While it is commonly assumed that teaching children is unrelated to teaching at the advanced level, the two kinds of teaching are closely related and mutually effective. The experience of teaching young learners can benefit the instruction of college students of English as a second language. In both cases, providing motivation is a challenge. Materials should be appealing, varied, authentic, challenging, and topic-oriented. Teaching children requires consistency and clarity of goals and requirements, and diversified tasks for a sense of achievement, as do adults. The games and role-playing activities involved in teaching children should also be used to teach adults. While children have a love of sound, older students need to be encouraged to enjoy it. Children's need to relax occasionally into their native language suggests that the same practice would be useful for adults. The teacher who has learned an essential element of teaching children, being available to them, has learned to be more relaxed with students. The needs for timing, recognition of individual developmental differences, and awareness of the learner's responses are similar for both age groups. (MSE)
