Dr. De-Yin Jeng

     Dr. De-Yin Jeng is the founder of Jeng Academic Center, Inc. He graduated from National Cheng-Kung University in Taiwan with a bachelor’s and master’s degree in material science and metallurgical engineering, came to the US in 1986 as a student, and received his Ph.D. in ceramic engineering from the University of Missouri-Rolla ( now Missouri University of Science and Technology) in 1991. From 1991 to 1993 he taught in the Material Science Department at UCLA as a visiting assistant professor, and later spent eleven years in industry ( YTC America, Inc.) as a research scientist developing various ceramic CO2, O2, CO gas sensors. In 2004 he began his life-long dream of learning and teaching English at Jeng Academic Center, where he has been teaching all math subjects for primary and secondary schools, AP Chemistry, AP Calculus, various English reading and writing classes, and particularly the highly acclaimed SAT/ACT workshop.

     Dr. Jeng’s teaching philosophy is based on the understanding that intelligence, or academic excellence, alone is not sufficient in satisfying the intellectual, mental, and spiritual needs of young minds. Young students are endowed with latent intellectual and spiritual needs yearning to be guided and helped, usually first through academic achievement, followed by a healthy growth and fostering of their active minds. Young students are naturally thirsty for meaning and value in life, and academic excellence is only the first step in directing their minds. For this reason intelligence is seen as the primary means with which clear, critical thinking skills can be acquired. Armed with high intelligence, young students will be better able to make the best judgment for their lives. The three teaching goals highlighted by Dr. Jeng are a habit of “clear thinking, orderly mind, and deep understanding” of all subjects studied. These three traits pave the way to further development of intelligence, cultivation of virtues, and attainment of wisdom, which is considered as the source of happiness and meaning in life. When all teaching and learning is properly done and achieved between a student and a teacher, both the student and the teacher feel a profound sense of joy, pleasure, and fulfillment.

Candace Newton

Candace Rothstein has been a teacher at Jeng Academic Center, Inc. for six years. After growing up in Southern California with a love for English and Literature, she graduated from Bob Jones University in Greenville, South Carolina with her bachelor’s degree in English with a special focus on Linguistics. She recently graduated with her Masters of Arts in Teaching from George Fox University in Portland, Oregon. She has been an educator for the past eight years, and is currently teaching at Jeng Academic Center in Thousand Oaks, California. Ms. Rothstein also has a passion for writing and is a freelance writer in her spare time.

Ms. Rothstein's philosophy of education is simple, yet effective, and aligns with that of Dr. De Yin Jeng. She believes that students need first to learn how to think before they can learn what to think. Because of this, Ms. Rothstein has spent the last several years focusing her teaching on the art of Critical Thinking and Philosophy. She believes that learning these critical skills helps students to become not only better students but also better human beings.
