Adopting Cummins' model of intervention for collaborative empowerment, this study reports on a transnational project that examines (1) the effectiveness of enhancing critical cultural awareness by engaging culturally diverse university students in online discussions and (2) students' perspectives on understanding different cultures through mass media and technology advances. Thirty-five Canadian and 47 Hong Kong university students participated in the project integrating aspects of multicultural education. The results of thematic analysis of the scripts of their postings showed that the innovative learning environment provided students an authentic and constructive intercultural learning experience. It enhanced their cultural sensitivity and competence and reinforced their critical awareness of various texts, information, and discourse arising from the use of new technologies. The results indicated that, when paired with appropriate instructional design, Web 2.0 technologies have a great potential to facilitate multicultural education and practices through effectively forming transnational learning communities that harness the strengths of diverse students.
