The Defense Learning Institute Foreign Language Center offers a number of open source tools that assist independent learners in  familiarizing themselves with the culture and language of many countries.

Global Language Online Support System (GLOSS )
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.
