Magical Academy game- freeform or D&D?
I'm going to go out on a limb here, because while the setting is very different, the mechanics may be what you're looking for: Invisible Sun by Monte Cook Games. The whole premise is that the characters are scholarly magicians of various sorts (one is wizardly, one is sort of a free-form sorcerer, one is a summoner, one is an artificer-type, and one is a free-form magician) and the pace of the game assumes lots of research, and even exemplifies and rewards the nitty-gritty of finding components, books, teachers, or unusual beings in order to grow in magic. Magic is the central conceit of the game, and combat is very rare and often deadly (and it mostly assumes you are not getting into it unprepared, because you should have been doing research). You gain secrets of magic and learn special talents as you grow, and can choose to focus on your academic side, or your talent side (or both, if more slowly). The game assumes you already start as low-level masters of your craft, so it's about growing into a truly powerful magician.
While the setting is unusual and surreal, the mechanics could easily be transferred to Eberron. There are several sub-systems in the game that can be ignored to simplify it (relating to the philosophy inherent in the default setting), allowing for a more pure magical research/academy experience.
