I just wanted to say your science section is dead on.
I'm a chemistry teacher in Illinois with a Masters degree in my content area
and the nonsense that the "education elites" are pushing is disgusting.
We are creating a generation of science idiots thanks to the hands-on, touchy feely way
of teaching these people are pushing.
-- a reader, October 2009
In too many American schools, the science program consists of little more than
a) Cute animals and their environments,
b) People are evil and are destroying the Earth,
c) Sex and drugs and
d) Measuring things.
The actual science content has been so
eviscerated that one education expert derides the result as "science appreciation"
rather than science.
In many schools, there is vanishingly little effort to promise parents that
their children will actually learn about science.
Fun projects certainly add spice to a science class, but what ever happened
to learning anything?
Go get your parent handbook (if your school even bothers with one) and take a look
under "science". Does it prattle on about "experiencing science", or the
"scientific method", or "skills of reasoning and discovery", or such like that?
Does it enthuse about having lots of "experiments" and "hands-on discovery"?
After going through all that, the real test is this ... does it ever get around to promising that
your children will actually be taught
factual knowledge about science? If not, welcome to fuzzy science.
What's happening here? Read on...
"Hands-On" vs "Minds On"
Note: For your convenience in printing, this section on "hands-on" science
is also available on a webpage by itself.
Your child's school keeps on expanding "hands-on" "discovery"
activities in science class, and you're wondering, "But when are they actually
going to learn anything?"
And yet it is difficult to resist the allure of hands-on activities.
When you visit a class of second graders dropping things into bowls of water
and making notes on which things float, what you first see is a roomful
of happy kids, pretty much enjoying what they're doing.
Only upon reflection does a glimmer of doubt set in: What,
if anything, were those kids actually learning?"
Those who argue in favor of discovery learning like to frame the
argument in terms of either-or: Should children merely learn boring
facts, or should they immerse themselves in hands-on activities?
The problem is that's a straw man argument:
No one is arguing that knowledge
is a substitute for understanding, only that it is a prerequisite
for understanding. The education theorists want to portray
content knowledge as a poor substitute for understanding,
as though we were arguing for priming a wall instead of painting it.
But just as a wall must be prepared and primed before final paint
coats are applied, understanding of science is crucially dependent
on acquisition of a vocabulary and base of knowledge about science.
Knowledge is the basis for understanding, and when that base
knowledge is developed or developing, hands-on activities can
add vitality and engagement.
"Hands-on investigative activities ought to
be sprinkled into a science program
like a 'spice'; they cannot substitute for a 'main dish'."

- Projects vs. Learning:
The heavy use of so-called "discovery" projects in science often
has more to do with fashionable au courant theories than it
does about learning science. The constructivist, "discovery"
theory of education is responsible, indeed, it is at the root of
much of the wasted time and lack of substance in all subjects
in K-12 education.
For much more on this, we have devoted a full
section of this website to the question of
Projects vs. Learning
"Minds-On" Science Education, Science News, April 27, 1996. A professor of biology writes,
"... there comes a time, starting in middle school or high school, when
students must acquire a body of knowledge. How can they do this and
still have the hands-on science that everyone is calling for?
Hands-on science moves far too slowly for them to acquire a body of knowledge."
Another person writes,
"Having students formulate and carry out experiments is an important
part of their education. ...
However, making this the main curriculum is misguided. In doing
research, students learn facts at a snail's pace. If they are ever to
become scientists, they need to stand on the shoulders of those who
came before them.
For a more thorough overview of this topic, read Dumbing
Down Our Kids by Charles J. Sykes. Meanwhile, parents need to insist on proven
techniques in the education of their children."

- Which Ionic Compound Would You Like To Be?
by Margaret White, Globe And Mail [Canada]
June 16, 2005.
"Attention, parents. Teachers don't teach science the way they used to. ...
If you're interested in scientific literacy, you may be
interested in the trendy notions that have infected modern science teaching.
Drill 'n' kill has been replaced by something called discovery learning, in which
students are encouraged to stumble across the theory of relativity all by
"That's not all. Science teachers are encouraged to make their material accessible
and touchy-feely, so kids will feel good about it. 'If you were transformed into
an ionic compound, which would you be?' asks a sample test question included in
Nova Scotia's official science curriculum. No, this question isn't for Grade 5s.
It's for Grade 11s. In British Columbia, Grade 11 (!) students are instructed:
'You are a moss. Describe your experiences.' ...
"You are a moss.|
Describe your experiences."
"Experiential, child-centred learning is the order of the day. Drop in on any
science class and you're likely to discover groups of kids huddled together doing
projects as the teacher looks benignly on. The teacher is there not to instruct,
but to facilitate. This is fine as far as it goes. But it's gone overboard.
'Little Emile is supposed to go out and investigate things as if he were
Archimedes and Newton all rolled into one,' says [one teacher]"...
"There's a fair bit of evidence that teacher-led instruction, high expectations
and frequent tests work better than child-centred learning, especially in the
early years. There's also quite a bit of evidence that people who have a
background in and passion for their subject are better teachers than those who
don't. But who needs evidence? The real question is, which ionic compound would
you like to be?"
- In Scientific American (November 1997), Douglas R. O. Morrison writes a review of
Alan Cromer's book
Connected Knowledge: Science, Philosophy, and Education.
This review is not now available online (except as a
purchase), but here are some excerpts:
"I began to wonder some years ago why my children were learning
science in such a crazy fashion. Teachers told them to do lab
experiments but gave them no textbooks or notes to explain why they
were doing those experiments or what they meant--evidently, the
students were supposed to work it all out for themselves.
"At a PTA
meeting, I protested and was told that this was the new fashion in
education. None of the other parents, I was informed, had made any
complaint, except the ones who were scientists. This circumstance
seemed to me to indicate a problem.
"Most scientists have never heard
of the 'Science Wars'; they are too busy working to worry about how
sociologists think their enterprise progresses. But it is becoming
increasingly common knowledge that a harmful vision of science has
been steadily taking over education in schools
I often hear American scientists lament the low standard of education
in their public schools. After reading Cromer's explanation of how
constructivists have worked their ideas into science teaching
programs and introduced their nonscientific ideas, I can well
understand how these actions have exacerbated the problems."
Improving Mathematics and Science Education: A Longitudinal
Investigation of the Relationship Between Reform-Oriented Instruction
and Student Achievement (PDF), Rand Corporation, 2006.
When someone announces they are going to study "Reform-Oriented Instruction" you have to think that they're
going into the project laden with a bias. Nonetheless, this impressive study comes up with some
surprisingly candid observations about constructivist
math and science. For example:
"weak ... nonsignificant ... weak ... negative ... nonsignificant ... weak ... less effective"
- "Despite large investments in the
promotion of reform-oriented curricula and instruction, the evidence
supporting the effectiveness of these practices in raising mathematics
and science achievement is relatively weak."
- "The first research question concerned the relationships between exposure
to reform practices and student achievement. We found that exposure
to reform-oriented instruction generally had nonsignificant or
weak positive relationships to student achievement in both mathematics
and science, with the exception of groupwork-related practices in
mathematics (for which the relationships were negative)."
- "The second research question asked whether the relationship was
affected by the way achievement was measured. ... findings
suggest that relationships between instruction and achievement
can depend on how achievement is measured."
- "We found nonsignificant or weak positive relationships between
reform-oriented instruction in mathematics and science and student
achievement measured using multiple-choice tests."
- "Many teachers believed
that the reform-oriented practices were likely to be less effective than
other kinds of practices for promoting high scores on state accountability
- "Perhaps the most important unanswered question regarding
reform-oriented instruction concerns benefits and costs. [These] mathematics
and science initiatives [are] relatively expensive... And, although they appear to
have had some effects on mathematics and science teaching, this study
did not address whether these changes in practice and the associated
improvements in achievement were worth the cost."
Igniting a Fire to Learn
by Mitchell Landsberg, Los Angeles Times, May 24, 2006.
"Prodded by an unusual teacher, kids at 112th Street Elementary 'eat, drink, breathe science' --
and take on a top charter school. ...
Jazmani Busby has learned things in her nine years that no child
should have to learn.
She has learned to drop to the floor at the sound of a gunshot. She
has learned what an AK-47 looks like. ... Jazmani, a lifelong
resident of the Nickerson Gardens housing project in Watts, doesn't
like to talk about these things. When she calls her best friend,
Raquel Hernandez, the two fourth-graders are much more eager to talk
about something else they've learned, something that makes them
bubble with excitement. Science.
Their mothers have gotten used to it. The phone will ring, and
Jazmani and Raquel will start gabbing about exoskeletons and
endoskeletons, arachnids and crustaceans, photosynthesis and cell
'Science is my life,' Jazmani explained. 'I eat, drink, breathe
science. I just love science.' ...
Principal Brenda Manuel says, 'The kids are just on fire about science.' How did this happen? ...
The children of 112th Street are on fire about science because a
teacher named Stan White came into their lives last fall like a
blowtorch -- a large blowtorch with a wide smile, a shaved head, a
crisp no-nonsense manner and a deep-seated belief that these children
are as capable of excelling as any children anywhere. ...
It's old-fashioned and rote, and it seems to work."
Editorial: Less Fun, More Science
Cleveland Plain Dealer, April 29, 2006:
"... As part of the long-running Trends in International Math and
Science Study (TIMSS), researchers videotaped eighth-grade science
classes in four high-achieving countries and the United States.
An exhaustive analysis of the recordings, released this month, shows
that teachers in the United States spend markedly more time than
international peers working to motivate students with games and
puzzles. U.S. students also spent more time than others doing
activities without a direct link to learning actual scientific
concepts, and were held to lower expectations in taking
responsibility for their own science learning. ...
teachers abroad seemed to feel less need than American teachers to make science
'fun' and instead focused squarely on conveying information."
"U.S. students ... spent more time ... doing activities without a direct link to learning"
- Often, the best judge of effective teaching is a student,
rather than ivory tower theorists or teachers steeped in the latest fads.
From our page on Scary Web Postings,
here is a terrific exchange between a young teacher and a student:
[A teacher posts this message:]
What teaching or other methods have you found to be
successful in motivating and stimulating students to learn,
especially college or HS biology/science? Active learning
ideas? Group activity ideas? Lab based instruction methods?
Problem sets / case studies?
[A student replies:]
I am a college junior currently taking
a Physical Science course
... I think that it is probably the worst class that I have ever taken,
the instuctor doesn't
teach. She basically stands in front of the room, mentions something
and then has the class discuss it in small groups. ...
Also, almost all of the class activities are done in groups. Even part
of each exam is a group problem. I think that some group work is okay,
but not all the time. I like to do projects on my own because I can get
them done and not have to wait for the rest of my group.
- From the excellent book Dumbing
Down Our Kids by Charles Sykes, Amazon

featuring an eighth-grade class bored to tears by a science
program that is heavy on "hands-on" meaningless activities but
light on learning:

The Equivalence of Learning Paths in Early Science Education: Effects
of Direct Instruction and Discovery Learning (PDF) by David Klahr and
Milena Nigam, Psychological Science, 2004. The conclusions of this study merit special emphasis:
"We found not only that
many more children learned from direct instruction than from
discovery learning, but also that when asked to make broader, richer
scientific judgements the (many) children who learned about
experimental design from direct instruction performed as well as
those (few) children who discovered the method on their own."
Empirical Evidence About Science Learning From Unguided Instruction,
(PDF) excerpt from paper
Why minimal guidance during instruction does not work:
An analysis of the failure of constructivist, discovery, problem-based experiential and inquiry-based teaching
by P. A. Kirschner, J. Sweller, and R. E. Clark, Educational Psychologist, 41(2), 75-86 (2006).
"The work of Klahr and Nigam (2004), discussed earlier, unambiguously
demonstrated the advantages of direct instruction
in science. There is a wealth of such evidence. A series
of reviews by the U.S. National Academy of Sciences has recently
described the results of experiments that provide evidence
for the negative consequences of unguided science instruction
at all age levels and across a variety of science and
math content. McCray, DeHaan, and Schuck (2003) reviewed
studies and practical experience in the education of
college undergraduates in engineering, technology, science,
and mathematics. Gollub, Berthanthal, Labov, and Curtis
(2003) reviewed studies and experience teaching science and
mathematics in high school. Kilpatrick, Swafford, and
Findell (2001) reported studies and made suggestions for elementary
and middle school teaching of mathematics. Each of
these and other publications by the U.S. National Academy
of Sciences amply document the lack of evidence for unguided
approaches and the benefits of more strongly guided
instruction. Most provide a set of instructional principles for
educators that are based on solid research. These reports
were prepared, in part, because of the poor state of science
and mathematics education in the United States. Finally, in
accord with the ATI findings and the expertise reversal effect,
Roblyer, Edwards, and Havriluk (1997) reported that teachers
have found that discovery learning is successful only
when students have prerequisite knowledge and undergo
some prior structured experiences."
"Discovery learning is successful only when students have prerequisite knowledge"
Instruction Versus Exploration In Science Learning:
Recent Psychological Research Calls "Discovery Learning" Into Question
by Rachel Adelson, Monitor on Psychology, American Psychological Association, June 2004.
Subhead: "Klahr's controlled studies demonstrate that, at least for many of the multistep
procedures used in science, direct instruction works and generalizes better." Excerpts:
"direct instruction works and generalizes better"
"Welcome to the fourth-grade science fair, with its baking-soda
volcanoes, bread mold grown in drawers, proud parents and thoughtful
judges. The teachers can't help but wonder if the young would-be
scientists can tell good science from bad. In science, how is
critical thinking best taught?
This question may be answered by David Klahr, PhD, a psychology
professor at Carnegie Mellon University, and Milena Nigam, a research
associate at the University of Pittsburgh's Center for Biomedical
Informatics. They have new evidence that 'direct
instruction' -- explicit teaching about how to design unconfounded
experiments -- most effectively helps elementary school students
transfer their mastery of this important aspect of the scientific
method from one experiment to another. ...
[D]iscovery learning has persisted, [Klahr] says, partly because of a lingering notion
that direct instruction would not only be ineffective in the short run, but also
damaging in the long run.
Piaget thought interfering with discovery blocked complete understanding.
More recent cognitive research, says Klahr, shows that 'this is just plain wrong.'"

Fat in California's Budget by Thomas Sowell, June 21, 2004.
Excerpt: "[In a recent article] the Mathematics Engineering Science Achievement program
(MESA) is praised because it helps students become 'excited' about
math and science. 'Exciting' is one of the big fad words in
educational circles, as if getting your emotions worked up is the
same as mastering skills.
In keeping with the excitement theme, students in this program are
pictured making balloon-powered rockets and one of them is quoted as
saying that this program "inspires" him to go to school.
One of the teachers in this program calls it 'crazy' to cut the
program -- 'as he watches another balloon-powered rocket fly across
the room.' But just what is this actually accomplishing?
The teacher says, 'Look at this: It gets a bunch of diverse cultures
into one room to build things. You always feel like a family here.
It's just a good place.'
But actual bottom-line results in terms of math and science? ...
Apparently the state legislators have not been too foggy to spend
$85 million of the taxpayers' money to bankroll this program that
apparently cannot show hard evidence of serious improvement in math
and science, as a result of balloons flying across the room in this
"He watches another balloon-powered rocket fly across
the room. But just what is this actually accomplishing?"
The Dumbing Down Of Science In Education
by Mike Horne. This is an interesting essay on why teachers and scientists
find it necessary to "dumb-down" science in the classroom, public lectures
and in the news. A special emphasis is placed on dumbing-down of
museum exhibits about science.
Illinois Standards for Science
The Illinois State Board of Education would have you believe that our
official state standards for science education are tough and demanding.
Yeah, right. What could possibly be the point of a science standard that
doesn't even mention "mammals", "machine", "electronics", "acid",
"radiation", "reptile", "dinosaur", "muscle", "brain" or "astronomy"?
Here is our compilation of some
words that do not appear anywhere in the
Illinois science standard, for any grade level from first grade
through senior year high school.
The whole movement for educational standards are supposed to ensure
a high goal of academic content and achievement, right? Well,
one parent (who endured a putative parent-teacher committee looking into the local
public school's science curriculum) saw first hand how a weak Illinois state standard
gave the school license to thumb its nose
at serious, meaty standards such as those of California or Core Knowledge.
In an attempt to point out the anemia evident in the Illinois standards,
that parent wrote this proposal for his school, including a
detailed point-by-point comparison of the Illinois and
California science standards (this is a downloadable PDF document).
- In a
special report in the Spring 2008 issue of American Educator
(American Federation of Teachers), the AFT scored Illinois' science standards:
- The Illinois Science standards DID NOT MEET criteria at the Elementary level
- The Illinois Science standards DID NOT MEET criteria at the Middle school level
- The Illinois Science standards DID NOT MEET criteria at the High school level
Fordham: Review of State Science Standards
National "Standard" for Science???
Much has been made of the "National Science Education Standards" (NSES), a document which was developed by
education insiders under the banner of leading science organizations. However, the content and approach
of these supposed "standards" have not been endorsed by the scientists of the groups involved, nor in any
way do they represent actual national "standards."
- Bastiaan J. Braams, on the mathematics faculty of New York University has researched the background and status
of the NSES. Here is his
critique of the NSES that he directed to the Committee on Education of the
American Physical Society.

but unsupported "standards" in science.

appalled and frustrated by the dictums of the National Science Foundation
when it comes to teaching science and math, read this article.
Mrs. Cheney reports on Alan Cromer's dissection of just who is running
the show at the NSF.
The "Scientific Method"
Modern schools spend an extraordinary amount of time discussing "the
scientific method." This emphasis follows directly from a strongly
constructivist approach to science education. Students are drilled
in definitions of "the scientific method." They do some project
("which of these things float?"), do lots of measurements, and then
write essays about their "experiment." The kids are busy, and they
usually report that this was "fun." But in the process of adding
experiments, acquisition of content knowledge too often is
diminished. We often find that the kids have actually gained
very little useful knowledge or even understanding.
Dr. James Trefil, a noted professor of physics, wrote an essay
"Two Modest Proposals Concerning Scientific Literacy" in which he declares,
"If you expect students to know something, you have to tell them what it is."
In defense of that proposition, he writes,
"There is a common divide among those engaged in scientific
literacy, roughly characterizeable as a divide between advocates of
content versus advocates of method. ... (For the record, I am
closer to the content end.)
[This] proposal is designed to counter what I see as an
excessive move among modern educators toward the method end
of the spectrum. In its most extreme form, this move
works directly against the goal of scientific literacy.
... [L]et me state the method position as follows: There is
something called the scientific method, and someone who
understands this method will be able to understand all of science,
regardless of the specific subject matter that person
has been taught. Thus the goal of science education should be to
teach that method. It's hard for me to understand how anyone could
hold a position that is so clearly untenable. ...
Even some of those who are cheerleaders for
"discovery" activities and projects decry the time wasted
on formulaic observance of a supposed "scientific method."
Here is a good example:
The fact of the matter is that in order to be scientifically
literate, the citizen needs to know a little bit about every
field of science. He or she also needs to know a little about the
scientific method as well, but that can't substitute for knowledge of the
basic facts. ...
In short, if we expect students to know a little bit about every branch
of science, then we have to teach them a little bit about
every branch of science."
-- Dr. James Trefil,
"Two Modest Proposals Concerning Scientific Literacy,"
an essay in "Science Literacy for the 21st Century."
Bolding added for emphasis.
"Precollege students, and the general public for that matter,
believe in a distorted view of scientific inquiry that has
resulted from schooling, the media, and the format
of most scientific reports. This distorted view is called
The Scientific Method, that is, a fixed set and sequence of
steps that all scientists follow when attempting to answer
scientific questions. ...
The perception that a single scientific method exists owes
much to the status of classical experimental design. ...
The problem is that experimental research is not representative of scientific investigations as a whole.

Science as a Meaningful Context for Learning in Science,"

Critical Thinking: Why Is It So Hard to Teach?
by Daniel T. Willingham, professor, Department of Psychology, University of Virginia.
In this extremely thought-provoking article, Dr. Willingham raises crucial questions
about what it means to "think like a scientist" in a school setting.
A key conclusion: scientific thinking depends on scientific knowledge.
Here's one of his examples:
More formal experimental work verifies that background
knowledge is necessary to reason scientiically. For example, consider devising a research hypothesis. One could
generate multiple hypotheses for any given situation. Suppose you know that car A gets better gas mileage than car
B and you'd like to know why. There are many differences between the
cars, so which will you investigate first? Engine size? Tire pressure? A key determinant of the hypothesis
you select is plausibility. You won't choose to investigate a difference between cars A and B that you think
is unlikely to contribute to gas mileage (e.g., paint color), but if someone provides a reason to make this
factor more plausible (e.g., the way your teenage son's driving habits changed after he painted his car red),
you are more likely to say that this now-plausible factor should be investigated.
One's judgment about the plausibility of a factor being important is based on one's knowledge of the domain.
- What methods do real scientists really use?
Is science about understanding the world, or about methods?
From our page on education quotations,
here are some thoughtful comments on the
so-called "Scientific Method":
What Real Scientists Actually Do
"I do not frame hypotheses"
-- Isaac Newton
"It has become fashionable in science education to mold K-12
students around an idee fixe of a modern scientist;
formulating hypotheses, observing measuring, and discovering
through hands-on investigations.
What has been left unsaid is that real scientists don't
actually spend very much of their day 'observing' and 'measuring.'
They read! Reading for understanding of content is the core
process skill of science, and there is no substitute for
practice at an early age. ...
-- Dr. Stan Metzenberg,
"Reading: The Most Important Science Process Skill"
"A scientist works largely by intuition. Given enough experience,
a scientist examining a problem can leap to an intuition as to
what the solution 'should look like.' ...
Science is ultimately based on insight, not logic."
-- Brother Guy Consolmagno, Ph.D., S.J., "Brother Astronomer."
"The most exciting phrase to hear in science, the one that heralds the
most discoveries, is not 'Eureka!', but 'That's funny...'"
-- Isaac Asimov
"In the field of observation, chance favors the prepared mind."
"Research is what I do when I don't know what I'm doing"
-- Wernher Von Braun
Prof. Barnhardt: "You have tested this theory?"
Klaatu: "I find it works well enough to get me from one planet to the next."
-- dialogue from The Day the Earth Stood Still
Some quotes from "On Scientific Method", by Percy W. Bridgman,
from his "Reflections of a Physicist" (1955):
- It seems to me that there is a good deal of ballyhoo about scientific method.
I venture to think that the people who talk most about it are the people
who do least about it. Scientific method is what working scientists do,
not what other people or even they themselves may say about it.
No working scientist, when he plans an experiment in the laboratory,
asks himself whether he is being properly scientific, nor is he
interested in whatever method he may be using as method.
- Scientific method is something talked about by people standing on the
outside and wondering how the scientist manages to do it.
- But ... the working scientist ... is not
consciously following any prescribed course of action, but feels complete
freedom to utilize any method or device whatever which in the particular
situation before him seems likely to yield the correct answer. ...
No one standing on the outside can predict what the
individual scientist will do or what method he will follow.
- In short, science is what scientists do, and there are as many
scientific methods as there are individual scientists.
Science Is About Knowing
Our English word "science" is derived from the Latin word scientia, which
means "knowledge". It does not mean "method" or "discovery."
"Science is the knowledge of consequences, and the dependence
of facts upon one another."
-- Thomas Hobbes
"Having students formulate and carry out experiments is an important part of
their education. That is why schools sponsor science fairs. However, making this
the main curriculum is misguided. In doing research, students learn facts at a
snail's pace. If they are ever to become scientists, they need to stand on the
shoulders of those who came before them."
-- Sally Levinson
"There comes a time, starting in middle school or high school, when students
must acquire a body of knowledge. How can they do this and still have the
hands-on science that everyone is calling for? Hands-on science moves far too
slowly for them to acquire a body of knowledge."
-- Ralph W. Lewis, Professor Emeritus of Biology, Michigan State University
"Many of the popular hands-on kits in current use provide no
reading materials for students at all, and this is the fulfillment
of the constructivists' dream. For everyone else it is a nightmare. ...
"A student who has not developed the skill of learning through
reading has no professional future in science.
Without a foundation in scientific vocabulary and with minimal knowledge of
scientific fact, their words bear an accent of ignorance that is
impossible to conceal and nearly impossible to remediate.
While young people should be encouraged to enter science, they must also
be given the education that will permit them to succeed.
"Hands-on investigative activities ought to be sprinkled into a science program
like a 'spice'; they cannot substitute for a 'main dish'.
The best 'hands-on' program would be one in which students can get
their 'hands on' an informative textbook!"
-- Dr. Stan Metzenberg,

Science Textbooks and Programs
- Suggestions on Evaluating Science Textbooks
by Kevin Killion, March 17, 1999.
In seeing presentations from science textbook publishers, it was easy to quickly
discern glaring errors,
silly time-wasting activities, and low interest in substantive
content standards. With rare exception, publishers have managed to take the excitement
and wonder of science and turn it into mindless and boring makework projects.
These suggestions suggest
some considerations in considering science curricula and textbooks.
The state of California has some of the most substantive and useful science
standards in the country, and avoids fad-laden curricula.
Here is the California State Board of Education's
reviews of 16 specific science programs (PDF file), adopted in March 2000. (Note that these reviews
consider the California editions, and there may be differences in other editions.)

A School Science Fair: What Are The Kids Learning?
by Kevin Killion, July 31, 2001.
A visit to a local grade school science fair raises troubling issues
about excessive emphasis on a supposedly universal "scientific method",
the nature of a hypothesis, the heavy investment of time,
work being done by parents
and whether the children actually are learning very much. Sections of this paper include:
- "Scientific Method"?
- Control vs. Test
- Evaluation of Results
- Can Children Test Hypotheses?
- Gender Equity
- An Anachronism?
- If You Must Have A Science Fair
- Here's an alternative to the usual science fair: The "Science Olympiad"
is gaining favor as a more lively and possibly
more educational alternative to traditional science fairs.
It's certainly not the ideal: The official website prattles on about vaguely wanting
"to develop teamwork and cooperative learning strategies" (ugh!)
"with an emphasis on problem solving skills and hand-on, minds-on constructivist learning practices"
(yikes!) Having said that, the program seems more oriented towards actually
learning science rather than an imaginary "scientific method."
Find out more at the
Illinois websites for the Science Olympiad.
- As another alternative to science fairs, one concept that is gaining favor is
that of a "science expo" wherein kids are free to make a study of some
area of science they are interested in, and report on what they
learned and found fascinating. The whole notion of a unique and
pure "scientific method" is deemphasized to a more appropriate level.
Science and Schools
The state test scores for one suburban public school were unsettling:
The school was third from the bottom of the heap,
while another small, one-school district (Bannockburn) had stellar results.
What was Bannockburn doing
that the other school was not? Here is a report

Popular Culture and the Threat to Rational Inquiry
by Douglas R. Hofstadter. Excerpt:
"When I was growing up science was not sugar-coated. By this I mean that science,
when presented to children and teens, was not combined with irrelevancies ...
It never occurred to me that science was some kind of 'bitter pill' that
needed sugar-coating. No, for me, science ...
was already filled with alluring romance and enticing mystery. ...
Today's sugar-coated television science shows would have totally turned me off
when I was a child, and perhaps they turn children off today
-- those who, like me, are lured by mystery, those who prefer a schematic,
black-and-white diagram to a full-color, glossy set of photographic images
that dazzlingly capture the surface of some phenomenon but convey nothing
of what lurks behind the scenes."

Why Can't a Woman Be More Like a Man?
Women earn most of America's Ph.D.'s but lag in the physical sciences. Beware of plans to fix the 'problem.'
by Christina Hoff Sommers, resident scholar at the American Enterprise Institute,
The American, March/April 2008.
"Women now earn 57 percent of bachelors degrees and 59 percent of
masters degrees. According to the Survey of Earned Doctorates, 2006
was the fifth year in a row in which the majority of research Ph.D.'s
awarded to U.S. citizens went to women. Women earn more Ph.D.'s than
men in the humanities, social sciences, education, and life sciences.
Women now serve as presidents of Harvard, MIT, Princeton, the
University of Pennsylvania, and other leading research universities.
"But elsewhere, the figures are different. Women comprise just 19
percent of tenure-track professors in math, 11 percent in physics, 10
percent in computer science, and 10 percent in electrical
"So why are there so few women in the high echelons of academic math
and in the physical sciences? ...
"The power and glory of science and engineering is that they are,
adamantly, evidence-based. But the evidence of gender bias in math
and science is flimsy at best, and the evidence that women are
relatively disinclined to pursue these fields at the highest levels
"When the bastions of science pay obsequious attention to
the flimsy and turn a blind eye to the serious, it is hard to
maintain the view that the science enterprise is somehow immune to
the enthusiasms that have corrupted other, supposedly 'softer
academic fields. ...
"American scientific excellence is a precious national resource. It is
the foundation of our economy and of the nation's health and safety. ...
Will an academic science that is quota-driven,
gender-balanced, cooperative rather than competitive, and less
time-consuming produce anything like these results?"

Teachers Without License
by Benjamin DeGrow, May 25, 2006.
"Smart and capable professionals who want to impart their expertise to
high school students should have a clearer path to the classroom.
Seeking to expand students' horizons, one Colorado school district
has unveiled a creative plan to enlist the services of 'real world'
specialists who don't have the time to acquire a teaching license.
Leaders of the Douglas County School District two weeks ago announced
to the Colorado State Board of Education their intention to request
waivers from the state's teacher licensure requirements. Concerned
that not enough pupils are prepared to compete for high-level jobs in
the international marketplace ... the district wants to hire nontraditional
'real world' teachers, including community members highly skilled in
engineering and foreign exchange instructors who can offer more
languages to students. However, most of these busy professionals do
not have the time or interest to wade through the lengthy process and
paperwork to become licensed."
Colorado School Seeks Permission to Hire Scientists to Teach Science,
June 15th, 2006.
"[L]eaders of the Douglas County School District in Colorado have requested waivers
from the state so that professional scientists and engineers can
teach science to students. The question is why they need licenses in
the first place. If a Ph.D. makes one qualified to teach students who
are paying tens of thousands of dollars to attend universities, why
should a person with a Ph.D. need approval to teach high school
courses? Government licensures shouldn't prevent knowledgeable
people from teaching, especially when they are instituted to ensure
teacher quality. Making professional scientists first seek approval
from the government to teach only protects less qualified teachers
More Foreigners Getting Advanced Science-Engineering Degrees
National Center for Policy Analysis , March 30, 2005.
"Foreigners are earning a greater percentage of science and
engineering doctorates from U.S. universities than ever before. ...
In 1966, foreign-born students received 23 percent of
science-engineering doctorates. By the year 2000, they received 39
percent of those doctorates. This occurred even as the United States
expanded its Ph.D. educating capacity -- America graduated 11,000
more Ph. Ds in 2000 than in 1970."

Science has helped our civilization move from primitive beginnings to advanced
technological societies. Lifespan is greatly lengthened, and many diseases have
been conquered. In more recent years, many forms of pollution have been
drastically reduced, industrial and automotive emissions have been slashed.
There is much more to be done, of course. But too often environmental
issues are treated in many school lessons with non-stop despair,
focusing on science and technology as a blight rather than as a vehicle
of human advancements and a better world.
In some cases, this "environmania" in schools is well-intended and simply
naive. In others, it emerges from a more deep-set political agenda.
Here are some links on rampant enviromania in schools. Note that some of these
links, while bringing up interesting questions, are in themselves politically
charged! If nothing else, the bottom line is that environmental questions do
not have easy, obvious answers and that environmental education must
reflect the complexity of the issues and the full spectrum of viewpoints.
- An online excerpt from the excellent and highly recommended book,
"Facts, Not Fear: Teaching Children about the Environment" by Michael Sanera and
Jane S. Shaw: "Childhood was once supposed to be idyllic and carefree. Children
were allowed to be children. But today many schools are plunging our children
into serious environmental activism. ... We want our children to learn good citizenship.
We don't want them to be polluters when they grow up. But often, instead of
being taught information that will lead to intelligent choices in the future,
they are being enlisted in trendy causes and sent out to bring their parents 'on board.'
In the past, most environmental education was called ecology and it was taught
as a part of science. ... Starting in the 1970s, however, as interest in the
environment exploded throughout the country, 'environmental science' began to crowd
out traditional science. Environmental education spread from junior high and high
school to the primary grades, while invading other subjects in an oversimplified way.
Texts on health, geography, and history now typically contain one or more
environmental chapters. Unfortunately, the textbook authors often know little about the environment."

Saving the Planet Without Scaring Kids to Death:
Parents need facts to counter environmental extremism in the classroom
by George A. Clowes, School Reform News, October 1, 1997.
Excerpt: "A six-year-old girl gets a new bed, but she's sad because
'They killed trees to make my bed.' A five-year-old boy sees clouds obscure
the moon and exclaims,
'Look at the pollution!' A second-grade class's Christmas wish is 'for a new
Earth' because we have destroyed ours through 'pollution, disappearing
rainforests, and the elimination of the ozone layer.' A nine-year-old warns
former President Bush, 'Mr. President, if you ignore this letter, we will all

On Coercive Environmental Education by Jo Kwong, Acton Institute, March/April 1995.
"In The Religion of Environmentalism, John K. Williams wrote 'Extreme
environmentalism ... is a decidedly dangerous religion. Its vision
of the world and of humanity's place in it reeks of superstition.
The pattern of behavior it prescribes is morally grotesque.'
Williams' sentiments are hardly unique. A growing number of people
are disturbed by the methods and strategies used by the
environmental special interest movement, particularly in the realm
of environmental education."
Green Zombies by Henry Lamb, June 15, 2002. Excerpt:
"Are our schools producing green zombies? Ask any student in any grade what
causes global warming; odds are that their reply will be cars, or
fossil fuels or 'human activity.' ...
Public schools are brainwashing our kids. Rather than teach the science that
underlies the global-warming debate so the students can make their own
informed decisions, educators are brainwashing them and calling it English,
or math or history."

Educational Indoctrination, Environmental Style
by Ari Kaufman, Opinion Editorials, January 21, 2006.
"During my ephemeral teaching career in Los Angeles, there were
numerous troubling examples of educational ludicrousness and lunacy.
Of all the examples, the environmental indoctrination of my
students was the most disconcerting. ...
It wasn't only that the students were regularly pulled from my class
at inopportune times to have the same information ingrained into
their ten year-old minds, but rather, that the messages a high
percentage of these groups pontificated were that human beings are
inherently bad people, animal killers, and are ruining our

"Critics say science books being proposed for Texas school kids could
be more agitprop than proper facts, and it has some of them hopping mad.
... While it's not unusual for there to be criticism of the content of

this year some critics are suggesting the books more closely resemble
political science books than science books."
Inaccurate Textbooks Nixed by Kenneth Green. Excerpt:
"Students should be presented with the facts about the environment
without gross distortions. The State Board of Education recently made a
brave decision, rejecting two proposed environmental textbooks that were
not only factually erroneous but also blatantly biased. The publisher of
one of the rejected books has since agreed to remove the bias and correct the errors."

Why Fight Over Intelligent Design?
by Andrew J. Coulson, Cato Institute, November 22, 2005.
"Supporters of the theory of human origins known as 'intelligent
design' want it taught alongside the theory of evolution. Opponents
will do anything to keep it out of science classrooms. The
disagreement is clear.
But why does everyone assume that we must settle it through an
ideological death-match in the town square? ...
We're fighting because the institution of public schooling forces us
to, by permitting only one government-sanctioned explanation of human
origins. The only way for one side to have its views reflected in the
official curriculum is at the expense of the other side.
This manufactured conflict serves no public good. After all, does it
really matter if some Americans believe intelligent design is a valid
scientific theory while others see it as a Lamb of God in sheep's
clothing? Surely not. While there are certainly issues on which
consensus is key -- respect for the rule of law and the rights of
fellow citizens, tolerance of differing viewpoints, etc. -- the origin
of species is not one of them.
The sad truth is that state-run schooling has created a multitude of
similarly pointless battles."
The Education Monopoly and Intelligent Design,
by D. Eric Schansberg, professor of economics at Indiana University Southeast
and adjunct scholar at the Indiana Policy Review and the Acton Institute. Excerpts:
"... This issue provokes such controversy because the dominant provider
of education has such strong monopoly power, and most consumers have
little ability to avoid its dictates. ...
If one group wants their children taught sex education with cucumbers and
condoms in the fifth grade, then that should be their prerogative.
But that shouldn't be forced on other people. Another contentious example
is school prayer. Some parents want a prayer to Jesus Christ.
Many parents want a prayer to the lukewarm deity of civil religion.
Others want no prayer at all or prayer to other gods. By providing options,
school choice deals with such issues in a far more effective manner than a
government entity with significant monopoly power. ...
For self-proclaimed liberals, this should be an easy decision, given their
usual penchant for individual choice and support for the poor. ...
Science, religion and politics. Real wars and now 'culture wars' have been
fought in their name. Let's put down our weapons and give all Americans
freedom to educate their children as they see fit."
Separating School and State
by Jeff Jacoby, Columnist, Boston Globe, June 12, 2005. Excerpts:
"Recent dispatches from the education battlefront:
Kansans have been debating how the development of life on earth should be
taught in public schools -- as the unintended result of random evolution
or as the complex product of an evolution shaped by intelligent design.
The board of education is to decide this summer whether the science
standards should be changed. Kansas is just one of 19 states in which
the Darwinism vs. Intelligent Design contest is being fought.
Emotions have been running high, as they often do when the state takes
sides in a clash of fundamental values and beliefs. ...
Once there was a solid consensus about how public schools should be
run. ... But as [recent] battles ... make clear, that day is past.
From issues of sexuality and religion to the broad themes of US
history and politics, public opinion is fractured. ...
No longer is there a common understanding of the mission
of public education. To the extent that one camp's vision prevails,
parents in the opposing camp are embittered. And there is no prospect
that this will change -- not as long as the government remains in
charge of educating American children.
Which is why it's time to put an end to government control of the

A Real Sex Education Should Be Based in the Humanities
by Terrence Moore, Ph.D., May 2004.
"But what is love, and who is capable of love? Young people are not
thought to be capable of driving until they are sixteen. They cannot
vote until age eighteen and cannot buy alcohol legally until
twenty-one. When do they become capable of loving another human being
and living up to the responsibilities that come with love? Of this,
our sexual educators have little to say. Fortunately, history and the
classics have a great deal to say. ...
The humanities offer compelling and lasting lessons and examples of
the good, the beautiful, and the true."
A Return to Chivalry?
by Terrence Moore, Ph.D., August 2001.
"Currently, there is a great cultural battle being waged on every

battle is being lost, but the tide has perhaps turned."

"One must not assume that an understanding of science is present
in those who borrow its language."
-- Louis Pasteur
"Biographical history, as taught in our public schools, is still largely a history of
boneheads: ridiculous kings and queens, paranoid political leaders, compulsive voyagers,
ignorant generals -- the flotsam and jetsam of historical currents. The men who radically
altered history, the great scientists and mathematicians, are seldom mentioned, if at all."
-- Martin Gardner
"I can appreciate the beauty of a flower. But at the same time,
I see much more in the flower [than my artist friend]. I can imagine
the cells inside, which also have a beauty. There's beauty not just at the
dimension of one centimeter; there's also beauty at smaller dimension.
... There are all kinds of interesting questions that come from a knowledge
of science, which only adds to the excitement and mystery and awe of a flower.
It only adds, I don't understand how it subtracts."

"Mathematics is the door and key to the sciences"
-- Roger Bacon, 1267
"If it cannot be expressed in figures, it is not science, it is opinion."
