This paper reports on the experiences of international MBA students following a hybrid design for a business ethics course, which combined class-based lectures with "out-of-class" discussion supported by asynchronous communication tools. The e-learning component of the course was intended to generate discussion on the ethical assumptions of course participants, with each individual required to post a mini case study reflecting an ethical dilemma which s/he had faced at work. Using questionnaire and interview data, we report on the learning experiences of participants following this experimental course. The results reveal a high level of intercultural dialogue between participants, with adopters showing greater awareness of their individual cultural biases in their case writing, a direct consequence of the on-line feedback and case discussion. These findings indicate that asynchronous tools have much to offer business ethics students, supporting ideas sharing and the exchange of cultural perspectives outside the physical boundaries of the classroom.
