I have taught many subjects in biology, to adults and teenagers, to single mothers and Ivy League first- year students, in small seminars and large classrooms. Still, my approach to teaching is grounded in the perspective I gained during my first year as a teacher in El Salvador and the lessons I learned there: Make the subject fun. Show your students you care about their learning and academic achievement . Be creative and try different techniques until you reach the students who don't engage in advisory services. Understand that your experience is different from that of your advisory students. Be explicit about the criteria for success. Show respect and work hard and expect respect and hard work in return.
