Constructivizing STEM

by Robert Pondiscio
February 22nd, 2012

The following guest post is by Katharine Beals, who blogs about education at Out in Left Field, where this post also appears.  — rp.

It’s hard not to detect a certain worry among those who write STEM articles for Education Week that the drive to educate students for careers in Science, Technology, Engineering, and Mathematics might include a drive to increase core scientific and mathematical content at the expense of things that Constructivists hold dear. Things, for example, like “model building,” “data analysis,” and “communicating findings.”

These are what Jean Moon and Susan Rundell Singer, in their backpage Edweek Commentary on Bringing STEM into Focus, want to be sure schools are focusing on:

Re-visioning school science around science and engineering practices, such as model-building, data analysis, and evidence-based reasoning, is a transformative step, a step found in the NRC report, which is critical to STEM learners and teachers, both K-12 and postsecondary. It puts forward the message that knowledge-building practices found under the STEM umbrella are practices frequently held in common by STEM professionals across the disciplines as they investigate, model, communicate, and explain the natural and designed world.

Not that this is all that Moon and Singer care about. They also care about big ideas, which they divide into two categories: “crosscutting concepts (major ideas that cut across disciplines)”, and “disciplinary core ideas (ideas with major explanatory power across science and engineering disciplines.” The former include “scale, proportion, and “quantity or the use of patterns;” the authors don’t cite any examples of the latter.

Besides “practices” and ”ideas,” the authors mention “strategies” and “tools” (again, without specific examples). What they don’t mention is underlying content, except to say:

Lest some believe this is setting up another false dichotomy in science or mathematics education between content and process, let us quickly add a strong evidentiary note: Epistemic practices and the learning and knowledge produced through such practices as building models, arguing from evidence, and communicating findings increase the likelihood that students will learn the ideas of science or engineering and mathematics at a deeper, more enduring level than otherwise would be the case. Research evidence consistently supports this assertion.

I’m curious what “research evidence” means, but I gather that it doesn’t include the research evidence that cognitive scientist Dan Willingham cites in support of the idea that students aren’t little scientists and need a foundation of years of core knowledge before being ready to function as actual scientists.

In promoting their ideas as “transformative,” the authors are overlooking the fact that the kinds of constructivist practices they desire are already standard in many schools (particularly those held up as models for others). If they want to promote something truly transformative for STEM, they should instead be advocating a reinstatement of the years of solid, content-based instruction in math and science that many of our K12 schools used to offer (and that one still finds in schools in most developed countries around the world).

Core Knowledge Quiz: Volcano Edition

by Robert Pondiscio
April 20th, 2010

Stranded in the airport waiting for a flight to or from Europe?  Pass the time and entertain fellow passengers with this Core Knowledge Quiz about volcanos.  Bonus points if you can correctly pronounce Eyjafjallajökull.

  1. What is the difference between lava and magma? 
  2. Geologists generally identify four types of volcano: cinder cones, composite volcanoes, shield volcanoes, and lava domes.  The Hawaiian Islands are a chain of which type of volcano? 
  3. A massive eruption of this volcano on 1883 killed over 36,000 people; ash from the explosion may have caused a worldwide drop in temperature. 
  4. Nearly 75% of the world’s active and dormant volcanoes occur in a zone called the “Ring of Fire” around which ocean? 
  5. Which country has the most active volcanoes? 
  6. The world’s tallest volcano is in the United States.  What is it? 
  7.  The word volcano comes from an island off the coast of Sicily. During the Roman Empire, it was thought that Vulcano was the home of which Roman god?
  8. How many active volcanoes are on Earth?  Less than 500?  500 to 1000?  1000 to 2000?  1000 to 2000. Or over 2000? 
  9. The expression “to blow his top” is thought to come from volcanoes.  When this U.S. volcano blew its top in 1980, it lost 1,300 feet from its summit. 
  10. Last week’s eruption of Eyjafjallajökull in Iceland is an example of a “Plinian” eruption–when a volcano spews a massive column of ash and gas into the stratosphere.  The name comes from the Roman statesman Pliny the Younger, who wrote a detailed description of the eruption of which famous volcano?

Less School, Higher Scores in Finland

by Robert Pondiscio
April 9th, 2010

Children in Finland spend fewer hours in school than any other country in the developed world so how do they consistently turn in top international scores in reading, science and math?  A BBC report focuses on the relaxed atmosphere of the nation’s schools, lack of political interference, as well as the country’s approach to schooling.

“The Finnish philosophy with education is that everyone has something to contribute and those who struggle in certain subjects should not be left behind.  A tactic used in virtually every lesson is the provision of an additional teacher who helps those who struggle in a particular subject. But the pupils are all kept in the same classroom, regardless of their ability in that particular subject.”

The report makes much of the contributions of Finnish home life to student achievement.  “There is a culture of reading with the kids at home and families have regular contact with their children’s teachers,” notes the BBC’s Tom Burridge, who also points out that teaching is a prestigious career in Finland. “Teachers are highly valued and teaching standards are high,” he says.

Education Minister Henna Virkkunen is now looking to boost the performance of Finland’s brightest pupils.  ”The Finnish system supports very much those pupils who have learning difficulties but we have to pay more attention also to those pupils who are very talented. Now we have started a pilot project about how to support those pupils who are very gifted in certain areas,” she says.

Lies, Damned Lies and Science

by Robert Pondiscio
January 8th, 2010

Let’s face it, writes Stephen Battersby at the New Scientist, science is boring.  Discoveries of new planets, medical advances and potential environmental disasters leave the impression that science is exciting and cutting edge.  Not so. 

It is now time to come clean. This glittering depiction of the quest for knowledge is… well, perhaps not an outright lie, but certainly a highly edited version of the truth. Science is not a whirlwind dance of excitement, illuminated by the brilliant strobe light of insight. It is a long, plodding journey through a dim maze of dead ends. It is painstaking data collection followed by repetitious calculation. It is revision, confusion, frustration, bureaucracy and bad coffee.

Science may be boring, but Batterby’s essay is a hoot.  Especially his description of his own inglorious research career, which involved months of sifting data from a telescope and finding…nothing.

I tip my hat, though, to New Scientist‘s San Francisco bureau chief, who spent nearly three years watching mice sniff each other in a room dimly lit by a red bulb. “It achieved little,” he confesses, “apart from making my clothes smell of mouse urine.” And the office prize for research ennui has to go to the editor of NewScientist.com. “I once spent four weeks essentially turning one screw backwards and forwards,” he says. “It was about that time that I decided I didn’t want to be a working scientist.”

Let’s keep this to ourselves and not mention it to the children, shall we?  After all, our economy and national security are at stake.

Update:  Not bored yet?  Joanne Jacobs asks “Do children need to be bored?”  Insightful Willingham response in the comments.

4th Grade Science, 3rd Rate Answers

by Robert Pondiscio
March 16th, 2009

How long does it take the Earth to revolve around the Sun? Did the earliest humans and dinosaurs live at the same time?  What percent of the Earth’s surface is covered with water?  If you don’t know the answers to all three questions (1 year, no, and about 70%) then you have company.  Lots of company.  Only one out of five American adults know the answer to all three questions, according to a survey commissioned by the California Academy of Sciences.

Despite the low grasp of science knowledge, about 4 in 5 adults say science education is “absolutely essential” or “very important” to the U.S. healthcare system (86%), the U.S. global reputation (79%), and the U.S. economy (77%).  They would know. 

Take the quiz yourself at the California Academy of Science website.

Teaching For High Expectations

by Robert Pondiscio
February 23rd, 2009

Why go to high school when you can go to school high?  In an anonymous piece on the Radio Free Exile website “Bob Smith,” a 59-year old former science teacher, describes how years of getting high while planning his lessons provided him with “insights into the educational process” and other “truly important things about teaching.”  Take, for example, his solution to the problem of how to explain the concept of density to middle schoolers.

Suddenly, a flash of the legendary insight: I just won’t teach density. Not at all. Never again. Now, as first year teachers learn, you teach what they tell you to teach. But as some teachers soon learn, you can teach what you like if everything you do works. I had been pretty successful in all the other areas of science I was teaching, and I realized that I would be doing everyone a favor if I unilaterally declared that piece of the pie dispensable, which I did, and I’m sure that no one ever missed it.

Believing he was at his most inventive and insightful while stoned, Saturdays became the day when Smith ruminated on his teaching, wrote curriculum, made plans, and got high.  “I sometimes laugh to myself when something I’ve designed has gone over well with the students. They would be amazed at the conditions under which the ideas were hatched,” Smith writes.

In fact, I should go so far as to confess that when discussing drugs with students – a requirement of science curriculum in those grades – I have presented to the students the positives as well as the negatives of marijuana use, including ‘reports’ that people often feel more creative and insightful, and that people smoke it because it’s fun. This is an important part of the drug education piece that is always omitted: telling kids why people use drugs.

If you’re concerned about having a teacher like “Bob Smith” giving his fair and balanced view of recreational drug use to kids, fear not.  He’s no longer teaching middle school.  He’s now an ed school professor. 

Higher ed, indeed.

A Gesture Gap?

by Robert Pondiscio
February 13th, 2009

The researchers studied 50 families from diverse economic backgrounds. They recorded video of children with their parent, or primary caregiver, for 90-minute sessions, during ordinary home activities.  Fourteen-month-old children from high-income, well-educated families used gesture to convey an average of 24 different meanings during the 90-minute session. Meanwhile, children from lower-income families conveyed only 13. 

Their study, in the journal Science, suggests gestures could play an indirect role in word learning by eliciting speech from parents.  “For example, in response to her child’s point at the doll, mother might say, ‘Yes, that’s a doll,’ thus providing a word for the object that is the focus of the child’s attention,” they wrote.

TIMSS: Solid, Spectacular, Troubling or Dismal?

by Robert Pondiscio
December 10th, 2008

Results of the 2007 Trends in International Mathematics and Science Study (TIMSS) were released Tuesday, and the data proves to be a bit of an educational Rorschach Test.  The New York Times sees “solid achievement gains” in math by U.S. 4th and 8th graders, and “spectacular progress” by students in Minnesota and Massachsetts, while science performance remained flat nationwide.  “The results showed that several Asian countries continued to outperform the United States greatly in science and math,” notes the Times, “subjects that are crucial to economic competitiveness and research.”

USA Today’s Greg Toppo sees American students “consistently better than average,” but notes that “if there were a math-and-science Olympics for elementary and middle schoolers…the USA never quite makes it to the medal podium.”

At Flypaper, the Fordham Foundation finds reasons to be cheerful.  “American students have made steady gains in mathematics performance over the past decade. This progress was especially noteworthy at the eighth grade level, where the U.S. made gains since 1995 that were at least as strong as all of our major economic competitors.”  Diane Ravitch disagrees however that 8th grade gains are “noteworthy.”

The gains posted by 8th graders are certainly not a vindication of No Child Left Behind’s testing regime. Eighth-graders registered a 12-point gain in math from 1995-2003, before the imposition of NCLB testing. They posted a 4-point gain from 2003-2007. The students who were tested by TIMSS in 2007 had been subject to NCLB annual tests in every year from third grade onward, yet their scores did not show a dramatic improvement. If anything, the gains were no greater (and possibly smaller) than those registered pre-NCLB.

Democratic Congressman George Miller sees “significant gains” in 4th grade math, but tells the Washington Post it’s “troubling that our students are still behind their international peers in both math and science.”  Tom Loveless of the Brookings Institution, tells USA Today that the new TIMSS results belie complaints that U.S. students are lagging behind the rest of the world in math. “It’s just not true,” he says. “It hasn’t been true for a long time.”  Meanwhile the National Science Teachers Association pronounces itself “discouraged” by the results, noting science scores for minority students are “dismal.”  Many districts simply do not value science education, says a statement released by the NSTA Tuesday. ”Science is being eliminated from many K-6 classrooms.”

Science for Girls

by Robert Pondiscio
November 29th, 2008

England’s new Schools Minister thinks single-sex science classes would get more girls to choose careers in science and engineering.  “Girls do much better in science in single-sex classes. Sarah McCarthy-Fry tells The Independent.  ”They sometimes feel intimidated in mixed-sex classes with the boys hogging the limelight and putting their hands up to answer all the questions.” Mrs Tuck said more people were aware girls learnt differently from boys due to “neurological differences” in the developments of their brains.

“Oh Jeebus, what now? High School Musical-branded Bunsen burners?” groans one wag over at the blog Liberal Conspiracy. “The idea of making the sciences more ‘girl-friendly’ in order to attract more women is not only a crock of s— but, if followed through as a policy objective, yet another nail in the coffin of science education in the UK.”

A slightly more measured take can be found over at Richard Whitmire’s blog, Why Boys Fail.

Unacceptable is the New “Adequate”

by Robert Pondiscio
August 7th, 2008

Asked under oath in a deposition if science is ”part of an adequate education” in the state of Georgia, Joanne Leonard said “I think you can do without science.”  What about social studies? Is that part of a child’s ”adequate” education?  “I would want them exposed to social studies,” Leonard said, ”but I think they can succeed in the world without social studies, and that is my opinion, my personal opinion.”

Ms. Leonard’s deposition was taken in a lawsuit brought by rural Georgia schools, who say the state isn’t giving them enough money to provide the “adequate education” required under law.  Much of the case involves defining “adequate”  And who is Joanne Leonard? Only the state Department of Education’s Director of Accountability.

I’m trying to think of what the appropriate response to this should be from Georgians, but I can’t think of anything that doesn’t involve pitchforks and torches.  But I can think of something else Georgia can do without.
