GLOSS (Global Language Online Support System) is one of the resources available through the Defense Language Institute. "GLOSS lessons are developed for independent learners to provide them with the learning/teaching tools for improving their foreign language skills. Reading and listening lessons are based on authentic materials (articles, TV reports, radio broadcasts, etc.) and consist of 4 to 6 activities. In-depth Feedback accompanies all motivating tasks, providing learners with thorough explanations and tutoring just like an attentive and experienced teacher would do. GLOSS Certificates provide documentation of work accomplished. With more than 7,000 lessons, GLOSS is a valuable resource in maintaining and improving language ability and proficiency."
