I have never taught from an online commentary, but I am persuaded that this text would be an effective way to do so. The different types of information that the student needs are easily accessible, the format is pleasing and intuitive, and the level of the notes is appropriate and rigorous. The printed version is successful in itself, but the appeal of the online version is manifest. My pedagogical habits would have to change somewhat if I were to teach from an online commentary (would we all have screens in front of us? would we also still want to have printed texts to annotate?), but this is precisely the sort of online teaching resource that encourages experimentation with new formats and methods. As a pedagogical platform for teaching Latin with digital materials, this text is visionary in its design.
If you are experimenting in this way, please leave a comment and let everyone know how it’s going!
