We Need to Rewrite the Textbook on How to Teach Teachers
A report from the National Council on Teacher Quality has found teacher-training textbooks aren't based in evidence.
We need to completely rewrite the textbooks on how to teach teachers. That’s according to a new report just published by the National Council on Teacher Quality. The report describes a vast and severe failure of teacher-training courses and the textbooks that accompany them to convey evidence-based practices; while delivering unsupported anecdotal evidence and well-debunked myths in spades. The report is accompanied by a letter of support signed by an assortment of professors of psychology and learning sciences from universities around the world.
The report finds that out of 48 texts used in teacher-training programs none accurately described fundamental evidence-based teaching strategies comprehensively. Only 15 percent had more than a single page devoted to evidence-based practices; the remainder contained either zero or only a few sentences on methods that have been backed up by the decades of scientific findings that exist in the field of educational psychology.
Missing from these textbooks were detailed explanations of six core strategies that have been found to be backed by evidence, which every teacher should know and use. The strategies aren't new; they were identified by the Institute of Education Sciences, the research arm of the U.S. Department of Education, as being the most effective techniques in all classrooms regardless of age or subject in guidance released in 2007.
The report didn’t just closely examine textbooks, but also delved into evaluations of entire courses, finding that “aspiring teachers are not being taught — in textbooks or in their coursework and training — the foundational knowledge about cognitive strategies that can help ensure children will learn."
When the six core evidence-based methods were addressed in the 219 courses the researchers assessed, the explanations were severely inadequate, failing to communicate important facts such as the evidence on how spacing learning across time has an incredibly powerful impact on information retention.
None of the textbooks explained that rather than showing how to complete a problem and then letting students get on with it, teaching is far more effective when a teacher repeatedly alternates between allowing the class to solve a problem themselves and then working together through a solution.
The researchers did not mince their words in their summation of the failure of publishers and educators in the discipline of teacher training:
“A textbook purporting to cover instructional design to maximize learning and retention that fails to cover these six strategies is no less remiss than a botany textbook that fails to address photosynthesis or an American government text devoid of a discussion of the three branches of government.”
The report also slammed textbooks and courses for discussing at great length unsupported theories such as “learning styles,” the debunked idea that each child is a visual, kinetic or auditory learner; and that teaching a child in their preferred learning style is more effective. In reality, all children require varied styles of teaching chosen based on the information being taught at the time rather than the child’s personal preference.
The six winning strategies that are neglected among the textbooks:
The researchers found that in more than half of the texts, none of the fundamental teaching strategies were even explained:
In the rare cases where the strategies were covered, they were often incompletely and incorrectly explained. In one example, a textbook that mentions a core principle — distributed practice — fails to bother to discuss appropriate lengths of gaps between exposures, despite a wealth of evidence in this area. Differing lengths of intervals between teaching result in enormously varied degrees of effectiveness; “appropriate intervals are generally much longer than anyone would guess — weeks or months, rather than days” the researchers explain.
“Looking for the six strategies in these textbooks is akin to looking for six needles in a haystack.”
Ultimately the study found that amongst pages of references “of relatively little merit” listed at the back of textbooks, each textbook barely referenced a single seminal study. If each of the 48 textbooks were to mention the six strategies once there would be a combined total of 288 references, but the total across all of the textbooks was only 118. I find this result deeply worrying because it indicates teachers are being taught by teacher-training textbooks to accept and promote claims without even providing the means to check that information against an original source. The act of effectively searching widely for evidence and then citing the source of that evidence is a crucial part of both teaching and learning, but it appears teacher-training textbooks are failing to do this on a grand scale.
If the conclusions of this damning report are to be believed, then more may be learned from what we have learned from decades of scientific research into education in this short report than in hundreds of pages of teacher training textbooks. Trainee or not, it’s certainly a report every single teacher — and learner for that matter — should read.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.
Is this proof of a dramatic shift?

Dramatic and misleading

The situation today: CNN pushed back to the edges of the country.
Over the course of no more than a decade, America has radically switched favorites when it comes to cable news networks. As this sequence of maps showing TMAs (Television Market Areas) suggests, CNN is out, Fox News is in.
The maps are certainly dramatic, but also a bit misleading. They nevertheless provide some insight into the state of journalism and the public's attitudes toward the press in the US.
Let's zoom in:
- It's 2008, on the eve of the Obama Era. CNN (blue) dominates the cable news landscape across America. Fox News (red) is an upstart (°1996) with a few regional bastions in the South.
- By 2010, Fox News has broken out of its southern heartland, colonizing markets in the Midwest and the Northwest — and even northern Maine and southern Alaska.
- Two years later, Fox News has lost those two outliers, but has filled up in the middle: it now boasts two large, contiguous blocks in the southeast and northwest, almost touching.
- In 2014, Fox News seems past its prime. The northwestern block has shrunk, the southeastern one has fragmented.
- Energised by Trump's 2016 presidential campaign, Fox News is back with a vengeance. Not only have Maine and Alaska gone from entirely blue to entirely red, so has most of the rest of the U.S. Fox News has plugged the Nebraska Gap: it's no longer possible to walk from coast to coast across CNN territory.
- By 2018, the fortunes from a decade earlier have almost reversed. Fox News rules the roost. CNN clings on to the Pacific Coast, New Mexico, Minnesota and parts of the Northeast — plus a smattering of metropolitan areas in the South and Midwest.

This sequence of maps, showing America turning from blue to red, elicited strong reactions on the Reddit forum where it was published last week. For some, the takeover by Fox News illustrates the demise of all that's good and fair about news journalism. Among the comments?
- "The end is near."
- "The idiocracy grows."
- "(It's) like a spreading disease."
- "One of the more frightening maps I've seen."
- "LOL that's what happens when you're fake news!"
- "CNN went down the toilet on quality."
- "A Minecraft YouTuber could beat CNN's numbers."
- "CNN has become more like a high-school production of a news show."
Not a few find fault with both channels, even if not always to the same degree:
- "That anybody considers either of those networks good news sources is troubling."
- "Both leave you understanding less rather than more."
- "This is what happens when you spout bullsh-- for two years straight. People find an alternative — even if it's just different bullsh--."
- "CNN is sh-- but it's nowhere close to the outright bullsh-- and baseless propaganda Fox News spews."
"Old people learning to Google"

CNN vs. Fox News search terms (200!-2018)
But what do the maps actually show? Created by SICResearch, they do show a huge evolution, but not of both cable news networks' audience size (i.e. Nielsen ratings). The dramatic shift is one in Google search trends. In other words, it shows how often people type in "CNN" or "Fox News" when surfing the web. And that does not necessarily reflect the relative popularity of both networks. As some commenters suggest:
- "I can't remember the last time that I've searched for a news channel on Google. Is it really that difficult for people to type 'cnn.com'?"
- "More than anything else, these maps show smart phone proliferation (among older people) more than anything else."
- "This is a map of how old people and rural areas have learned to use Google in the last decade."
- "This is basically a map of people who don't understand how the internet works, and it's no surprise that it leans conservative."
A visual image as strong as this map sequence looks designed to elicit a vehement response — and its lack of context offers viewers little new information to challenge their preconceptions. Like the news itself, cartography pretends to be objective, but always has an agenda of its own, even if just by the selection of its topics.
The trick is not to despair of maps (or news) but to get a good sense of the parameters that are in play. And, as is often the case (with both maps and news), what's left out is at least as significant as what's actually shown.
One important point: while Fox News is the sole major purveyor of news and opinion with a conservative/right-wing slant, CNN has more competition in the center/left part of the spectrum, notably from MSNBC.
Another: the average age of cable news viewers — whether they watch CNN or Fox News — is in the mid-60s. As a result of a shift in generational habits, TV viewing is down across the board. Younger people are more comfortable with a "cafeteria" approach to their news menu, selecting alternative and online sources for their information.
It should also be noted, however, that Fox News, according to Harvard's Nieman Lab, dominates Facebook when it comes to engagement among news outlets.

For the record, here are the Nielsen ratings for average daily viewer total for the three main cable news networks, for 2018 (compared to 2017):
- Fox News: 1,425,000 (-5%)
- MSNBC: 994,000 (+12%)
- CNN: 706,000 (-9%)
And according to this recent overview, the top 50 of the most popular websites in the U.S. includes cnn.com in 28th place, and foxnews.com in... 27th place.The top 5, in descending order, consists of google.com, youtube.com, facebook.com, amazon.com and yahoo.com — the latter being the highest-placed website in the News and Media category.
