    Lincoln High Calculus (微积分) teacher Anthony Yom has given his students the desire to learn and the will to succeed. While his classes are challenging, the educator does all he can to keep his students invested, combining real-life situations and his lessons to show them the value of their work. He challenges us to the maximum, so we do better on tests, sophomore student Alexis Pong told the Los Angeles Times. One of Yom’s other students, 17-year-old Cedrick Argueta, completed a perfect test paper on the Advanced Placement Calculus exam. Only 12 students in the world accomplished this. As for, all of Yom’s other AP Calculus students, each of them passed the challenging exam.

Yom said most of the praise should go to the kids, though he does go above and beyond his students. However, when he first started teaching at Lincoln High, it wasn’t always smooth sailing. Yom felt nervous about the number of students who were unmotivated and unprepared. Some even attempted to physically threaten the teacher. But he didn’t give in. And he gave up his free time to tutor on weekends and during vacations.

At Lincoln High, 80% of the students are Latino (拉丁裔) and Yom hopes to encourage more of them to take his college prep classes, which are currently dominated (支配) by Asians. “I don’t think the Asian students are any smarter than the Latino students,” the teacher states, mentioning that low Latino participation can be connected to cultural differences and expectations. Fortunately, Cedrick Argueta’s AP Calculus success story serves as the perfect example. “My mother cleans houses,” Argueta reveals. “My father is a factory worker.” But the student would be likely to work for NASA or become a teacher.

What is the key to Yom’s success as a teacher? “This may sound dull, but you really have to love them.” the devoted instructor concludes.
