Why YouTube Videos Will Never Replace Teachers

Teachers are often thought of as the problem with schools, so replacing them with videos can seem like an easy solution.

The "flipped classroom"—which switches the order of classroom instruction and homework—is the latest education craze. Instead of receiving in-class lectures from a teacher, students watch a video lesson on YouTube. The next day, they head to school and do homework under the teacher's supervision. Flipped classroom advocates say the model is more effective because students have their teachers and peers with them to give them feedback when they encounter problems with homework.

But there's a major flaw in this innovative model: the nation still has a tremendous digital divide. Uruguay ranks ahead of the United States in laptop distribution. Maine is the only state to make a significant investment toward ensuring all students even have the computer technology they'd need to watch videos at home. And even giving students laptops doesn't mean they can access the internet at home. With poverty skyrocketing, some families simply can't afford it. True, Chicago partnered with Comcast to give give internet access to low-income families this year, but that kind of effort is still the exception.

Good teachers don't spend in-class time giving old-school, boring lectures while students passively sit at their desks, trying to avoid falling asleep. Savvy educators know lectures aren't a recipe for student success, and they mix up their approaches accordingly—sharing a small amount of information in an interactive, engaging manner, while incorporating multimedia and discovery-based approaches.

The other element left out of the flipped classroom discussion is that watching a video is no more active or engaging than reading a textbook. And what happens when a high school student is assigned videos from all six of her classes? Do we really expect students to watch two or three hours of videos at night?

And while the flipped model emphasizes doing homework in an environment where students can seek help, practicing solo is designed to be a skills check, not students' first exposure to the material. If students don't yet understand a concept, they shouldn't have it assigned as homework. Of course, it would be easier for teachers to adjust instruction to meet individual students' needs if budget cuts hadn't created larger class sizes and axed teacher assistant positions from schools.

That's not to say that using videos to supplement teaching is a bad idea. Teachers are already identifying students that need extra help and using videos, podcasts, and other media to meet academic needs. But just as someone can go to a library every day and never learn how to read, students need someone to facilitate their learning: a teacher.

At a time when teachers are often thought of as the problem in schools, replacing them with videos may seem like an easy solution. But if a student has a question about a lesson, a video can't give her an answer. And, as many times as I've watched my own kids practice concepts with videos or other learning tools, I've never heard them say they loved them. The teachers who've made a difference in their lives are beloved. And that's enough to convince me they'll never be replaced by YouTube.

Christopher Columbus, Alexander Hamilton, William Shakespeare, and Sir Walter Scott are getting company. Statues of the famous men are scattered across Central Park in New York City, along with 19 others. But they'll finally be joined by a few women.

Susan B. Anthony, Elizabeth Cady Stanton, and Sojourner Truth are the subjects of a new statue that will be on display along The Mall, a walkway that runs through the park from 66th to 72nd street. It will be dedicated in August of next year, which is fittingly the 100-year anniversary of the 19th Amendment that granted women the right to vote.

Currently, just 3% of statues in New York City are dedicated to women. Out of 150 statues of historical figures across the city, only five statues are of historical women, including Joan of Arc, Golda Meir, Gertrude Stein, Eleanor Roosevelt, and Harriet Tubman.

It's easy to become calloused to everyday headlines with messages like, "the world is ending" and "everything is going extinct." They're so prevalent, in fact, that the severity of these statements has completely diminished to the point that no one pays them any attention. This environmental negativity (coined "eco-phobia") has led us to believe that all hope is lost for wildlife. But luckily, that isn't the case.

Historically, we have waited until something is near the complete point of collapse, then fought and clawed to bring the species numbers back up. But oftentimes we wait so long that it's too late. Creatures vanish from the Earth altogether. They go extinct. And even though I don't think for a single second that we should downplay the severity of extinction, if we can flip this on its head and show that every once in a while a species we have given up on is actually still out there, hanging on by a thread against all odds, that is a story that deserves to be told. A tragic story of loss becomes one about an animal that deserves a shot at preservation and a message of hope the world deserves to hear.

As a wildlife biologist and tracker who has dedicated his life to the pursuit of animals I believe have been wrongfully deemed extinct, I spend most of my time in super remote corners of the Earth, hoping to find some shred of evidence that these incredible creatures are still out there. And to be frank, I'm pretty damn good at it!

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

Wealth inequality has been a hot topic of discussion as of late, but it's something that's occurred all throughout history. Class structure is a complicated issue, especially when you consider that haves and have nots have been in existence for over 4,000 years.

A study published in Science took a look at over 100 late Neolithic and early Bronze Age skeletons found in a burial site in southern Germany. The study "shed light on the complexity of social status, inheritance rules, and mobility during the Bronze Age." Partly by looking at their teeth and the artifacts they were buried with, researchers were able to discover that wealth inequality existed almost 4,000 years ago. "Our results reveal that individual households lasting several generations consisted of a high-status core family and unrelated low-status individuals, a social organization accompanied by patrilocality and female exogamy, and the stability of this system over 700 years," the study said.
