Math Professor, Geo, SAT, Calculus, Precalculus, Algebra 1&2

Lei W.

I hold a Master of Arts in Teaching Mathematics from SUNY Stony Brook University with comprehensive training in mathematics pedagogy and evidence-based instructional strategies. I currently teach as an Adjunct Professor at Farmingdale State College (Calculus with Applications and Pre-Calculus) and have extensive experience teaching Algebra 1 and 2, Geometry, College Algebra, and all levels of Calculus. Previously, I worked as a math instructor at Stony Brook University, facilitating discussion sections and providing one-on-one tutoring. My dedication to student success earned me the Joseph and Virginia Roller Award for Excellence in Teaching. I have consistently helped students raise grades from failing to passing, improve letter grades by one to two levels per semester, and achieve 100+ point improvements on SAT Math through targeted preparation.

Over several years, I have worked with students from middle school through college level (ages 12-18+) across traditional classrooms, one-on-one tutoring, small groups, and remote environments. I specialize in high-stakes assessment preparation including SAT Math, AP Calculus exams, and state standardized tests. My students consistently achieve and exceed target scores, with several earning 4s and 5s on AP Calculus exams after struggling with foundational concepts.

My approach emphasizes conceptual understanding through discovery-based learning and diagnostic assessment. I identify specific difficulties, then create customized learning plans that systematically address gaps while building toward goals. I integrate interactive activities, visual technology (Desmos, GeoGebra), and real-world applications. For test prep, I employ strategic problem-solving techniques, time management strategies, and focused practice on high-yield topics. I provide structured guidance while fostering independence and growth mindset—helping students improve grades and test scores while developing lasting confidence and problem-solving abilities.
