Op-Ed: Lack of Critical Thinking by Students and the Media. Example #34523195323

A recent piece on a local news station depicted the supposed problem of “milky” water coming from a water fountain at a local high school.

Indeed, a semi-viral video was taken that shows what appears to be the suspect water with some kind of white substance, flowing into someone’s receiving hands.

“This is what y’all are drinking?” was the phrase embedded in the video.

What could it be?

Anyone that has lived any amount of time in this city knows that what the students were actually looking at was a situation where tiny bubbles are released when the pressure or temperature changes inside a water system, not unlike what happens when a bottle of soda is opened. It is the public tap water version of carbonation.

Those billions of tiny bubbles, in the right lighting, make the water appear to temporarily look whitish.

The reporter then went on to ask students if the taste of the water was different (it wasn’t) and, to his credit, even linked to a US Geological Survey webpage that explained the phenomenon, which occurs so often in El Paso that it can’t be considered phenomenal.

However, to students who grow up with prepackaged water from a plastic bottle, the appearance of anything that is not “perfect” must mean something nefarious is happening. (All bananas must be yellow, all tomatoes must be red, and anything off the norm must be bad is what these students (and reporter) are saying here and what they have been taught by society to accept as truth.)

Conclusion of the story: It wasn’t water laced with Round Up, milk, or some nefarious carcinogen. It was tiny, harmless, bubbles.

After thinking about that piece for a while, it occurred to me that while this was a non-story that somehow ended up on the air, the reporter did not ask the students any basic questions, did not have the person that created the video on air, did not look critically at the video itself (does this happen anywhere else), and had to take a “something must be wrong” attitude in order to even do the story.

Why didn’t the reporter ask for a sample of the suspect water?

Why wouldn’t the student who created the video want to provide further evidence?

Non-critical reporting is not taught in journalism, but seems to be par for the course in El Chuco.

Concurrently, the students that created the video demonstrated a total lack of critical thinking. Did the water look like that after 10 seconds? 20 seconds? Half a minute?

Consider that this event took place at a high school. High schools have science departments, including chemistry classes. Most modern high schools have equipment for testing water, some even equipped with sensors that can detect dissolved and precipitate matter in water.

Why didn’t these students think to first take a sample of the water to one of the Chemistry teachers at the campus? There are 22 science teachers at the campus, including AP Chemistry.

Surely one teacher could have easily given the students a beaker, taken a sample, and tested it, or better yet, have the students test it. If there was no problem, case dismissed. If they found an irregularity, THEN report it to the campus administration. None of that seems to have been done in this case.

Every moment is a teaching moment if we make it so or teach students that way.

Probably, teachers weren’t even aware of the student concerns in the first place, which bring to mind the question “Why aren’t students trained to seek ways to answer their questions first?” That is what the scientific method is all about.

In this case, these particular students did not seem to remember a single lesson taught on problem solving.

Students, who are always accused by adults of spending too much time on the internet, apparently spent no time looking up what might have caused “milky water” in the first place.

A simple Google search on “What causes water to look milky?” brings up hundreds of websites in less than a second.

Why wasn’t this done by the students? Why didn’t the report ask them?

To me, this is a sad commentary on the critical need to teach students basic problem solving, not about “milky water” at one high school.

Op-Ed: Without Critical Thinking, We are Doomed

Perhaps you have heard of a group of people that believe the earth in which we inhabit is indeed flat, like a coin, and not a sphere.

They are called the “Flat Earthers” and deny all of the science that we have learned since Eratosthenes of Cyrene first calculated the circumference of our celestial sphere 200 years before the Common Era (amazingly enough, using only simple trigonometry, he was off by only a few hundred miles, all calculated without ever leaving Egypt).

The earth was assumed to be a sphere long before Columbus sailed the ocean blue ( a common elementary school misconception that he was trying to prove the world was round to Queen Isabella.) It didn’t take someone with a PhD in astronomy to understand that as a ship sailed away from port, it not only got smaller, but also the masts got lower and lower on the horizon until the tallest mast disappeared completely from view, something that would only happen on a sphere.

On a flat earth, the masts would always remain in view until the ship was too far away to be seen. Never mind that all the other planets in our solar system, our moon, our sun and even the newest extrasolar system planets we have detected are also spheres. Never mind that hundreds of people have actually circled the sphere, some for months at a time, have taken pictures and video, and have returned safely without an iota of evidence that the earth is shaped in any shape other than a slightly elongated sphere.

Anyone that has watched a sunset understands that the earth is not flat. All the evidence points to it. All the science clearly shows it. Even a casual non scientist can look at the evidence such as an eclipse with solar and lunar, and understand.

Flat earth believers can believe all they want, but no matter how hard they believe, no matter how much they wish it were true, the facts are clear: The earth is spheroid. Facts do not care about your beliefs.. No matter how much they want it to be a fact, it will never be a fact.

We are currently living in a time when it seems almost fashionable to take the contrarian view of things, ignore all facts and obvious evidence. And while it might be a harmless diversion to chuckle at the flat earthers, there is a more insidious problem afoot that they typify: Denying facts and creating an alternative reality.

There are much more important issues right now that have their own “flat earth” type believers. And those issues are much more serious.

Global Climate change. The evidence both scientific and observed, is overwhelming, so much so that in some places right now, such as Miami Beach Florida, sea level rise has cause near panic by real estate developers. Farmers are seeing crop seasons and temperatures being altered, not for a year or two, but now for decades.

Some crops are no longer viable in places where they had been grown for hundreds of years because the local climate is no longer able to

sustain them. Yet there are those that continue to deny that change is even happening. “There cannot any kind of global warming because it snowed here last week.”

Vaccinating children against deadly diseases causes autism. There is overwhelming evidence both scientific and observable, that vaccines do NOT cause autism, and DO prevent dreadful, sometimes deadly diseases.

Yet there are now a growing number of parents, almost 15% of American parents, that would rather risk their children’s lives and the lives of children around their’s all because of someone they listen to that does not look critically at the issue but rather emotionally. “My child has autism. My child got a MMR vaccine. Therefore vaccines cause autism.”

These are just two examples of topics where a large number of Americans are refusing to look critically at issues. There are hundred of others from benign (ancient aliens mated with our ancient ancestors and helped build the pyramids) to the deadly (there are entire religions out to “get us).

Some of this easy-to-fall-for belief system has to do with the ready availability of information on the internet, where almost all sources of information are equal to each other. An amateur political commentator with no training, a webcam , a YouTube channel, and an agenda, who used to be a used car salesman has as much gravitas as a person that has dedicated her career to deeply understanding an issue.

A website that looks professionally done but was written by an angry blogger with no background other than a deeply held belief of some kind, has as much impact as one that was written by a person that has much background but a boring website just filled with vetted research. On top of that, people gravitate to an echo chamber of similar sites. That is why the people that watch Fox News listen to Rush Limbaugh, read American Spectator, and ignore NPR and the New York Times and dismiss CNN as “fake news.”

Sadly, I believe we must blame our past and current education system for this very real phenomenon of believing in something and completely ignoring anything that might alter that preconditioned belief. We obviously, as a country, are dropping the ball on having adults think critically about issues, vet sources and look for alternative explanations.

When someone with no background can make an argument believed by millions that we have never landed on the moon, despite the fact we actually have hundreds of pounds of moon rocks, spent billions of dollars, and actually have living men that WALKED ON HTE MOON and left instruments that are still there, then we are obviously leaving off a major piece of the education pie.

And while we are starting to bring critical thinking back to the fore with innovative teaching techniques, those are too few and too far between and in some cases, too late. The generation that is now making decisions has demonstrated time and again that they completely missed the critical thinking boat in school. Yet, they will also be the first to say that “when I was in school” things were better. No they were not. By almost any metric, education is better now than it has ever been in the US.

The time has come to right the ship. Make critical thinking one of the core subject areas. Embed the basics of critical thinking into all subject areas. Don’t give critical thinking lip service in the curriculum. Make it a major part. Test critical thinking skills just as we test Math and Reading skills.

If we don’t then we have no one but ourselves to blame when we devolve into a country of angry citizens that think their opinion is the one true only opinion, and that facts are just things that, like statistics, can be made to say whatever you want them to.
