Connecting online learners at a distance: the promise and challenge of using metaphors as reference points

Abstract

This experimental study probed the effectiveness of three kinds of objects (videos, theories, metaphors) as common reference points for conversations between online learners. Outcome measures were learners' levels of tacit-knowledge (TK) of specific concepts related to their practice (teaching). Learners' level of detail-focus was examined as a mediating variable. Results showed a positive effect of detail-focus within Metaphor condition for two of three TK indicators examined. Implications for online conversation design are discussed.
