The 54th AAIE-New York City-CONVERSATION: February 1-5, 2020

"Diverse on Purpose, Different By Design"


 

We Learn Through Conversations...

If you're going to travel to New York in February 2020, with many of you from the other side of the planet, then it's the job of AAIE to make sure we hold important CONVERSATIONS.

We can see nothing more important than our theme for 2020: Diverse on Purpose: Different by Design. And to explore the questions that matter. Our theme calls for us to be more than 'diverse by accident' simply by virtue of our student populations. In troubling times, with the politics of polarity gaining ground, international education is uniquely placed to embrace the power of diversity with a renewed sense of common purpose, or to 'make a difference on difference.'

This year's conversation will pull together multiple threads of diversity: from those who learn differently, supporting linguistic equity, building success on our different strengths, addressing key issues such as ethnic diversity in our faculties and women in leadership, socio-economic disparity and access to our schools..the things that many of us care deeply about.

We need your voice in this CONVERSATION. Contribute your voice and expertise at AAIE in New York in 2020. 

Best wishes,

AAIE Trustees

Un-Keynotes

Dacher Keltner

"21st Century Power: Principles, Practices, and Positive Social Change"

2:30-4:00PM Monday, February 3rd

We are in the midst of a power revolution, one moving away from older, Machiavellian approaches to power, which prioritized coercion and might, to more collaborative, compassionate models of power. In this talk, Dacher Keltner will detail a roadmap for 21st century power, one oriented toward social change and embodied in Collaborative Practice. He will speak about the need to think what power is: not money, class, coercion or might but rather our ability to make a difference in the world. Keltner will detail the principles of collaborative power, which include empathy, giving, gratitude and stories that unite, all of which earn the esteem of others and stir social networks to effective action. He will address the abuses of power, from empathy deficits to impulsivity, which can undermine any human at work, in family life, in marriage and offer ideas about what can be done to promote social change in the face of such timeless pitfalls.

"How Never Fitting in Became Fitting in Everywhere"

8:45-9:45AM Wednesday, February 5th

In her hilarious keynote, Firoozeh Dumas will share her improbable journey from Abadan, Iran to the bestseller lists of the NYTimes. Not only does Firoozeh believe that our commonalities far outweigh our differences but she also believes that our stories connect us. Hearing her story will make you want to share yours, and hear everyone else's. 

Her book, Funny in Farsihas developed a cult following among educators, selling almost half a million copies. It is part of the curriculum in many junior highs, high schools and colleges around the country where it is often the only humorous and most popular book on reading lists. Even though students are initially hooked in by the humor, educators have found that Firoozeh’s books are a gateway to many conversations, including shared humanity, immigration, language, family and identity. A free study guide is available on her website.

10:10AM-10:45AM

Location: Broadway Ballroom, 6th Floor

How best to ensure a collaborative relationship between head of school and board trustees, from the viewpoint of a diverse group of trustees from around the world. Essential questions that will guide this panel discussion will include the following:

  • What is a trustee's view on the best ways to contribute toward realizing the school's mission, core values and strategic thinking?
  • What are the best ways to ensure transparent communication that also respects trustees and senior leaders flying at their respective proper altitude?
  • How best to ensure the most productive relationship between the head of school, board chair and across all trustees?

"The Best mistake I ever made"

a community learning session with kevin glass, tim carr and deb welch

10:45AM-11:45AM

Location: Broadway Ballroom, 6th Floor

We say all the time "mistakes are opportunities for learning," but mostly they are not. They are usually just mistakes, and so unfortunately we tend to repeat them. If we want our mistakes to be opportunities for learning then we need to devote the time to reflect and truly problem solve. Even better is for the leader to reflect on mistakes with peers and to be ready and open for feedback. 

This session will engage the entire AAIE community in a CONVERSATION to consider "the best mistake I ever made" and to do this in small groups with global colleagues. The "best" mistake is the one from which we learn the most during our careers. In each small group, each AAIE leader conducts the following "after-action" analysis."

  • What was supposed to happen?
  • What actually happened?
  • What accounts for the difference?
  • What did I learn?
  • Why was it so important?

The goal of this session is for leaders to be vulnerable, open and honest. To recognize that everyone makes mistakes and that by telling their own stories to a focused audience of peers, we genuinely learn from our mistakes and those of others. It really is a CONVERSATION where we practice self-reflection as an essential means of learning.

"I am white, male and privileged. i am also biased, prejudiced, and have many 'ists' and 'isms.' why has it taken me 51 years to see this?" - A Kevin Glass HeadTalk

2:00PM-2:20PM

Location: Broadway Ballroom, 6th Floor

Anyone who has taken the Intercultural Development Inventory or one of Harvard’s Implicit Bias tests was either a) shocked, or b) dismissive of what was uncovered. "Culturalism" (Yuval Noah Harari) appears to be the new “ism” for this part of the 21st Century and, thus far, what a divisive time we are all living in. I believe the very first step for us is that we need to lead with empathy and curiosity and suspend judgment. We need to model this for all those fellow humans, young and old, like us and different, that we are responsible for, have influence over and come into contact with through our incredibly privileged lives.

2:20PM-3:10PM- Wake-Up Call: Child Protection Panel Discussion

Location: Broadway Ballroom, 6th Floor

A child in your school is harmed by someone else.  The impact of this event on that child's life and educational attainment will likely be life-long.  If an adult or child in your community caused the harm the impact on your community, your learning environment, and your staff and student wellbeing can reverberate for years--shattering trust, enabling abuse and silencing victims and bystanders.

Our multi-disciplinary panel will discuss how your institutional response to harm can support healing, prevent further trauma and aim for positive response even when local resources are scarce or unreliable. Team will share examples and cases they addressed in addition to the considerations that apply to every child protection case.

Deb Welch will moderate the panel which seeks to answer:

  • What resources are available to me?
  • What does appropriate response mean in the 'real' international school world?
  • How do you manage expectations and recovery of staff, parents and the Board and share a common understanding about confidentiality and transparency?
  • What does an inquiry encompass, how is it different from an investigation and how do we get the training we need to even accomplish this work?
  • How do we recover when the response goes wrong?

3:10-4:00PM - Diversity Conversations: Addressing the Social and Collateral Implications of Recruiting Diverse Leaders

Location: Broadway Ballroom, 6th Floor

The lack of diversity in leadership within our international schools is not representative of our student populations. According to the U.S. Department of State Assisted Schools, 93.26% of school leaders are white, with 76% of them identifying as male. Our students are watching and it is time for our schools to address the elephant in the room. This session will provide an opportunity for open and honest dialogue between representatives from international recruiting agencies and our school leaders. The definition of diversity in your particular school will vary according to country, population, financial resources, mission and purpose, even governmental restrictions. We understand the unique restrictions many schools face. Together we will work to find solutions within your context.
