The publisher McGraw-Hill has an Online Learning Center, which offers a glossary of poetic terms that you might find useful.

eNotes, an online educational resource, has a study guide to “Wild Geese.” The site also has biographical information on both Mary Oliver and Billy Collins.

Here are two books that might be useful if you wish to explore additional methods of working with youth and poetry:

Lies, Betty Bonham. The Poet’s Pen: Writing Poetry with Middle and High School Students. (Portsmouth, NH: Teacher Ideas Press, 1993).

Somers, Albert B. Teaching Poetry in High School. (Urbana, IL: National Council of Teachers of English, 1999).
