Teachers’ impact on dental students’ exam scores in teaching pathology of the oral cavity using WSI

We have developed and evaluated a user-friendly on-line interactive teaching and examination system for Pathology of the Oral Cavity. Abandoning the use of conventional training microscopes and glass slides since 2005, we decided to rely on virtual microscopy to facilitate learning of oral cavity pathology to dental students. Because of a high number of new students enrolling every academic year, students work in groups supervised by different teaching assistants with heterogeneous teaching experience. The aim of this study was determining whether in this context the teacher has still an impact on students’ exam scores.
