Results of the implementation of a virtual microscope in a course of histology

[EN] The course of Anatomy and Histology is studied in the first year of Dentistry at the University Cardenal Herrera CEU (Alfara del Patriarca, Spain). Its practices consist on choose freely six different tissue samples and draw their most representative features. These practices were made by optical microscopy until 2014, and in 2015 was introduced the virtual microscope exclusively. The aim of the study is to test whether this new teaching method has improved the quality of exercise and the understanding shown by students. First, the best exercises of both years were chosen, and from them some drawings from the same tissue were compared. Some tissues which samples for optical microscope were hard to obtain, were drawn for the very first time thanks to the virtual microscope. Also, with the virtual microscopy the drawings contained more details and definition. The understanding of the structures improved, shown by a more functional, detailed and defined vision of the tissues. The labels of the virtual microscope helped to the self-study and avoided the loss of unnoticed structures. In conclusion, replacement of optical microscope by the virtual microscope is a teaching improvement and facilitates student learning.
