Teachers across the country are finding their classrooms increasingly diverse, and this booklet is designed to help teachers cater to the needs of English language learners, both in ESL and non-ESL classrooms. By examining the background of English language learners, this booklet helps teachers to create a framework for organizing the classroom environment. Practical classroom strategies for literacy and content education are also emphasized. As a part of the What Every Teacher Should Know About Series, this guide can be packaged for free with a core Education text (with each additional WETSKA guide added at a cost of $2 net to the bookstore) and can also be purchased individually.
