Teaching Philosophy:

"I would typically use real world analogies to explain difficult concepts. For example, if a student said they liked basketball and was learning math, I would frame mathematical concepts in terms of NBA statistics. This makes it much easier for students to comprehend and recall complicated subjects, while also giving them a firmer grasp on intangible concepts. Other than that, I would simplify concepts to examples. Starting broad often confuses students, so I would prefer to introduces concept, and then guide the student through step by step examples."
