Cheryl Childers, Teacher, Consultant on Educational Guide

Cheryl grew up in Saugerties, NY - in the heart of the Catskill Mountains. She moved to Alaska in 1980 and by 1988 was teaching school in Unalaska, Alaska and is now in her 25th year of teaching in Alaska. As a teacher, she has been inspired by those who believe the purpose of education is to inspire a life-long love of learning. Educators like Alexander Sutherland Neill, founder of the Summerhill School in England and Alfie Kohn, author of books The Schools Our Children Deserve, and Rachel Carson, naturalist and author of The Sense of Wonder have had an influence on her personal philosophy of education. Cheryl believes that most of the relevant education in a child’s life takes place outside of the four walls where they spend most of their learning lives. For this reason, it is imperative we make learning mirror what’s happening ‘outside’ as much as we can.
