Christian Zamora - Country Day School

Mathematics Teacher

After completing my degree in Mathematics in Boston, I returned to Costa Rica and worked for four years at the University of Costa Rica, mainly teaching linear algebra, but also calculus and number theory. I coordinated the Linear Algebra for Computer Science course and had various teachers under my supervision while taking care of logistics and also designing the evaluations. I also worked for ExMa, which is a program for helping students who have fallen behind in their math courses.

At the same time, and as an unpaid project, I created and took care of AAL, a website that allowed students from all over the country to get help for linear algebra online. At its peak, it had close to 300 users. Finally, during my final year, I was a member of the National Committee for Math Olympiads and was also part of the National Jury, an honor that I have had 4 times at this point.

In 2016, I began working at CDS, where I have had the privilege of teaching college-level classes like AP Calculus AB, AP Calculus BC, and Honors Linear Algebra, while also coordinating the Math and Science Competitions Club where the students have achieved great success at both national and international level.

I love learning and growing as a person, so being part of such a diverse and rich community like CDS has made me become a better professional and, more important, a better human being. Besides learning through meeting people, and also through my love of reading, I also enjoy other hobbies like playing video games and basketball and watching soccer.
