摘要

New media are well suited for extending the range of communicative settings. Many of these settings are applied and tested for educational purposes (e.g. two-point communication via e-mail, virtual seminars), especially in the field of distance education where flexible and user-paced access to learning environments is given high priority. A growing body of empirical investigations in the field of net-based learning reflects the need and the necessity to describe, classify, and improve potential learning settings. Therefore it seems important to develop models and frameworks that integrate existing results, help generating relevant hypotheses, and guide future research. Existing models in the field of computer-mediated communication are somewhat limited because they either do not address learning explicitly or use very broad levels of analysis. E.g., there is a lot of empirical evidence from the social psychological domain that investigates issues as social presence (Short, Williams & Christie, 1976), social cues (Kiesler, Siegel & McGuire, 1984), or task-media fit (Daft & Lengel, 1986; McGrath & Hollingshead, 1994) on a very fine-grained level, but most of these findings are related to computer-mediated communication for organizational purposes (e.g. group decision making) instead of computer-mediated collaborative learning. On the other hand, models that are specifically designed for net-based learning (e.g. Eastmond & Ziegahn, 1995; Hiltz, 1994; Velayo, 1994) address knowledge communication and knowledge acquisition of groups on a very molar level. Empirical data in this tradition (e.g. login times as general measures of user participation, questionnaires on media acceptance) are often too general to address the learning processes themselves.
