Apparently science education in the U.S. lags behind other nations. Gee. I wonder why. Most likely because we have a very anti science group of folks ruling the halls of power in D.C. Not that I'm bitter...
Really, though, the article is not good. First off is for the obvious: we are not doing science education very well here, okay, but there are no solutions presented.
The article itself, however, is problematic. It starts with the comment that "faults science curricula for assuming children are simplistic thinkers." While this is true, to a certain extent, the statement should really be turned around. Science curricula actually assume that the teachers are not sufficiently well educated in sciences to teach it well. This sounds somewhat nasty, but keep in mind that in many cases the first science education a child receives is from a teacher whose major was education (possibly with an emphasis) and who is qualified to teach several different subjects. There is less specializaiton in elementary and middle school, and by the time students reach high school they already have been taught to have science presented in a specific way. There are educators who are working to change this, but it is not so simple a process as just changing the science curricula. Guidelines provided by science groups like NAS (national acadamy of sciences) are content (e.g. a student should know the parts and functions of a cell) not methods and many different curricula could get the info across.
Nevermind that, though, because it isn't new, and scientists, in particular, are aware of it, if only through the poor understanding presented by friends, family, politicians, press, etc. The problem with the article is related to the prase "simplistic thinkers" opens the door for all of the psuedo science crackpots to push (including the Creationist/ID wackjobs). Science can become very complicated, very quickly, and psuedo-science advocates take advantage of that. The vast amount of accumulated scientific knowledge becomes a double edged sword because no one person can be sufficiently advanced to be an expert in every one of the things that are covered in science from K-12. Because of that the psuedo-sci supporters can often win "debates," even if they out and out lie.
Since it is a popular front, take, for example, evolution. Evolution is taught in biology, but the evidence for evolution comes from genetics, geology, species diversity, human history, the fossil record, anatomy, and biochemistry, basically many fields covering all of the physical sciences. Most biology teachers understand very basic notions related to some of the genetics, some of the fossil record, some of the diversity, the radio dating aspects of geology and anatomical aspects like vestigal appendiges (note that most bio majors will not have a significantly more advanced understanding). An anti-evolution puppet would not trash all of the science, but would pick one or two fairly specific aspects to take apart, typically ones that are not directly related to biology. A sufficiently knowledgeable scientist would decimate such attacks, but few and far between is the elementary/middle/high school teacher that could do so.
Science education is lacking in the U.S., to be sure, but the directions offered to "fix" science education are vague, misleading, and open to attack from those who seek to make science what they want it to be rather than what it is. The key to improving science education is not to focus on what science has discovered, but rather what science is, and using discoveries, theories, and changes in perception through history as examples.
