Meet Faculty and Students

Commonwealth teachers will never put you in a box. They’re always very much trying to connect the ideas we learn in the classroom to what’s outside it. Like, in history class, if you're learning about politics in ancient China, you’ll also think and talk about politics right now. Commonwealth never keeps the learning inside the classroom...which is something I hope I keep with me for the rest of my life: that love of learning and knowing that it doesn't only have to happen when there's a teacher and a whiteboard.

I feel so lucky to get to go to Commonwealth, and I am amazed at the quality of what happens here.... I never want to forget that this is not the normal experience for most people. One example is generative AI: I will meet other high schoolers, and I'm shocked at how much AI they use or they're encouraged to use, and I'm grateful that doesn't happen here, because I want to learn how to critically think.

Caro ’27

Commonwealth has opened up a path to relationships with both students and teachers that I hadn't really seen before. I have teachers that I can rely on, that I can ask questions of and meet with, and I want to continue having those relationships in the future with my professors in college and bosses at jobs. Commonwealth really built a strong foundation for that.

Tomi ’27

There are so many different kinds of people at this school with so many different outlooks in life. Even if you disagree with someone's views, I feel like here you can still have a respectful conversation. And I think that's a really important life skill: to be able to talk to people you don't necessarily see eye-to-eye with.

Really exciting classrooms are where the student is part of the circuit and the electricity is jumping between them and the sources and the teacher. At the beginning of the Enlightenment unit, instead of saying, 'This is what the Enlightenment is.' We say, 'Here's Newton's laws of natural philosophy. Here's a poem about sinful bees. Here’s a little Montesquieu with a little Benjamin Franklin and a little Smith.' And then we try to figure out what they have in common.

Melissa Glenn Haber ’87, History Teacher

I get a real burst of energy when I’m able to help students navigate the complexities of the research process. I feel so lucky to have such an incredible patron base of high-level readers and thinkers in our students. 

Jake MacDonnell, Librarian and Registrar

There are all of these resources around us that we can take advantage of.… I like how part of your daily routine is going out into the city and still being with your classmates but in a completely different setting.

grace-hopper-research-paper

Through our history curriculum, Commonwealth students learn how to be historians rather than passive absorbers of facts. They read and analyze primary sources from a variety of voices in their historical contexts. And they graduate knowing that a single textbook could never tell the whole story. Core to this discovery process is an annual research paper that hones students’ analytical and writing skills and challenges them to dig deep into a variety of sources on any topic of interest, whether it be debunking the “primitivist” myth around jazz, the impact of the breakup of the AT&T monopoly, or, as you will see in this recent example, where Siri '27 finds parallel fears over artificial intelligence in computer science today and the "automatic programming" introduced by Grace Hopper in the 1950s. In both eras, women programmers were—and are—the most vulnerable to extinction.

Toko ’28 looks for the bigger picture. Studying for a test? She zooms out to examine the trajectory of her learning throughout the course. Her favorite classes? Those that deepen her understanding of how they connect to others. And her take on Commonwealth students? They’re talented academics…but they’re a lot more than that, too. Read on to learn more about this rising junior and the wide-angle view she brings to everything from English class to lunch clean.

How to  Predict the  Unpredictable: Alumni/ae in Economics and Finance Field Questions from 151 Comm. Ave.

For those who aren’t seasoned in economics—and even for many who are—trying to predict financial news or policy moves can feel like starting a seven-season prestige drama at its midpoint and trying to guess the end. Who will react to a new tariff measure and how? Will that much-hyped startup keep rocketing upward or crash and burn? What role will artificial intelligence play: savior or villain?

As you might expect, the Commonwealth community has met the moment with a drive to learn more, leading to student groups like the Investment Club and Project Weeks spent at organizations like Fidelity Investments and government finance departments in Greater Boston. So when we invited students and faculty to share their questions for alumni/ae experts who work, broadly, in economics, finance, and investing, they leapt at the chance. Below you’ll find that Q&A, and—spoiler alert—the insights alumni/ae had to share, about career-building, risk, and human behavior, applied beyond the market. 

Teaching the News

It’s a Monday afternoon in early March. The winter play is days away, French and Spanish students are preparing to jet off to their studies abroad, seniors will embark on their projects soon, and the third quarter of the school year is about to end. Despite their novella-length to-do lists, about twenty students are seated in 2C, listening intently while quietly eating their lunches. 

For these students, lunchtime has turned into “an emergency meeting of Current Events Club,” as announced as recess that morning, given the war with Iran, now on day three. Some students offer thoughts on the motivations for war or pose questions about what they’ve heard online or at home; others provide live updates as they receive news alerts from an ongoing press briefing. The rest simply take in the discussion, digesting their food and the specter of war before resetting for sixth period.

Whether frequenters of Current Events Club or not, Commonwealth students are grappling with the national and world events that will define, at the very least, their high-school years. How do we, as teachers, mentors, and an educational institution, guide them through the realities of our times? It’s a responsibility that stretches across academic disciplines and areas of school life, and one that our faculty and staff approach with varying perspectives but shared intentionality.

Any parent of school-aged children will tell you: filling kids’ summers is hard. But Rod Hsiao ’82 knows the problem goes deeper than the scramble to find summer camps. Those months away from school can torpedo students’ momentum in the classroom and deepen achievement gaps along socioeconomic lines. He’s spent his career trying to close that divide by improving access and outcomes for students, eventually co-founding InPlay, a nonprofit that helps under-resourced families find the summer and after-school programs that can change the trajectory of students’ lives. 

At Commonwealth, we’re looking for inquisitive, driven, and creative students from a wide range of backgrounds. We encourage you to visit us, talk with teachers and students, and see if Commonwealth is right for you.
