Upper School advisor and science teacher Jennifer Mosher will be departing MFS after 10 years of teaching at MFS.

Mosher teaches Physics First, AP Physics 2, and AP Physics C at MFS, while simultaneously supporting various STEM-related clubs, advising the Muslim Student Union, and guiding her eleventh and twelfth-grade advisees. 

According to Mosher, one of the most rewarding parts of teaching is watching students overcome their struggles in her classes.

“I’ve taught kids [for whom] physics totally wasn’t their thing, but kids who persevered, who struggled through hard classes, who were really proud when they learned something, came back and said ‘what you taught really made a difference,’” said Mosher.

After completing her Ph.D. in physics at the University of Pennsylvania, Mosher was drawn to MFS because of the relationships formed between students and teachers.

“I remember when I first started working here, something I really appreciated was the way

that faculty and students respected each other as people,” said Mosher.

Students have enjoyed the way Mosher encourages them to find answers for themselves instead of simply telling them the answer.

“When she stands up and tells us to whiteboard, I feel like she doesn’t want to fully teach us; she wants us to learn on our own,” said Physics First student Brianna Aguilar ’29.

Other students like her ways of encouraging group collaboration in class.

“I feel like that’s how I learn best if I’m collaborating with other people, and Dr. Mosher provides a space for that, which I really like,” said Frank Pina ’29, who also takes Mosher’s Physics First class.

Over her time at MFS, Mosher has helped several STEM-focused clubs progress at the school, including Aerospace Club, Astronomy Club, Engineering Club, Women in STEM Club, and, most notably, Science Olympiad.

Mosher helped grow MFS’s small Science Olympiad team to a much larger operation, and even supported the introduction of the inaugural mock scrimmage at MFS.

Lucia Rossitto ’29 is a member of MFS’s Science Olympiad team and said she appreciates how Dr. Mosher always listened to the team and supported them with whatever they needed.

“Whenever we need help, she always figures out a way to get to us, [she often] helps us with our binders and notebooks, and she listens to what we think would be best for the team,” said Rossitto.

Olivia Martin ’27, who will be Science Olympiad Co-Captain, Women in STEM Club President, and Astronomy Club President in the upcoming school year, has had many opportunities to work with Mosher.

“[Mosher] is a very dynamic person, and she has so much passion for what she does. I really appreciate the energy that she brings to everything that we do,” said Martin.

“I hope that these clubs have convinced kids that there’s a place for them in science, and that if they want to do science, they can,” said Mosher.

Sam Karatas ’29 is both a student in Mosher’s Physics First class and a member of the Muslim Student Union (MSU). He remembers Mosher’s helpfulness when MSU hosted the Iftar in March.

“[Mosher] was one of the first [people] who wanted to help. She was setting tables and decorations. She didn’t have to be there, but it was just out of the kindness of her heart that she wanted to volunteer,” said Karatas.

Next year, Mosher plans on taking time off from teaching to travel more. Mosher specifically enjoys trips to Morocco.

Mosher has visited Morocco numerous times, including leading an Intensive Learning trip there earlier this year. Mosher intends to continue to learn Arabic while she is there. She has developed an appreciation for their way of life and enjoys Moroccan culture, particularly their community-focused mindset.

“Moroccans really prioritize family ties and helping each other and being hospitable,” she said.

These values also influence her plans for the coming years.

“I would love to do some tutoring or substitute teaching or somehow work with kids on science in some less formal capacity next year,” she said.

Students will miss having a community member who was approachable and always happy to listen and give advice to them.

“I’m really going to miss knowing that Dr. Mosher is always there to talk,” said Emmie Huynh ’27.

As she looks ahead to next year, Mosher shared a final message to the MFS community: “Good luck to everyone. I’m going to miss you, and I’m sad not to be here.”
