We are so excited to have the WISIT Summer Institute (WISIT) back on the Tregaron Campus!

began this morning with a welcome from Director Elise Stephenson and then a plenary from Project Zero researcher Ron Ritchhart focused on “Who are our students becoming as thinkers and learners as a result of their time with us?”

We’re thrilled to welcome educators from all over the country, and even Germany and China this year! This intense and fun professional development will continue all week with learning groups, interactive courses, art happenings, and a day at the museums of Washington, DC.

We’re looking forward to an incredible week of learning and collaborating!

What a weekend!

It was such a joy to welcome alumni, former faculty, families, and friends back to WIS for Alumni Reunion Weekend. From celebrating our retiring faculty, BĂŠatrice Ferrant and Gema Leon, to catching up in the Mansion, touring campus, and enjoying a beautiful Saturday Lawn Party, the weekend was filled with great conversations, laughter, and plenty of WIS memories.

Thank you to everyone who joined us, traveled from near and far, and helped make the weekend so special! We loved having you back on campus and can’t wait to see you again soon.

Yesterday, two more Grade 5 students were whisked away from the Primary School by Head of School Suzanna Jemsby and their English teacher Paul Skipper for another day of Hooky with the Head!

Frida and Junia started their special day at Starbucks before heading to a hip hop dance class, where Suzanna said “Paul and I were most definitely not the experts.” Frida and Junia picked up the dance right away!

Next up was lunch at Chipotle followed by a trip to the Spy Museum. The day ended with “outrageously large ice creams” and a download of all the Grade 5 gossip before returning to the Primary School.

Thanks to Frida’s parents for bidding on this great item at the WIS Auction, and thanks to Ms. Jemsby and Mr. Skipper for being such good sports and giving the girls a day they will never forget!

On Tuesday, Grade 5 students Lyla and Lena were surprised to learn they would not be attending their classes. Instead, they would be playing hooky with Head of School Suzanna Jemsby and their English teacher Gauri Dave!

The day started at Starbucks with some refreshments before the group moved onto an art studio for some leaf printmaking. While their artwork dried, they moved onto an escape room, where they were able to beat the clock by seven seconds, and only needed 10 clues! (For comparison, a group of eight last week needed 38 clues, and were unsuccessful in escaping).

Lunch was at Osteria Mozza, where Lyla declared "this is the best pasta I've ever had!" Afterwards, they did some window shopping on M Street, including a stop at Barnes & Noble, where Lena found a book that her father wrote.

They day ended with ice cream at Häagen-Dazs before picking up their artwork and heading back to school, where they got a sneak peek of this year's yearbook.

Thanks to Lyla's parents for bidding on this great item at the WIS auction, and thanks to Ms. Jemsby and Ms. Dave for giving the girls a day they will never forget!

Yesterday, Grade 8 students presented their Keystone Projects to friends, family, and faculty. Now in its fourth year, the Keystone Project is a bridge between the Grade 5 PYP Exhibition and the Grade 10 Passion Project, and is the culminating activity for Middle School students.

This project required the students to reflect on and then take action on the idea of global thinking and action, relating to the last part of the WIS Mission: “global in reach.” They started with a research question and conducted field studies during their grade-level trips to Paris or Madrid. A bilingual presentation and product were shared with attendees at the Keystone event; this year’s topics covered an array of subjects, such as:

-the effects of social media use on teens
-organization of green spaces
-food insecurity
-urban planning
-public transportation
-mental health
-health effects of smoking

Congratulations to the students for their engaging and thoughtful presentations — and on being so close to completing !

On Friday, May 29, Preschool and Pre-K students held their final Celebration of Learning forcused on the Five Senses, with the central idea: “Our senses guide us in our observations, investigations, and decision-making.”

After some group performances by our youngest learners, parents and students were invited to explore each sense at different stations, including blind taste-testing for the very brave!

Congratulations to these young learners and their teachers on a wonderful year of language immersion learning!
