How well are American schools teaching science?

4 Comments

Stuart Schneiderman links to this post.

Excerpt:

The results are in and America’s elementary, middle and high school students are stumped by science.

The National Center for Education Statistics released the findings of their National Assessment of Educational Progress science exam this week and it doesn’t bode well for the state of STEM (Science, Technology, Engineering and Mathematics) education. While the majority of students at the fourth, eighth and twelfth grade levels could successfully complete straightforward hands-on or computer-based tasks and arrive at the correct conclusions, once additional variables or more complex calculations were introduced, their performance declined dramatically.

For example, 75% of high school seniors could successfully use test strips to test water samples for the levels of four pollutants, record the data and interpret whether the results exceeded EPA standards, but only 25% of students were able to design and conduct an investigation using a simulated calorimeter and related patterns in temperature changes in two different metals to determine which metal has the higher specific heat capacity. Results were the same at the lower grade levels, where only 24% and 35% of eighth and fourth graders respectively were able to handle the more difficult experiments. Students also had difficulty in explaining how they arrived at a correct conclusion, with only 27% of twelfth graders able to both select a correct answer and explain why they did so in one section of the test. And in another section, only 11% were able to make a final recommendation that was supported by the data they had worked with in the experiment.

[…]Currently, only about a third of bachelor’s degrees awarded in the US are in the STEM fields – by contrast, over half of Chinese and Japanese college students are specializing in STEM subjects. The economic and career benefits of STEM education are well-documented. STEM occupations are forecasted to grow faster than non-STEM occupations through to 2020. Over the course of the recession, unemployment in STEM fields has been almost half that of non-STEM fields. And STEM professionals earn, on average, approximately 26% more than non-STEM counterparts.

[…]If there’s a bright spot in the NAEP report, it’s the fact that female students are matching or exceeding the performance of their male peers in both hands-on and interactive tasks.

I always encourage Christians to go into STEM fields, especially men who have a Biblical mandate to provide for their families, if they have one. Women can be more flexible in what they study. Men are obligated to go for the bucks.

Regarding that comment in bold that I highlighted, Stuart writes:

Schools are not teaching advanced scientific problem-solving and reasoning, but they have achieved gender parity.

Is this an accidental correlation or is the connection causal?

It is certainly possible that educators have chosen gender parity over scientific excellence. If so, then that would help to explain their failure.

Educators may have chosen to close the gender gap at the expense of boys. They may have devalued certain types of reasoning because girls do not do as well on them. They may have changed the content of experiments to make science a more girl-friendly field?

We know that when boys believe that a field is identified as more feminine, they turn off and go back to their video games.

We know that teachers of the humanities and social sciences now actively discriminates against boys.

Is the same thing true of science?

If you read through the Department of Education report you will observe that the tests mostly involve girl-friendly and environmentally correct topics. They ask how sun-loving plants grow, how to test for pollution, and, how heat is conducted in frying pans.

Do you believe that ten or twelve year old boys will crank it up to study how to cook an omelet?

Sometimes the questions are directed at more boy friendly topics like electronic circuits and magnetic fields but they do not teach about cars, guns, and boats. They do not address questions about mining, agribusiness and construction.

Does it matter? I suspect that it does.

I think some combination of homeschooling and private schools is required if you expect your children to make a difference in the world. Young men especially will benefit from being taken out of the feminized public schools. That’s something I think about when dating and courting – picking the future teacher of my children.

Regardless, all Christians should be advocates for school choice. We shouldn’t be paying for a failed, politicized public school system. Give every parent a voucher and let the public schools compete for funding by pleasing customers – like every other business has to.

Will allowing free discussions of scientific theories hurt innovation?

9 Comments

Some people are complaining that allowing students and teachers to question and debate scientific theories will harm economic growth and raise unemployment.

Evolution News explains:

One common piece of rhetoric being lobbed against academic freedom legislation is the claim that the bills would kill jobs and have a negative overall economic effect. An anti-academic freedom op-ed in The Tennessean stated that Tennessee’s academic freedom bill would have “adverse economic consequences for the state” and asked “What high-tech employer will want to open up shop in a state that allows ideology and prejudice to trump science education?”

If you actually read that op-ed, you will find that the authors make the following arguments against academic freedom:

  1. scientific theories favored by the secular left should not be subject to falsification by scientific evidence
  2. the only reason why some people oppose secular left ideologies like naturalism (e.g. – in the origin of life) and socialism (e.g – man-made global warming) is because of religious beliefs
  3. some religious clergy accept ideologies like naturalism and socialism, so therefore everyone should have no problem with naturalistic speculations about the origin of life and doomsday predictions about catastrophic global warming – since there is no scientific reason to oppose these theories
  4. scientific theories should be accepted or denied based on the pontifications of organizations like the AAAS or teacher associations, not on the basis of repeatable experiments and measurements
  5. lawyers should be able to settle disputes about science using their ability to file lawsuits against school boards
  6. although the new law explicitly forbids bringing religion into the classroom, it would bring religion into the classroom
  7. environmental regulations, chevy volts on fire, green energy solyndra grants, cap and trade, drilling moratoriums, drilling permit delays and carbon taxes don’t hurt the economy, but allowing students and teachers to ask questions about scientific theories would hurt the economy

Now look at that last argument (#7). Is there any evidence to show that allowing academic freedom and free discussions about scientific theories and scientific evidence would hurt the economy and raise unemployment?

More from Evolution News:

In late 2010, two-and-a-half years after it passed its Science Education Act, Louisiana won the “State of the Year Award” from Business Facilities magazine, in part because of its burgeoning high-tech industry. As the magazine noted:

“The diversity and growth potential of Louisiana’s top projects in both high-tech and traditional manufacturing, as well as healthy total investments, overall job creation and innovative incentives made Louisiana a clear winner of our annual State of the Year Award,” said Business Facilities Editor-in-Chief Jack Rogers.

[…]To determine the winner, Business Facilities reviews each state’s top five projects in terms of overall investment and job creation. The magazine also evaluates the state’s execution of its economic development strategy, and the diversity and growth potential of its target industries.

“We were particularly impressed with the diversity of Louisiana’s strategy for developing high-growth sectors, including digital media, alternative energy, advanced manufacturing, and modular nuclear power plant components,” Rogers said.

The Business Facilities editor noted that Louisiana “has emerged unbowed from a series of disasters that would have brought less-determined locations to their knees — including a major hurricane, an oil spill and the national economic downturn — and charted a course for the future that positions the state to be a national leader for years to come.”

So despite a massive recession, manmade and natural disasters, and — most terrifying of all — an academic freedom law, Louisiana’s economy appears to be doing better than most all other states that don’t have academic freedom laws. It appears that in the experimental laboratory of the real world, the Darwin lobby’s claim that academic freedom bills harm the economy is resoundingly disproved.

To me, it seems intuitively true that students will be more interested in any topic where there are two sides presented fairly. No one likes to be preached at – it’s boring. I realize that some people who are lazy-brained ideologues will try to bypass a fair investigation of scientific disputes and just jump right to agreeing with their government-paid educators, but that’s not a good way of becoming educated. A better way to be educated is to consider the evidence for and against propositions, and not jump to believe whatever the people in authority say that you should believe in order to be considered “smart”. It’s better to really be smart rather than just to be told that you are smart because you agree with everyone.

What should you study to prepare yourself for a career?

Here’s an interesting post from the Chapman Kids blog. The father is a software engineer like me, and he’s serious and intentional about how he is leading his children.

In a recent post, he talks about one of the adventures that the two kids are having with a community college professor of English writing. The post is entitled “Continued conversation with the kid’s commie teacher”.

He writes:

As many already know, Kelly and Christian take a “writing” class at the community college where the dear leader of the class lectures on the evils of all things Christian, the beauty of communism and atheism, and the righteousness of drug legalization and abortion.  Today’s topic was Christianity.

[…]At the point when he made the claim that Adam and Eve could not have existed because of the scientific evidence for evolution, Christian raised his hand and said, “There is just as much scientific evidence against macroevolution as there is for it.”

“You don’t believe in evolution!” exclaimed the professor incredulously with a look of disdain and horror.

“We DO believe in microevolution.  It is grossly arrogant for you NOT to question your own beliefs when it comes to evolution” said Kelly.  “That is what you are demanding from us.”

The professor said, “Evolution is established scientific fact” and used several of the standard canards (fossil record, etc.) to establish his point.

Then they were off to the races.  Fortunately, during homeschool, Christian and Kelly had read books like The Victory of Reason:  How Christianity Led to Freedom, Capitalism, and Western Success by Rodney Stark, Understanding Intelligent Design:  Everything You Need to Know in Plain Language by William Dembski and Sean McDowell, Tactics: A Game Plan for Discussing Your Christian Convictions by Greg Koukl, and Intellectuals by Paul Johnson.  The professor was armed with shibboleths about the truth of macroevolution and quotes from John Shelby Spong about the virgin birth.  John Shelby Spong!?!!  You have to be WILDLY out of touch with both current scholarship and reality if you quote John Shelby Spong about virtually anything.  He quotes the likes of losers like Noam Chomsky and Bertrand Russell, too.

I tweeted Kelly a link to the William Lane Craig vs John Shelby Spong. Here is part 1 and part 2 of that debate on Youtube. It’s worth watching if you haven’t seen it before.

Mr. Chapman continues his post:

It is frustrating.  Here is a writing a professor who fervently believes he is making students question their beliefs through these profoundly silly arguments.  The subject matter is objectionable, but this guy’s incompetence is even more objectionable.  He does not appear to understand the difference between scientific method and historic method (very important in discussion of the resurrection).  Neither does he understand that it is impossible to argue for the primacy of scientific method without consideration of its philosophical underpinings.  I guess I should be grateful he is incompetent with respect to his arguments–he does nothing to get the kids to question their faith or worldview.  Still, a lot of taxpayer money is wasted on professors like this throughout the land.

Well, the kids have to learn how to write, but I think it is important to note English classes are especially politicized. There is an awful lot of ideology in English classes, because that’s the easiest place for people who want to teach to go if they want to avoid being corrected by real life. In English, and other similar areas, it’s easier for a teacher to go on and on about their ideas without have to test them against the real world. It’s the easiest subject for teachers to force students to agree with your ideology without allowing them to be able to bring in facts to disagree. Basically, a secular lefty teacher can always find literature (usually modern literature, blech!) that casts Christians as brutes, Christian moral standards as outdated and harmful, and non-Christian behavior as praiseworthy. Because literature is necessarily made-up – it’s just opinion.

Even someone like me who gets courting and chivalry guidance from Shakespeare and Austen is cautious about taking courses in literature. Plus, you can can get into a lot of trouble for disagreeing with the teacher. I took English electives during my undergraduate degree and they do grade you on your viewpoint, something which is much harder for them to do in math, science, physics, chemistry, etc.

Another post from Mr. Chapman discusses how children should study STEM (science, technology, engineering and math) topics, even if those children intend to work in a non-STEM field.

He writes:

I found a great article in the Wall Street Journal this morning titled Generation Jobless:  Students Pick Easier Majors Despite Less Pay.  It had some startling statistics:

Workers who majored in psychology have median earnings that are $38,000 below those of computer engineering majors, according to an analysis of U.S. Census data by Georgetown University.

Wow.  The article tells a story about a student who switched from Electrical and Computer Engineering because her team stayed up past midnight in a lab to write a soda machine program.  They could not get it to work, so to keep from getting a bad grade, she withdrew from the course.  Then she switched from engineering to a double major in psychology and policy management.  Her grades went from B’s and C’s to A’s.  She said her high school did not prepare her for the rigor of an engineering degree.

So the upshot is that she is willing to work in a low-paying career for the rest of her life because she was unwilling to do what was necessary to pass a few hard classes.  I have had this discussion with people before.  If you cannot handle a specifc course, you can do a TON of things to make it happen. You can get a tutor.  You can take the class two or even three times if needed.  You can take a more remedial course, then try the tough one again.  Is it worth it to go to school for a year or two more to do something you like and that pays well for the next forty or fifty year?  It seems like a no brainer.

The crazy part is that even for those who want to do less technical jobs, it is best to prepare for that non-technical job with a hard degree.

Research has shown that graduating with these majors provides a good foundation not just for so-called STEM jobs, or those in the science, technology, engineering, and math fields, but a whole range of industries where earnings expectations are high. Business, finance and consulting firms, as well as most health-care professions, are keen to hire those who bring quantitative skills and can help them stay competitive.

We joked about this quite a bit, but I wanted to get it into the kids head that, if they went to college (not necessarily a given–preparation for many careers–pilot, electrician, writer, and small business owner are monumentally better served through some type of preparation other than college), they could study their passion, but they needed to start with a rigorous degree.  We defined rigorous as anything that involves hard math.  The use of hard math and statistics is creating new breakthroughs in a lot of fields right now:  medicine, agriculture, sociology, etc., etc. etc.

I agree with Mr. Chapman. And I think that he is definitely going to raise successful, influential Christians, because he and the children are well prepared and engaged. He has a great relationship with his kids. They are definitely more advanced than I was when I was their age. It’s encouraging to me to see a Christian Dad who is focused and purposeful about having solid relationships with his kids, and preparing them for the dangerous world they are entering as adults. I think it’s important to admire the people who are getting it right (the parents and the kids together) and learn from their successes. I like that he is still involved with what his children are learning even after they are finished with high school.

I really do think that engineers make the best husbands and fathers. Engineers learn how to gather requirements, evaluate alternative solutions, and then implement. Engineers care about designing to support expandability, maintenance, security and unexpected emergencies. They are easy to argue with, because they believe in logic and evidence. They are pragmatic – they make decisions based on what works, not what sounds good or feels good. Good engineers also have training in project management, budgeting, leadership and resource management, too. The best engineers are the entrepreneurs, who understand business, economics, business law and politics. It really is an ideal skill set for marriage and parenting. Engineers try to build things, and those building skills can be re-used to build a family.
