PhD Math & Physics Specialist|Clear explanations, Strong foundations

Penny Z.

I earned my Ph.D. in Physics and have over nine years of teaching experience across university, high school, and middle school settings. Before moving to the United States, I spent seven years teaching mathematics and physics at the university level in China, where I helped students master challenging topics such as calculus-based physics, linear algebra, and advanced mathematics. During that time, I also obtained my university teaching qualification. Since relocating to the U.S., I have taught 8th-grade mathematics for two years and physics for one year, in addition to consistently tutoring students from 5th through 12th grade in mathematics across various levels and curricula.

My teaching approach focuses on building strong foundations and developing true problem-solving skills. I believe students succeed when they understand the “why” behind formulas, not just the steps to get an answer. In my lessons, I break complex problems into clear, logical steps, identify common misconceptions, and teach students how to approach new problems with confidence. I adapt my instruction to each student’s goals—whether that means strengthening core skills, preparing for AP or honors courses, improving test performance, or getting ahead academically.

As a bilingual educator fluent in both English and Chinese, I can support students comfortably in either language, which is especially helpful when explaining abstract or technical concepts. My goal is not only to improve grades and test results, but also to help students think independently and gain long-term confidence in math and physics.
