Education innovation: Our window of opportunity is here

Technology is an important tool, but it will take an ecosystem of educators, students, and caregivers to make the most of it.

  • The old adage that it "takes a village" has proven true for education in the time of coronavirus. What constitutes a "school" and who is considered an "educator" has changed out of necessity, but important opportunities for the future have come from these unexpected circumstances as communities have and continue to adapt.
  • "The greatest human superpower is empathy," says Kaya Henderson, "the ability to deeply connect with other people and to see yourself in them and to see them in you." She argues that "a part of the reason why we are so divided in this world today is because we see people as 'other' and we don't see them as extensions of ourselves."
  • While technology has become a big part of the education landscape, community is still the keystone. "I want technology to amplify and to scale excellence," Henderson says. "To amplify knowledge and to scale excellence all at the same time while paying deep attention to the human connections that are integral to education."

The ​'Motte & Bailey' meme reveals what's wrong with political arguments in 2020

This medieval-themed meme highlights a shady yet all too common rhetorical move people make in arguments.

  • The "Motte and Bailey Doctrine" was developed by philosopher Nicholas Shackel.
  • It describes a rhetorical move in which an arguer advances an indefensible opinion, but when challenged falls back upon a similar yet easier-to-defend opinion.
  • Motte-and-baileys have become a weapon of choice in political and culture-war arguments.

How can we design schools to be anti-racist?

From reassessing the way schools are funded to changing the curriculum, there are ways to fix the inequities in education.

  • Recognizing when something is overtly racist is easy, but when it comes to education in America there is often subtle and systemic racism at play that can put children at an early disadvantage. Chris Lehman of the Science Leadership Academy says that now is the time to have these important conversations and to design schools to be anti-racist.
  • Lehman says that in Philadelphia, the amount of money spent on one child's K-12 education can be $170,000 less than that of another child who lives in the suburb just a block away. These racist systems and structures are in place in cities across the country but are often not addressed.
  • Family income directly translates to the amount spent by the public to educate children. "That's one of the most anti-American things I can imagine," Lehman says about the racial and socioeconomic inequity. While funding is a major component, changes must also be made at the curriculum level.

Why school leadership and student critical thinking need a desperate do-over

Educators have proven that they can "turn the aircraft carrier" when they need to, but the system needs to match their efforts.

  • For many people in the world, the idea that education is not changing at the same rate as the rest of the world became more apparent at the start of the coronavirus pandemic. Grant Lichtman argues that the hierarchical systems that govern education and other organizations (military, political, business, etc.) don't work in times of rapid change, and thus need to be overhauled.
  • "What has started to replace that are vastly more distributed systems of leadership," Lichtman says. This results in more timely decision making and a more collaborative environment with more room to try new things, more freedom to fail, and the opportunity to take ownership of and learn from those failures.
  • Lichtman stresses that things like civil discourse and empathy should be made a priority in the curriculum. "We as educators and we as parents should be focusing enormous amounts of effort on helping our students to understand things like the nature of truth, objective reality, who to listen to, what is the difference between an expert and a person who just has a large social media feed?"
