The NIFLAR project aimed to enrich foreign language programs through blended learning using video conferencing and 3D virtual worlds. Its objectives were to promote interaction and study its added value. Partners included universities in Europe and Latin America. Tasks were designed for Dutch, Portuguese, Russian, and Spanish based on pedagogical principles. Research found that virtual interactions enhanced learning processes and increased motivation by developing competence, cultural awareness, and willingness to communicate with native speakers. Meaningful interactions depended on adequate integration and effective tasks addressing learner needs.
