Today’s Focus on STEM Education Is Missing A Crucial Point
A student in a contemplative pose.
I once saw a fascinating TED talk on 3D printing. As I watched the presenter discuss the custom fabrication, not of plastic gears or figurines, but of living, implantable kidneys, I thought I was finally living in the world of Star Trek, and I experienced a flush of that eager, expectant enthusiasm I felt as a child looking toward the future. I looked at my current career and felt a rejuvenation of my commitment to teach young people the power of science.
The well-rounded education of human beings needs to include lessons learned both from a study of the physical world, and from a study of humanity.
Whether we are teachers or not, those of us who admire technology and innovation, and who wish to support progress, usually embrace the importance of educating the next generation of scientists and inventors. Growing a healthy technological civilization takes a lot of work, skill, and wisdom, and its continued health depends on future generations of competent thinkers. Thus, we may find it encouraging that there is currently an abundance of interest in STEM– the common acronym for the study of science, technology, engineering, and math.
But education is as challenging an endeavor as science itself. Educating youth--if we want to do it right--requires as much thought, work, and expertise as discovering a cure or pioneering regenerative medicine. Before we give our money, time, or support to any particular school or policy, let's give some thought to the details of the educational process.
A Well-Balanced Diet
For one thing, STEM education cannot stand in isolation. The well-rounded education of human beings needs to include lessons learned both from a study of the physical world, and from a study of humanity. This is especially true for the basic education of children, but it is true even for college students. And even for those in science and engineering, there are important lessons to be learned from the study of history, literature, and art.
Scientists have their own emotions and values, and also need financial support. The fruits of their labor ultimately benefit other people. How are we all to function together in our division-of-labor society, without some knowledge of the way societies work? How are we to fully thrive and enjoy life, without some understanding of ourselves, our motives, our moral values, and our relationships to others? STEM education needs the humanities as a partner. That flourishing civilization we dream of requires both technical competence and informed life-choices.
Think for Yourself (Even in Science)
Perhaps even more important than what is taught, is the subject of how things are taught. We want our children to learn the skill of thinking independently, but even in the sciences, we often fail completely to demonstrate how. Instead of teaching science as a thinking process, we indoctrinate, using the grand discoveries of the great scientists as our sacred texts. But consider the words of Isaac Newton himself, regarding rote learning:
A Vulgar Mechanick can practice what he has been taught or seen done, but if he is in an error he knows not how to find it out and correct it, and if you put him out of his road he is at a stand. Whereas he that is able to reason nimbly and judiciously about figure, force, and motion, is never at rest till he gets over every rub.
What's the point of all this formal schooling in the first place? Is it, as many of the proponents of STEM education might argue, to train students for a "good" career?
If our goal is to help students "reason nimbly" about the world around them, as the great scientists themselves did, are we succeeding? When we "teach" middle school students about DNA or cellular respiration by presenting as our only supporting evidence cartoon pictures, are we showing students a process of discovery based on evidence and hard work? Or are we just training them to memorize and repeat what the authorities say?
A useful education needs to give students the skill of following a line of reasoning, of asking rational questions, and of chewing things through in their minds--even if we regard the material as beyond question. Besides feeding students a well-balanced diet of knowledge, healthy schooling needs to teach them to digest this information thoroughly.
Thinking Training
Now step back for a moment and think about the purpose of education. What's the point of all this formal schooling in the first place? Is it, as many of the proponents of STEM education might argue, to train students for a "good" career? That view may have some validity for young adults, who are beginning to choose electives in favored subjects, and have started to choose a direction for their career.
But for the basic education of children, this way of thinking is presumptuous and disastrous. I would argue that the central purpose of a basic education is not to teach children how to perform this or that particular skill, but simply to teach them to think clearly. We should not be aiming to provide job training, but thinking training. We should be helping children learn how to "reason nimbly" about the world around them, and breathing life into their thinking processes, by which they will grapple with the events and circumstances of their lives.
So as we admire innovation, dream of a wonderful future, and attempt to nurture the next generation of scientists and engineers, instead of obsessing over STEM education, let us focus on rational education. Let's worry about showing children how to think--about all the important things in life. Let's give them the basic facts of human existence -- physical and humanitarian -- and show them how to fluently and logically understand them.
Some students will become the next generation of creators, and some will follow other careers, but together -- if they are educated properly -- they will continue to grow their inheritance, and to keep our civilization healthy and flourishing, in body and in mind.
The upcoming vaccine is changing the way we look at treating one of the country’s deadliest cancers.
Last week, researchers at the University of Oxford announced that they have received funding to create a brand new way of preventing ovarian cancer: A vaccine. The vaccine, known as OvarianVax, will teach the immune system to recognize and destroy mutated cells—one of the earliest indicators of ovarian cancer.
Understanding Ovarian Cancer
Despite advancements in medical research and treatment protocols over the last few decades, ovarian cancer still poses a significant threat to women’s health. In the United States alone, more than 12,0000 women die of ovarian cancer each year, and only about half of women diagnosed with ovarian cancer survive five or more years past diagnosis. Unlike cervical cancer, there is no routine screening for ovarian cancer, so it often goes undetected until it has reached advanced stages. Additionally, the primary symptoms of ovarian cancer—frequent urination, bloating, loss of appetite, and abdominal pain—can often be mistaken for other non-cancerous conditions, delaying treatment.
An American woman has roughly a one percent chance of developing ovarian cancer throughout her lifetime. However, these odds increase significantly if she has inherited mutations in the BRCA1 or BRCA2 genes. Women who carry these mutations face a 46% lifetime risk for ovarian and breast cancers.
An Unlikely Solution
To address this escalating health concern, the organization Cancer Research UK has invested £600,000 over the next three years in research aimed at creating a vaccine, which would destroy cancerous cells before they have a chance to develop any further.
Researchers at the University of Oxford are at the forefront of this initiative. With funding from Cancer Research UK, scientists will use tissue samples from the ovaries and fallopian tubes of patients currently battling ovarian cancer. Using these samples, University of Oxford scientists will create a vaccine to recognize certain proteins on the surface of ovarian cancer cells known as tumor-associated antigens. The vaccine will then train that person’s immune system to recognize the cancer markers and destroy them.
The next step
Once developed, the vaccine will first be tested in patients with the disease, to see if their ovarian tumors will shrink or disappear. Then, the vaccine will be tested in women with the BRCA1 or BRCA2 mutations as well as women in the general population without genetic mutations, to see whether the vaccine can prevent the cancer altogether.
While the vaccine still has “a long way to go,” according to Professor Ahmed Ahmed, Director of Oxford University’s ovarian cancer cell laboratory, he is “optimistic” about the results.
“We need better strategies to prevent ovarian cancer,” said Ahmed in a press release from the University of Oxford. “Currently, women with BRCA1/2 mutations are offered surgery which prevents cancer but robs them of the chance to have children afterward.
Teaching the immune system to recognize the very early signs of cancer is a tough challenge. But we now have highly sophisticated tools which give us real insights into how the immune system recognizes ovarian cancer. OvarianVax could offer the solution.”
How sharing, hearing, and remembering positive stories can help shape our brains for the better
Across cultures and through millennia, human beings have always told stories. Whether it’s a group of boy scouts around a campfire sharing ghost stories or the paleolithic Cro-Magnons etching pictures of bison on cave walls, researchers believe that storytelling has been universal to human beings since the development of language.
But storytelling was more than just a way for our ancestors to pass the time. Researchers believe that storytelling served an important evolutionary purpose, helping humans learn empathy, share important information (such as where predators were or what berries were safe to eat), as well as strengthen social bonds. Quite literally, storytelling has made it possible for the human race to survive.
Today, neuroscientists are discovering that storytelling is just as important now as it was millions of years ago. Particularly in sharing positive stories, humans can more easily form relational bonds, develop a more flexible perspective, and actually grow new brain circuitry that helps us survive. Here’s how.
How sharing stories positively impacts the brain
When human beings share stories, it increases the levels of certain neurochemicals in the brain, neuroscientists have found. In a 2021 study published in Proceedings of the National Academy of Sciences (PNAS), Swedish researchers found that simply hearing a story could make hospitalized children feel better, compared to other hospitalized children who played a riddle game for the same amount of time. In their research, children in the intensive care unit who heard stories for just 30 minutes had higher levels of oxytocin, a hormone that promotes positive feelings and is linked to relaxation, trust, social connectedness, and overall psychological stability. Furthermore, the same children showed lower levels of cortisol, a hormone associated with stress. Afterward, the group of children who heard stories tended to describe their hospital experiences more positively, and even reported lower levels of pain.
Annie Brewster, MD, knows the positive effect of storytelling from personal experience. An assistant professor at Harvard Medical School and the author of The Healing Power of Storytelling: Using Personal Narrative to Navigate Illness, Trauma, and Loss, Brewster started sharing her personal experience with chronic illness after being diagnosed with multiple sclerosis in 2001. In doing so, Brewster says it has enabled her to accept her diagnosis and integrate it into her identity. Brewster believes so much in the power of hearing and sharing stories that in 2013 she founded Health Story Collaborative, a forum for others to share their mental and physical health challenges.“I wanted to hear stories of people who had found ways to move forward in positive ways, in spite of health challenges,” Brewster said. In doing so, Brewster believes people with chronic conditions can “move closer to self-acceptance and self-love.”
While hearing and sharing positive stories has been shown to increase oxytocin and other “feel good” chemicals, simply remembering a positive story has an effect on our brains as well. Mark Hoelterhoff, PhD, a lecturer in clinical psychology at the University of Edinburgh, recalling and “savoring” a positive story, thought, or feedback “begins to create new brain circuitry—a new neural network that’s geared toward looking for the positive,” he says. Over time, other research shows, savoring positive stories or thoughts can literally change the shape of your brain, hard-wiring someone to see things in a more positive light.How stories can change your behavior
In 2009, Paul Zak, PhD, a neuroscientist and professor at Claremont Graduate University, set out to measure how storytelling can actually change human behavior for the better. In his study, Zak wanted to measure the behavioral effects of oxytocin, and did this by showing test subjects two short video clips designed to elicit an emotional response.
In the first video they showed the study participants, a father spoke to the camera about his two-year-old son, Ben, who had been diagnosed with terminal brain cancer. The father told the audience that he struggled to connect with and enjoy Ben, as Ben had only a few months left to live. In the end, the father finds the strength to stay emotionally connected to his son until he dies.
The second video clip, however, was much less emotional. In that clip, the same father and son are shown spending the day at the zoo. Ben is only suggested to have cancer (he is bald from chemotherapy and referred to as a ‘miracle’, but the cancer isn’t mentioned directly). The second story lacked the dramatic narrative arc of the first video.
Zak’s team took blood before and after the participants watched one of the two videos and found that the first story increased the viewers’ cortisol and oxytocin, suggesting that they felt distress over the boy’s diagnosis and empathy toward the boy and his father. The second narrative, however, didn’t increase oxytocin or cortisol at all.
But Zak took the experiment a step further. After the movie clips, his team gave the study participants a chance to share money with a stranger in the lab. The participants who had an increase in cortisol and oxytocin were more likely to donate money generously. The participants who had increased cortisol and oxytocin were also more likely to donate money to a charity that works with children who are ill. Zak also found that the amount of oxytocin that was released was correlated with how much money people felt comfortable giving—in other words, the more oxytocin that was released, the more generous they felt, and the more money they donated.
How storytelling strengthens our bond with others
Sharing, hearing, and remembering stories can be a powerful tool for social change–not only in the way it changes our brain and our behavior, but also because it can positively affect our relationships with other people
Emotional stimulation from telling stories, writes Zak, is the foundation for empathy, and empathy strengthens our relationships with other people. “By knowing someone’s story—where they come from, what they do, and who you might know in common—relationships with strangers are formed.”
But why are these relationships important for humanity? Because human beings can use storytelling to build empathy and form relationships, it enables them to “engage in the kinds of large-scale cooperation that builds massive bridges and sends humans into space,” says Zak.
Storytelling, Zak found, and the oxytocin release that follows, also makes people more sensitive to social cues. This sensitivity not only motivates us to form relationships, but also to engage with other people and offer help, particularly if the other person seems to need help.
But as Zak found in his experiments, the type of storytelling matters when it comes to affecting relationships. Where Zak found that storytelling with a dramatic arc helps release oxytocin and cortisol, enabling people to feel more empathic and generous, other researchers have found that sharing happy stories allows for greater closeness between individuals and speakers. A group of Chinese researchers found that, compared to emotionally-neutral stories, happy stories were more “emotionally contagious.” Test subjects who heard happy stories had greater activation in certain areas of their brains, experienced more significant, positive changes in their mood, and felt a greater sense of closeness between themselves and the speaker.
“This finding suggests that when individuals are happy, they become less self-focused and then feel more intimate with others,” the authors of the study wrote. “Therefore, sharing happiness could strengthen interpersonal bonding.” The researchers went on to say that this could lead to developing better social networks, receiving more social support, and leading more successful social lives.
Since the start of the COVID pandemic, social isolation, loneliness, and resulting mental health issues have only gotten worse. In light of this, it’s safe to say that hearing, sharing, and remembering stories isn’t just something we can do for entertainment. Storytelling has always been central to the human experience, and now more than ever it’s become something crucial for our survival.
