It makes access to the computers easier, particularly for mobility impaired students. It provides the best line of sight for the students to watch the teacher, and vice versa. It is relatively quick for the teacher to move to a specific student, or to observe what is on each student's computer screen. These factors make it easier to keep students on task and to provide effective help. When you refer to "desk chairs" in the middle, I am imagining the type of chairs with an attached (often foldable) writing surface. If this is what you mean, I would argue against it. These chairs can't be used comfortably at the computer, and having one chair for computer work, and another for "regular" class work wastes space and money. Our most successful lab has swivel chairs with high quality casters. These allow students to quickly pivot their attention from computer to teacher to room center, and to roll their chairs for pair work or other flexible arrangements. The decrease in noise as students move their chairs, compared to chairs without casters, was an unexpected but significant benefit. We argued against the large central work table that was favored by some teachers in the planning discussions. We opted for foldable, removable tables. As expected, all the teachers prefer having clean open space in the middle of the classroom, and we almost never get a request to set up the tables. Students do their "regular" work in a circle or in small groups, while sitting in their swivel chairs, with no writing surfaces, other than their notebooks and laps. We have not had complaints. Tasks that require extensive writing are not likely to need as much interaction, so students can use the surfaces next to the computers. Your usage and teaching tasks may be different, but I suggest that you consider retaining maximum flexibility, and experiment with leaving the middle of the floor open. Given that you want space for 25 students, the size of the room will be governed by how much width you give to each work station. If you can spare four feet of width per student, it is much easier for two students to work together on the same computer. This kind of collaborative learning can be very effective for some pedagogy. Some labs have as little as 28" per station, but I think of 36" as a minimum. The number of square feet needed depends on how you lay out the room. A 36' square room could accommodate 25 student computers comfortably, with space for a teacher's station at the front. This room would have 1296 sq ft, a little over the 1200 sq ft that you envision. Changing the dimensions of the room to 40' by 25' would let you put the same number of computers in 1000 sq ft. If you can work with a trapezoidal shape to the room, you can cut the sq ft even further. You will have to experiment with your design. We find it essential to have some work stations available for students when a class is in session. The more your computer lab is used as a classroom, the more you need an additional space for drop-in students to do their work. Even two extra computers can be a big help. Three or four would be better. It depends on the kinds of assignments given and the language learning software which you have available. There is never enough storage space. Design some in, if possible. Flexibility, storage and room for expansion would be three things that I would strive for in any installation. Of course, there are always compromises and limitations.
