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. With more than 5,000 lessons, GLOSS is a valuable resource in maintaining and improving language ability and proficiency.
