Learning effects of asynchronous learning networks: a comparison of groups and individuals solving ethical case scenarios

The field experiment described in this paper explores self-reported learning and actual learning outcomes when asynchronous learning networks (ALN) vs. manual methods are used in the individual and group solution of ethical scenarios. A 2×2 factorial design crosses two modes of communication (manual vs. asynchronous computer conference) and two types of teamwork (individuals working along vs. individuals working in groups). The results of this field experiment suggest that the use of ALNs can be as effective as a traditional or face-to-face medium for conducting collaborative activities, such as the discussion and solution of cases in groups. Teamwork combined with asynchronous support can enhance the perception of learning. However, individual work in interaction with online materials negatively affects the perception of learning and subsequent exam performance
