Science Teaching. What's wrong with it?

Mobile phone risks clouded in science

People are confused and apathetic about mobile phone radiation, and the situation can be partly traced back to science classrooms, says Clare Christensen, a recent PhD graduate from Queensland University of Technology.

"Science is supposed to be about certainty - at least that's what they tell us in school - but people are seeing media reports with scientists disagreeing over things such as the possible health risks with mobile phones,'' Dr Christensen said.

"There is a cynicism that develops when people see scientists as having different 'opinions', but of course it's not about opinion. Scientists are always disagreeing - always have and probably always will."

Dr Christensen talked with people aged 18 to 26 about their mobile phones and how they saw the possible risks in the light of contradictory news reports.

In focus group discussions, they initially talked about how useful mobile phones were but this changed when they were shown a media report on two Australian studies.

The first found double the rate of cancer in mice exposed to mobile phone radiation and the second found no change in cancer rates among exposed mice.

"Social networking and peer pressure issues outweighed health issues because the scientific evidence is seen as contradictory and uncertain," Dr Christensen said.

"The news media are not giving us very much information on how the research is set up and why the findings from one study differ markedly from another.

"At the same time, it seems people aren't in a hurry to find out for themselves. They could do an internet search to gather information, but they simply don't. The search would not yield a definitive answer but they would at least be more aware of the risks."

Dr Christensen said a greater emphasis on discussion and realistic inquiry work in schools would likely lead to a genuine interest in the science of issues such as mobile phone radiation, global warming, cloning, medical procedures and genetically modified foods.

"Very few people I spoke to had discussed contemporary issues of science in the classroom,'' she said.

"The trouble is, we're not conditioned to discuss science at school.
It's an authoritarian model with this over-riding preoccupation with getting the right answers."

My kids' senior science book was a disgrace. It stared by looking at scientific method in all its boring detail. They were both put off science from day one.

I started my love of science by blowing up things and my teacher crushing a tin can right in front of me! Wow! How did he do that with a Bunsen burner and a bit of water?!

Star wars exhibit has come to Sydney Power House Museum of technology.
Wow! off to see that next week!-MA

The problem with scientists diagreeing is that they are always labeled as scientists and not nuroscientist or biologist, or titles like that. Yes I can get a bunch on scientists together and ask them about radiation, but it depends on which type of scientists I have. I mean everyone who has a doctor title isnt a medical doctor you can get a doctorate in most fields. Plus with something like cellular radiation you can't just bring one type of scientist in and ask his opinion. You need someone who is familiar with biology, specifically the head. You need someone who knows electronics and radiation. Then they might give you a better answer.
Celluar radiation isn't enough to harm you at all unless you tape a phone to your head and wear it 24/7 for a few years, while talking to people on it continuously without a break. Then you might notice some changes. The mass media directs us away from real issues and presents us with this crap to keep us from learning. There are tons of issues happening around the world and the media publishes non of them.

there might be some effects that are occuring without the symptoms, only testing over time will give us the answers.Opinions do not dictate, but facts and results give us the information needed. Here is a couple of links you may be interested in

From Sarsheild
What many cell phone users may not know is that cell phones send electromagnetic waves into users' brains. In fact, every cell phone model sold in the United States has a specific measurement of how much microwave energy from the phone can penetrate the brain. Depending on how close the cell phone antenna is to the head, as much as 60 percent of the microwave radiation is absorbed by and actually penetrates the area around the head, some reaching an inch to an inch-and-a-half into the brain.

"This is the first generation that has put relatively high-powered transmitters against the head, day after day," says Dr. Ross Adey, who has worked for industry and government for decades studying microwave radiation, and is one of the most respected scientists in the field. Tests conducted by the ABC show 20/20 have found that some of the country's most popular cell phones can - depending on how they're held - exceed the radiation limit. 20/20 reported that government-testing guidelines are so vague that a phone can pass the Federal Communications Commission's requirements when tested in one position and exceed those maximum levels when held in another position.

Experts say it's particularly hard to predict the long-term impact of a product that's just two decades old, especially since most of the 95 million Americans who now have cell phones began using them in the past five years.

from wiki
Mobile phone radiation and health concerns have been raised, especially following the enormous increase in the use of wireless mobile telephony throughout the world (as of August 2005[update], there were more than 2 billion users worldwide). Mobile phones use electromagnetic radiation in the microwave range, and somebelieve this may be harmful to human health. These concerns have induced a large body of research (both epidemiological and experimental, in non-human animals and in humans). Concerns about effects on health have also been raised regarding other digital wireless systems, such as data communication networks.

The World Health Organization, based upon the consensus view of the scientific and medical communities, states that health effects (e.g. headaches) are very unlikely to be caused by cellular phones or their base stations, and expects to make recommendations about mobile phones in October 2009.

However, some national radiation advisory authorities, including those of Austria, France, Germany, and Sweden recommended to their citizens measures to minimize exposure. Examples of the recommendations are:

Use hands-free to decrease the radiation to the head.
Keep the mobile phone away from the body.
Do not telephone in a car without an external antenna.

I don't think that is an excuse any more.
Although most magazines seem to be written for 8 YOs with a film/rock star obsession.
With the web you can choose what you want to read and the newsletters and alerts you want to get.

Most newspapers and magazines that are written by "news" companies write them so that someone with only an 8th grade education can read them. Therby targeting the lowest common denominator.

What I think I meant was that the media finds stories that will cause enough of an uproar to get them better ratings. They find hot button issues and explain them in such a one sided, simplistic, way without too much information. I belive it is called a "soundbyte".
Everyone uses cellphones and most people know practically nothing about radiation except that it can kill you or cause cancer. They do not, however, know how or why or in what dose. Which makes it a good topic to scare the masses enough to want to know more, but not much more.

Science and knowledge requires expension of labor; and labor requires compensation. We will learn when it is necessary and cheap.

[stereologist]

Difficult problems such as determining the effects of EM on biological tissue require lots of work as lawcat points out. On the other hand Theory 5 points out that news organizations will find someone suing because they have a cancer shaped like a cellphone and write this up as if this is significant. As Michaelangelica points out it is possible to find good information, but it takes effort.

Look at claims. How many people are in the study? Case studies of 1 patient, ie the guy with the cellphone shaped tumor are worthless. The study with 5 is not interesting. Get a few hundred talkaholics in a study and now there is some merit in reading about the work.

Bingo

I think it starts with teachers never being accountable to anyone. Our model does not favor truth. As turtle said in another thread, if you are right about something and the teacher is wrong, the system makes it difficult (not impossible, but beyond what most people will do) to do anything about it.

The result is that the truth is deferred to social structure. If the social structure is uncertain, people simply withhold judgment.

That is just crook teaching.
Education is to "lead out" the talents within, not to impose some authoritarian view.

Society does impose it's world view even in Science, sometimes this is resistance to change, or protecting my patch or ego; at other times it is pathological.

Not quite appropriate, but close, any excuse for a XML comic:
