It is much more often the case that there are the right number of classrooms, but they are lacking in some other way which impacts their utilization. This could be something simple that is easily remedied (it is just that no one ever asked), or it could be something very complex. Maybe technology is substandard. The seat count is not right. Furniture and flexibility provided in the room does not suit the needs of the pedagogical approach. The room is in a building at the edge of campus, or simply not in the same building as the department. There are never whiteboard markers in the room. The only doors are at the front of the room, so late arriving students interrupt the lecture. The room isn’t scheduled on Monday mornings or Friday afternoons because those are unpopular slots. It is important to dig deeper at these comments from campus constituents to reveal underlying cause and effect.
