The training we received is still the core of how I think about everything. It was all about needfinding, methods for exploring the problem and solution space, iterating with low cost mediums and moving to higher cost only as needed for more information or production, things like that. Things that relate to human needs, understanding them, and seeing how the things you make relate to them.
Visual design was a minor part of the curriculum, we had a few art requirements. But it wasn't the core.
It is sad that design means visual perfection and smooth animations. Design is really about uncovering novel ways to improve people's lives, and doing so in the simplest way possible. It doesn't necessarily even relate to interfaces.
