Today, in many high schools, teaching is now a technical miracle of computer labs, digital cameras, DVD players and laptops. Teachers e-mail parents, post messages for students on online bulletin boards, and take attendance with a quick movement of a mouse.
Even though we are now living in the digital age, the basic and most important element of education-the human connection—has not changed. Most students still need that one-on-one, teacher-student relationship to learn and to succeed. Teenagers need instruction in English, math or history, but they also want personal advice and encouragement. Kids talk with me about their families, their weekend plans, their favorite TV shows and their relationship problems. In my English and journalism classes, we tall about Shakespeare and persuasive essays, but we also discuss college basketball and career choices. Students show me pictures of their rebuilt cars, their family vacations, and their newborn baby brothers. This personal connection is the vital link between teacher and student that no amount of technology can improve upon or replace.
A few years ago I had a student in sophomore English who was struggling with my class and with school in general. Although he was a humorous young man who liked to joke around, I knew his family life was far from ideal. Whenever I approached him about missing homework or low test grades, he always had the same reply : "doesn't matter because I'm quitting school anyway." Even though he always said this in a half-teasing way, I knew he needed to hear my protests and my "value of a high school education" lecture. He needed to hear this speech from me because I understood his family problems and he knew that I believed in him. After he left my class, he struggled through the next two years of school. But, he did finally graduate because we kept telling him to hang in there. We'd cared about him finishing school.
Students rely on compassionate teachers to guide, to tutor, to listen, to laugh and to cry with them. Teachers provide the most important link in the educational process—the human one.

A. the variety of modern teaching methods
