I have always loved math. It has a rhythm and logic that makes sense to me in a way few other things do. But even with that love, I did not always have confidence in myself. When I was in middle school, I was placed in honors math, but when it came time to move a year ahead in high school, I hesitated. I took Algebra I again in my freshman year because I was not sure I could keep up. While my friends continued down the accelerated path, my final high school math class ended up being Algebra II, while theirs was Calculus.
Looking back, I wish I had believed in myself sooner. My first experience with calculus did not come until community college, and the environment there was very different. The learning experience was not as personal as what I might have had in high school. Calculus can be challenging even under the best conditions, but in large college classes where you are mostly on your own, it can feel intimidating. I struggled to connect with it the way I wanted to, and I realize now how much that early lack of confidence limited my opportunities.
At one point, I briefly considered studying chemical engineering. I loved math and chemistry, and I wanted a career where I could use them together. But the first physics class I took scared me away. Physics is basically applied calculus and I did not feel strong enough in calculus to understand it fully. I remember feeling frustrated that something I loved so much felt just out of reach. Engineering is, in many ways, a degree built on physics and calculus, and had I been more confident and better prepared, I might have continued down that path.
Even though I did not pursue engineering, my love for math never faded. It continued to show up in my life in small ways, helping friends and family with homework, tutoring, or explaining concepts to classmates. Over time, I realized that what I truly enjoyed was not just solving problems but helping others understand them. That realization changed everything. I decided to major in mathematics and eventually became a high school math teacher.
Now, as a teacher, I see calculus from a completely different perspective. It is not just another class; it is a gateway. Calculus opens doors to careers in science, technology, engineering, and so many other fields. I tell my students that understanding calculus means understanding how the world changes, how things grow, move, and interact. It is the foundation for innovation. Whether they dream of becoming doctors, architects, or software engineers, calculus gives them the tools to think critically and apply what they learn to real life.
When I think back to my own journey, I want my students to have more confidence than I did. I want them to see calculus not as something intimidating but as something within their reach. I remind them that the effort they put in now could open doors later that they might not even know exist yet. Every time I see a student challenge themselves or begin to see the beauty in math, I feel like I am helping them build the confidence I once lacked.
Calculus is important in the STEM field because it represents possibility. It connects curiosity to understanding and gives students the power to imagine, design, and create. For me, it has come full circle, from the class I was once too afraid to take to the subject that now helps me inspire others to believe in their own potential.
