Educators unveiled new guidelines on Tuesday that call for sweeping changes in the way science is taught in the United States

The guidelines, known as the Next Generation Science Standards, are the first broad national recommendations for science instruction since 1996. They were developed by a consortium of 26 state governments and several groups representing scientists and teachers.

The focus would be helping students become more intelligent science consumers by learning how scientific work is done: how ideas are developed and tested, what counts as strong or weak evidence, and how insights from many disciplines fit together into a coherent picture of the world.

Administration officials were still working Friday to finalize a list of options to present President Donald Trump concerning the next phase of national guidelines on coronavirus as he continues to push for reopening parts of the country.

Trump issued guidelines on social distancing meant to prevent the spread of novel coronavirus on March 16, but has said this week that he believes at least some Americans are ready to return to work amid a spike in jobless claims. The initial guidelines had a 15-day time frame, which will be reached early next week.

"We'll be sitting down on Monday or Tuesday, depending on which is best for everybody, and we'll be making that determination," Trump said, pointing to "brilliant" Dr. Anthony Fauci and Dr. Deborah Birx, and saying he'd hear out their options.

If you bothered to read the fine print when you created your Facebook account, you would have noticed just how much of yourself you were giving over to Mark Zuckerberg and his $340 billion social network.

In exchange for an admittedly magical level of connectivity, you were giving them your life as content — the right to run ads around video from your daughter’s basketball game; pictures from your off-the-chain birthday party, or an emotional note about your return to health after serious illness. You also gave them the right to use your information to help advertisers market to you

at the heart of the relationship is a level of trust and a waiving of privacy that Facebook requires from its users as it pursues its mission to “make the world more open and connected.”

If I were writing the dietary guidelines, I would give them a radical overhaul. I’d go so far as to radically overhaul the way we evaluate diet. Here’s why and how.

Lately, as scientists try, and fail, to reproduce results, all of science is taking a hard look at funding biases, statistical shenanigans and groupthink. All that criticism, and then some, applies to nutrition.

Prominent in the charge to change the way we do science is John Ioannidis, professor of health research and policy at Stanford University. In 2005, he published “Why Most Research Findings Are False” in the journal PLOS Medicin

Now expert groups are proposing less screening for prostate, breast and cervical cancer and have emphasized that screening comes with harms as well as benefits.

the influential United States Preventive Services Task Force, which evaluates evidence and publishes screening guidelines, said that women in their 40s do not appear to benefit from mammograms and that women ages 50 to 74 should consider having them every two years inst

Two recent clinical trials of prostate cancer screening cast doubt on whether many lives — or any — are saved. And it said that screening often leads to what can be disabling treatments for men whose cancer otherwise would never have harmed them. A new analysis of mammography concluded that while mammograms find cancer in 138,000 women each year, as many as 120,000 to 134,000 of those women either have cancers that are already lethal or have cancers that grow so slowly they do not need to be treated.

The leading US scientific organization, responding to concerns expressed by scientists and ethicists, has launched an ambitious initiative to recommend guidelines for new genetic technology that has the potential to create "designer babies."

The technology, called CRISPR-Cas9, allows scientists to edit virtually any gene they target

Although the embryos were not viable and could not have developed into babies, the announcement ignited an outcry from scientists warning that such a step, which could alter human genomes for generations, was just a matter of time.

Confirmation bias occurs when an individual looks for and uses the information to support their own ideas or beliefs. It also means that information not supporting their ideas or beliefs is disregarded. Confirmation bias often happens when we want certain ideas to be true. This leads individuals to stop gathering information when the retrieved evidence confirms their own viewpoints, which can lead to preconceived opinions (prejudices) that are not based on reason or factual knowledge. Individuals then pick out the bits of information that confirm their prejudices. Confirmation bias has a long history. In 1620, Francis Bacon described confirmation bias as: “Once a man’s understanding has settled on something (either because it is an accepted belief or because it pleases him), it draws everything else also to support and agree with it. And if it encounters a larger number of more powerful countervailing examples, it either fails to notice them, or disregards them, or makes fine distinctions to dismiss and reject them, and all this with much dangerous prejudice, to preserve the authority of its first Conceptions.” (Bacon 1620)

The impact of confirmation bias can be at the level of the individual all the way up to institution level. DuBroff showed that confirmation bias influenced expert guidelines on cholesterol and was highly prevalent when conflicts of interests were present (DuBroff 2017). He found that confirmation bias occurred due to a failure to incorporate evidence, or through misrepresentation of the evidence, which had the potential  to skew guideline recommendations

A University of New Mexico research team conducted a data analysis that has found that as a larger portion of the population gets vaccinated against COVID-19, it becomes economically advantageous to start relaxing social distancing measures and open businesses.

The study looked at data from four metropolitan statistical areas (MSAs) within the United States: Seattle, New York City, Los Angeles and Houston from January 21 to July 8, 2020. The four cities were chosen because they have had divergent trends with the virus (Seattle and New York City were early hotspots, while Los Angeles and Houston peaked in the summer).

"Our work is quantitative, so it can hopefully offer some evidence that shows the vaccines are going to allow us to loosen social distancing measures, including opening businesses," he said. "It provides a measure of hope as we go forward and increase the percentage of citizens who are vaccinated."

Ambiguity and vagueness in clinical practice guidelines reduce the likelihood of clinician adherence. They lead to inconsistent interpretation and, in turn, to inappropriate practice variation and medical errors.

Indeed, the very definition of “masculinity” is up for grabs

In 2019, the American Psychological Association published guidelines that took direct aim at what it called “traditional masculinity — marked by stoicism, competitiveness, dominance and aggression” — declaring it to be, “on the whole, harmful.”

Aside from “dominance,” a concept with precious few virtuous uses, the other aspects of traditional masculinity the A.P.A. cited have important roles to play. Competitiveness, aggression and stoicism surely have their abuses, but they also can be indispensable in the right contexts. Thus, part of the challenge isn’t so much rejecting those characteristics as it is channeling and shaping them for virtuous purposes.

The law, approved last March by Israel's legislating Knesset, requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months prior to a fashion shoot or show.

"This law is another step in the war against eating disorders,"

But critics of the law in this country say it and others like it—the Madrid Fashion Show's ban on women whose BMI is below 18, for example, and Milan's Fashion Week's ban on models with a BMI below 18.5—are misguided, focusing on weight instead of health.

For years, politicians wanting to block legislation on climate change have bolstered their arguments by pointing to the work of a handful of scientists who claim that greenhouse gases pose little risk to humanity.

One of the names they invoke most often is Wei-Hock Soon, known as Willie, a scientist at the Harvard-Smithsonian Center for Astrophysics who claims that variations in the sun’s energy can largely explain recent global warming.

He has accepted more than $1.2 million in money from the fossil-fuel industry over the last decade while failing to disclose that conflict of interest in most of his scientific papers. At least 11 papers he has published since 2008 omitted such a disclosure, and in at least eight of those cases, he appears to have violated ethical guidelines of the journals that published his work.

"A lot of the regulation of research ethics hinges on government supported research, and of course Facebook's research is not government supported, so they're not obligated by any laws or regulations to abide by the standards,"

many universities and research institutions and even for-profit companies use the Common Rule as a guideline anyway. It's voluntary. You could imagine if you were a drug company, you'd want to be able to say you'd done the research ethically because the backlash would be just huge otherwise."

The backlash, in this case, seems tied directly to the sense that Facebook manipulated people—used them as guinea pigs—without their knowledge, and in a setting where that kind of manipulation feels intimate

the last thing an elite education will teach you is its own inadequacy

I’m talking about the whole system in which these skirmishes play out. Not just the Ivy League and its peer institutions, but also the mechanisms that get you there in the first place: the private and affluent public “feeder” schools, the ever-growing parastructure of tutors and test-prep courses and enrichment programs, the whole admissions frenzy and everything that leads up to and away from it. The message, as always, is the medium. Before, after, and around the elite college classroom, a constellation of values is ceaselessly inculcated.

The first disadvantage of an elite education, as I learned in my kitchen that day, is that it makes you incapable of talking to people who aren’t like you. Elite schools pride themselves on their diversity, but that diversity is almost entirely a matter of ethnicity and race. With respect to class, these schools are largely—indeed increasingly—homogeneous. Visit any elite campus in our great nation and you can thrill to the heartwarming spectacle of the children of white businesspeople and professionals studying and playing alongside the children of black, Asian, and Latino businesspeople and professionals.

Now scientists have found a more noble purpose for the technique in a study that suggests deep-rooted biases about race and gender could be “unlearnt” during a short nap. The findings appear to confirm the idea that sleeping provides a unique window for accessing and altering fundamental beliefs – even prejudices that we don’t know we have.

Simply playing auditory cues while people slept partially undid racial and gender bias, the study found, and the effects were still evident at least a week later.

“These biases are well-learned,” said Hu. “They can operate efficiently even when we have the good intention to avoid such biases. Moreover, we are often not aware of their influences on our behaviour.”

The College Board, a nonprofit corporation founded in 1926 to make higher education accessible to more Americans, introduced the SAT (Scholastic Aptitude Test) and, after World War II, the advanced placement (AP) test.

Students who score three of five points on the AP test are credited with completing a two-semester introductory college course in subjects like English, math and history. But revisions are coming, and they’re not going to result in better education.

Periodically, the College Board publishes new frameworks to alert schools to changes in AP tests. The latest American history framework has raised a raging controversy over what should be taught in AP U.S. history classes.

The best way to eliminate grade inflation is to take professors out of the grading process: Replace them with professional evaluators who never meet the students, and who don't worry that students will punish harsh grades with poor reviews. That's the argument made by leaders of Western Governors University, which has hired 300 adjunct professors who do nothing but grade student work.

These efforts raise the question: What if professors aren't that good at grading? What if the model of giving instructors full control over grades is fundamentally flawed? As more observers call for evidence of college value in an era of ever-rising tuition costs, game-changing models like these are getting serious consideration.

Professors do score poorly when it comes to fair grading, according to a study published in July in the journal Teachers College Record. After crunching the numbers on decades' worth of grade reports from about 135 colleges, the researchers found that average grades have risen for 30 years, and that A is now the most common grade given at most colleges. The authors, Stuart Rojstaczer and Christopher Healy, argue that a "consumer-based approach" to higher education has created subtle incentives for professors to give higher marks than deserved. "The standard practice of allowing professors free rein in grading has resulted in grades that bear little relation to actual performance," the two professors concluded.

As a historian, I was influenced by E. H. Carr’s thinking about the past and present as part of a continuum that stretches into the future. In What is History? (1961), Carr argued that concern with the future is what really motivates the study of the past. As a teacher and political activist, I also strongly believe that schools should promote active citizenship as essential for maintaining a democratic society.

in an effort to survive, the NCSS has largely abandoned its commitment to these ideas, twisting itself into a pretzel to adapt to national Common Core standards and to satisfy influential conservative organizations that they are not radical, or even liberal. I suspect, but cannot document, that the organization’s membership has precipitously declined during the past two decades and it has increasingly depended financial support for its conferences and publications from deep-pocketed traditional and rightwing groups who advertise and have display booths.

No Child Left Behind (NCLB). Since the introduction of NCLB, there has been a steady reduction in the amount of time spent in the teaching of social studies, with the most profound decline noticed in the elementary grades.”
