The Purdue Online Writing Lab (or OWL, as it is affectionately known) is one of the world's most popular online writing resources. So it is no surprise that this list of ESL Teacher Resources is as inviting as it is comprehensive. As the site notes, the list contains resources both theoretical and practical; it links to organizations and journals as well as to online teaching and reference materials. Educators working with English language learners may like to begin at the bottom of the list, with the excellent selection of Teaching Resources, such as the link to Internet TESL Journal Links Page, which contains an "extensive, well organized set of links to scholarly and pedagogical resources." The lists of Professional Organizations and Scholarship and Policy Resources are also worth a visit, each detailing excellent resources from around the Web.
