The e-evolution of microscopy in dental education.

Recent technological innovation has now made it possible to turn the computer into a microscope. This has entailed a shift from light microscopy to virtual microscopy. This development then foregrounds the issue of the pedagogy involved in this move from the analogue technology of the light microscope to the digital, computerized instance of virtual microscopy. In order to address this issue, undergraduate students enrolled in the Bachelor of Dental Science program at the University of Queensland School of Dentistry were surveyed to ascertain their preference for light or virtual microscopy. The value of this study is that it was conducted on the same cohort of students in two separate courses in 2006 and 2008, giving it longitudinal validity. The responses were overwhelmingly in favor of virtual microscopy. When it came to completely replacing the light microscope with virtual microscopy, however, students were much more ambivalent about such a wholesale change although this was less of an issue in the senior year. This shift from light to virtual microscopy signals larger changes in the tertiary sector from print-literate to electronic forms of knowledge and from teacher-centered to student-focused frames of learning. In short, we are in the midst of the e-evolution of microscopy in dental education.
