Whether it’s encouraging students to do their best or simply offering a smile when it’s needed most, Ms. Sibille leaves a lasting impression on everyone she meets. By following along in this highlight, you’ll discover just how much Ms. Sibille loves her students and why she’s such an important part of the Doherty community.
Ms. Sibille’s Beginning…
Q. Can you share a bit about your background and what inspired you to become a substitute teacher?
“About three years ago, I moved from Louisiana. My son was starting first grade, so it felt like the perfect time to move. I started working here three years ago in culture and climate, which is a team of about five people you often see walking around the school. Last year, I was offered this position and started about a year ago. Eventually, I hope to become a teacher.”
Q. How long have you been substitute teaching, and what first motivated you to take on this role?
“About a year. My motivation is being able to see the kids and be in the classroom every day, just in different classrooms. I still get to see the entire student body instead of being in one room all day. I’m interacting with the same number of students, just different ones, which I enjoy. It also helps me gain more experience for when I become a teacher.”
Q. What subjects or grade levels do you enjoy teaching most, and why?
“I like all grade levels, but I’d probably choose seniors. When I started, they were sophomores, and I’ve enjoyed watching their growth as they’ve become seniors preparing to graduate. Subject-wise, I’d choose science or ETA. I like these subjects because students are always working on projects and staying engaged, which is nice to see. Gym is also a good one. “

Inside the Classroom:
Q. What’s your approach to connecting with students when you walk into a new classroom for the first time?
“I always make sure to say good morning, acknowledge that students are in the classroom, and ask them how their day is going. If I notice a student seems upset, I try to speak with them one-on-one to see what’s wrong and what’s going on. I enjoy engaging with students throughout the day and making them feel seen and supported. At the end of class, I like to tell them to have a good day.”
Q. Can you describe one of your most memorable or meaningful experiences as a substitute teacher?
“At the beginning of the school year, I was in a freshman class for a little over two weeks. During that time, my freshman students realized I would be with them every day, and seeing their reactions when they noticed it was me again felt very meaningful. They were genuinely happy to see me. Now, when I see them in the halls, we have a connection, they recognize me and know who I am, even though they’re new to the school. Building that relationship with freshmen was especially meaningful because you don’t always expect to form strong connections with students who are just starting out, but whenever I sub for them now, they’re excited to see me.”
Q. What’s something students might not realize about what it’s like to be a substitute teacher?
“Sometimes it’s challenging because of the rules and expectations. When students see there’s a substitute, they may think it’s going to be an easy day. However, we still have to follow school rules, such as putting cell phones away and completing assigned work. It’s still a normal school day, not a free period or a time to just chat. Helping students understand that can be difficult, but it’s important.”
Q. How do you keep students engaged and motivated, especially when they’re missing their regular teacher?
“I try to encourage students to work on assignments for another class if they’ve finished their work. If they have their Chromebook and nothing else to do, they can play appropriate games. I also consistently remind them that they’re still in class and need to stay on task, we’re not making TikToks or treating it like free time.”

Beyond the Classroom
Q. Outside of teaching, what are some things you enjoy doing in your free time?
“I go to the gym almost every day and enjoy staying active. As a mom, my routine includes coming to school, picking up my son, helping with homework, going to the gym, cooking dinner, and then getting ready for bed. On the weekends, we spend a lot of time together. My son plays soccer, so during soccer season we’re often at games, and we also enjoy doing outdoor activities.”
Q. Do you have any hidden talents, fun facts, or unique skills that your students might be surprised to learn about you?
“For hobbies, I enjoy hand embroidery and woodworking. I have several tools, including a scroll saw, and I also like to sew from time to time. So like old grandma hobbies. I have two cats named Ella and Willow, one is 9 and the other is 8. “
Q. If you could describe your teaching philosophy or personal motto in one sentence, what would it be?
“Empathy. I care deeply and don’t like seeing kids feeling sad or unsupported.”

School Spirit:
Q. What do you enjoy most about being part of our school community?
“I love the sense of engagement and community at the school. Everyone is so close; teachers, students, and even families. I enjoy seeing that connection and being part of a team that works to engage and motivate students.”
Q. If you could share one piece of advice with students about learning or life, what would it be?
Never give up. Always pursue your goals, keep pushing forward, and stay determined to achieve what you want in life.
Q. As we move through the school year, what’s something that continues to inspire or motivate you in your work?
One of the best things is the support from administration. If there’s ever an issue, we can go to our assistant principals or principal, and they’re always willing to listen and back us up. It’s great to feel heard, whether it’s about something in a classroom or in the hallway, and it’s reassuring to see that they take action when concerns are raised.
