81). Despite this universal endorsement, the efficacy and pedagogy of lab-based education has been criticized for a number of shortcomings, including triviality, repetitive, rote ‘recipe’ following, inadequate supervision, and a poor return on student time invested (Kirschner & Meester, 1988). The logistical problems associated with developing and delivering lab experiences at a distance further exacerbate these challenges. However, distance educators are nothing if not inventive and persistent, and they have developed a variety of techniques and designs (see chapters in this volume) to address these problems while maintaining high levels of accessibility — the raison d’être for distance education programming.

Similar findings were noted when comparing students participating in remote videoconferencing with students attending on-ground lectures (Lou, Bernard & Abrami, 2006). The fact that all instructional resources are available for online and on-ground learners implies that there is nothing unique about online instruction per se and the subsequent learning that occurs or not. indd 29 • Chapter Two • 29 14/12/09 5:39 PM Second, some initial and tentative practical implications vis-àvis the relationship between perceived course difficulty and dialogic behaviour have emerged.
