefecture, combines natural horticultural skill, a lot of time and the kindness of neighbors to create one of the oddest trees you’ll ever see: a very confused Lemon tree that bears ten other citrus fruits – and Fukushima isn’t done yet!
…
“Next year I want to increase the varieties,” according to the smiling farmer, and he’ll likely be true to his words based on previous success. In fact, the only thing stopping him may be a lack of suitable citrus fruit “scions” for him to graft.

Evolution is Fundamental to Science

Evolution is absolutely fundamental to scientific thinking. Any country, or part of a country (or those wishing to lead a country) that teaches evolution as though it is some alternative way of looking at the facts (that can be compared to creationism/intelligent design, as science, for example) is an embarrassment. Unfortunately the United States is home to far too much of this thinking – which explains why scientific literacy is so low. Luckily there are also plenty in the USA that understand science. The National Academy of Science has published, Science, Evolution, and Creationism, in which a

group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including “intelligent design.” The book explores the many fascinating inquiries being pursued that put the science of evolution to work in preventing and treating human disease, developing new agricultural products, and fostering industrial innovations. The book also presents the scientific and legal reasons for not teaching creationist ideas in public school science classes.

The scientific theory of evolution still has details that can be debated – which is what the scientists should and will do (seeking out evidence to support such details). The idea that people today can question evolution is beyond amazing to me. It is much easier to understand some people thinking you would sail off the edge of the earth 500 years ago than anyone in the USA thinking there is any serious debate about evolution (there are parts of the world where the educational system does not give everyone a chance to see the available evidence, so I can forgive some in the world for being ignorant – not having been exposed to the evidence). And I guess there are parts of the USA educational system that are nearly so poor also where a gullible student could not see the truth. But in the USA the evidence is easily at hand – you have to intentionally remain ignorant to somehow not understand the truth of evolution.

What Everyone Should Learn:

Dr. Vincent Cerf: “I would want people to really understand the theory of evolution and the origin of species. The power of cumulative, adaptive change in the genome, over the course of billions of years and changing conditions, is hard for many people to fully appreciate.”

Robot Fly

Tinker, Tailor, Robot, Fly

Designing an automated fly implied having the ability to make lightweight, miniature working parts, a process that Wood says took up the bulk of his doctoral study, because of the lack of any previous research on which to draw. “For years, the thrust of our work was ‘How do we do this?'” says Wood. “There was no existing fabrication paradigm, given the scale we were operating on, the speed we wanted to operate with, and things like cost, turnaround, and robustness.” His research group developed and fabricated a laser carving system that could meticulously cut, shape, and bend sheets of carbon fiber and polymer – both strong but lightweight materials – into the necessary microparts.

And how to power those wings to beat 120 times per second? To keep this 60-milligram robot (the weight of a few grains of rice) with a 3-centimeter wingspan to a minimal size and weight, Wood says, you can’t simply use a shrunken version of the heavy DC (direct current) motors used in most robots. So he and his team settled on a simple actuator: in this case, a layered composite that bends when electricity is applied, thereby powering a micro-scale gearbox hooked up to the wings. Wood says the actuator works even better than its biological inspiration. The power density – a measure of power output as a function of mass – of a fly’s wing muscles is around 80 watts per kilogram; Wood’s wing design produces more than 400 watts per kilogram.

The first takeoff occurred late one evening last March, as Wood worked alone in his office, his colleagues gone for the evening. As the fly rose, Wood jumped up in celebration, quickly verified that his camera had captured the flight, and let out a sigh of relief.
